How can open ocean currents generate energy? Ocean currents contain kinetic energy that can be converted to electrical power using turbines. This is similar to offshore wind farms, or wind turbines ...

Inspired by the classic drinking bird toy, scientists have developed an engine that efficiently converts energy from water evaporation into electricity to power small electronics. The device produces ...

Readily available thermoelectric generators operating under modest temperature differences can power CO2 conversion, according to a proof-of-concept study by chemists. The findings open up the ...

There's that relief that follows when power goes out and the sound of a generator kicks on. In just a few seconds, your lights are back, your A/C and fridge are up and running, and you don't have to ...

Japanese researchers at Kyoto University announced in December 2025 that they invented a coin-sized generator that creates 24/7 electricity "out of thin air." In December 2025, Facebook users shared a ...
