Algae's solar electrons hijacked to steal power - tech - 17 March 2010 - New Scientist
Algae's solar electrons hijacked to steal power - tech - 17 March 2010 - New Scientist: "May lead to a more efficient exploitation of photosynthesis to power machines: with biofuels we are already converting solar power into a form that engines can use, but almost three-quarters of the sunlight energy absorbed by the organisms is lost before it can be turned into the sugars or starches used to make biofuels."

Observations: Storing megawatts: Liquid-metal batteries and electricity
Observations: Storing megawatts: Liquid-metal batteries and electricity: "Making aluminum requires a lot of electricity. That's because the metal bonds tightly to oxygen and it takes a lot of energy to break that bond. In essence, the process of making aluminum is a giant battery with the silvery metal being reduced to purity at the cathode while oxygen bonds with the carbon anode to make, you guessed it, CO2. It takes roughly 15 kilowatt-hours of electricity to make just one kilogram of aluminum via electrolysis."

Will Agribusiness Be A Growth Market for Solar? : Greentech Media
Will Agribusiness Be A Growth Market for Solar? : Greentech Media: "Produce and solar, it turns out, have a lot in common.
Agribusiness has a number of characteristics that could make it a prime sub-market in the solar business, according to Mike Miskovsky, General Manager of Canadian Solar's U.S. operations."

Nanotube cuff is 'solar cell' for exhaust pipes - tech - 09 March 2010 - New Scientist
Nanotube cuff is 'solar cell' for exhaust pipes - tech - 09 March 2010 - New Scientist: "The hot gases passing through a vehicle's exhaust could be tapped to generate power, using 'cuffs' made from a new carbon-nanotube-based material. The 'thermocell' produces electricity at a similar cost per watt as commercial solar cells."

Where Will the U.S. Get Its Electricity in 2034?: Scientific American
Where Will the U.S. Get Its Electricity in 2034?: Scientific American: "Cleaner coal, nuclear, solar, wind: these are some of the options for power generation to feed the U.S.'s electric power requirements. That need is expected to grow by 30 percent during the next 25 years, according to the Energy Information Administration, even with a slew of energy-efficiency measures and improvements to the grid infrastructure that delivers the electricity. But the primary source of electricity in 2034, according to a new projection from consulting firm Black & Veatch, will be natural gas. It is the fossil fuel with the least greenhouse gas impact on the atmosphere—burning it releases 43 percent less CO2 than burning coal—and looks set to increase its share of the electricity market, even with looming regulations to restrain climate-changing emissions. And there's this boost, too: new, vast reserves of natural gas found in places like the Marcellus Shale Formation, which stretches from West Virginia to New York State."
