The distance between discs and even the shape at edge of the disc have to be tapered and also having a Vacuum at the exhaust will increase it's efficiency. Most people who build them do not build them to Teslas Specs. That's the bottom line... Tesla stated it can reach 95% efficiency but you have to build it right and for the application intended.

Warren Rice of Arizona university has tested tesla turbines from tesla' specs to 97% efficiency, Tesla claimed 98%. As far as a "specialised" generator being needed, you could use an old washing machine motor with a basic belt setup, give it a wee push to get it started and it'd run fine, 1000's of alternatives also that'd work simply & cheaply. And if someone was heating their home with a fire & producing steam to run a tesla turbine, or even just heated air, then the efficiency numbers would mean jack squat to them.
Scoobysdooby a belt set up that can convert 100k rpm on down. mmmhmm. Teslas turbine pretty much sucks. The patent is expired, its wide open for use. If it was so great, people would use it! But, its not! Just because the man got some things right, did not make him infallible. Brilliant? Sure. Crazy as fuck? The man did marry a pigeon.

OK, so lets do some math.. I'll use standard measurements.. At 5454RPM, torque = power in HP.. Is 1 ft lb easy to stop with your hand? I think so, so that's 1 hp already, or 745W.. that's going far faster than 5500RPM, so 1 KW is quite a reasonable estimate, even if it does make less than 1 ft lb of torque
actually, Brian, horsepower is a measure of energy over time, or "power". 1Hp = 746W. You can use torque to calculate horsepower, but that's because it's (2*Pi*Torque*RPM)/10,500.
"Energy" is a scalar quantity and torque is a vector. In other words, torque is "effort" and so you are correct in that its not actually energy because you can apply torque (effort) to an object and if its not moving there is no energy. My original statement, though off, still functions well pragmatically. Torque over time = power. If there is no movement (therefore no time), regardless of how much torque (effort) is applied, then there is no power. At the end of the day its all just semantics.
Awesome vid thanks for sharing. I would love to know more about this. Have you got an optimal PSI/RPM ratio and do you think that turbine would have the torque to turn a couple of stators or a high RPM motor shaft?

Well actually because they're under such low friction it's not very difficult to stop them. your hand is more than capable of providing significant drag stop it from functioning.

What did you use to build the Tesla Turbine on the inside? Also, could you be so kind as to list how you're creating the steam power (what construction is your boiler using)? And, if you're using a "closed-loop" system for the final turbine-version. I'm planning-on using old hard disk stacks, & faulty CD/DVD's & their spindle cases to make mine. But, I need to know how you're controlling the amount of steam getting into the turbine...or, more-or-less, where you've put your valves, what kind of valves you've used, & hopefully how the valves are being opened to pipe thru to the turbine. Not sure if you're just heating the steam itself in a tank, or heating a tank/cylinder separately, using a valve to release "controlled" amount of water at a time, into the heated cylinder, on contact it turns to steam, & then goes to turbine, condenses & goes back into the heated cylinder, or back into that separate water container I mentioned. Sorry this is a long message, but I'm a beginner with Tesla Turbines, & is prefer to ask more experienced people first, rather than cause an accident at home which would make Hiroshima only look like a whoopie cushion! Cheers & Thanks!
Awesome Job. Nice to see the creative resiliency of the human spirit. Try insulating your pipes so that they don't lose any heat on it's way to the turbine...might have better luck with it not condensing until it's outside the turbine.
You could stop the spinning with your fingers at 0:23. which seems like it has little to no torque. Or was is still warming up and would be much harder to stop once more steam started flowing?
Looks cool. Would suggest insulating the pipes so you aren't losing heat, if you haven't already. I sounded loud on the video... do you think steam is a "neighbor friendly" source of green energy, or is it possible to suppress the noise?
Yes and presumably, as well as providing power, this machine could also be used to purify low grade water - you could condense it and use it as a clean source of drinking water. Two birds with one stone.
@JenMichel100 Not sure what you mean. Around 1kW shaft power is a lot lower than the ~40kW steam I was blowing through the little turbine. Around 0.34 foot pounds of torque at around 20,000 rpm is around 1kW shaft power. I didn't instrument this so I could be off a bit. But yes, it's in the kW shaft power range.......albeit at a dismal ~5 percent thermal efficiency of getting energy out of the 40kW of steam.
Not much power output, would you gear down the output for some torque? Seems you need either positive displacement, more surface friction on your turbine or some serious gear reduction to do anything other than spin an unladen wheel... ~( ,m,)~
What about using a passive, gravity fed solar water heater to boil the water? With the right set up it could boil the water for you with out the need to burn wood chips.
He throttled it way down before he did that. If he tried stopping that wheel at full power it would have sliced his hand apart. One Kilowatt of power is nothing to sneeze at...
1kw is not that much. I have a small drill press at 1.2kW and i can stop it with my hand while using a welding glove. Is not hard to stop, it often stops while drilling.
@@aion2177 yeah it's not that much power really, but it also depends on how fast they are spinning. My point was pointed more towards the fact that the wheel was spinning at many thousands of RPMs at full power, and being as big around as that rotor was, it's radial speed was around 500 mph. Wouldn't matter if the outside edges were polished smooth as a mirror, it would slice through your hand. If you had some kind of protective device like very thick welding gloves as you said you might get away with it though, since as you mentioned 1kW isn't all that much power.
In the 1800's an experiment was conducted to decompose water. People of the time heat up a rifle barrel to 600 degrees, and pump steam through it. A chemical conversion occurs from the heated iron and steam contact. The output is hydrogen gas. This may be a key factor to include when producing a successful new powerplant.
this is awsome ... you should trie to make a device to capture the used steam and put it back into your boiling water. this will be more efficient because the steam you capture will already be hot befor it goes into the boiler.
run the PMG to Capacitors and then to a battery bank. then invert to your house mainbreaker. two 120Vac invertors hook up to main and run 220Vac. The generator needs to spin under no load, so charge up Running caps then discharge them to battery bank, Even pass thru a diode before capacitors. Tesla made his Capacitors from leydon jars then he went on to his owm invention of mica. Simple plate capacitors can be used too.. Thanks for the cool Idea! Now I can heat house, water and get free power !
@JenMichel100 I didn't hook this up with instruments to measure the actual shaft power. But I do think it was producing around a kilowatt of shaft power. That said............I was pushing 40 kW of steam power through it. So the efficiency is really low, like 5 percent or so. The turbine was spinning a bicycle brake rotor at up to 20,000 rpm and you can see how it was working as a powerful fan blowing the steam outward. So yes, it was producing around a kW. rt
Holy cow. Not a lot of torque but wow! Is it possible to make a closed system for the steam? Maybe a cooling tower that would allow thw steam to condense and fall back into the water tank? Very impressive!
one important fact, if anything can operate at very high rpm, you can always gear it down to get the torque you need. standard dc generators operate at 2,700 rpm, these boundary layer turbines can operate at 30,000+
During these runs, I was hiding behind the boiler in case things flew apart.....so not sure where the dent in head would happen. One thing's clear though, these runs were more power than this turbine could safely be run at. rt
Hi, I wanted to know if it was possible making flammable gas fire inside the discs with those upcoming laser igniters to have plasma combustion engine ?
How many disks? Would be interesting to see it coupled to a dynamo to see what kind of electrical power can be generated. Superheated steam would be another choice and collect exhaust for secondary use to increase overall efficiency of the system.
have you looked at the atmospheric vortex engine. the swirl from the exhaust of your turbine would match well with that. let you get extra power out of your turbine.
By adding a proper wheel and timing chain connected to a generator, this idea might work. Unfortunately, due to the "big noise" involve with this invention.... a sound proof compartment and a chimney will solve the problems of noise and smoke pollution. Just a thought!
Kevin, a well-tuned Tesla turbine can get up to 65% efficiency, so yes, conventional turbines can be more efficient. However, Tesla turbines are simpler, easier to make, easier to maintain, and comparatively cheap. Perhaps a bit more R&D would help, but not bad for a design that hasn't changed much in 105 years, wouldn't you say?
Well, Paul, you do have a good point. The issue with a tesla turbine is the remarkably low torque output, which is a huge reason why it hasn't seen much manufacturing. Part of the issue is that in the 105 years since it was patented (circa 1913), it hasn't been used for much more than garage experiments and cool demos. It could be used for a turbocharger or a generator, but it's gotta become more popular first.
Technically, Klingende, the amount of work energy is the cumulative effect of net force applied, which can factor into applicable torque. This is more or less from Calculus-level physics. The high RPM, if the discs are heavier towards their rims, would mean that the rotational kinetic energy of the turbine would be fairly high (and that energy is the work energy. Even in this demonstration, the amount of work energy available is very good, considering the high RPM). The main issue is that it has low torque at low RPM and moderate torque at higher RPM. If the discs are well balanced and weighted at the rims, the torque would be quite satisfactory. With the right construction and a gearbox, it would yield a functional amount of torque, but you are correct in that a tesla turbine in direct drive is not enough of a powerhouse to overcome static conditions. The flywheel on the front is definitely useful in helping the system work. It's not exactly going to drive the most torque-intensive units in the world-- generators are a good example of a system right up this design's alley, assuming you can crank-start it or hook it up to a gearbox, and while its performance isn't perfect, at least it still has the benefit of being so cheap that practically anyone can make one for less than $50 at the very least (CD turbines are even cheaper).
i have a few questions regarding this turbine, how many discs do you have, how far apart are the discs from one another and do you have any calculations behind this design??
@TheTeslaJet Sounds faster than it is due to vibrations. I have a tach. But it's a bit scary getting close enough to get a reading. I think it's hitting 20krpm at times, but mostly down in the 10krpm range in the videos. It's spinning that large diameter 8" bicycle brake rotor that's acting like a rather powerful fan at these speeds. You can see the difference in steam exiting on the two sides (both exit sides open). Not enogh power to overcome starting torque on a PM alternator though.
@floridacoder Yes. Steam turbine power can be "neighbor friendly".......though not this turbine. See my other video of the new turbine "Sound Check..." to see how quiet the turbine can be. Ultra quiet power system is the goal, and the fuel is green, so, yes, this is environmentally friendly. Ultimately the fuel will come from some wood, some agricultural waste like straw converted into a form of pellets, etc. Lower cost than propane or diesel and lower carbon footprint.
Nice construttion. But, there seems to be a lot of steam leaking out? This is not a closed Stirling system? If steam is leaking out, then there is need for water comming in from outside the construction = not so efficient and also more of maintainance demands.
Are you really running steam temp at 200C? That would be like 225 PSI operating pressure, correct? Seems impractical for most people to maintain a safe operation over time without constant supervision. For any of your steam options how will you address mineral deposits in the boiler? It appears that you are using a coils system so the buildup would be inside the tubes.
neat but how will it react with the restive force a generator, it doesn't seem to have a lot of torque value seeing as you were able to stop it by hand great experiment btw
you can capture the used steam and put it through 1 or more additional stages to increase the efficiency, you can also install a heat differential engine to use the waste heat the turbine unit is absorbing.
a motorcycle stator setup might make more sense than a car alternator for this turbine, less moving mass and you could pretty easily retro something from the multitudes of salvage bikes out there.
Greetings. I wasn't able to fully instrument this turbine to get good numbers under the high drive power of the steam boiler. I was able to get data using a string, weight (mass) and air compressor. The turbine in that set up produced about 150 watts. This was without the steam. The torque was around 0.10 pounds and rpm around 25,000 rpm which works out to around 120 watts for a typical run with around 180 being the best run I could manage using the air compressor. The steam boiler had a hugely larger amount of power available. At least 10 times the power of the air compressor air. I added the brake rotor to act as a fan to dissipate the rotor energy and even so it nearly flew apart. The 1 kW power output is an estimate. But the steam boiler was producing 20 kW steam output. That was easy to measure based on water flow rate, steam pressure, and steam temperature. This all means that my best guess is that the turbine was producing around 1 kilowatt of shaft power, all of it going into blowing air around and making bearing noise. But that means that with air bearings and a high frequency PM alternator, the turbine should generate around a kilowatt of net power under those conditions. This is of course still pathetic............20 kW of steam to generate 1 kW of electrical power. It's an experiment with a tesla turbine. My goal was to build a higher efficiency turbine for home power generation but funding didn't materialize, so this is what I was able to do. See the nearly silent turbine prototype as well. rt
Thanks for the sharing the data. Reading some of the comments below by people who assume "facts" that are not facts I could only imagine what Tesla went through when this invention threatened the turbine & reciprocating manufactures of his time. I have read all of Tesla's patents and all the other reported statements he made to the press and did not find anything on turbine geometry like different diameters, numbers of discs, etc, as they relate to a desired amount of power or torque for a given RPM. I read from him "of a suitable diameter" and such statements. Problem is that he states the turbine can built by anyone with access to a metal shop - and he is right. Other statements he makes such as working with compound turbines lets me know he did not broadly publish everything he knew. So,I have a few questions if you don't mind: 1. Did all 20 kW of the boiler go into the turbine? I thought I heard you say in the video that you were holding back the steam so as not to damage the turbine. 2. What if you insulated the steam lines and the turbine casing? Without any other modifications how much more power could be realized at the shaft? 3. Using the same boiler and increasing the size of the turbine to say 18 or 21 inch discs and insulating the steam lines & casing would you achieve higher power output and lower RPM? How much more power at what RPM? From the video I could see a lot of uncaptured steam from the exhaust. I realize that the answer to #3 may well be the result of more work/funding you also spoke of. On that subject, how much funding and time would it take?
Very nice demo.. Recycling the water would also save. A simple screening were the steam would impinge, might have to be large, 3'x3' or so.. Just a thought, every time I see something I want to try it out.. LOL
+woodfirepower You should have vent holes in the front and back of the casing. I would do a test run with an exit hole/pressure the other direction. Make sure everything is balanced for the operational speed. I think you need to make the whole thing about twice as big all around, you never achieve a balance between the interta of the steam, and the RPM, you should be shooting for a turbine that runs into the 80k+ range. You could make a lot of energy out of that with a transmission and a generator.
Work is force x distance in a linear situation, which is torque x angle subtended, in rotational systems. Power is force x speed, or torque x rotational speed. A puny amount of torque, times a high rotational speed, amounts to a lot of power. It would appear to me that the high rotational speed is certainly present here. Furthermore, the torque is probably higher at the high speed, because the steam had been turned down to get the slower speed that was stopped by hand. Lots of steam later.
Because it has zero torque and under load it would stop. he literally stopped it with his hand at one point. this is the equivalent to a kid blowing compressed air at a fan and calling it a turbine. hes not wrong but he is an asshole
In a closed loop vacuum system, water boils at 30c and returns to liquid at 29c you just need a condenser and a an electrical generator with low impedance and this guy could have a steam electrical power plant for everything he needs running off the heat from the sun or his home fireplace in winter.
I've driven forklifts for years and was wondering if a small hydraulic pump forcing hydr. oil around a cylinder in each wheel the possibility of powering a car that could do standard road speeds of current gas driven cars?
Yes, you can stop 1kW with your fingers. Power results from torque times speed. So a small torque that fingers can stop, combined with high rpm, makes 1kW of power. Notice that it took me a while to slow it down with my gloves.........fingers got hot from friction. rt
Wow that is a great turbine. I have built about ten small tesla turbines but had no access to a machine shop. That plume of vapor and rain of condensed steam is an obvious sign of power. Have you considered piping the exhaust steam through copper tubes and pre heating your boilers input water? if so how did it work? if not ...Why not?
There are tons of Telsa Turbine links all over youtube, and every one of them just show a hose coming in from "somewhere off camera". That hose is attached to a pressurized water or steam supply that is generated by a POWER SOURCE conveniently left out of the video. Newsflash: It takes POWER to generate either pressure or steam.
efficiency isn't great, BUT to be fair, the steam could be used for heat, as it condenses you could feed it back into the furnace or collect it as drinking water (it's been boiled, so it's clean) and the heat from the furnace could give you hot water and heating.
Hey bud listen, sun may not shine at night, but if you're willing to concentrate it onto some stone or other dense material, you can contain it effectively to keep making steam all night long. It's only a matter of how much polishing you got to do to get those aluminum mirrors working efficiently...
how could this power a generator? The steam seems to slip right through when a load is applied to it as you demonstrated when you slowed it down with your gloved hand.
Maxwell Jaxwell Lightweight magnets mounted to the brake disc. Then an assembly of small generator coils with light magnets behind them put in proximity. You don't need high torque to produce high voltage when you have speed like that. Mount a 12in disk on it with 1in magnets. That's about 40 magnets. With coils that produce 3 volts at .5 amps you could keep it at low torque, and still be putting out an ac current at about 27 kHz. With the right circuits you could drop that down to 60 Hz at 450 volts/0.5 amps. Bring that down to 110 volts, and up to 2 amps and you could run most household energy efficient appliances. It's all a matter of turning a lot of weak power into a little bit of strong power... And you could always use the exhaust to run another turbine. It would be weaker, but would still contribute. I could go into more detail, but I'm not trying to write a novel here. Hope this helped.
That's more than enough for a TV, computer, or other low usage device. Maybe not a fridge, or microwave, but like I said, the exhaust could power another generator. And one boiler could power multiple setups at once. I understand one of these isn't enough to power an average power hog modern home, but it is viable as an energy source.
If you have the right tools already, and an old hard drive, it's not really that expensive. And if you're talking about fuel, you could always replace the wood fired boiler with a passive solar one, made with a fresnel lens from an old RPS TV(so many for free on craigslist), or at least supplement it with one for daytime use. Things get a lot cheaper when you use a little bit of ingenuity, and whatever free resources you can muster.
steven spall the magnets and coils create resistance. You seem to think that reducing the weight of the magnets and coils will matter. It won't.If the magnets and coils are so small that they would not generate resistance then you would not generate much electricity. This is why those windmills in wind farms are so big. The very large blades of the windmill create a lot of torque. Like a lever, the longer the blades are the more torque you haveThis device generates almost ZERO torque.
PS I would cage the rotor for sure as that will be failure point first, a school suggested that that has a couple of these. Disks will break free of shaft before case busts.
try placing a pressure regulator on it before it goes to turbine place divider inside mechanism and drill hole and tip to recycle water back to origin to to be reused if done right you should reduce the amount half to refill tank of water... it would be continuous as far as torque goes should improve if the systems is sealed but would recommend a pressure valve also This is just my opinion I like it and i'm trying to find most efficient way of producing energy I want to be 100% off grid one day
So is the idea to turn the outside bicycle brake plate in to a A/C generator by engineering magnets in to the plate and positioning brushes around that plate to generate power rather then attaching a clunky generator motor to the shaft.?/ If so I like it the A/C plates can be multiplied and it would seam there would be less resistance. you could expand or retract the size of the turbine engine to your specific need of power.
Probably will have to say this a hundred times.....power is torque times speed. So small torque times high speed equals larger power produced. You put a low torque alternator on the shaft that can handle the high rpm, and you can get good power. Again, that one was probably generating around 500W shaft power. but the rotor can be dramatically improved, increasing the torque and speed capability both. Just takes time and money to build next versions. rt
I am planning a closed circuit solar convection heater system, where the liquid would be recirculated, vapor collected & fed back to a small holding tank. I plan to start with water, but plan to upgrade to liquid mercury in the future. I plan to turn a comercial 5KW generator with it. The only literature I found using mercury in Russian but it does mention the turbine blades may become unbalanced because mercury is so much more dense than water. One report also mentions that "some gold appeared to coat the turbine blades". I am sure this is a mistranslation otherwise everyone would catch on this real fast. I suspect it is some kind of golden color that is produced as a reaction between mercury & whatever the material the turbine blades are made of. Any comments / words of advice? I am a scientist & a physician, I fully understand the dangers of working with liquid mercury, mercury vapor etc. What I need is more mechanical advice. Thanks in advance. Tony from sunny & hellish hot Arizona.
It could probably turn a proper size generator. It wouldnt have acceleration like this probably but I believe that it could reach high rpms. It would be real fun to have your own powerplant at home.
I think you mean condenser. A large steel plate with cold water on the opposite side would condense most of it. Don't want to restrict steam outflow much.
How much per kilowatt, with varying fuel, and what is the estimated lifespan of this unit, which would include a maintenance schedule, because no machine can ever operate under any conditions without periodic care.
Asylumescapee69............. What you say sounds correct. I too thought one could do something like you suggest. But if you do the math on energy storage, you'll find it really doesn't work that way. the one path that can perhaps work is to capture sunlight in water at a lower temp, then run a Rankine cycle using "Freon" or other lower temp boiling fluid, boiling it at warm to hot water temps. A kilowatt hour is a lot of energy and homes tend to use 24 of them per day or more (in US) rt

With that little torque ( you can stop it with your hand), it will not produce alything like 1 KW. More like 1W
OK, so lets do some math.. I'll use standard measurements.. At 5454RPM, torque = power in HP.. Is 1 ft lb easy to stop with your hand? I think so, so that's 1 hp already, or 745W.. that's going far faster than 5500RPM, so 1 KW is quite a reasonable estimate, even if it does make less than 1 ft lb of torque
Horsepower is a measure of torque over time. RPM is the time aspect. Little torque and lots of speed means good power. Gears do the rest.
actually, Brian, horsepower is a measure of energy over time, or "power". 1Hp = 746W. You can use torque to calculate horsepower, but that's because it's (2*Pi*Torque*RPM)/10,500.
"Energy" is a scalar quantity and torque is a vector.
In other words, torque is "effort" and so you are correct in that its not actually energy because you can apply torque (effort) to an object and if its not moving there is no energy.
My original statement, though off, still functions well pragmatically. Torque over time = power. If there is no movement (therefore no time), regardless of how much torque (effort) is applied, then there is no power.
At the end of the day its all just semantics.

I agree. A device that can produce power and purify water is an off-the-grid home run!

How do you produce the steam (how big is the boiler, what's the heat source etc) and how did you measure the power at the shaft?
Well actually because they're under such low friction it's not very difficult to stop them. your hand is more than capable of providing significant drag stop it from functioning.
What is the temperature of the steam and the output power? I want to find its thermal efficiency. Looks promising.

Awesome Job. Nice to see the creative resiliency of the human spirit. Try insulating your pipes so that they don't lose any heat on it's way to the turbine...might have better luck with it not condensing until it's outside the turbine.
Amazing - you can stop 1kW using only 2 fingers?
Any videos of this making some power?
How did Blades hold up as far as far a spall abrasion . How often on the rebuid on venturi and viscosity disc ?
You could stop the spinning with your fingers at 0:23. which seems like it has little to no torque. Or was is still warming up and would be much harder to stop once more steam started flowing?
Looks cool. Would suggest insulating the pipes so you aren't losing heat, if you haven't already. I sounded loud on the video... do you think steam is a "neighbor friendly" source of green energy, or is it possible to suppress the noise?
Yes and presumably, as well as providing power, this machine could also be used to purify low grade water - you could condense it and use it as a clean source of drinking water. Two birds with one stone.
@JenMichel100
Not sure what you mean. Around 1kW shaft power is a lot lower than the ~40kW steam I was blowing through the little turbine. Around 0.34 foot pounds of torque at around 20,000 rpm is around 1kW shaft power. I didn't instrument this so I could be off a bit. But yes, it's in the kW shaft power range.......albeit at a dismal ~5 percent thermal efficiency of getting energy out of the 40kW of steam.
Not much power output, would you gear down the output for some torque? Seems you need either positive displacement, more surface friction on your turbine or some serious gear reduction to do anything other than spin an unladen wheel... ~( ,m,)~
What about using a passive, gravity fed solar water heater to boil the water? With the right set up it could boil the water for you with out the need to burn wood chips.
I like the set up and would like to know in more detail what you did. But, have you thought about encasing it and to recycle vapor through condenser?
"Teslajet turbine 1Kw" *stop with hand*
tesla turbines have low torque but high rpm. 1kw at 30 000 rpm is equal to 0.2 pound feet of torque. it's not surprising it's easy to stop by hand.
@@renaudfensie3020 but he made a disclaimer in the title. Wheres the proof of those turbine generating 1kwh power
He throttled it way down before he did that. If he tried stopping that wheel at full power it would have sliced his hand apart. One Kilowatt of power is nothing to sneeze at...
1kw is not that much. I have a small drill press at 1.2kW and i can stop it with my hand while using a welding glove. Is not hard to stop, it often stops while drilling.
@@aion2177 yeah it's not that much power really, but it also depends on how fast they are spinning. My point was pointed more towards the fact that the wheel was spinning at many thousands of RPMs at full power, and being as big around as that rotor was, it's radial speed was around 500 mph. Wouldn't matter if the outside edges were polished smooth as a mirror, it would slice through your hand. If you had some kind of protective device like very thick welding gloves as you said you might get away with it though, since as you mentioned 1kW isn't all that much power.
@Hyenak all speed no torque?
In the 1800's an experiment was conducted to decompose water.
People of the time heat up a rifle barrel to 600 degrees, and pump steam through it. A chemical conversion occurs from the heated iron and steam contact. The output is hydrogen gas. This may be a key factor to include when producing a successful new powerplant.
this is awsome ... you should trie to make a device to capture the used steam and put it back into your boiling water. this will be more efficient because the steam you capture will already be hot befor it goes into the boiler.
Have you thought of using freon in a closed loop setup with a condenser. It take much less heat to drive a turbine.
Have you been able to gear down the speed to generator speeds?
Very nice.
run the PMG to Capacitors and then to a battery bank. then invert to your house mainbreaker. two 120Vac invertors hook up to main and run 220Vac. The generator needs to spin under no load, so charge up Running caps then discharge them to battery bank, Even pass thru a diode before capacitors. Tesla made his Capacitors from leydon jars then he went on to his owm invention of mica. Simple plate capacitors can be used too.. Thanks for the cool Idea! Now I can heat house, water and get free power !
@JenMichel100 I didn't hook this up with instruments to measure the actual shaft power. But I do think it was producing around a kilowatt of shaft power. That said............I was pushing 40 kW of steam power through it. So the efficiency is really low, like 5 percent or so.
The turbine was spinning a bicycle brake rotor at up to 20,000 rpm and you can see how it was working as a powerful fan blowing the steam outward. So yes, it was producing around a kW. rt
Holy cow. Not a lot of torque but wow! Is it possible to make a closed system for the steam? Maybe a cooling tower that would allow thw steam to condense and fall back into the water tank? Very impressive!
one important fact, if anything can operate at very high rpm, you can always gear it down to get the torque you need. standard dc generators operate at 2,700 rpm, these boundary layer turbines can operate at 30,000+
During these runs, I was hiding behind the boiler in case things flew apart.....so not sure where the dent in head would happen. One thing's clear though, these runs were more power than this turbine could safely be run at.
rt
If this was feed by a tromp and scaled up it would take it to the next level
Hi, I wanted to know if it was possible making flammable gas fire inside the discs with those upcoming laser igniters to have plasma combustion engine ?
yes its possible but there are some problems that are yet to be shorted
How many disks? Would be interesting to see it coupled to a dynamo to see what kind of electrical power can be generated. Superheated steam would be another choice and collect exhaust for secondary use to increase overall efficiency of the system.
Its fast does it have the power to work as a table saw or angle grinder
have you looked at the atmospheric vortex engine. the swirl from the exhaust of your turbine would match well with that. let you get extra power out of your turbine.
By adding a proper wheel and timing chain connected to a generator, this idea might work. Unfortunately, due to the "big noise" involve with this invention.... a sound proof compartment and a chimney will solve the problems of noise and smoke pollution. Just a thought!
But, conventional turbines are far, far more efficient, like 70%.
Why would anybody even want to use this?
Kevin, a well-tuned Tesla turbine can get up to 65% efficiency, so yes, conventional turbines can be more efficient. However, Tesla turbines are simpler, easier to make, easier to maintain, and comparatively cheap. Perhaps a bit more R&D would help, but not bad for a design that hasn't changed much in 105 years, wouldn't you say?
how long will this run before it craps out ,do to bearing failure?
Another demo of a Tesla turbine doing absolutely nothing.
Moonteeth62 they were meant to be run on gas.. look at his valvular conduit patent (actually read it) and you will see how it can be done.
What the fuck has a turbo got to do with a generator??
Well, Paul, you do have a good point. The issue with a tesla turbine is the remarkably low torque output, which is a huge reason why it hasn't seen much manufacturing. Part of the issue is that in the 105 years since it was patented (circa 1913), it hasn't been used for much more than garage experiments and cool demos. It could be used for a turbocharger or a generator, but it's gotta become more popular first.
I think you need your eyes checked. It's spinning at hight velocity.
Technically, Klingende, the amount of work energy is the cumulative effect of net force applied, which can factor into applicable torque. This is more or less from Calculus-level physics. The high RPM, if the discs are heavier towards their rims, would mean that the rotational kinetic energy of the turbine would be fairly high (and that energy is the work energy. Even in this demonstration, the amount of work energy available is very good, considering the high RPM). The main issue is that it has low torque at low RPM and moderate torque at higher RPM. If the discs are well balanced and weighted at the rims, the torque would be quite satisfactory.
With the right construction and a gearbox, it would yield a functional amount of torque, but you are correct in that a tesla turbine in direct drive is not enough of a powerhouse to overcome static conditions. The flywheel on the front is definitely useful in helping the system work.
It's not exactly going to drive the most torque-intensive units in the world-- generators are a good example of a system right up this design's alley, assuming you can crank-start it or hook it up to a gearbox, and while its performance isn't perfect, at least it still has the benefit of being so cheap that practically anyone can make one for less than $50 at the very least (CD turbines are even cheaper).
i have a few questions regarding this turbine, how many discs do you have, how far apart are the discs from one another and do you have any calculations behind this design??
Im staying tuned thats for sure
@TheTeslaJet
Sounds faster than it is due to vibrations. I have a tach. But it's a bit scary getting close enough to get a reading. I think it's hitting 20krpm at times, but mostly down in the 10krpm range in the videos. It's spinning that large diameter 8" bicycle brake rotor that's acting like a rather powerful fan at these speeds. You can see the difference in steam exiting on the two sides (both exit sides open). Not enogh power to overcome starting torque on a PM alternator though.
@floridacoder
Yes. Steam turbine power can be "neighbor friendly".......though not this turbine. See my other video of the new turbine "Sound Check..." to see how quiet the turbine can be. Ultra quiet power system is the goal, and the fuel is green, so, yes, this is environmentally friendly. Ultimately the fuel will come from some wood, some agricultural waste like straw converted into a form of pellets, etc. Lower cost than propane or diesel and lower carbon footprint.
Where can you purchase this Tesla Turbine ? Excellent demonstration. Tx .
Man, that little mother really moves!
Nice construttion. But, there seems to be a lot of steam leaking out? This is not a closed Stirling system? If steam is leaking out, then there is need for water comming in from outside the construction = not so efficient and also more of maintainance demands.
Are you really running steam temp at 200C? That would be like 225 PSI operating pressure, correct? Seems impractical for most people to maintain a safe operation over time without constant supervision.
For any of your steam options how will you address mineral deposits in the boiler? It appears that you are using a coils system so the buildup would be inside the tubes.
Didnt telsa have a torque converter to go with these?
neat but how will it react with the restive force a generator, it doesn't seem to have a lot of torque value seeing as you were able to stop it by hand great experiment btw
you can capture the used steam and put it through 1 or more additional stages to increase the efficiency, you can also install a heat differential engine to use the waste heat the turbine unit is absorbing.
Сколько набрали оборотов двигателя турбины????????
Wow! Superman can jam a 1kW turbine with bare hands.
a motorcycle stator setup might make more sense than a car alternator for this turbine, less moving mass and you could pretty easily retro something from the multitudes of salvage bikes out there.
Greetings. I wasn't able to fully instrument this turbine to get good numbers under the high drive power of the steam boiler. I was able to get data using a string, weight (mass) and air compressor. The turbine in that set up produced about 150 watts. This was without the steam. The torque was around 0.10 pounds and rpm around 25,000 rpm which works out to around 120 watts for a typical run with around 180 being the best run I could manage using the air compressor.
The steam boiler had a hugely larger amount of power available. At least 10 times the power of the air compressor air. I added the brake rotor to act as a fan to dissipate the rotor energy and even so it nearly flew apart. The 1 kW power output is an estimate. But the steam boiler was producing 20 kW steam output. That was easy to measure based on water flow rate, steam pressure, and steam temperature.
This all means that my best guess is that the turbine was producing around 1 kilowatt of shaft power, all of it going into blowing air around and making bearing noise. But that means that with air bearings and a high frequency PM alternator, the turbine should generate around a kilowatt of net power under those conditions.
This is of course still pathetic............20 kW of steam to generate 1 kW of electrical power. It's an experiment with a tesla turbine. My goal was to build a higher efficiency turbine for home power generation but funding didn't materialize, so this is what I was able to do. See the nearly silent turbine prototype as well.

Thanks for the sharing the data. Reading some of the comments below by people who assume "facts" that are not facts I could only imagine what Tesla went through when this invention threatened the turbine & reciprocating manufactures of his time. I have read all of Tesla's patents and all the other reported statements he made to the press and did not find anything on turbine geometry like different diameters, numbers of discs, etc, as they relate to a desired amount of power or torque for a given RPM. I read from him "of a suitable diameter" and such statements. Problem is that he states the turbine can built by anyone with access to a metal shop - and he is right. Other statements he makes such as working with compound turbines lets me know he did not broadly publish everything he knew. So,I have a few questions if you don't mind:
1. Did all 20 kW of the boiler go into the turbine? I thought I heard you say in the video that you were holding back the steam so as not to damage the turbine.
2. What if you insulated the steam lines and the turbine casing? Without any other modifications how much more power could be realized at the shaft?
3. Using the same boiler and increasing the size of the turbine to say 18 or 21 inch discs and insulating the steam lines & casing would you achieve higher power output and lower RPM? How much more power at what RPM? From the video I could see a lot of uncaptured steam from the exhaust.
I realize that the answer to #3 may well be the result of more work/funding you also spoke of. On that subject, how much funding and time would it take?
Very nice demo.. Recycling the water would also save. A simple screening were the steam would impinge, might have to be large, 3'x3' or so.. Just a thought, every time I see something I want to try it out.. LOL
+woodfirepower You should have vent holes in the front and back of the casing. I would do a test run with an exit hole/pressure the other direction. Make sure everything is balanced for the operational speed. I think you need to make the whole thing about twice as big all around, you never achieve a balance between the interta of the steam, and the RPM, you should be shooting for a turbine that runs into the 80k+ range. You could make a lot of energy out of that with a transmission and a generator.
🔥🔥🔥
Work is force x distance in a linear situation, which is torque x angle subtended, in rotational systems. Power is force x speed, or torque x rotational speed. A puny amount of torque, times a high rotational speed, amounts to a lot of power. It would appear to me that the high rotational speed is certainly present here. Furthermore, the torque is probably higher at the high speed, because the steam had been turned down to get the slower speed that was stopped by hand. Lots of steam later.
Is that 1kW in theory; why is it not hooked up to the generator and don't it take a lot of energy to produce the steam???
Because it has zero torque and under load it would stop. he literally stopped it with his hand at one point. this is the equivalent to a kid blowing compressed air at a fan and calling it a turbine. hes not wrong but he is an asshole
In a closed loop vacuum system, water boils at 30c and returns to liquid at 29c you just need a condenser and a an electrical generator with low impedance and this guy could have a steam electrical power plant for everything he needs running off the heat from the sun or his home fireplace in winter.
I've driven forklifts for years and was wondering if a small hydraulic pump forcing hydr. oil around a cylinder in each wheel the possibility of powering a car that could do standard road speeds of current gas driven cars?
interesting. are the pumps run electrically?
1kw of noise...
🤣
Yes, you can stop 1kW with your fingers. Power results from torque times speed. So a small torque that fingers can stop, combined with high rpm, makes 1kW of power. Notice that it took me a while to slow it down with my gloves.........fingers got hot from friction.
rt
Wow that is a great turbine. I have built about ten small tesla turbines but had no access to a machine shop.
That plume of vapor and rain of condensed steam is an obvious sign of power. Have you considered piping the exhaust steam through copper tubes and pre heating your boilers input water? if so how did it work? if not ...Why not?
Did you just stop that thing with your hand?
How is it supposed to turn a generator if it has so little torque?
this would run so much better on ceramic bearings and if it was fully balanced. good job!
There are tons of Telsa Turbine links all over youtube, and every one of them just show a hose coming in from "somewhere off camera".
That hose is attached to a pressurized water or steam supply that is generated by a POWER SOURCE conveniently left out of the video.
Newsflash: It takes POWER to generate either pressure or steam.
how long does the unit last? what is the cost of the set up? and where to purchase?
efficiency isn't great, BUT to be fair, the steam could be used for heat, as it condenses you could feed it back into the furnace or collect it as drinking water (it's been boiled, so it's clean) and the heat from the furnace could give you hot water and heating.
Hey bud listen, sun may not shine at night, but if you're willing to concentrate it onto some stone or other dense material, you can contain it effectively to keep making steam all night long.
It's only a matter of how much polishing you got to do to get those aluminum mirrors working efficiently...
so what does this vid have to do with 1kw electric generation??????
how could this power a generator? The steam seems to slip right through when a load is applied to it as you demonstrated when you slowed it down with your gloved hand.
Maxwell Jaxwell Lightweight magnets mounted to the brake disc. Then an assembly of small generator coils with light magnets behind them put in proximity. You don't need high torque to produce high voltage when you have speed like that. Mount a 12in disk on it with 1in magnets. That's about 40 magnets. With coils that produce 3 volts at .5 amps you could keep it at low torque, and still be putting out an ac current at about 27 kHz. With the right circuits you could drop that down to 60 Hz at 450 volts/0.5 amps. Bring that down to 110 volts, and up to 2 amps and you could run most household energy efficient appliances. It's all a matter of turning a lot of weak power into a little bit of strong power... And you could always use the exhaust to run another turbine. It would be weaker, but would still contribute. I could go into more detail, but I'm not trying to write a novel here. Hope this helped.
That's more than enough for a TV, computer, or other low usage device. Maybe not a fridge, or microwave, but like I said, the exhaust could power another generator. And one boiler could power multiple setups at once. I understand one of these isn't enough to power an average power hog modern home, but it is viable as an energy source.
If you have the right tools already, and an old hard drive, it's not really that expensive. And if you're talking about fuel, you could always replace the wood fired boiler with a passive solar one, made with a fresnel lens from an old RPS TV(so many for free on craigslist), or at least supplement it with one for daytime use. Things get a lot cheaper when you use a little bit of ingenuity, and whatever free resources you can muster.
steven spall the magnets and coils create resistance. You seem to think that reducing the weight of the magnets and coils will matter. It won't.If the magnets and coils are so small that they would not generate resistance then you would not generate much electricity. This is why those windmills in wind farms are so big. The very large blades of the windmill create a lot of torque. Like a lever, the longer the blades are the more torque you haveThis device generates almost ZERO torque.
PS I would cage the rotor for sure as that will be failure point first, a school suggested that that has a couple of these. Disks will break free of shaft before case busts.
The bottom line is this..how much does the setup cost to operate per watt in terms of heating fuel?
try placing a pressure regulator on it before it goes to turbine place divider inside mechanism and drill hole and tip to recycle water back to origin to to be reused if done right you should reduce the amount half to refill tank of water... it would be continuous as far as torque goes should improve if the systems is sealed but would recommend a pressure valve also This is just my opinion I like it and i'm trying to find most efficient way of producing energy I want to be 100% off grid one day
So is the idea to turn the outside bicycle brake plate in to a A/C generator by engineering magnets in to the plate and positioning brushes around that plate to generate power rather then attaching a clunky generator motor to the shaft.?/ If so I like it the A/C plates can be multiplied and it would seam there would be less resistance. you could expand or retract the size of the turbine engine to your specific need of power.
Probably will have to say this a hundred times.....power is torque times speed. So small torque times high speed equals larger power produced. You put a low torque alternator on the shaft that can handle the high rpm, and you can get good power. Again, that one was probably generating around 500W shaft power. but the rotor can be dramatically improved, increasing the torque and speed capability both.
Just takes time and money to build next versions.

I am planning a closed circuit solar convection heater system, where the liquid would be recirculated, vapor collected & fed back to a small holding tank. I plan to start with water, but plan to upgrade to liquid mercury in the future. I plan to turn a comercial 5KW generator with it. The only literature I found using mercury in Russian but it does mention the turbine blades may become unbalanced because mercury is so much more dense than water. One report also mentions that "some gold appeared to coat the turbine blades". I am sure this is a mistranslation otherwise everyone would catch on this real fast. I suspect it is some kind of golden color that is produced as a reaction between mercury & whatever the material the turbine blades are made of. Any comments / words of advice? I am a scientist & a physician, I fully understand the dangers of working with liquid mercury, mercury vapor etc. What I need is more mechanical advice. Thanks in advance. Tony from sunny & hellish hot Arizona.
It could probably turn a proper size generator. It wouldnt have acceleration like this probably but I believe that it could reach high rpms.
It would be real fun to have your own powerplant at home.
Could you run your steam to a condenser.
would it work with water instead of vapor?
who made the turbine and how do I get one
you should build a cover and holding tank to catch the waist steam. i really do need one can i buy one please? thanks
I think you mean condenser. A large steel plate with cold water on the opposite side would condense most of it. Don't want to restrict steam outflow much.
What ever happened to the Mazda Rotary Engine ?, it was VERY Dependable, and with only 3 moving parts.
look at all that heat thats going to waste .. you could drive a stirling engine with that and heat your house with the energy thats left over
Graham Brechin cogeneration boi!!!
You can use that steam to irrigate a small farm or garden... or condense and recycle inside an enclosed container, which should also dampen the noise.
have you saved money on electric bill?
He stopped it with his hand. How much load does it take to spin a generator?
How much per kilowatt, with varying fuel, and what is the estimated lifespan of this unit, which would include a maintenance schedule, because no machine can ever operate under any conditions without periodic care.
Where is your alternator at?
With a heavier flywheel would it produce enough torque to power a 240v generator?
no
if you could channel the steam you could use that to power a piston set up in order to extract more power.
What if you connected the teslajet to this Cavitation Heater - Overunity
im interested in making a steam powered car, have you looked at robert greens steam engine ?
Ok, sooo it produces around 1kw of energy, I just wonder how much you need to power that compression less thing.. just wandering...
wouldn't a cheap 1/2 air impact gun, or cutoff tool have the same result, being driven with steam?
hope it has good bearing
Asylumescapee69.............
What you say sounds correct. I too thought one could do something like you suggest. But if you do the math on energy storage, you'll find it really doesn't work that way. the one path that can perhaps work is to capture sunlight in water at a lower temp, then run a Rankine cycle using "Freon" or other lower temp boiling fluid, boiling it at warm to hot water temps. A kilowatt hour is a lot of energy and homes tend to use 24 of them per day or more (in US)
