A new thermogalvanic device uses nanoparticles to control ion flow, allowing it to convert waste heat to electricity and store the energy without external batteries. (Nanowerk Spotlight) Heat is ...

The prototype delivered 13 per cent conversion efficiency, which, in simple terms, meant that with the prototype, for every 100 units of heat energy that went into the device, about 13 units were ...

The thermoelectric effect is a phenomenon that can help turn heat into electricity. This works by having a temperature difference produce an electric potential, as electrons flow from the hot side to ...

Data centers generate a lot of heat, which usually goes to waste. These companies see that as an opportunity. But can they scale?

Laura Schaefer, the Burton J. and Ann M. McMurtry Chair of Mechanical Engineering at Rice University. When you stream a movie, back up a photo or ask ChatGPT a question, somewhere a data center is ...

According to Gneuton, the solution is a closed-loop system and can harness the untapped thermal energy from gas turbines to ...
