Solar Thermal Waste Heat Engine works at low temperature, low pressure

What happened to acid dewpoint?

At the extremely low temperatures heat is often useless due to acid characteristics of the gas stream.

This is probably a useless invention.

euss, even if you were correct, the invention would still be a far greater contribution than your comment. Who ever said you had a clue?

The idea is amongst the G2 concepts, which rightly suggest we make secondary use, recycle, per se, the energy. It makes perfect sense. When we use a gas heater, it's foolish that we don't install a heat exchange unit in the exhaust pipe, to heat fresh water as well. It's wasteful not to make full use of the energy expended.
