1000 Peak Watt Tesla Turbine Unbalanced, Low RPM Test!
HTML-код
- Опубликовано: 6 сен 2024
- We finished balancing the turbine, it sounds soooo quiet in comparison. We will be testing 18000 rpm soon and in addition to that, Ralph has completed the laminar flow nozzles!! Our goal is 3000w continuous output. The entire system will be powered by a 212 degree water battery. More details to come. Thank you Patrons and everyone else who has helped with the project!
We are about to have the entire system set up! Solar heat tubes, water battery, dual stage tesla turbine, power conversion system. I am going to make a diagram to make everything easy to understand and testing without air compressor in a matter of weeks! Cad drawings for our final turbine are also on the way!

iEnergy Supply, you have come a long way since your plastic turbines of the past. Looking forward seeing you take it to the next level.
Ironically I could return to a plastic casing with our new carbon fiber rotor and the low temperature vacuum system but the stainless steel version will be great for combustion, I even have a revolutionary tesla valve that enhances the valvular conduit combustion system a new tesla valve designed by me that has almost 6x more Diodicity and will make the combustion turbine cake. That's a future project. The valves are structures that have a higher pressure drop for the flow in one direction (reverse) than the other (forward). This difference in flow resistance causes a net directional flow rate in the forward direction in oscillating flows.
@@iEnergySupply This seems like excellent progress, I'm hoping you will offer to produce rotor disks for others, carbon fiber items sound like it would take a bit of capital. I've also discovered that there may be an ephemeral creek that runs thru my new property I could run a trompe off of, so I might be interested in buying parts for a tesla turbine of my own design, I would really like to show you my proposed improvements.
Awesome!
Thanks!
This is pretty amazing man, can't wait to see it running on the water battery! I'd be up to helping create any diagrams or presentation animations if there is a need for it.
Right now I could really use some video editing skills, I make tons of content and not enough time to do anything with it.
@@iEnergySupply hit ya up on Facebook, dropped my email in there
Could you send me a friend request on Facebook?
nicely done can't wait to see water battery setup, hey what happened to grav inert's channel it was really good hope he's okay? rest easy friend
He is ok, just had to close down for his investors. I guess his family needed food and living. It's really hard to be an inventor and survive. Thankfully I'm getting support without them.
At least some video about a progress! Keep going! 😁
Will do!
@@iEnergySupply i am watching you like a hawk
So happy to see another upload. Nice test!!
Thank you! Cheers!
Nikola Tesla's spirit may bless you young man !
Thank you!
With this many amps you may want to rewire the coils to crank up the volts, cause it seems load slows down the turbine quite a lot.
You are absolutely right. We will be cranking the volts up to 600 because we got a new charge controller that can handle higher voltage.
@@iEnergySupply Awesome, can't wait to see the results! :D
I am still waiting to see you run it as a vacuum pump. Simply running it in reverse with the discs spaced 0.2mm apart and testing it using a $50 piranie gauge you can increase your sales by 100s of times. You could literally be selling these for $1k+ each if you can pull a vacuum greater than 1x10-5. Every home scientist will buy them.
You shouldn't need more than a 500-800w blcd motor to run it either since that is what Turbo molecular pumps use. Take a big glass jar and set it on a silicon baking sheet and you have a vacuum chamber. Drill 2 holes and stick a hose and gauge in and seal with silicon epoxy. That's it.
Great ideas! We are testing separate units soon, turbine and pump on separate shafts so we can utilize full vacuum before we even start the turbine. We will for sure do the testing with it as just a stand alone pump, propulsion will also be tested.
@@iEnergySupply No, not using the vacuum for power. Use the Turbine TO PUMP a vacuum. You spin it up with the motor and it sucks the air out of the vacuum chamber. It was one of the killer uses suggested by Tesla but as far as I can tell, NOBODY has published any numbers on how high a vacuum can be generated. I have spent months reading every research paper I can find on the topic but there has been no real testing done.
Turbomolecular pumps are complicated and expensive. This is why home scientists are limited to basic vacuum experiments. This would be a Turbo drag style pump like the Gaede or Holweck pumps but using flat discs instead of grooved cylinders.
Someone on Hackaday has tried a small scale model but t was nowhere near big enough to pull a decent vacuum. Your turbines are about the right size and since they are steel work for pulling high vacuum. Around 40-60k RPM you should be able to get down to that pressure. There is less resistance in the vacuum so as long as the tensile strength is good enough it should be fine. TMPs spin up to 100k rpm with 1-2mm blades.
You can actually space the discs more than 0.2 mm apart. You really need to match the Mean free path of Helium at the outlet pressure which is around that but if you have a rotary vacuum pump as a roughing pump you can go as large as 1mm once it is pumped to 1x10-2.
The best design (which can come later) would use multiple stages. A hollow shaft with 6-7 discs press fit onto it then a spacer plate and then another 6-7 discs with a smaller/narrower spacing and an end plate, plus a piece of pipe as the housing for each stage. With 3 or so stages you should be able to pump from a very high vacuum down to atmosphere without a second pump. The hollow shaft will also need to be drilled/slotted and have plugs to guide the air.

@@iEnergySupply the idea of using a vacuum electric motor pump, is not a terrible idea... ie, like you said, once it starts to flow, there is a lot less energy requirement to spin the electric vacuum... until getting the second stage idea to work better etc. , just bleed off some of the electric energy output, to run an electric second stage vacuum pump.. I caught this idea from you a while back when you suggested it... another out there idea, is to have a recovery system, large enough "tank(s), to store all the fluids vapor , after it boils. Or some type of real time condensor gas/liquid. I like the anhydrous amonia idea, but it starts to get more toxic... a pure water system seems like the long term answer...
in addition, a while back, you had it gaining rpms, although slowly, just off of the heat in the rooms atmosphere, after it was spun up... that intrigued me a lot! No supply tank, no recovery tank... this indicates you could just use a hot room of air with some humidity...
Hey guys! Thanks for the load test (and simultaneous camera shots).
What I would like to know is the total NET energy efficiency of the whole system (work in - work out).
Ideally, you could set up a Rasp. Pi (or manual data logging at intervals) with digital sensors, flow meters, and gauges to plot the data and calc the efficiency. Also, log the compressor cycles over time along with a Kil-O-Watt meter to measure total energy input. =]. Cheers!
we have an analytical system we are going to use to test everything to give the numbers needed.
If anyone is looking to build one of these and are looking for bearings, i use seadoo supercharger bearings. Cheap and they work very well. I do oil them though.
What's the purpose of this? Is this just a mechanical test to prove the hardware works? I don't see how this is efficient in this setup? You produced 24watt hours of power in the video, I'd assume it took much more power to compress the air required to run it? I don't get the end goal what application is this useful for are you expecting higher efficiency with steam?
Please see this video to help you understand the true purpose. ruclips.net/video/JvRCB_HhseY/видео.html
Soon...
so soon!
Talk about power to weight ratio.
Wait until we test our new coils in the cold steam system!
I have been very interested in Tesla Turbines and absolutely loving your content. This video is the first that has addressed the issue of torque from what I can tell. It seemed like any time you applied a load (the charger) it started loosing RPM (and thus power output) and it didn't appear to reach an equalibrium point. Will the finished turbine have enough torque to maintain a reasonable load (like 1kw). I am very curious how this would scale to say 20kw for potentially running a small off grid shop.
Hi, I enjoy your you tube clips. A question if I may, as I understand you use a 1 to 3 ratio between motor and pump, do you need to use larger spacers between the pump discs in order to efficiently evacuate the fluid at the exhaust end. Thanks in advance. Cheers John
I think because there is so many extra gaps it will make up for the spacing, but I would love to experiment with the gapping on the pump in the future.
What happened to the combustion engine? I see you switched to compressed air
Compressed air is only to substitute a boiling fluid. Please be patient, I have some awesome stuff coming. The combustion engine is only one of our projects, the main system is almost complete.
Amazing and impressive Jeremiah! - well done!!! 👍
Being a physicist, I am puzzling since some time how to convert the too much heat power generated by a vacuum heat pipe solar boiler into electricity in the summer. Sterling motors and Tesla turbines were my thoughts all the time. I would be interested in graphs that show transfer functions i.e. temperature and/or pressure input vs. W electricity output. My hot side would be around 80 degrees C and the cold side (in the summer) around 20 degrees (when not using an additional compressor / heat pump). How much power could I drag with these numbers using a Tesla turbine?
Best, Marcel
Thank you! We will soon answer all those questions with our new turbine. I've been waiting for this final tesla turbine to sell. it took me a long time to get everything right.
when you say 212 degree water battery, do you mean that you will power the turbine with steam? Will the turbine have problems with the expansion of the discs due to the increased temperature when working with steam instead of air?
Because we are using a working fluid with a lower temperature boiling point, the system will stay cool. the water battery is not in-line with the boiler tubes but is only connected through heat exchanger to boil the ammonia water mixture. Anhydrous ammonia boils at different temperatures based on the concentration of water and ammonia. This allows us to get higher expansion and pressure at lower temperatures.
@@iEnergySupply oh, i didn't know about the ammonia implementation. Nice! good luck guys! I wanted to suggest that since you want to create some vacuum at the end-point of the turbine, why not connecting the output with a tall chimney instead of wasting energy on a vacuum pump? or maybe combine the two!
@@gdlignos the thought is that the Tesla pump in series after a Tesla turbine will provide the necessary vacuum behind the turbine to find.
I'm unsure what happens before the Tesla turbine. Does it not matter that air could leak in from there? Or would the head pressure of the boiling tank prevent air leaking in?
How would the boiling tank be in a strong enough vacuum to allow for cold stream?
This is ignoring the fact that the set up might be a closed cold stream with ammonia set up
Well done, dudes. :)
I still want to know the input energy to work out the efficiency of the whole system though.
Getting useful power out is a big step forward though. Well done. :)
Working on it! Thanks for the compliment :)
Carnot efficiency is about 20% 100 degrees C -> 20 C heat sink. So maybe about 16% for this?
@@N330AA That would be *extremely* unlikely.
Most engineers working on triple digit power ranged (100+ kw) seem to hit an overall cycle efficiency that's about half of what the Carnot numbers are and those are with turbines/compressors averaging an 80% mechanical efficiency.
Thus far I don't believe anyone's produced a Tesla turbine setup that can hit 80% meaning 30%-40% of Carnot would be an achievement. I'd be optimistic if they broke 5% and genuinely excited for breaking 10% overall.
@@Cheebzsta Alright, well i'd be interested to know myself. Seems like increasing the temperature is the best bet to raise efficiency though.
I'm very interested in this thing as i want to create a waste heat recovery system for a boat.
2/3rds of the engine power is wasted out of the exhaust or coolant, and the exhaust is spitting out 500 degrees C so a lot to play around with. Even just a 5% recovery would raise the engine efficiency by 10%.
@@N330AA Oh! Absolutely! I hope you achieve the results you're looking for.
I've bounced around an idea of a diesel generator running on locally produced biodiesel that skips a catalytic converter entirely in favor of venting the exhaust directly into a pulse combustor that powers a Tesla turbine.
Add in a simple gasifier system to provide the 'pilot light' of the system that helps guarantee the full combustion of the exhaust products (which are full of various hydrocarbons & NOx) and you've off to the races.
Could easily imagine a secondary system liquid water engine running on both the cooling heat of the gasifier system as well as the final exhaust heat of the primary engine as well.
I'd love to see a triple system that overcomes the inherent losses in a Tesla turbine (let's assume that 70% is the ideal) by making three separate engine cycles (Brayton -> Rankine -> Malone-style Stirling cycle where a waste-heat recovery cycle low efficiency verison water-based Stirling/inverted Brayton engine powers the first stage pump/compressor for the other cycles).
Use the things the Tesla turbine is good at (cheap durability with multi-phase flow) to overcome what it's bad at (outlet losses) and boom! You got yourself an engine. ;)
I have rather important question. Approximately what pressure would electromotor driven tesla pump produce? This information is important for me so that I can fully understand the power and capability of this technology. It's like a missing piece of the puzzle...
Btw this was very amazing video and I never can wait for more development.
The max amount. You want to have a system where nothing is a bottleneck. You have electromotor max speed, the pump max pressure and the flow of vapor input
@@CharlieSolis Big thanks! all of this can be a valuable information to me
Thanks guys for helping answer questions.
So awesome! If you need cnc machining I'd love to help with this!
I would love to pay my machinist, he is having trouble keeping his business a float. Are you offering your machining, or the machine?
@@iEnergySupply I feel I can relate - machining professionally for an aerospace company has made me decent money but my own CNC in my garage hasn't made me very much money yet.
That said I cannot let go of my mill but I can humbly offer machining if you need it for future projects! I've got 10 years experience in high-end Aerospace Machining and 3 years experience programming for my own garage shop. You can find me on instagram! "c_b_dynamics" is my insta.

Why would one not want to use a Tesla Turbine as a ram air generator for an RV (while driving, using a naca type duct) battery bank? Thank you!
Mantap
Woot!
@@iEnergySupply mantap = amazing
Is the air entering the casing through a nozzle or simply through the pipe seen in the video?
through a nozzle. The nozzle is extremely important.
@@iEnergySupply I can understand. Actually, for a long time, I am thinking about using a blower fitted with a nozzle for such a turbine.
Jeremiah: i was not able to connect to your website. i have no problem connecting with any other website. just to let you know theres a problem
GoDaddy deleted it because our credit card expired, we didn't catch it in time.
Awesome bro, have you found away to over come the drag from the load. If your struggling I can help you out.
I was always under the impression that was normal. For now it's not a problem.
@@iEnergySupply totally normal for a circuit in that situation of course very inefficient and alot of heat and drag.
@@iEnergySupply you have the right idea with the oscillator to power the charge controller however you have wired the oscillator to the controller just like any conventional generator would be. there is another way. Let me just reiterate its not the set up tesla had considered when using this turbine as an oscillator, judging from his patents anyway because of the high frequency nature.
@@EnterTheRealm the generators that are okay with high rpm are the reluctant machines, like the flux switched alternator. Any idea for other likely generators?
@@Dan-gs3kg It's not the generator that is the problem. You can use most generators. In fact the one he built himself in the video is perfect. It's how you use it that is the problem. We have been doing things backwards in a sense. The output of that generator should never be in a closed circuit situation that's why there is drag and heat. What I'm saying is there is another way to connect a load to any generator.
Guys, your website is not working.
Sorry we are working on a way to make a new one, GoDaddy deleted our website because one of our cards expired. Really messed up but after we paid the fee they said, well we deleted everything, but you can renew your website domain name.
what is your disc gap?
the gap is actually too large in this model, it's about 1/16th"
@@iEnergySupply I keep reading the gap for steam should be around 0.015", which gives me the idea of using 0.015" water jet mixing tubes to direct the steam between the discs. I often wonder how much the turbulence from the steam colliding with the edges of the discs would effect efficiency. Really appreciate your videos, my wife got me going on my designs again and your work has further invigorated me.
Water battery?
More details to come. Basically heat energy stored in water.
I want one turbine what's process?
Build one.
We will soon have them for sale, I am nearly satisficed with the design, cad drawings will be on my patron.
How long it will take to come to market?
we have a ways to go, so far it looks like our patreons may be the only ones for a while that will be able to buy a turbine. Once we get enough equipment to build many turbines it will be available for everyone.
You could start a tractor with that
it's interesting, you could actually power a tractor with it when the supply volume is properly sized
