They used Fresnel lenses situated 10 cm apart from stacked layers of solar cells. The metamorphic triple-junction solar cells consist of gallium indium phosphide, gallium indium arsenide and germanium semiconductors. The efficiency of these cells is dazzling: 41.1 percent - higher than ever before. The two scientists even for the 2010 Joseph von Fraunhofer Prize.
The electric car that caught most of the attention from the press lately is Nissan Leaf, presented as being the first mass-market electric car. The Netherlands will be the country that Nissan is going to sell it first, probably because of the country's green orientation. The unveiling will take place in December this year.
Some solar energy adopters wish to use their solar panels in the classic manner - installed on a roof or in their backyard. Still, there are situations where installing a flat solar panel is near to impossible, due to space limitations in places like corporate buildings or where aesthetics matters.
Hydrogen, the cleanest energy storage in the Universe, is most of the time associated with high costs, although it is extracted from water, which is the cheapest yet the most precious element to life. Extracting hydrogen from water is done through a method called electrolysis, but doing electrolysis efficiently requires the usage of catalysts such as platinum, which is very expensive.
A team of engineers from MIT have designed fuel-efficient aircraft that are expected to reduce the emission of nitrogen oxides and unlike conventional models, to consume 70 percent less fuel.
estir Co., an in-company venture of Panasonic led by Teruyuki Akazawa, thought that it would make a good business reusing the otherwise wasted heat from Panasonic's plants, and reimplemented Stirling engines, seeking to make them more efficient than ever.
The Japanese giant company, Mitsubishi Electric, recently launched a "smart grid" pilot project that according to the company will be able to boost the stability of the electricity supplied from weather-dependent sources such as wind and solar power.
I admit I use to buy bottled water when I get thirsty and there's no nearby water source available, but a kiosk selling stuff. Where do all water bottles get to, what is this huge industry doing with all the garbage it leaves behind?
The National Cheng Kung University in Taiwan has developed Asia's first unmanned aerial vehicle (UAV) called the Grey-Faced Buzzard. The green-powered UAV that made its maiden flight in Southern Taiwan is powered by lithium batteries and fuel cell.
Student scientists at Northeastern University have designed an apparatus capable to transform waste plastic into an alternative fuel without releasing harmful emissions.
