MIT engineers have invented a bubble-wrapped, sponge-like device that soaks up natural sunlight and heats water to boiling temperatures, generating steam through its pores. Bubble wrap and a sponge? The design the researchers call a ‘solar vapor generator’ requires no expensive mirrors or lenses to concentrate the sunlight, but instead relies on a combination of […]






A research team in Japan discovered that nanoparticles of transition metal nitrides and carbides absorb sunlight very efficiently. Using numerical calculations and confirmed experimentally they found that nitride nanoparticles dispersed in water quickly raise water temperature. The nanoparticles may be used for heating and the distillation of water by efficiently using sunlight. The research team […]






Sweden’s KTH The Royal Institute of Technology researchers are using thermoelectric generation to save vehicles hundreds of liters of fuel and reduce their carbon emissions by as much as 1,000 tons per year. Working with automotive manufacturer Scania, the researchers from Sweden’s KTH Royal Institute of Technology have been testing semi trucks equipped with a […]






Researchers at Tohoku University have announced a new thermoelectric device using cutting edge thermoelectric conversion technology. Thermoelectric conversion technology converts energy abandoned as waste heat back to electric power that could potentially save lost energy. The new technology, known as the spin Seebeck effect, has conversion efficiency 10 times higher than the conventional method. Although […]






Many phenomena in physics, though well-known, are not necessarily widely understood as is the case with thermoelectricity. Thermoelectricity is the phenomena that harnesses waste heat by coupling heat flux to build an electric current. Understanding such phenomena is important in order to leave the door open for discovering novel manifestations of them. Even today physicists […]
