U Michigan team boosting efficiency of thermoelectric materials; potential of reaching 15-20% efficiency could result in practical applications

Green Car Congress

At that level of efficiency, TE materials become useful in practical applications such as waste heat recovery in vehicles, Kaviany noted. But we did not know what features we could manipulate to maximize the conversion of heat into electricity. Example of the structure of a partially filled CoSb skutterudite. Click to enlarge.

MSU microbial electrolysis cell produces ethanol from glycerol, reduces wastewater in biodiesel production

Green Car Congress

Researchers at Michigan State University have developed a microbial electrolysis cell (MEC) which will allow biodiesel plants to eliminate the creation of hazardous wastes while reducing their dependence on fossil fuel. Geobacter removes any waste produced during glycerol fermentation to generate electricity. Click to enlarge.
