BMW Partners With NASA On New Thermoelectric Exhaust System

BMW has revealed a partnership with NASA to develop thermoelectric generators for its next-generation Efficient Dynamics Mk2 system which uses a little bit o' ultrascience to make 200W from wasted exhaust gasses. » 3/11/09 9:00am 3/11/09 9:00am

Researchers Continue Attempts To Turn Car Exhaust Into Power

The Department of Energy is funding research at GM and BMW, along with several partner universities, into a little-known technology called the thermoelectric generator. Internal combustion engines use a grand total of maybe 25-30% of the energy contained in gasoline for actual propulsion. Everything else is wasted… » 8/11/08 1:40pm 8/11/08 1:40pm
