i hate to be a doubter, however you would be better off pointing some little steam nozzle out the back of the car and using it for its tiny thrust output. that way the energy could be used to do something directly instead of using it to spin a shaft, which has air drag, and bearing drag, and converting mechanical energy to electrical via a 3 phase alternator, which then converts 3 phase a/c into dc, etc etc.

how many mpg would it increase as a thrust motor? whatever that small number ends up being, its got to be more then making electricity with the same power.


besides, i dont think the thrust of a 5hp 3000psi pressure cleaner would spin an alternator and get any sort of decent numbers, much less some water boiling in the exhaust. and steam is never going to get close to 3000psi or a few gallons per minute of flow.

the final problem is, most ecomodders do not open the throttle on their engines to very much load and rpm's. the exhaust just doesnt get very hot unless you burn lots of fuel which is the opposite goal of an ecomodder. by "hot" i do not mean the temp. i mean, the for lack of better words, the "sustainable heat energy". my 30watt radioshack soldering iron can boil water, and rather quickly too. but it doesnt have enough heat energy to power a turbine driven alternator. i also do not think the exhaust of a typical ecomodder car does, either.

the only way it would have a change of working is if you scrapped the car alternator idea and instead used a tiny motor like that out of a r/c car or a desktop fan. maybe just maybe you might get enough wasted energy out of an ecomodders exhaust to spin something that small.
