MIT/Stanford team develops battery technology for the conversion of low-grade waste heat to power; TREC

Green Car Congress

Researchers at MIT and Stanford University have developed new battery technology for the conversion of low-temperature waste heat into electricity in cases where temperature differences are less than 100 degrees Celsius. These features lead to a high heat-to-electricity energy conversion efficiency of 5.7%

NEC, NEC TOKIN and Tohoku University develop spin-Seebeck thermoelectric device w/ 10x better conversion efficiency

Green Car Congress

NEC Corporation, NEC TOKIN Corporation and TOHOKU UNIVERSITY have jointly created a thermoelectric (TE) device using the spin Seebeck effect (SSE) with conversion efficiency 10 times higher than a test module that was produced based on a multi-layered SSE technology published by the Tohoku University group in 2015.

UCR team demonstrates use of earth abundant elements in spin-mediated thermoelectric energy conversion for waste heat recovery

Green Car Congress

Mechanical engineers at the University of California, Riverside, have successfully used inexpensive materials to produce thermoelectric devices that transform low-level waste heat into electricity. The spin to charge conversion takes place in the NM (usually heavy metal) due to inverse spin-Hall effect. —Sandeep Kumar.

PNNL biocrude-to-diesel demo passes 2,000-hour catalyst stability milestone

Green Car Congress

The biocrude oil came from many different sources, including wastewater sludge from Detroit, and food waste collected from prison and an army base. The research showed that essentially any biocrude, regardless of wet-waste sources, could be used in the process and the catalyst remained robust during the entire run.
