The US Department of Energy (DOE) will support the construction of three small nuclear reactors at its Savannah River Site in South Carolina. The reactors are designed to generate heat and electricity for use at remote facilities such as mines, oil fields or isolated communities. The three companies involved are Gen4 Energy (formerly Hyperion), Holtec International and NuScale Power.
ScienceDaily (Jan. 31, 2011) — Physicists are closer than ever to finding the source of the Universe's mysterious dark matter, following a better than expected year of research at the Compact Muon Solenoid particle detector, part of the Large Hadron Collider at CERN in Geneva.
When it comes to dissipating energy in the atmosphere, the humble raindrop punches way above its weight. Researchers in the US have shown that the energy lost as heat by falling liquid water and ice particles is on par with the energy that the wind loses to friction. The team suggests that with the increasing precipitation expected as a result of global warming, the energy sunk into rainfall could reduce the amount available to generate winds.
