Researchers at MIT and Stanford University have found a new alternative for low-temperature waste-heat conversion into electricity. The conditions needed are where temperature differences exist at less than 100º C (180ºF). Vast amounts of excess heat are generated by industrial processes and by electric power plants simply to be lost into the atmosphere and out [...]

Northwestern University (NU) scientists have discovered a surprising material that is the best in the world at converting waste heat to useful electricity. An interdisciplinary team led by inorganic chemist Mercouri G. Kanatzidis found the crystal form of the chemical compound tin selenide conducts heat so poorly through its lattice structure that it is the [...]

Physicists at the Harvard School of Engineering and Applied Sciences (SEAS) envision a device that would harvest energy from Earth’s infrared emissions into outer space.   The idea is essentially new, even as we live live on an enormous natural nuclear fission reactor in the earth’s core.  In the midst of a very cold winter the [...]

A Max Planck Institute for Solid State Research in Stuttgart, Germany has a group that can claim high efficiency thermionic conversion of heat energy.  The heat source could be light from the sun, heat from burned fossil fuels, nuclear or any of the fuel sources that yield energy with heat. Because of its thermionic energy’s [...]

In a completely unexpected finding, MIT researchers have discovered that tiny water droplets that form on a superhydrophobic surface, and then “jump” away from that surface, carry an electric charge. Initially the finding was that droplets could jump from a condenser surface – a component at the heart of most of the world’s electricity-generating power [...]
