Solar power generation around the clock
A Californian company, SolarReserve, is developing a solar power system that can store seven hours’ worth of solar energy by focusing mirrors onto millions of gallons of molten salt, allowing the plant to provide electricity 24 hours a day.
Because the salt is cheap – made from potassium and sodium nitrate – it makes this solar plant competitive with fossil fuels. And of course it means at night there would be no need to which over to fossil fuels to generate electricity.
Signature of Antimatter Detected in Lightning
During two recent lightning storms, Fermi recorded gamma-ray emissions of a particular energy that could only have been produced by the decay of energetic positrons, the antimatter equivalent of electrons.
That doesn’t mean that if you’re struck by the special gamma rays you’ll be zapped into an alternate universe, but it will still really really hurt.
You may have heard already of the little town of Greensburg, Kansas. President Obama mentioned them in a speech on green energy and they were featured on an episode of Planet Green, How an Entire Town Leveled By a Tornado Is Rebuilding Green
