Engineers at CU Boulder have debuted the world’s most efficient optical rectennas—devices that are thinner than the width of a human hair and can capture waste heat and turn it into usable power. The ...

One such promising avenue is thermal energy (electrical) storage (TES) systems, which store electricity as thermal energy by converting it into heat, which can later be converted back into ...

“Flexible thermoelectric devices can be worn comfortably on the skin where they effectively turn the temperature ... the film's ability to convert heat into electricity and gives it flexibility.
