You may even open up another branch of physics at these speeds. Next, you can approach 10 percent the speed of light. Use this as a rocket to explore the stars. Keep up the amazing work.
225w under load x 24 hrs is barely 5.5kwh @ 30v x 7.5a per hr if it could run for an hr lol, i love the idea of this tech i just realllly hope it scales as well as i think it should. not hating but if you want anyone to take you serious slap a gear system on this and attach a damn 5kw axial flux alternator and get hella watts per hour or die trying lol, this with a 22kwh per day output could power a house with solar heating in alot of places. dope build keep it up i hope something like this replaces reactors one day.
Check out my previous video: that was a polycarbonate turbine, so I couldn't let it get too hot. I've managed to generate over 2 kW with it. My new turbine, however, features an aluminum housing and titanium disks, and it's capable of much more. It can easily exceed 5 kW and has the potential to reach 40 horsepower if operated at high enough pressure and temperature-assuming the shaft can handle the torque without twisting off.
That’s why there’s a blast shield around it. A magnet exploded during a previous test at 99,800 RPM, but I was protected. In the future, we can reinforce it with carbon fiber or Kevlar wrapped in epoxy to make it stronger.
I always love the laminar flow of the Tesla turbine . 10 years of age I was using the hose to clean out a Paint roller and found that I could get it spinning at great speed just by squeezing the end of the hose to create more pressure and I've been fascinated by the concept and of course people have been building wonderful little Tesla turbines and as much as it's not the answer to all things it certainly has its place that is just not being really utilised micro energy. Storage as every time you turn your tap on on your house or have a shower that could pressurise air first spin up a Tesla turbine for a period of time and stole the energy into batteries that could use for nighttime lighting in a house so Justin the water supply that is pressurised we lose all the energy by not taking advantage of it when we open the faucet in the Home and in fact in the 1940s or somewhere near there they did actually have these little dynamos. I think in England that used to create, a small amount of electricity for whatever use they had then
Great Jeremiah! Thank you for sharing your progress. One very intriguing application for the tech, aside from the whole our-of-the-grid home thing, is as an addition to a ICE water cooling system for hybrids, to recharge the car batteries not only with the mechanical power of the rotating shaft, while the ICE is running, but also with the most of the heat which usually is wasted away (about 60-70% of the total energy) through the radiators.
You should get an inlet needle valve for higher levels of control. That way you could ramp it up and see how much flow you need to start it spinning at certain loads, if that's something you care about.
Not too hard, I have a system that runs constant now, just waiting for main valve control board. This was just a side experiment, the real stuff is on patreon and will soon come to RU-vid.
You're right, using low pressure water is safer than organic solvents for low temperature engines. Problems might be with the non linear graph. 40C might need 1psi. So everything needs to be 15 times the size for the same power as boiling at atmospheric pressure? But you can get night electricity from warmish water, and covered ponds is easy to get lots of this. Need a closed system in the engine half, and a condenser in closed loop in the engine? PV + batteries, not the 1950's? Expect lots from 70 years ago, might still be good, now control is so much easier + precision computerised engineering and parts availability. If you have a 48,000 litre tank of water at 40 C (swimming pool size), you'd be lucky to get 400kWh of electricity. As soon as the temperature goes under 40C boiling anything gets difficult. Need to batch the heat exchange. Heating to 70C+ with PV makes it much better.
I'm assuming we can get more power at lower temperatures with different gases so we will just have to test and find out I definitely want to test different gases
Hello Jeremiah. I was wandering. How much watts can you pull from this small turbine? Is the fluid mixed steam and air? Are you planning On making an endurance test? Like running the turbine for hours or even days.
The power output in these tests was limited by the generator. Theoretically, I could achieve several kilowatts with a more powerful generator, but only further testing will reveal the actual limits.
@@peterfitzpatrick7032 I know Ohms Law; I did see it was between 200 and 500 watts, but I meant to ask about the theoretical limits of this particular turbine.
Dude, you don't need to show rip'ems. You can just show the hz of the power being generated. That's basically the same as showing RPM. Flip that fake Fluke from flow to Hz.
I tried, but the frequency became unstable at around 32,000 RPM. To measure the RPM, I analyzed the sound using the Spectroid app, which I’ve found to be very accurate when compared to an actual RPM meter. In this test, using an RPM meter wasn’t possible because the shaft was not exposed.
Love the sound of the turbine. such a unique sounds. thanks for showing us the tests. How long could you run it to say power a home or charge a large battery bank for later energy use?
If you saw the larger turbine before I tested the smaller one, that larger turbine is the one that can power your house. You just need to heat the thermal mass/battery to a suitable temperature.
Doesn't the cold steam setup use less applied energy and still get the same output? Also Why does the load slow it down? is it the winding or use of a magnetic field causing a torque or a drag-ah what's the word? I lost my train of thought😢😂. Not static friction..lol. just why. 😅
Great questions! The cold steam setup does use less applied energy due to the efficiency of phase change and heat transfer processes, but the actual output depends on the overall system design and losses involved. As for the load slowing it down, you're probably thinking of 'back EMF' or 'counter torque.' When a load is applied, it creates resistance against the motion, increasing the demand for energy. This can be due to several factors, like magnetic drag, mechanical friction, or electrical resistance in the windings. All these can cause the system to slow down as it tries to maintain balance. No worries, it's a complex topic, and losing your train of thought happens to all of us! 😅
You haven’t seen my latest progress on the large turbine. You can also convert torque from a generator to a motor to get as much torque as you need. However, comparing the two isn’t really relevant because the turbine serves a completely different purpose than a piston engine for what I am doing.
That seems fairly inefficient. The 500W extracted from the turbine compared with the couple kW to go into supplying the air to make that 500W. Running the generator at high frequency is potentially problematic depending on the rectifier. The 1500Hz isn't really fast but the high current rectifier might be quite slow. The relatively low voltage of 50V is also quite lossy if you're using a silicon diode rectifier. It'll have 1.4-2.0V across it depending on it's specs and the current. This means that you're losing about something like 4% of the energy just in rectifier losses. You can get a frequency measurement in real time quite easily if you use 1 of the 2 meters on the Hz range.
I suspect you actually know the energy efficiency is about energi in vs energy out, not power in vs power out. Still, one small Tesla turbine can't be very efficient. Your point about losses in rectifying the voltage is valid, if it the voltage is rectified, which isn't necessary to run incandescent lights. They can redesign the generator to increase the voltage. They're experimenting, not showing a finished product for sale. Also, ~4% additional loss in rectifying isn't much in that context. Consider the videos as entertainment. BTW nice to see that you use the proper unit symbols, I think the convention is leaving a space between the number and the symbol in common text, but hey, just using the right symbols is rare in youtube comments.
Thanks for the detailed input! You’re right; there are efficiency challenges when matching the input power to the output. The goal of this setup was to demonstrate the concept and the potential of using various heat sources to drive the turbine. I’m currently focused on optimizing the entire system, including the generator and rectification stages, to reduce losses. For the main project, I’m working on a larger turbine paired with a coreless generator that outputs 400V. With this higher voltage, the rectifier losses should be much lower, making the system more efficient. I’m also considering using more advanced rectification methods, like Schottky diodes or MOSFETs, to further reduce voltage drops and improve overall performance.
It would be great to see a system that could take me off the grid here on the farm - I have PLENTY wood fuel for steam production. Keep up the good work - it will pay off.
This is exactly what you need if you have a good supply of wood! Stay tuned for updates, and consider joining my Patreon for exclusive insights on the turbine we're running on heat. Even free members receive updates occasionally.
Nice test with humid air if you can make it run for a few hours while it is producing 500 watt that would be something 😀 i wonder what the nozzle diameter is ?
Ok INsANE idea what if you inject a fuel air mixture into the turbine, have the turbine spit it out of its exhaust, then ignite the exhaust and feed it into an axial turbine. TESLA turbine Turbojet
@@donavonneighbors Maybe some time we will accept some visitors, I would have to get an ok with my partner. Can I get your email, if you send it delete it shortly after.
Or we could just increase the temperature, which isn’t too bad for a laminar flow turbine. However, I’m curious to see how a dryer would perform in this setup.
I suggest using Current Clamp for the Amps so you're not limited to 10A but instead you have up to 20 or 60A. I just bought myself PeakTech 4250 which has great value for the money and 4mm banana plugs for the multimeter. It's the same hardware as Pico TA018 but without BNC and shielding - which you can add yourself for cheap. Not to mention this hardware is mainly used with the oscilloscope so you have current frequency response up to 20 kHz. Looks like the project is getting further and better, keep up the good work!
I have a clamp-on ammeter, which I initially planned to use, but it wasn’t reading correctly. I later realized it was set to AC mode. Next time, I'll make sure to use it properly in the correct mode.
Currently, we are working on a system that utilizes a thermal reservoir to power a turbine. My latest tests focus on this approach, which allows for the thermal mass to be charged with almost any heat source to generate electricity.
Something I have wondered with Tesla Turbines having a hard time converting their speed into torque.... is there a way to use a gear system (like a bike) that can be increased as more momentum is built to spin a series of increasingly large Flywheels or multiple of them in succession to make the motion more useful? Say even as a solar battery system, where they would get faster and more mass during the middle the day and as the solar drops off at say 4pm, then the momentum built by the flywheel could be utilized? In my brain, this idea could also be best used in a hydro dam or on a waterfall or something.
Amazing Build! This is the first time I have ever seen someone actually build and operate a Tesla boundary layer drag turbine on RU-vid. The experiments are definitely promising. Have you done any experiments with larger disc diameters and say using water/ gravity as feed for one?
Thank you for the kind words! I’m glad you enjoyed the build. I’ve been focusing on optimizing the system with various heat sources and improving efficiency. Check out my previous videos to see my larger 6-inch rotor, which generates significantly more power and is driven by a thermal battery/thermal reservoir. Currently, I'm testing the turbine using a thermal reservoir that can be charged with different heat sources to produce electricity. I have successfully experimented with using water and gravity as well, although I haven’t published that on RU-vid yet. Exploring larger discs could further enhance performance and open up new possibilities.
lol now you can boiling the kettle with enough air providing a major bearing failure doesnt occur which it will without oil feed and/cooling. Damn it, back to the drawing board once again😂😂🤣
These bearings have withstood several rotor crashes caused by misalignment, which I've since corrected. Amazingly, I've been testing with the same bearings for over 4 years, and they’re designed to run without oil. With the alignment issues resolved, no more crashing rotors! My new 6" turbine is now bulletproof. Cheers!
@@timh.2137 fffs, it isnt even worth explaining... but i will anyway, though i get the impression you wont understand, or want to understand. if the air is supersonic, and the blade moving within that air is also supersonic, it doesnt produce a "boom" because the relative speed between the two is NOT supersonic. anyway, a "boom" is a single wavefront, a single rapid rise of pressure, moving past you. not a continuous sustained note. when a propellor tip exceeds SoS, theres also no "sonic boom", but it does make an awful "tearing" sound... very distinctive. fun fact, air exiting a nozzle at anything over 16 or so psi is already travelling at sonic speeds...
The terubine is a turbine with a 1000x more bines than a gigubine, and a 1,000,000x more bines than a megubine. That's why he lowered the pressure. The tur/bine ratio is way off and you have to lower the speed to get the right ratio.
