Guys I think you are missing the point during WARMUP and ENGINE START things are EXTREMELY inefficient and in the case of ethanol (hydrous as well) you can't start at all.

To heat 1 gallon/hr of water 410 degrees takes about 1000 watts continous or about 1 1/3 hp.

So on a big V8 that is how much power would be needed to achieve this but again this would only be during warmup and given many vehicles use 2x - 3x more fuel during warmup (at least at idle) this may not be a bad investment even on non-e85 vehicles.

Heck idle consumption is all waste and that is where this would likely make things a WHOLE lot better.

Especially for the non hypermilers who insist on warming their car up 15-30 minutes.

Cheers
Ryan
