Let There Be Light Essay examples -- Energy Transportation Papers

Let thither Be Light The solarise shines brightly over the rolling unripe hillsides on a beautiful summer day. Green leaf-covered trees wave softly in the breeze next to the road, soaking up the light. However, if you look closely, pip in the distance, you might catch a glimpse of some odd-looking vehicles access at a steady pace. As the pack zooms by, you cannot help just now notice the black panels covering each car. You curiously wonder what settle they serve, and why these automobiles left no smell of exhaust behind. Suddenly, you realize the contact It was right under your nose the whole time Just as the trees use sunlight to grow and reproduce, these solar powered cars convert the suns rays into energy that propels them onward. History In 1839, a French scientist named Edmond Becquerel experimented with electronics and erect that he could create a weak electric current utilise selenium, a light-sensitive metal that responded to the suns rays. Becquerel had discovered moving-picture showvoltaics (photo meaning light, voltaic meaning power), or the PV effect, which turned prohibited to be the key to harnessing solar energy and converting it into useful forms (Bellis 1). Although he had modest explanation for this phenomenon, his successors picked up the investigative process where he left off. In 1870, Heinrich Hertz researched and experimented with selenium, and produced a primitive light-to-electricity machine (1). As time progressed, scientists highly-developed newer and better solar energy converters using silicon, which had a much high efficiency than selenium. solar cells were first officially invented by Charles Fritts in 1883 (1). Fritts employ the selenium metal, which ... ... Cars Solar Energy and Photovoltaics. New York About, Inc., 2002. 23 Aug. 2002. History of the cosmos Solar Challenge.
