Sandia's Low-Cost Air Monitors Sniff Out Emissions
"The U.S. Department of Energy’s Sandia National Laboratories has developed a new atmospheric sampling device that is said to be smaller, lighter, less expensive and yet more accurate for taking the air samples that are used to calculate computerized climate models."

Algae-Powered Street Lamps Suck Up C02
"The lamps are really more like massive tanks filled with water and algae. During the day, the algae feed on sunlight and C02 in the air and the resulting energy is stored in batteries connected to the tank. The stored energy is then used to power the lights at night."

Electricity From Liquid Fuel? UCLA Researchers Say Yes
"Researchers at UCLA say they have come up with a method for converting electrical energy into a liquid fuel, in a development that could lead to regular petrol cars being powered by electricity."

New York City Energy Map Tool Tells Tales
"The tool makes use of ZIP code-level energy consumption data to estimate the average annual energy use for every tax lot at practically the level of the building throughout the entire city — a gargantuan feat, accomplished by first building a map using data gathered by the Mayor’s Office of Long-Term Planning and Sustainability for electricity, natural gas, steam and fuel oil usage, then estimating individual property energy use based on floor area and function."

Solar Suitcase Provides Light, Power During Emergencies
"What first responders need is an easy-to-use power generation unit that’s both portable and reliable. And that’s exactly what the folks at We Care Solar seem to have created with their innovative solar suitcase."
