Temperature differences give rise to electricity

More than half of today's energy consumption is squandered in useless waste heat, such as the heat from refrigerators and all sorts of gadgets and the heat from factories and power plants. The energy losses are even greater ...

Researchers discover new material to produce clean energy

Researchers at the University of Houston have created a new thermoelectric material, intended to generate electric power from waste heat - from a vehicle tailpipe, for example, or an industrial smokestack - with greater efficiency ...

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 ...

Storage of nuclear waste a 'global crisis': report

Nuclear waste is piling up around the world even as countries struggle to dispose of spent fuel that will remain highly toxic for many thousands of years, Greenpeace detailed in a report Wednesday.

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 ...

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 ...

Recycling in the US is broken. How do we fix it?

Recycling in the U.S. is broken. In 1960, Americans generated 2.68 pounds of garbage per day; by 2017, it had grown to an average of 4.51 pounds. And while many Americans dutifully put items into their recycling bins, much ...
