Panasonic Corp. in collaboration with Sanyo Electric Co., plans to develop a lithium-ion storage cell for home use until 2011. “We’ll be the first to bring to the market a storage battery for home use, which can store sufficient electricity for about one week of use,” said Fumio Otsubo, president of Panasonic, in a recent [...]

Scientists at the Duke University have developed a novel approach that they believe can help generate electricity from nature’s motion. Energy harvesting is the process of converting one form of energy, such as motion, into another form of energy, in this case electricity. Strategies range from the development of massive wind farms to produce large [...]

Scientists at the Georgia Institute of Technology have developed a three-dimensional photovoltaic solar cell around an optical fibre. A new generation of hyper-flexible solar systems could be created thanks to this revolutionary research.

The company Sharp Corporation has developed the world’s highest solar cell conversion efficiency of 35.8% using a triple-junction compound solar cell. In comparison with silicon-based solar cells, the compound solar cell utilizes photo-absorption layers made from compounds consisting of two or more elements such as gallium and indium.

Two companies called Statkraft and Wetsus are trying to develop an alternative that provides low-cost renewable energy by harnessing energy from the sea water and clash of river.

Scientists from the Cornell University have created the basic element of a solar cell made from carbon nanotubes, that proves to be more much more efficient at transforming the energy from the sun into electricity.

Envion, a company from Washington D.C., uses a new technique, in which the plastic waste is heated using electricity and not at an open fire, to a very precise and careful temperature sequence, using infrared energy.

A “green” Jerusalem company called GreenSun has developed colorful solar panels that don’t need direct sunlight to work, capturing different parts of the sun’s light spectrum. The company claims that its highly-efficient solar panels will cost less than a dollar per watt to manufacture, in comparison with a conventional solar which cost more than $4 [...]

New Energy Technologies has developed an ultra-small solar cell that is capable to harvest artificial light which is in abundance in commercial skyscrapers and offices. New Energy’s solar cells installed in their transparent SolarWindow  generates electric energy by using the visible light in artificial fluorescent lighting typically installed in commercial buildings and offices .

The pumped hydro storage technology is already developed in a large scale. Riverbank Power, a new start-up founded by a former wind developer has a new idea. It wants to develop large-scale energy storage by using hills down onto the ground.
