The Spin Seebeck Effect to Offer Low-Loss Thermoelectric Effect

Eiji Saitoh experimented with a heated magnetized metal (nickel-iron), and found out that the electrons with up spins (aligned with the rod's magnetic field) created an agglomeration on the hot side, while the ones with down spins (unaligned to the rod's magnetic field), created an agglomeration on the cooler side.

GM to Research Shape Memory Alloy for Heat Recovery Systems

GM's R&D has to build a prototype of a thermo-mechanical waste heat recovery system using a Shape Memory Alloy (SMA) heat engine to generate electricity from the heat in exhaust. Noticeable is the fact that GM was between the 37 other candidates that received the ARPA-E award.
