Electricity generated from a WFO, Sure, this crowd seem to be working on something, How do you think it works? Steam power is all I can think of?

Either steam ( since they mention hot water) or some kind of bi-metalic strip. But I can't see it producing too much energy. The steam idea might work but the safety factors ( PRVs etc) would end up making the system costly and expensive. I think it's a pipe dream

Don't discount the pipe. It can be instrumental in the production of some very innovative ideas.

Not at all. A sterling engine would be the ticket. I don't understand why they are not mandatory in every chimney. Hot and cold equals power. Hell - hot and less hot equals power.

I did think sterling engine but it also seems out of the question, maybe a combo of everything possible, surely the pressure rising from the chimney alone would turn a prop, pressure from the hot water a piston and generated heat a sterling engine.

"pressure from the hot water"

Pressure ?

Unless you are a boiler engineer, I would hesitate to try a home made pressure system.
