Steam power is poised to make a comeback using energy from exhausts
I found another article around using energy from exhausts.
It descibes how steam power is poised to make a comeback as a way of using heat wasted by car exhausts. anywhere where you are wasting a lot of heat, we can go in, capture the heat and turn it into energy savings
“A tank of petrol or a tank of diesel is such an incredibly good energy store that we have been able to afford to throw some of it away up until now.”
Of the energy in a car’s petrol tank, just 27% is converted into forward motion, while 36% is lost as exhaust heat. Of course the implications on exhaust systems within racing could be immense.

How Exhausts Could Save On Fuel Bills
I discovered a great article on how heat capture technology could cut car fuel bills by 10 per cent while increasing performance!

What a great way to improve performance and effiencientcy at the same time.
