Purdue University researchers with an international team of collaborators have used a ‘thermal metamaterial’ to control the emission of radiation at high temperatures. The advance that could bring about devices able to efficiently harvest waste heat from power plants and factories. Generally, its known that about 50 to 60 percent of the energy generated in […]

North Carolina State University researchers have developed a new design for harvesting body heat and converting it into electricity for use in wearable electronics. The experimental thermoelectric generator prototypes are lightweight, conform to the shape of the body, and can generate far more electricity than previous lightweight heat harvesting technologies. The researchers also believe they […]

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 […]
