Researchers discover source for generating 'green' electricity

University of Minnesota engineering researchers in the College of Science and Engineering have recently discovered a new alloy material that converts heat directly into electricity. This revolutionary energy conversion method ...

Quantum thermal transistor can control heat currents

(Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in ...

GE and Hitachi want to use nuclear waste as a fuel

(PhysOrg.com) -- One of the world's biggest providers of nuclear reactors, GE Hitachi Nuclear Energy (a joint venture of General Electric and Hitachi), wants to reprocess nuclear waste for use as a fuel in advanced nuclear ...

Turning desalination waste into a useful resource

The rapidly growing desalination industry produces water for drinking and for agriculture in the world's arid coastal regions. But it leaves behind as a waste product a lot of highly concentrated brine, which is usually disposed ...

Green Ideas: Making Concrete from Rice

(PhysOrg.com) -- Concrete accounts for about 5% of all human-related CO2 emissions. The fact that we use so much cement in building could mean that the issue becomes even more pronounced in the future. But what if there was ...

New track for converting waste heat to electricity

Huge amounts of energy are lost every day in the form of waste heat. Now an interdisciplinary project at Chalmers has found that a special class of material – high-entropy alloys – can open the door to efficient heat ...
