Thermoelectric devices turn waste heat into electricity for vehicles and other machines
It's estimated that more than half of U.S. energy—from vehicles and heavy equipment, for instance—is wasted as heat. Mostly, this waste heat simply escapes into the air. But that's beginning to change, ...
Harvesting energy from devices
If there's one thing nearly all modern technology has in common, it's heat. Whether it's your car, computer, television, or even refrigerator, they all generate large amounts of heat. And nearly all of it ...
Granite research revises heat under Perth's surface
Scientists investigating heat decay from radiogenic granite in the Darling Range have discovered the maximum heat output has exceeded previously known data.
Planning in the near term for climate change
When scientists talk about climate change, they usually mean significant changes in the measures of climate over several decades or longer. Climate variability generally refers to seasonal changes over a ...
