BMW turbosteamer concept

Quote Quote by Ayrity
ya i thought about a steam regulator, but maybe a cvt could do 2 things at once, that way you wouldnt need seperate valves and a teperature switch etc etc. (in terms of what i could replicate at home at least haha) what do you think would be more efficent for heating water by exhaust for a teat at home? wrapping some copper tubes around the exhaust pipe? a radiator?, and also for the turbine, would half a turbocharger work well?
I would think that the radiator would be the better bet since it would maximize the surface area that is responsible for the heat transfer. You could try the coil, but there would definitely gaps, etc that would reduce the effectiveness. It would be very easy to make a coil though. So I would, if I were to try to replicate this, try the coil first.

The turbo is the basis for many a home made turbines. You have to get them turning at very high speeds though. That may be an issue. I'm not quite sure of the size they're using on the BMW. I only skimmed the article.
