Thermodynamic solars: a new italian technology

"Encouraging news in the renewable energy come from solar thermal industry that, in 2009, has experienced considerable growth and that seems destined to play an even more important in coming years. The U.S., in fact, intend to achieve by 2020 the technology for new power plants with a total capacity of 10.3 GW of power.
Also Italy is taking decisive steps in this field, as evidenced by the recent birth of a company called Archimedes Solar Energy, which produces the key component of solar thermal power plants, pipes receptors, according to a new technology patented by ENEA." World of Solar Thermal - Solar Thermal Energy Daily News, Events, Companies, Products, Jobs and more - Thermodynamic solars: a new italian technology

Why the name "Archimedes"? Let us remember what the 2nd century AD author Lucian wrote about.
"During the Siege of Syracuse (c.214–212 BC), Archimedes destroyed enemy ships with fire. Centuries later, Anthemius of Tralles mentions burning-glasses as Archimedes' weapon. The device, sometimes called the "Archimedes heat ray", was used to focus sunlight onto approaching ships, causing them to catch fire. This purported weapon has been the subject of ongoing debate about its credibility since the Renaissance. René Descartes rejected it as false, while modern researchers have attempted to recreate the effect using only the means that would have been available to Archimedes. It has been suggested that a large array of highly polished bronze or copper shields acting as mirrors could have been employed to focus sunlight onto a ship. This would have used the principle of the parabolic reflector in a manner similar to a solar furnace." More  wiki
