- Solar Powered Air Conditioner Released
A company called GreenCore Air has released an air conditioner than can be powered by a single 170 watt solar panel. The GreenCore air conditioning unit can heat and cool a 600 square foot room. It runs on DC power, so there is no need to put an AC inverter between the solar panel and the air conditioner. This eliminates the power losses associated with converting AC to DC.
- Japan firms to work on solar-powered ship
TOKYO (Reuters) - The race to go green has taken to the high seas with two Japanese companies saying they would begin work on the world's first ship to have propulsion engines partially powered by solar energy.
Japan's biggest shipping line Nippon Yusen KK and Nippon Oil Corp said solar panels capable of generating 40 kilowatts of electricity would be placed on top of a 60,000 tonne car carrier to be used by Toyota Motor Corp.
- 'Anti-noise' silences wind turbines
If wind energy converters are located anywhere near a residential area, they must never become too noisy even in high winds. Most such power units try to go easy on their neighbors' ears, but even the most careful design cannot prevent noise from arising at times.
- A better way to make hydrogen from biofuels
Researchers here have found a way to convert ethanol and other biofuels into hydrogen very efficiently.
A new catalyst makes hydrogen from ethanol with 90 percent yield, at a workable temperature, and using inexpensive ingredients.
- Solar Collector Could Change Asphalt Roads Into Renewable Energy Source
Anyone who has walked barefoot across a parking lot on a hot summer day knows that blacktop is exceptionally good at soaking up the sun’s warmth. Now, a research team at Worcester Polytechnic Institute (WPI) has found a way to use that heat-soaking property for an alternative energy source.
- New bug ferments green fuel on the cheap
Genetically engineered bacteria could make cellulosic ethanol cheaper to manufacture, researchers report. The finding could unlock more energy from the waste products of farming and forestry.
