JEREMIAH FERWERDA - TESLA TURBINE POWERPLANT -
Last year's presentation showcased a 3-inch diameter Tesla Turbine operating in the cryophorus mode. In this mode, a hot and cold tank under vacuum with a turbine in the middle can generate high-speed rotation, capable of producing electricity.
This year, you will see a production-ready prototype of a 6-inch diameter Tesla Turbine, also operating in the cryophorus mode. It has already been tested without an electrical load at over 42,000 RPM, which is faster than Mach 1 in terms of peripheral speed.
As of now, this turbine is still undergoing refinement and will be ready for further demonstrations at the conference in July. These demonstrations will include powering various loads. The ultimate goal is to develop this technology into a viable power plant.
Jeremiah Ferwerda, an innovator, experimenter, discoverer, and inventor, is currently refining Nikola Tesla’s beloved invention, the Tesla Turbine. He staunchly rejects the notion that there's no way to harness an unlimited quantity of energy from our surroundings. You can learn more about his work at myteslapower.com/.
I live in the same area you do. It’s awesome there’s people out here learning and bettering themselves rather than wasting their time worrying about things that don’t matter. Keep up the good work.
Yeah, the world is full of people who are not focused on real issues.
Hi ! do you use sealed bearings to keep the vacum in all the system ?
i've missed your videos. Glad to see you posting again.
Thanks! More to come, but if you ever want to see progress without waiting so long you could always join my patreon, I update around 4x per week usually. I will work hard to make more UA-cam updates though.
Maybe you could use an a separate heat pump system to recirculate the the energy entering the cold tank, to collect data to integrate the recirculation system without external input. Insulate the outlet to keep it cold, I calculated with a mass flow rate of 0.038 kg/s (2 inch inlet 30 m/s) 10% conversation to work could be near a kilowatt if the hot tank is 70 degrees F. I may be wrong but i don’t have the resources to prototype my designs so maybe this could help! Ive been working a lot on how to integrate evaporation into the turbine to sort of prevent energy from being exhausted.
i`m impresed buy your work. And i`m glad you are still active.
Thanks! Sorry for the late response.
@@iEnergySupply i`m impresed you replied at all :) Thanks
Also welcome back please keep posting.
Very soon!
good to see yall still at it. can't wait for more.
Ty!
I Love What You do Doing And the pasión that you have!
Thanks!
Wow! Turbine looks amazing!
Thank you!
What are your plans to recirculate water from the cold tank back into the hot tank without having pressure/water back flow so the turbine can run continuously?
Looking much more polished, well done
Thanks! Yeah it has some upgrades haha.
So happy to see new updates from you!
Is this a single stage TT? Did you decide to shelve multi staged turbine design?
Thanks!! It's single stage, ill be testing an additional stage soon with the generators!
Sooo glad to see you guys are still at it!!
Thank you! I am are working hard still! I'm making great progress!
Awesome project, have you looked into the "Hydrosonic Pump"? Your turbine reminded me of one, they are basically a housing like yours containing a wide spinning disc that has holes bored into it's circumference that you spin with a motor. What happens is you supply water on one side and the spinning rotor inside with it's cavities cause super cavitation of the water which causes it to go to superheated dry steam phase. Supposedly the efficiency can go over 100% by a small degree
Well it would be amazing to couple that with the turbine if it really did draw energy from and unknown phananom.
Its not phantom, its just cavitation
Hi Jeremiah, thanks for sharing your videos! Would it be possible to place a weight scale under each tank to measure the water mass transfer rate from the hot tank to the cold tank? It would be useful to know how much heat (BTU/hr) is needed to produce the output power (kWh), I.e. 1) lbs/hr of water evaporated 2) BTUs/hr added to the hot tank 3) Temperature of the hot tank 3) kWh of generator 4) temperature of the cold tank. Seems like a nice way to gather excess solar energy would be to heat water in an electric water heater and have the heat available to run the Tesla turbine as needed.
That's the plan. At the moment, we will be heating the boiler with a heating element so that we can calculate watts in and watts out. We won't be able to measure the weight because everything is fixed to the same platform now. The thermal mass is also very heavy and wouldn't be practical to try to measure the weight. I am working on making the system self regulate so I don't have to turn valves. It can be used exactly as you suggested.
Very excited to see your turbine back up & running. What do you have planned next?
Looks to be running very smooth & stable.
Thanks! I plan on running with a slightly higher temperature to get more viscosity, the titanium rotor is finished and there generator coils are wound. I will be testing in a week or so before the conference, then ill demonstrate the turbine at the conference and launch pre-orders some time after that.
@@iEnergySupply nice man! Love titanium. what kind of metal rotor was on this test?
You'll do great at the conference.
@@iEnergySupply Hi Jeremiah are we able to buy this turbine? I would buy this turbine if I know all parameters of electricity production. Are you going to do videos in the future as advertisements for finished products or this is not still finished?
@@RajGiandeep this test was fr4 fiberglass haha. Good stuff but I was worried to build another one an then worry about temperature when testing the upper end of the spectrum.
@@stefanlicanin9485 It is the production turbine, Just been perfecting it to get it ready for sale. Shouldn't be too much longer.
Very cool demonstration! Any idea what the overall efficiency of the turbine is?
Good question
Cool, already thought the whole thing died. Keep it up and running. Awesome
Won't give up. Had some hard times but pulled through 🙂
Great to see a new video! Love the work you guys do! Is this a single stage design?
Yes it's a single stage design but ill be testing multi stages in the future.
Evaporative cooling integrated with or at the outlet may boost condensation rates allowing the cycle to accelerate as the phase change accelerates in a feedback loop.
We are now using a radiator, and we may use a mist before the fan.
Awesome vid! I have a 3gal vacuum chamber where I cook vacuum-fried chips from -840 millibar heated by a 2kW induction cooker. Vapor pressure moves the evaporated vegetable water to an evacuated 40lb propane tank as a cheap room temperature cryophorus condenser with 1/4" fittings. It can just keep up with 3/4 lb of vegetables with a starting temperature of 280F and a box fan pointed at the tank from 3ft away. Have to thank you for the idea when you first published it a while back. If I wanted a more portable system I'd probably downsize to a heat exchanger and small buffer tank.
Have you spoken to Lindemann at all lately? Has he given any impressions on your progress of late? That guy's an inspiration to us all.
That's really awesome that you used the idea for part of your system. It would be cool if we could recover some electricity at the same time. Peter has been visiting regularly and he is impresses.
@@iEnergySupply that's so cool, you're in a really good circle. Yeah I want to make a high cop or regenerative thermodynamic system. That's the dream thanks to influencers like yourself and Peter
Awesome! Been a while! Was the second segment testing with an unloaded motor attached?
Yeah Unloaded generator/motor. I used it to get the turbine up to speed before using gas, this prevents the condenser from instantly heating up due to the lack of back pressure produced by the turbine at low rpm.
Great stuff!!!
Thanks!
@@iEnergySupply That’s just the turbine? No pump?
It sounds great, I think bigger is better. Nice build More soon i hope. Thanks bud!!
@@mtttony yeah no pump
@@mtttony it will sound even better now that I have fixed the shaft.
Hey Jeriniah How are things I noticed the absence of new video's is everything alright?
Congratulations! Well done.
Thanks, cheers!
Thats pretty awesome i can already imagine some applications for mounting this turbine on a bubbler coming off a motor something like paul pantones geet generator the air inflow comes from the top of the bubbler as the engine runs thus opening up the door to running a generator off from hho while retaining the generators outlets and energy and this is just one 😀
Cool, I can't wait to come see it in a week or two when I'm done with this job.
Long time no talk, hope you’re well, you’re my hero, keep going!
Great to see development, some instrumentation and data logging would probably answer a lot of questions
Best is 1800 to 2000 rmp , you have the best rendement power around 80%.
To +5000 rmp you have only 50%.
This is awesome! Super glad to see your progress. I’m a student also working on a modified turbine, would love to be able to ask you for some time for feedback on our modifications! If that is of your interest!
Will you publish your work on youtube?
@@iEnergySupply I don't know because we're not sure how we want to approach it. Do you recommend it? I'm curious to know what your thoughts are
@@Danieljinchan I'm curious what happens is all.
Looking good brother! Looks like you have some very beautiful machine parts. Wonderful to see you happy and healthy. What applications do you have in mind for this setup? Just scientific inquiry towards Tesla's efficiencies? tests of heat and preasure?
Keep up the great work and don't be a stranger. ✌️❤
Applications will be solar thermal and Wood stove electricity. Just waiting for some more time to post on youtube. I have been posting on patron because I don't have to edit videos for good algorithm results. I will be working soon to make some youtube updates though.
Great test .
Thanks 🙂
Oh this is going to be AWESOME
Looks like you have stepped up your game,good job on all your success
Tesla would be proud
Thanks :)
How will the produce net energy?
No data loggers?
Fascinating concept .... keep at it.
not yet, we have them ready but are taking it one step at a time.
@@iEnergySupply I ask because there was an awful lot of questions of what the system was doing. I don't know how you proceed when you don't note, or log, the test data to know what to test or change in the future. I can't imagine it requiring many IO - pressures, temperatures, acoustic, thermal imaging, and a small home NAS. I love your references to Tesla, and your work. Cheers
@truegret7778 To avoid setting everything up Before i'm ready and taking it down I like to see how things are running. For example I ran the fiber glass roader two forty Four thousand r p m and One of the disks exploded. If I had everything set up then I would be doing a lot more work because I had to take everything apart. Now we have the titanium rotor, and we will do some watt testing at different temperatures. When I'm satisfied that nothing will go wrong with much more testing. I will put all the analytical equipment up.
Looks awesome fair play sorry if i sound stupid is it steam moving from one tank to the other ? ... I always wondered about converting a old gas bottle to a steam boiler to make something i can charge batteries with ...
Thanks, glad you like it! Yes, you're on the right track. It's a cryophorous system where all the air is evacuated. On the left (the hot side), the pressure is higher because the water vapor above the water is at a higher pressure than on the right (the cold side). The higher temperature on the left creates a higher pressure, and since pressure flows from high to low, it boils on the left and condenses on the right. This movement of gas through the system spins the turbine.
However, I want to stress the importance of safety if you're thinking about building something similar, like converting a gas bottle into a steam boiler. Water under pressure can build up to dangerous levels, potentially causing an explosion if not handled properly. Here are a few key precautions:
Make sure your tank is made of metal that can handle high pressure, and know the pressure limitations at different temperatures.
Always use a pressure relief valve to prevent excessive pressure buildup and avoid steam jet injuries.
Periodically test the pressure capacity of the tank, as corrosion or rust can weaken it over time. It’s a good idea to fill the tank with water and test it at a pressure higher than your relief valve setting to ensure safety.
Stay safe and happy building!
@@iEnergySupply Thanks very much for your advice ..amazing work .... Im just wondering if something like this would behave differently if using different types of gas not that i would want to do it as im sure that would be dangerous ... this being a Tesla disk turbine i also wonder if using a Tesla valve with it would be something he might have done perhaps even created for ... really I think its amazing that you mad that turbine and set up its true engineering and innovation .. wonder if you could also link it to a cavitation pump i saw one operating at a fire station it made steam and fed the steam back in while the excess heated the water the whole thing was very efficient reminds me of this havnt heard much about them since it was on a program called tomorrows world in the 90's ... great work anyway sorry for the waffle haha all the best
@@350pauli Thanks for your kind words! You're absolutely right that using different types of gases would change the behavior of the system, and you're also correct in thinking it could be dangerous-different gases have different properties like flammability, pressure limits, and thermal conductivity. Sticking with safer setups is always a good call!
As for the Tesla valve, that's a great idea! While I haven't incorporated one yet, it's definitely something that could enhance flow control in a setup like this. The Tesla disk turbine is highly versatile, and pairing it with a Tesla valve could be an exciting area for experimentation.
Linking it to a cavitation pump is another fascinating thought! Those systems are known for their efficiency and ability to generate steam in innovative ways. The idea of feeding steam back into the system to maximize efficiency is similar to what I'm working on, and integrating that concept with a Tesla turbine could lead to some really interesting results.
No worries about the waffle-it’s great to have these discussions! Thanks again for the support and ideas. The only way to know is to do the experiments and see what happens. All the best!
This is so awesome guys!!!!!
for fun, check my spiral impeller (water wheel) which is kinda roughly same, when ducted and rim-in flow (would need to be ducted to center-out flow), glhf
sounds like jet engine spooling, start-up
Really neat, I had some similar designs In the past, I tested with compressed air with great results. I just ended up moving to Tesla's design because I was more confident it would be more efficient.
@@iEnergySupply surely works fine for you
@@iEnergySupply I have also a version that has both the discs and the spiral, as support
thank you!
Hmm I wonder what Tesla would say about the vibrations coming off that engine. And I wonder if he could have found a way to harness the vibrations.
Making them disappear helped haha. Now the rotor is perfectly balanced :)
@@iEnergySupply That being said about the baring. I wonder if Tesla's baring will ever get it's due. Or ever truly figured out.
And please, what are you trying to get at? For example, spin a Tesla turbine at top speed and then generate electricity? Which will, for example, cool or heat the pressure tank left/right?
Watch the past videos. There are expirations in the videos and responses to the comments as well
@@UnhumanNewman I've watched all his videos, but I don't quite understand what the goal is :( Maybe you can tell me please? :)
That would produce very efficient air condition or heat pumping. We will demonstrate that in the future, but for now we are going to use steam to produce electricity, this was only the first couple tests. More to come.
@ have you seen this video? ua-cam.com/video/2pGxVvSizoE/v-deo.html
@@iEnergySupply It's been a long time, but I'll check it again. Thanks for the reply :) I love watching these type of videos :)
So cool.
Cheers!
Is there anywhere description of the system you are testing?
Looking good! What kind of bearings did you used, ceramics?
Ceramic balls and ss 440 races. Radial contact.
@@iEnergySupply Thanks Jeremiah 🙂
I also remembered a movie from you a long time ago, where you run your turbine made from acrylic on "cold steam" and the water vapor that came out from the exhaust was very cold/frozen. So the vacuum was maintained. And in theory the cold tank stayed cold. Was this really the case?, because that seems optimal and very efficient..
Best regards,
Mark
When all the liquid in the hot side evaporates away from going thru as a steam, then recondenses in the cold side, do you have another connection for returning the cold water back to the warm tank?
Or do you refill the hot and just empty the cold once it's full?
Does that make any sense Jeremiah, you know what I'm asking Right
Or does it just start draining out of the cold side immediately as it starts to fill up
It gets pumped back into the hot side to get re heated by the thermal reservoir.
КПД какой?
Hi j what if you add steam ejector to get the water back from condenser to the boiler tank
this would be a good idea in the open system ill be experimenting with soon.
Jeremiah any guestimation time to having one for sale ?
They will be on sale to the Patreons first, but probably 6 months after that. We are almost done building the refined production turbine that will be available for pre-orders.
I’d love to see valve and gas powered, like you made a couple of videos about ages back
Our next project will be gas powered.
@@iEnergySupply awesome. Good luck with it. I am trying to remember but I think you had a spark plug and the timing seemed odd. My feeling is that the valve itself creates the timing and that once up to temperature the spark should be turned off because its now self igniting and finds it's own rhythm. Then the more gasoline you add, the faster it goes. Maybe the amount of segments within the valve needs to be greater. There will certainly be a sweet spot. Note that within the newspaper interviews, Tesla sad 'gas powered'. I assumed this to be propane or town gas initially but now I reckon, gasoline. Dripping in a wet fuel as opposed to a gas will likely behave differently.
So your ring got hot how? Do you have copper winding inside?
I've been working on creating a vacuum system with threaded pipe joints. Tried many of the sealant compounds I can easily get from hardware stores but I'm still left with leaks. Do you have any suggestions how I can get a leak free system.
are you using galvanized or iron pipes?
@@iEnergySupply Galvanized
is there a substantial difference between the two in vacuum applications
What is the volume of flow and the pressure differential across the turbine?
we will be testing it soon
I can provide your system with an unending supply of cold steam in any volume required. @@iEnergySupply
Did you machine this turbine or did you buy it? I want one, where could I buy one?
I designed it and machined some of the parts. I won't be doing any machining when we go into production which is happening within a couple months. Our patrons will get the opportunity pre order. If you would like to join, it's patreon.com/ienergysupply
Nice. I wish I could be doing something like this, being a pioneer and pushing the limits.
Join my patreon and be a part of the pioneering maybe? The support would help.
did you weld the fitting onto the side of the propane tank?
I had it welded yeah.
@@iEnergySupply I was gonna say be careful cause those tanks are made as cheap as possible and not designed to have fittings on the sides, maybe they're ok.
Brills, watch your backs 👍🏻
At a vacuum around half atmospheric water boils at 80 degrees. You could use the ground as your cold sink at 55. Also if you had your cold sink above your heat sink you could use the density of water to push it into the the heat sink perhaps thru a tesla valve to help prevent flow in the wrong direction
This would allow you to keep a cold sink without adding mechanical work and potentially allow for a closed loop circuit that uses a heat sink say (fire) as your pump also reducing the need for mechanical pumps
You could also create the system/pull your vacuum whilst it is full by using the temp of the water as your guide. By filling it with 80 degree water once it begins boiling you know you have the correct vacuum. U could also create a stronger vacuum by using colder water then the temp you want it to boil so if you want it to boil at 60 degrees so you can still use the ground as your heat sink but you want to add less energy for phase change
Will you break the conventional understanding of the second law and proove tesla right? Are you going to proove we can convert uniform heat into another type of energy?
Can the cryophorous sustain itself till it extracts more joules than we would need to cool the cold tank?
How you are able to maintain the vacuum in turbine means i want to ask was there not any leakage of vacuum at the bearings of turbine?
You have to supply energy to your rig to evacuate the system. You have to supply more energy to heat your hot tank, and yet more energy to cool your cold tank. Are you implying that you get more energy out of your turbine than you supply? Because if you are, then you are touting an over-unity, perpetual motion device. If not, then what's the point?
this exactly. they just simply haven't done the math to show that this is a waste of time. they keep marching further and further down the path of making the turbine better/stronger/more efficient by adjusting all of the systems in front of and behind the turbine. then they run the experiment and say "look how much free energy this turbine makes, all it's doing is letting water boil naturally as it moves from one tank to another." but they are completely ignoring how much power it took to create that large of a vacuum, how much power it took to cool one tank and heat the other. a very simple meter on the vacuum pump, heater, and chiller that made the ice will show that it took WAY more energy to set the experiment up than this turbine will ever make. this is literally just a scam to get money through patreon.
ive gone deep into the rabit hole and have even started working on my own turbine. i worry about the scam aspect and cant wait to make my own tests.
we have turbines now that are better but my main focus is teslas turbine working at cooler temps which opens up many different possibilitites for energy harvesting. that would be my point.
Is the vibration caused by fluid pumping through said orifices or is it out of balance?
out of balance, but it's fixed now.
So how do you keep the cold tank cold for continuous power generation?
Bury it underground
God damn do I want to combine this with a giant sand battery for heat storage and holy cow we've got an invention
If the goal is power generation why not get rid of the moving parts ? This is supposed to run all the time ?
What type of bearing is that?
radial contact bearings.
anazing amazing stuff
Hi, could you please consider trying a closed system with a tesla valve attached to the input and output of a tesla turbine. Apply heat to the valve (or cool it) to create a flow and a temperature difference between the outflow of the valve and the inflow. Maybe add a cooler/ heat exchange in there if needed. Might need to be at pressure or at vacuum, leave that up to you. Liquid or gas dont know. But in short generate a flow pushing one continuous direction adding to it by heat (or sucking it around by cooling) the valve. Might need to spin the turbine to start it. All a little Stirling engine esk.
Experiments like that are on the way. I recently made a giant tesla valve and I am making more for different experiments.
Would enough excess pressure be created in cold tank that maybe could be piped back into hot side?
It might be momentarily till it equalized maybe..
So what is it all about?? Can it run a house electric witout battery? Hop we can see the result of what is the purpse of the xpiremnt...god bless
How long will the test turbine run at this power of 400 watts using 5 l of boiling water and 5 kg of ice? this on the previous 3-inch turbine model.
👍🏻 very cool
So the point of this is to see how much your motor can withstand or?
Hy Jeremiah, great work! This might be a stupid question, but I’m still wrapping my head around the vacuum aspect, could you link the two tanks, so once the water is condensed it would flow back into the warm tank without effecting the vacuum in each tank
Yeah but you want to use a pump and a check valve
Tesla valve ftw!
Maybe with gravity and an airlock sort of system
Disappointing lack of metrology for such an invesment of time and effort .
How much energy is going into heating up that turbine housing from that phenomenon that heated up the ring ?
Why do so many people think this is supposed to be free energy??
I know you have to show that this works on a great scale. but given all your knowledge.... you don't think it would be better to do something smaller with a vacuum and charge 12v batteries at a constant rate. Said device could also be solar.
sorry. I don't want to detract from everything you've done. What you have done has inspired me. And I want to tell you the thoughts it generates in me.
Also... I saw tests with larger systems than you were... what situation are you in now?
thank you! congratulations
well your absolutely right, and that would be an easy way to the means, but I want the house to be powered and we are there now. Stay tuned my friend!
The applications are endless dont stop until theyre in every hardware store
I'm not a rocket scientist and I'm surely not no one to tell someone smart like you what to do, but wouldn't it make more sense to use a radiator and a condenser coil?
I'm just saying if the goal is cool. One side and heat the other. That can be done really easy through a condenser call
That's exactly what I am doing. I will have updates for youtube eventually but for now they are on my patron.
Howsabout a peltier array between the two tank, wonder where it would equalize between the two, but you SHOULD have a reasonable differential between the two, might reduce the thermal loss in later testing, might be useful in cooling the turbine as well. Great job all.
Having a cooler cold tank will helpful for sure, and we will be testing much higher temperatures soon.
It's not just a steam turbine it's many things a pump an engine or compressor !!!
What if you add a turbo fan/compressor fan tk the center portion of the Tesla disk turbine?
that thing is moving faster then a bullet do no stand that close. as try tungsten solves the torque issue by adding weight interference but also makes it way more dangerous. try tungsten carbide
I have crashed it on purpose and is very safe.
Bearings?
Ceramic hybrid, ceramic balls ss 440 races, radial contact.
I hope you used the good bearings instead of wheel barrow bearings !!!
High speed ceramic would be best choice as 70,000 RPM is possible an 450° degrees !!!
You know I’ve always wondered if you could make a Tesla turbine with 45degree cones instead of the flat plates. While the flow on the instead is technically all laminar I still am curious if there are edge effects that rob efficiency.
Hyperbolic cones for the plates...
Warren Rice (1991) already smacked that idea down like a redheaded stepchild. "An early idea of improving performance of rotors by composing them of nested cones rather than flat disks has been shown to produce no performance advantages and to introduce structural handicaps..." all the kiddies in the comments playing toy engineers lol
I see what your trying but failing is part of learning. May i suggest a 6 tank setup. Where the vacuum is in the next tank so its a cycle not just a single power stroke🎉
Hey Jeremiah,I'm the guy that suggested Freon on roof pipes and sent you the creative science and research plans free energy I just had an Idea what if the generator part generated heat to put back in the engine and also have you done high rpm generator load test or would that warp the plates more so . Are you using carbon fiber plates in this new turbine?
So what's being proved here? I see the turbine being spun up. Then a feede tank that's at -1atm(so empty)being opened while the turbine spins down.
The good stuff is coming soon. If you want to see it now you can join my patreon. The system produces electricity and runs on heat.
@iEnergySupply hey man I don't want to be a downer, but you've been saying stuff like this for at least what, 5 years now? I've been following your channel since at least 2018, and this is really starting to feel like a continual c**ktease, especially with it having been 8 months since your last video. Maybe post a new video and let people know what the latest is?
Say you were to build a go-kart, ATV, or riding lawn mower with a 12 HP tesla turbine system, what kind of runtime could you get with two hot tanks of the size of the hot tank you have in this video?
@PhillyEaglesFanatic Yeah, sorry.I've been only posting updates on my patron. It takes a lot of time to edit the videos to make them high enough quality so that I don't Mess up the algorithm. It will be more worth posting the videos now because I can show the entire system operating Is in a real world situation. So far, I've achieved what I need to as far as producing power with the heat. but I had to make it self-regulating, so it runs by itself. This way, I don't have to constantly manually turn valves. And it is actually a product that is practical for power generation.
@@iEnergySupply Awesome man! Again, I hope I didn't come across like a jerk...hope all is well!!
@@PhillyEaglesFanatic No worries, I understand and I want to have more videos out soon, just when I demonstrate the self regulating part.
Interesting.
Now if you can just make it reverse cycle once pressure equalizes.
Playing with steam, which I'm sure you have already discovered, every 35 lbs of pressure is equidistant to one horsepower of force.
The power depends on pressure and volume.
If my math is correct, a disk of 6" spinning at 42krpm would result in a centrifugal force of ~300500 g ...
What material are you using for the rotor???
Using fiberglass fr4, It actually failed at 44000 rpm. One disk exploded. Instead of using carbon fiber Or fiberglass, I built a titanium rotor for testing. We will be testing with higher temperatures now because of the increase in viscosity.
That's an impressive g force!!
Question:
Is it plan to have mutlitple same sized turbines in parallel to increase power, or will you be designing a bigger, high mass turbine to get more power from weight?
From my understanding, the real advantage of the Tesla turbine is the small size - efficiency drops at larger sizes, and the efficiency of regular axial turbines in modern steam power plants is already at over 90%. I've been following this experiment for a while, because I love Tesla's ideas, and it's just interesting and good fun to see this replicated. But if you're expecting free power, heh, well, no contraption can harvest more than 100% of the energy potential, and we're already at 90% with modern facilities today, so there aren't any miracles to be had here. I'm sure these guys are smart enough to know that. But it's a fun engineering challenge either way - because it's difficult and others have tried and failed. :-)
@@RasmusSchultz who said anything about free power lol.
Well, you can still get higher mass by using different metal disk.
@@RasmusSchultz Respectfully I have to disagree with the idea that larger sizes lower the efficiency. I am aware of lesics Video that try's to explain why but there was a big mistake in their math. Here is my comment which was blocked on his video. "I just wanted to note a big mistake in the video! The video says the rotor must spin at a very high rpm, maybe 50,000 for a 6” turbine. The speed of a turbine is based on periphery speed not rpm. If a 6” turbine needs to spin 50,000 rpm to be efficient like the video says, that’s a periphery speed of 890.1 Miles per hour. If you want a 3 meter disk to achieve close to 891 miles per hour at the periphery, the rpm required is only 7,253. We have materials that can easily reach that speed." And here is what nikola tesla has to say, and it's important because he even built a 6 foot diameter turbine. "I have found that the quantity of fluid propelled in this manner, is, other conditions being equal, approximately proportionate to the active surface of the runner and to its effective speed. For this reason, the performance of such machines augments at an exceedingly high rate with the increase of their size and speed of revolution."
Ill be testing two turbines in series soon.
The problem with larger diameter turbines is not directly related to efficiency. It's about the force exerted on the blades. The larger the disc is the more centrifugal force is exerted on the outer edges of the blades. Larger diameter turbines must remain at lower rpms to prevent the blades from blowing out. If you had a material strong enough to withstand the extreme force exerted on it you could spin up a larger turbine and still get those high efficiency numbers.
What if you used two with ferrous liquid metal and had them counterclockwise to each other and put a giant crystal in between or some other conductor. Would you get a piezoelectric effect? Or would they create some really strong flux or voltage if they spun super fast in opposite directions?
Just spit balling.
And when you make it bigger and introduce a combusting fuel ?
From vaporized gasoline to natural gas ???
Modern materials were this engines shortcoming .
Wear hardenable stainless an ceramic bearings could easily handle the heat
You could pump to produce electric with a geared drive ...
Heat from cooling jacket would produce hot water or even steam ...
turbomolecular vacuum pumps go through the same rpm and also have a zone when they are loud. above 22 000 RPM they get "silent" - which is really dependant on the ears of the observer. when slowing down, even with ok bearings they do become loud... So, have you looked into turbomolecular pump bearings - ceramic bearings? Agilent has those.
Hi Jeremiah, say you were to build a go-kart, ATV, or riding lawn mower with a 12 HP tesla turbine system, what kind of runtime could you get with two hot tanks of the size of the hot tank you have in this video?
How hot do the individual blades on the turbine get?
Id name it the Teslaphorus
