A sound way to turn heat into electricity
University of Utah physicists developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling computers and radars.
MIT's wireless electricity demoed, dubbed WiTricity
A team of Massachusetts Institute of Technology researchers reported in Science Express, the online publication of the journal Science, that they had demonstrated wireless transmission of electric power by magnetically coupled resonators. They dubbed their technology "WiTricity" for wireless electricity. -via Engadget
