Tesla Turbine Spooling up on 20kW Steam.wmv

Tesla Turbine / Boundary Layer Turbine / Teslajet Turbine, Spooling up on 20kW of steam, approx. 300C at 40psi boiler outlet conditions with surges of water from monotube boiler heating up. Bicycle disk brake rotor is working as a fan at these high rpms preventing turbine run away. Turbine appears to be putting out around 1kW shaft power or around 5 percent thermal efficiency of energy conversion.

@walperstyle.........

This system is headed for typical steam power plant, turbine, to make electricity plus heat for house, hot water, hot tub, sauna, swimming pool..... The boiler will make high pressure high Temperature steam for the turbine. After the turbine, the cooler steam than flows into a condenser. Heat of condensation is large, so heats the 1500 gallon reservoir of hot water for other uses. You reclaim that heat, and use it. That's why efficiency can be high.

Heat and electricity.....ultimately.  fun for now.

As for the physics, these are all just simple steam turbines so nothing fancy. They are boundary layer, sometimes called Tesla, turbines. Steam flow drags the rotor pack. The way this is superior is that you can use the "waste heat" to heat your home or business. That's Co-Generation, heat plus power, and when you account for the heat used, the efficiency rises into the 70% to 90% range depending on how well your system works. So, yes, it is in that sense superior to a power plant.

This turbine has around 5 percent efficiency, really low.  The boiler kicks out 40kW in steam. So that works out to something like 1kW shaft power for this turbine. The "load" is the fan it's spinning at 20krpm. Yes of course if you load it with a generator, it would slow down, but if you took off the fan it would speed up........you could get about 1kW off this turbine. My new turbine will hopefully break 30 percent efficiency but 20% would be a great start. We'll see in spring,

@woodfirepower Explain what you mean by "The difference, however, is that with a personal turbine in Northern climates, you can use the heat, 80+%".

I use to work a lot with boilers. You need a heavy fuel source to make steam. When you have steam circulating, you can gain a little energy back, as long as you are venting the steam to air. Otherwise its dead-ended, not doing anything, and your lines will freeze.

what is the application? 

[woodfirepower]

@ozzirt Actually, the fan IS the load. It's blowing air around and burning up around 1kW by best SWAG..........scientific wild ass guess........... Anyway, remove the fan, speed would go up, install generator, speed would come back down. Peak power would result at a bit lower rpm and genset would lower it to that level if operated properly.

@walperstyle This particular turbine is NOT superior to other turbines. To the contrary, it's far lower efficiency. Something around 5 percent thermal vs 40 to 60 percent thermal for a good power plant.  The turbine I am developing, see New Turbine videos, will hopefully be far better than this one, though most likely it will fall short of power plant class turbines. The difference, however, is that with a personal turbine in Northern climates, you can use the heat, 80+%

Thanks for the interest. I have more work to do prior to any sales can begin. The turbines need to run more efficiently.  keep watching and with luck I'll have something by summertime.
