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% Click to enlarge.

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.

Researchers use CaO catalyst to produce biodiesel/monoglyceride blend; avoiding waste glycerol

Green Car Congress

The resulting blend exhibits properties similar to conventional biodiesel, while reducing waste and improving conversion. The generation of glycerol not only represents a notable performance loss in the process, it is also creating an enormous waste problem. —Calero et al. Juan Calero, Diego Luna, Enrique D.

However, despite decades of effort, no lab-developed catalyst for achieving that conversion has been commercialized. If successful, these mechanical analogues of turbulence could transform the way energy-harvesting systems are designed, yielding much higher conversion efficiencies than achieved in traditional configurations.
