Peter Hagelstein, an MIT electrical engineering professor, found a better way of getting electricity from waste heat. He combines thermoelectrics and thermionics in a device that converts about 17% of the heat it absorbs into electricity. And, he says, 20 to 25% is possible with improvements.

Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
