Scientists in Japan have developed a new organic device that can harvest energy from heat. Unlike other thermoelectric generators, this one works at room temperature without a heat gradient. Usually, ...

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and their colleagues have discovered a new relation among electric and magnetic fields and ...

As the planet warms, more people need air conditioners—but traditional ACs use a lot of energy and exacerbate global warming. The Gradient ($1,999, pre-order for 2023 delivery) aims to break this doom ...
