University at Buffalo engineers have designed a new system to help cool buildings in crowded metropolitan areas without consuming electricity, an important innovation as cities work to adapt to climate change. The system consists of an inexpensive polymer/aluminum film that’s installed inside a box at the bottom of a specially designed solar ‘shelter.’ The film […]

A University of Michigan finding runs counter to a common assumption in physics. The researchers ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away. The approach could lead to new solid-state cooling technology for future microprocessors, which will have so many transistors packed into a small […]

Shanhui Fan, an electrical engineering professor at Stanford University in California has found a way to let photovoltaic solar cells cool themselves by shepherding away unwanted thermal radiation. By adding a specially patterned layer of silica glass to the surface of ordinary solar cells, a team of researchers may have overcome one of the major […]
