Pulling energy out of the air

Power Puck

Scientists at Pacific Northwest National Laboratory have developed a technology that extracts energy from its surrounding environment, creating a perpetual power source for compact, low-power devices such as wireless sensors or radio frequency transmitters. The Thermoelectric Ambient Energy Harvester exploits naturally occurring temperature differences, producing electricity whenever it detects these differences across the device's two ends.

DOepatents was developed by OSTI. More information about technology transfer may be found at the DOE Technology Transfer website. Questions about technology transfer at the U.S. Department of Energy may be addressed to DOEtechtransfer@science.doe.gov.
