With this technology you could use a different liquid source for energy and make the components necessary to power a vehicle (on the ground).]]>Jul 29th 2008 6:58PMhttp://www.switched.com/2008/07/28/super-efficient-material-converts-car-exhaust-to-energy/http://www.switched.com/2008/07/28/super-efficient-material-converts-car-exhaust-to-energy/
This idea is a form of cogeneration, already used in large industries, especially power plants. Cogeneration usually increases efficiency from 55% to 89% in power plants. The difficulty with putting these cogeneration facilities into cars is weight and pressure. If the exhaust is significantly slowed down or stopped to be put into some other component it causes problems with the engine.

As for the car itself most engines will get 20-25% efficiency, and the maximum possible (according to the laws of thermodynamics) is 37%.
If you can recover 1% of that energy and put it back into powering the car you increase the fuel efficiency by 4 - 5%.]]>Sep 9th 2008 1:54AM
