MS ''Tûranor PlanetSolar'', known under the project name ''PlanetSolar'', is the largest solar-powered boat in the world The vessel was designed by LOMOcean Design, built by Knierim Yachtbau in Kiel, Germany, and launched on 31 March 2010. In May 2012, it became the first solar electric vehicle ever to circumnavigate the globe. ==Technical characteristics== The 31-meter boat is covered by 537 square meters of solar panels rated at 93 kW, which in turn connect to one of the two electric motors in each hull.〔 There are 8.5 tons of lithium-ion batteries in the ship's two hulls. The boat's shape allows it to reach speeds of up to 14 knots. The hull was model tested in wind tunnels and was tank tested to determine its hydrodynamics and aerodynamics. The boat was designed to be used as a luxury yacht after the record attempt was finished. It is currently being used as a floating marine research laboratory by Geneva University. The boat is registered in Switzerland and was financed by a German entrepreneur. Construction cost was € 12.5 million. The name ''Tûranor'', derived from J.R.R. Tolkien's novel The Lord of the Rings, translates to "The Power of the Sun". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tûranor PlanetSolar」の詳細全文を読む スポンサード リンク
