@@Signmonkey So here we are 2 years later and no data. Anyway, there is so much more power to be captured from that water than you're catching. You guys and your V-belts. Not sure why so many people like to give up horse power to V-belts.
@@selahman1074 Yes that belt. I would go with a serpentine belt if I had no choice but to use a belt. Those V-belts rob a lot of power. Especially as torque increases. The best alternative would be a gear box. Yes they cost more but they last much longer, require less maintenance, and your power output would be greater. V-belt loss can be as much 175watts on a 25amp draw even with proper belt tension. That's a lot on micro hydro systems. Not just due to creeping/slipping but also friction. The absolute best would be direct drive. I'm not sure if that's applicable with an Archimedes as they turn so slow. The alternator would have to be much larger in diameter to be effective at low rpm's for direct drive.
I am Australian but this year was in the UK for 10 weeks and visited Cragside, the country home built by William Armstrong, a 19th century industrial giant, now run by the National Trust This house was the first house in England to have electrical power, generated by his own Archimedes screw just like yours. It powers the whole house, completely off grid, over 240 LED light globes, refrigerators and computers etc. The comments decrying the worth of such an installation obviously do not understand physics in general or gravity in particular!
I was fascinated by this as a kid and remember seeing films where Egyptians watered their fields using the same age old technology, its refreshing to see it hasn't been lost and is still pertinent today. Its what in the U.K. we refer to as low technology but to see modern applications is great to see.
Great project, beautiful turbine ! It would be really useful to others if power produced, flow rate and the screw dimensions were given. From looking at it while running, I guesstimate a power output of 400 watts. Here is how I guesstimated: Generated Power (watts) = electrical (generator cables, convertors etc) efficiency 80%) x turbine efficiency (50%) x water flow rate (0.05 m^3/sec= 50 liters/sec) x total head (2 m = length(4m) x Sine(30deg)) x density of water (1000kg/m^3) x gravitational acceleration (9.8 m/sec^2)) =0.8x 0.5x0.05x2.0x1000x9.8 = 398 watts. Turbine efficiency can be significantly more or less than 50% depending on the details of the design. Water flow rate is the primary uncertainty. I would love to know how close my guess is !
If we knew the flow rate and the height the water falls we could at least get a general idea. These screws aren't very efficient due to drag. Now that I think about it I doubt it even makes a single horsepower.
Actually, in most mountainous areas creeks still keep flowing at least a little when winter comes, it might be less than a third of what it is normally, and a tenth of summer melt flows but it still chooches!
I think this is a GREAT video. I agree with mikhaelis that it would be nice to know how much power you are producing per day or week. And the DIY of how you made your screw and what type of generator you are using on it. For homesteaders this idea is of great importance. I hope you would do a video on the building of it. Thanks.
Beautiful design that can heat up an infrared sauna and the green house too :-) Basically free heating and free light for the home. We can be happy about it !
This is really neat, I have always wanted to build something that does exactly what you have it doing at one of the creeks on my dads farm so this is a really interesting concept to me
Really cool! Nice job--I wanted to do this years ago while living next to an abandoned mill foundation--the spillway was just screaming to be harnessed into a bit of energy.
kwb it produces aprox. 2.5 lbs of screws daily depending on screw type, however metric threads take longer as the screw producer has to turn in metric intervals to produce nessessary voltplunges for the wtf'er.
Congratulations! Nice system and nice video. Good to see something i would like to make for myself. One question. How did you make the screw? In my country already built are not available. Thanks in advance.
Pardon my language Sir! But this is Badass! I'm a free energy seeking individual and if I had property and a creek, I'm definitely doing this. Thanks for the share.
You shouldn't call it free energy, because that means something else. This is just a form of solar power, which is great stuff, but doesn't break any laws of physics. :)
Hi Sign Monkey! I have a question. I was looking through the comments and saw that you made this screw yourself. I was wondering how exactly you did that or what process you used to model/design it and also what material it is made of? I am currently a senior in university and working on a graduation project and would like to implement an Archimedes screw into the design. I am trying to gather information on how to get/build a screw this size. Thanks! Also, awesome video and idea!
How does this Compare with a Micro Hydro charging system in Wattage for the amount of water? I like your idea! I was just wondering the other day how efficient a Archimedes screw would be?
It looks like that stream slopes down a fair bit after the waterfall, what is the total head of the stream across your property? Would you produce more power by building a small dam (4'-6' tall just to create a small settling pool) adding a Coanda screen intake and diverting the stream flow into a penstock down to a Turgo turbine at the lowest point of the stream.
awesome . First one I've seen using a screw . I am curious as to how efficient it is compared to something like an overshot wheel or a nozzle jet powered pelton wheel .
You could see it was running a car alternator, so it not producing massive amounts , and notice how much load was coming off when he unplugged those two things alone give fair estimate of production, well done nice project
Cut him some slack folks. No good deed of presenting a neat power generation idea to the off grid, techie community, will ever go un-punished, without full disclosure. An excellent demonstration in my opinion. It will be interesting to see how it performs over time and yes if you could provide some output information. That would be very interesting to hear. I imagine that grit or small stones may be an issue. Possibly wedging between the screw and casing. Have you had any issues with this?
I suspect it's not as efficient as a pail wheel or some other design. But, it sure is cool. I like the clear plastic top so you could see it in motion. And like other people, we want the speeds and feeds and how did you make it.
it caught me by surprise also to see it being used in reverse, I like the concept and would like to take a little more in depth look at the process and possibilities.
This application can be applied to wave generators with water level riser stacks where air pressure+wave crash momentum raises the water inside to drip down.
That's kinda cool; looks like it could reduce the amount of filtering fiddle-faddle needed with "modern" turbine generators. Just keep the bigger rocks and debris out and your good. It may not be as efficient, but I'm lazy and would rather not go out every other day to clean screens out...
An open aqueduct offering a bigger cross sectional area, would be more efficient than the delivery pipe that you have chosen to use, to feed the turbine, as it would have less friction and less fall required to shift the water to the turbine intake, which means you would have more available head, and could therefore install the screw turbine on a steeper angle, or make it's screw longer, to take advantage of the additional head, which in turn means a better wattage yield.
Increase the head available at the input of the blade, flow rate is ok. You will get more power than that. As power = ρgQHη Where ρ = density η = Efficiency of turbine g = acceleration due to gravity Q = discharge of flow H = net head available at the inlet of turbine Increase H, increase power
That unit looked awfully well made for some cobble-up. Is this a repurposed lift screw rig? If not, how about a vid on how it was made in your home shop?
Would be great to know how much electricity you're producing with it. Also, with the generator unplugged how much effort it takes to stop the screw turning. I reckon it would have a load of torque. Nice video.
This is a pretty amazing construction! What I'm thinking: What the would the difference be if you didn't have that long screw and you just did a small fan/turbine at the end: you would get the same speed, the difference though with your screw is that you have enormous torque and this you can leverage by using a much bigger generator motor for more power.
Making, Cooking, Fixing I’d like to know if having the screw vertical changes the speed and also some means of knowing how long the screw needs to be to produce the required torque for a given rpm, since things like this could work on house down pipes or in lower head environments.
So I see someone else already asked about power output. I see what looks like a regular automotive alternator there... which would mean 13.8 volts and maybe 10-20 amps.. so that thing probably isnt putting out more than 100 or so watts... but 24/7 means good steady energy...
If you spin it in the other direction with a motor or crank it by hand, it will pump water uphill. That's what the Archimedes screw was originally invented for.
It's an amazing thought that a human from 2,500 years ago is still having an impact on our lives, great job utilizing such interesting technology
truth is timeless
For those of us who are a bit more technical, some data on voltage and amperage plus calculated wattage would have been the most interesting part.
Next time
I was JUST about to ask... LOL..

Great workmanship you just see this is built by a craftsman. Keep us posted on any updates to the project.
Might actually be interesting if you post how much it produces.
It "might" be able to run my computer setup. About 1KW or less under load.
If we knew the flow rate and the height the water falls we could at least get a general idea. These screws aren't very efficient due to drag. Now that I think about it I doubt it even makes a single horsepower.

I plan on building a simple one with a video that shows you how to build it.
@@Signmonkey Is the video on How to build it available?
Oh wow!! This is a nice lil set up you have here. You could easily add onto it and generate a nice amount of electricity.
Really cool! Nice job--I wanted to do this years ago while living next to an abandoned mill foundation--the spillway was just screaming to be harnessed into a bit of energy.
Go to it Carl!
I would need to get so many approvals to do this where I live. That thing is cool. Not terribly efficient, but excellent demo.
Brilliant, what a lovely place, thanks for the lesson
Awesome
Great Job
As a pipe fitter I can really appreciate this
Thanks!
Sign Monkey
Now make it go up hill like he did
Or
Did he
🤔🤔🤔
i dont get it, where are the screws collected? how many screws does this generate an hour?
kwb at least they are nice and clean...
Screw you !
kwb it produces aprox. 2.5 lbs of screws daily depending on screw type, however metric threads take longer as the screw producer has to turn in metric intervals to produce nessessary voltplunges for the wtf'er.

Hey there boss I absolutely love what you done I love your video I enjoy science and I look forward to seeing future projects
Awesome. I would have thought some 1 inch walls on the screws blades would help hold onto the water longer increasing the output.

For everyone asking, it produces 1.21 gigawatts! Enough to power 10 million light bulbs or 1 Flux Capacitor.
that’s heavy
Like I’m Back to the Future. 😂👍
🤣🤣🤣
What kind of power do you get off that? Volts and Amps? Well done!
Nowhere did it occur to you to mention how many watts it generated?
How many Amps and at what volts.... likely 12v at between 10 and 40 Amps..
@@bobhoward9016 120 volt, he said when hooked up the drill. nothing about amps though
Hypothetically if the screw was to be upright would it produce more power?
I suspect it's not as efficient as a pail wheel or some other design. But, it sure is cool. I like the clear plastic top so you could see it in motion. And like other people, we want the speeds and feeds and how did you make it.
you left put the most important part which is why the screw? Does it give you an advantage over just a straight fall into a paddle wheel?
Great work, do you have a video for winter scenario?
if you give the screw blade a cup shape would it work better? I was just thinking that if it could hold more water it would have more pushing on it.
Yes, that's what I'm hoping build one day.
Pablo Pérez
IT IS A NICE PROJECT, YOU COULD TELL US THE GENERATION CAPACITY OF THE TURBINE PLEASE?
The screw was conceived as a water-lifter.
The way you are using it, just makes it a curious Impediment to water flow
it caught me by surprise also to see it being used in reverse, I like the concept and would like to take a little more in depth look at the process and possibilities.
Can you put a link or video on how did you build that and where did you bought the spiral blade and what is the best motor for hydroelectric energy.
Hope you told your wife beforehand that you were going to pull the cable out to demo something..nice to see great diy project in action!
What is the max power produced ? How did you make the screw ? Many thanks for the video
There is 30 KWh Archimedes screw generator in a village near me. Paid for by a group of folks who now use this power.
This application can be applied to wave generators with water level riser stacks where air pressure+wave crash momentum raises the water inside to drip down.
TQ Sir GOD bless you family and business
I think that Small Hydropower systems will be the future of energy generation. Another similar system is the Turbolence Hydro.
That's kinda cool; looks like it could reduce the amount of filtering fiddle-faddle needed with "modern" turbine generators. Just keep the bigger rocks and debris out and your good. It may not be as efficient, but I'm lazy and would rather not go out every other day to clean screens out...
Great! The water’s weight pressing continually against the entire length of the screw...much pressure achieved.
That is a great invention that would definitely power the world one day thank you for sharing
I would belt a bigger gear and from there another small gear to triple or quad the output. What do u think?
I wonder if a progressive thread or variable thread screw would work better?
Have thought about that myself, may give it a try sometime
Hi where did you source the auger/screw having a hard time finding one in orlando
An open aqueduct offering a bigger cross sectional area, would be more efficient than the delivery pipe that you have chosen to use, to feed the turbine, as it would have less friction and less fall required to shift the water to the turbine intake, which means you would have more available head, and could therefore install the screw turbine on a steeper angle, or make it's screw longer, to take advantage of the additional head, which in turn means a better wattage yield.
Increase the head available at the input of the blade, flow rate is ok.
You will get more power than that.
As power = ρgQHη
Where
ρ = density
η = Efficiency of turbine
g = acceleration due to gravity
Q = discharge of flow
H = net head available at the inlet of turbine
Increase H, increase power
Very cool! Way to make good use of a small drop!
One can only imagine the torque it delivers.
How much power are you producing with the generator? I love it, by the way.
That unit looked awfully well made for some cobble-up. Is this a repurposed lift screw rig? If not, how about a vid on how it was made in your home shop?
use a motor from a big treadmill..generates more power... but where did you get a screw that size
I used a permanent magnet generator designed for a windmill. I make the screw
presses the button of the drill, the whole creek grinds to a screeching halt
Very nice. Would a flywheel help keep the momentum going and negate the load drop?
"come up with crazy inventions" yet you acknowledged that Archimedes invented this, gj though. glad it works
what's the impact on the wildlife?
How much power does it make? could b watering the crops thro Swales like permaculture farm to in one
Would be great to know how much electricity you're producing with it. Also, with the generator unplugged how much effort it takes to stop the screw turning. I reckon it would have a load of torque. Nice video.
This is a great idea now to convert my old grain auger and give it a try

Great fun, cool vid. We could run that off of any header tank or dam etc too.
Could you theoretically make something like this using opposing ferrite magnets to make it generate? Sans water?
We have 800 cubic water with 10 meter height. How many kilo Watts of energy could produced from it??
1:26 a rare sight of a screw powered drill in the wild
Yeah i guess the person operating the electricity generator could be called an electric screw driver??
How did you make the screw? Was it a purchased item? Looks like a post hole auger, but you'd never get that to turn by water power.
We have 400 cubic water with 3 meter height. We want to generate electicity. How many energy could produced from it??
What if you were to make it a solid tube and a higher angle?
Holy steady cam Batman. Puked before I could see anything
Excellent work sir.
Why is power box under water pipe. Might want to move it away a bit
I would like to purchase only the screws. Is that possible?
your work is quite admirable, thanks.
The screw is beautiful ! How did you build it
Would love to know where they got the screw or did they make it?
very cool! How many watts are you pulling on a day like that? and how many watts do you get on an average low flow day?
So I see someone else already asked about power output. I see what looks like a regular automotive alternator there... which would mean 13.8 volts and maybe 10-20 amps.. so that thing probably isnt putting out more than 100 or so watts... but 24/7 means good steady energy...
What kind of torque does it end up producing? It's extremely intriguing but is it practical?
How much power does that minihydro can generate?
How many watts are you getting out of this?
If you spin it in the other direction with a motor or crank it by hand, it will pump water uphill. That's what the Archimedes screw was originally invented for.
Where do you buy such materials?
How much to construct?
Could you show us how to construct one ?.....love the video! Thanks!
Good on you. I always thought that Archimedes screw was a water lifter.
Isn't the water supposed to be going UP the screw?
Hello Where did you find the Archimedes screw?
Where are you purchasing the yellow plastic screw material.
