The million-dollar question is, does it produce enough torque to turn a generator motor? I'm not doubting the technology, it's just that I have yet to see one of these videos actually show one producing usable electricity. I hope they do, because it's a brilliant idea!

Now THIS is good. Sterling Energy Systems (SES) and Infina are actually manufacturing these. SES is working with Southern Cal utlities to develop large scale plants. Infinia is after the residential/commercial buidling market.

where do I buy one?

I'm guessing your talking about a larger version... didn't he say that this produces 30kw a day which is the same as the average use of an American home? I think that lots of smaller units would be safer and more efficient... no energy transport, no loss, no dependency on a central system...

1 unit can power 10 homes for 25 k,so you figure thats 10 Americans with 1 years worth of a average tax return then there energy free, off the grid.This will only work if we all contribute information and awareness,truly left up to each and every one of us.See but we are all to quick to discount out own impact,this whole concept can move as fast as a thought,so whats your thought, beneficial or non-beneficial?

There's a German company that uses the waste heat from furnaces to run sterling engines to power generators. The electricity produced is sold back to the electric company.I don't think the hot air exhaust of an AC unit would contain enough energy to do any useful work though.

You may note, they're claiming free "energy" not free materials or construction.Obviously it's going to cost money to build and maintain. But you don't have to pay for sunlight - the energy it runs off of.

I don't believe it can be done.

Free after set up. Theres no such thing as free energy, if you consider the startup cost. The point is to produce energy that surpasses the startup cost in value.
