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 a solar concentrator low tech. Exit couteuses parabolas and their polished mirrors at gold price. Put in the common materials, fabricated in big series.

An aluminium structure, bent plates of mirror but bottom-of-the-line — quality room of baths, a device of chase, and a metal conduit in the form of spool placdé in the home, and the turn is played. This “flat solar energy”, as say the English speakers, gives a factor of solar concentration of one thousand, for an only 13-square metre surface. It would be almost possible to imagine it in gardens to heat houses and to produce electricity if there were not risks: with a factor of concentration of one thousand, all that crosses near the home is instantly ignited SHOULD PUT It offer a gallery of pictures of the apparatus.

According to concepteurs, on nice day, the concentrator can give 10 kilowatts of heat and, if it is equipped with a generator of current, 3,5 kW electrical. Of what to feed, for example, techniques of food manufacture, or heating of buildings. The inventors put forward the weak cost of components and the simplicity of assemblage. Without giving more precision, naturally.
