They are saying they are only going to return 4-10 KW (5-13 Hp) back into the engine. That's not a lot. They aren't claiming this is going to be a turbo booster where you mash the gas and your car takes off. When you are just cruising down the highway (NOT at 130) it only takes maybe 20-30 horsepower to keep your car moving along but your EGT (exhaust gas temperature is still high). Why couldn't you recover this waste heat? I worked on stirling cycle engines for several years and they sort of did the same thing using waste heat recovery.

I'm not saying this is a plausible idea mechanically with the additional parts or additional drivetrain loss but I would like to see it in action.

Downstream fuel injection and ignition. afterburners for your car.

You can't just buy an iPhone off of e-bay and pop your SIM in. It WILL NOT work. Believe me I tried. You have to activate the phone so it pairs to your SIM. Unless you use a third party program to activate the phone you will be extending your contract for 2 years.

I hope I win
