Check this out you can now get free power from waste heat, real power :D

Now that will be a really big deal if they start generating electricity on a local level without the need for long transmission lines. Not to mention it's "clean" power. Goodbye smog?

Would it be possible to generate electricity from this apparatus? If so, could some of that electricity be diverted to short the bottom of the hot water half, so that the hot water stays hot?

Pretty cool, but I reckon peltiers are more efficient, just heat one side then cool the other. Reminds me of a failed project to generate power from the heat of my urine... Both unproductive and messy. :(

You could very well be correct about a TEC being more efficient but do they cost less to manufacturer ? I believe they were saying that if the metal could be produced for under $200.00 a pound it would be viable thing to do.

If it can turn a wheel it can turn a generator or a pump so hot water could be produced by the sun and turn the pump to pump water for the town, is it cheaper than solar cells or peltiers ?

Still, even solar power is cheaper and more efficient.
(not photovoltaics, but when water is heated to steam, and the steam is used to turn a turbine connected to a generator; or Stirling engines that use focused solar power)

What's the minimum heat difference it can run on? <- probably not phrased right, but still.
The main usefulness of a Stirling engine is that it can work off a very small heat difference, as compared with TECs, right? In fact, IIRC TECs are some of the least efficient ways to generate electricity from heat.
Obviously this is neither a TEC or a Stirling engine, but still, is it better than either in any way?

It was spinning that wheel pretty fast with a 20 degree difference is what I believe I heard.

So for people who had low temp thermal springs on there property this could be a good thing :thinking:

I think your right you need a significant temp difference for TEC's ?

So if you had stem coming out of the ground a TEC would be the way to go then ;)

The one thing that took me was it gets stronger with age and works better after it's been in service for a while
he said the wheel had made 23,000,000.0 revolutions in 3 months or something like that, how much power can
you generate with 23,000,000.0 revolutions :crackup:

Power is one thing, speed is another... you must not forget torque.
