Scientists demonstrate high-efficiency quantum dot solar cells

Research shows newly developed solar powered cells may soon outperform conventional photovoltaic technology. Scientists from the National Renewable Energy Laboratory (NREL) have demonstrated the first solar cell with external ...

Skin hair skims heat off elephants

Body hair in mammals is typically thought to have evolved to keep us warm in colder prehistoric times, but a new study suggests that it may do the opposite, at least in elephants. Epidermal hair may have evolved to help the ...

Triton: A subsurface ocean?

Neptune's largest moon Triton is most likely a captured Kuiper Belt Object. The capture of icy Triton and the subsequent taming of its orbit likely led to the formation of a subsurface ocean through tidal heating. New research ...

Radar gun catches predator shredding turbulence in fusion plasma

Recent experiments carried out at the DIII-D tokamak in San Diego have allowed scientists to observe how fusion plasmas spontaneously turn off the plasma turbulence responsible for most of the heat loss in plasmas confined ...

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 ...

Space sensor helps produce 'greener' glass

What has making glass in common with space exploration? The special technology to measure oxygen atoms outside space vehicles is now being used in the glass industry to produce super-efficient energy-saving windows.

1930s home goes green

A 1930s house built in 2008 is about to undergo the first of three energy efficiency upgrades which will ultimately convert an energy inefficient house into a zero carbon home designed to meet the Government's 2016 CO2 targets ...
