The energy systems that power our lives also produce wasted heat—like heat that radiates off hot water pipes in buildings and exhaust pipes on vehicles. A new flexible thermoelectric generator can wrap around pipes and other hot surfaces and convert wasted heat into electricity more efficiently than previously possible, according to scientists at Penn State and the National Renewable Energy Laboratory.
“A large amount of heat from the energy we consume is essentially being thrown away, often …
