Politecnico di Torino engineers have developed an innovative, low-cost technology to turn seawater into drinking water using solar energy alone. According to FAO estimates, by 2025 nearly 2 billion people may not have enough drinking water to satisfy their daily needs. One of the possible solutions to this problem is desalination, treating seawater to make […]

Purdue University scientists have developed a new material and manufacturing process that would make one way to use thermal solar power – the heat energy – more efficient in generating electricity. Solar power accounts for less than 2 percent of U.S. electricity but could make up more than that if the cost of electricity generation […]

University of Tokyo physicists have discovered a new way to generate electricity in special materials called Weyl magnets. The method exploits temperature gradients, differences in temperature throughout a material. The technology could offer new designs for maintenance-free remote sensing devices or even medical implants. Professor Satoru Nakatsuji of the Institute for Solid State Physics said, […]

Sandia National Laboratory researchers have developed a tiny silicon-based device that can harness what was previously called waste heat and turn it into DC power. The rectenna, short for rectifying antenna, is made of common aluminum, silicon and silicon dioxide using standard processes from the integrated circuit industry. Converting electrical power to heat is easy. […]

Hokkaido University researchers have more than doubled the ability of a material to convert heat into electricity. With progress in development it could help reduce the amount of wasted heat, and thus wasted fossil fuel, in daily activities and industries. The researchers and their colleagues in Japan and Taiwan have improved the ability to transform […]
