Hot Advance for Thermoelectrics
Cheap organic molecules could more efficiently convert waste heat into electricity.
Inside fossil-fuel and nuclear-power plants, as well as in cars and trucks, the lion's share of energy in fuel is wasted as heat rather than converted into electricity or mechanical power. But the search for a practical material that can convert at least some of this waste heat into electricity has been long and frustrating.
