The solar cells, this walks since the sixties. But because of their weak output and of their cost price, to cross the threshold of competitiveness returns to climb up an impassable mountain. The American Nanosolar had opened a way in producer of cells hundred slimmer times. Researchers of the Massachusetts Institute of technology have [...]
The European Union decided to attack the electrical consumption of apparatus household appliance and electronics in mode stays up. According to the Committee of Brussels, she would represent an electrical consumption of 50 TWH, the upper to that of a country as Denmark. A plan of regulations aiming at reducing this 75 % wasting before 2020 was approved [...]
In the United States, the stories of start-up begin often just like that. Teachers, idea, and motivated students. It is just like that that Raw-Solar, the young shoot was born who pretends to revolutionise the solar production of heat with high temperature. A direct emanation of jobs driven by the students in the Massachusetts Institute of Technology, who created [...]
Solar energy has the wind in poop in the United States. And it is not the study published by the Solar Catalyst Group and Klin Edge who will deny him. The experts think that the United States could draw 10 % of their electricity of the sun in 2025, by combining the photovoltaic installations and the solar power stations with concentration.
Electrical [...] power
Undoubtedly, the dazzling increase in the barrel of oil dopes the inventors. In Japan, the Genepax business company, a young born shoot two years ago with less than three hundred thousand euro of capital, informed this week that she would soon introduce the details of its technology of water motor. On June 12th, [...]

A wind this floats tremendously. It is anyway for what hope German Siemens and Norwegian StatoilHydro, that is going to instal a floating turbine, by two hundred metres of bottom, next year, off Norway.
The turbine, of a maximum power of 2,3 megawatts, will be fixed to sixty-five metres above the water on a buoy [...]
Reduce by a factor 10 the number of cells used in the photovoltaic concentrators (CPV), here is the small revolution offered by the engineers of IBM. Secret: link photovoltaic technology and computer technology. The principle of functioning of CPV is simple: the more light is concentrated on the cell, the more produced electrical power is important. There [...]
The Earth makes us the blow of breakdown And it risks costing a lot, because the oil is a very profitable energy. A litre of this precious liquid would be equivalent in two days by working man The industry of the plastic gets ready to face up the rarefaction of the black gold. Length: 104’. © Science Frontières.
