"A group of researchers have created a metallic device which is attached to the exhaust pipe, producing electricity from the otherwise wasted heat: a thermoelectric generator, a device that uses temperature differences to create electricity. When installed on a Chevy Suburban, it improved by 1mpg (which is 5 percent)..."
