UCLA researchers capture wasted heat, use it to power devices




Imagine how much you could save on your electricity bill if you could use the excess heat your computer generates to actually power the machine.

Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have taken an important step toward harnessing that heat and converting it for practical use. The advance could lead to more energy-efficient appliances and information processing devices.

The research team, led by Kang Wang, UCLA's Raytheon Professor of Electrical Engineering, demonstrates how to add power to a spintronics device, which uses the spin of electrons for energy rather than their charge.
