Researchers have built a small-scale computer that runs on thermal noise, the random electrical fluctuations that conventional chip designers spend billions trying to suppress. The device, called a ...

Physicists developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling ...

Researchers at the Lawrence Berkeley National Laboratory have developed a design and training framework ...

HERE'S HOW IT WORKS: A palm-sized, cylinder-shaped resonator contains a stack of material with a large surface area such as metal or plastic plates, or fibers made of glass, cotton or steel wool. The ...
