An international team of scientists looks to provide a potential path to generating electricity like solar cells but that can power electronics at night. Some have observed that for a device on Earth facing space, which has a frigid temperature, the chilling outflow of energy from the device can be harvested using the same kind […]

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, […]

Fraunhofer-Gesellschaft researchers have developed a compact, safe and sturdy fuel cell system that generates electricity and heat in private households from natural gas. The new fuel cell converts chemical energy directly into electrical energy in a design developed as a simple device for home use. If the design is scaleable it might be a market […]

Stanford University engineers have devised a new way to generate electricity from sewage using naturally occurring “wired microbes” as mini power plants.  The exoelectrogenic microbes produce electricity as they digest plant and animal waste. The laboratory prototype is about the size of a D-cell battery and looks like a chemistry experiment, with two electrodes, one […]

Fuel cells are for some the nirvana of portable or mobile energy production.  But the problem of a catalyst that tears the hydrogen atom into the parts needed to generate electricity still bedevils the progress to widespread commercial marketability. The best catalyst for efficiency is platinum, the rare, expensive, and beautiful silvery metal.  Other ideas […]
