Cheap, solar-generated electricity has now become a reality with the successful testing of a prototype solar device at the Weizmann Institute of Science, Israel. It produces sufficient hot air from the sun's rays to drive the turbines of a 50 kw power station. The funnel-shaped device focuses the energy through …
Martin E Nix, an engineer from Seattle, US, who holds several patents for solar powered inventions, has devised a way of turning old refrigerators into greenhouses. The condenser, compressor and the motor are removed first; then a hole is cut at the top for a skylight and a solar-powered fan. …
Scientists from the Council for Scientific and Industrial Research Organisation and Pacific Power, Australia, have produced a synthesis of carbon monoxide and hydrogen by combining methane, carbon dioxide and the sunlight, which makes it possible to store and transport solar energy. When the synthesised gas is changed back into carbon …
A solar-powered water pasteurising device called Solsaver, designed by John Grandinetti, president of Grand Solar Incorporated of Hawaii, USA, may bring an end to people falling prey to water-borne diseases (World Watch, VoJ8, No 5). The Solsaver uses thermal action to move the water which flows through copper tubing into …
Scientists working at the Fraunhofer Institute for Building Physics in Germany, have devised an 'intelligent window' which can automatically modulate the amount of sunlight entering a room. Just as sunglasses block light, the window's glass surface has a coating which is transparent at cool temperatures but becomes opaque when the …
Viruses pose a great threat to agriculture. An effective method for controlling the menace is raising plantlets by in vitro propagation in expensive greenhouses which require artificial lighting. Now, scientists at the Institute of Plant Research and Biotechnology (IPRB) in Cuba, have invent- ed a method that does away with …
HERE is an offer that makes you stop and think. Zurich's local electricity office, Elektrizitatswerk der Stadt Zurich (Fwz), recently sent around a circular offering 3,500 of its customers the opportunity to buy power at us $1.30 per kilowatt-hour instead of the normal us $0.13. Why would anyone want to …
Canon USA, New York, is intro ing the world's first fully autorr 35-mm solar-powered camera, Sure Shot Del Sol, The cam weighing about 28 grams, designed to lie flat and has a s panel mounted on the lens cc The camera cim be stuffed in a p, et and can …
'Smart' solar panels have fina been developed by researchers of Albert Ludwigs University, Freibi and Fraunhofer Institute for So Energy Systems, Lauenforde, bw in Germany. The material used - polymer blend of polypropyh oxide and a copolymer containi styrene and 2-hydroxyethyl met] crylate - allows the solar panels change from …
The inability to produce cheap and efficient photovoltaic cefls that convert solar energy into electricity has, till now, hamstrung solar power generation, Scientists have -xperi- mented with alternatives to silicon (used for photovoltaics) like organic polymers, which, while being cheaper and easier to process, are not effective enough. Now 2 …
Designed to preserve essential and vaccines in remote villalps I ing electrical power, a solar rdri ator has been developed by research and development wim Bharat Heavy Electricals Lisni Hyderabad, under the World Hs Organization specifications. The solar refrigerator is di ent from a conventional refriger in that it is …
An Indian Institute of TechnoN Delhi, researcher has devised a, to produce potable water fi impure water using solar ent efficiently. The device, a solar a produces 20 per cent more w than other stills and gives 3 1 litres of clean water per sq metre day, reports Science For …
The government of the Netherlands has pledged to churn out the funds for producing solar energy in Bhutan. The deal is a part of the bilateral sustainable development agreement signed between the two countries in March 1994, which envisages cooperation in biodiversity, energy, culture and human resources. So far US …
Solar power has started replacing conventional power in some areas even as researchers persevere in developing more efficient solar cells to tap this clean source of almost limitless energy (New Scientist, Vols 145, 146, Nos 1969, 1974). In Germany, bus stops, shelters, parking ticket machines and speed warning signs powered …
From environment-friendly cars, researchers move on to an environment-friendly aircraft, which derives all its energy from sunlight. Developed by a team of scientists from AcroVironment, an engineering company based in Simi Valley, California, this new version of Pathfinder, a 18 1 -kg acroplane, is to begin test flights soon (Nature, …
One of the oldest games that we have played has been agriculture, where man has manipulated nature to his own advantage for over 5,000 years. But the game has hardly begun. Agriculture is the latest of the applied molecular sciences, where all the powers of the chemist and biologist will …
An American company, Solar Power International, Inc. has developed a solar lawn mower that is pollution- free. A conventional gasoline-powered lawn mower, on the other hand, causies more pollution in half an hour than a car driven 300 km (Solar Today, Vol 9, No 2). The solar mower uses photovoltaic …
The American industry is pushing for a new lease of life to solar thermal power technology. As a first step in this direction, Solar One, a solar thermal power project located in California is being renovated (Solar Today, Vol 9, No 2). The Luz International Company which set up and …
The US firm, Amoco-Enron Solar Power Development Corp of Houston, Texas, has proposed a solar photovoltaic (SPV) power plant in Rajasthan's Thar desert. The 150 mw project is estimated to cost Rs 1,000 crore (Solar Today, Vol 9, No 1). This proposal comes in the wake of a breakthrough in …
IF GREEN plants can capture 95 per cent of the total energy from sunlight through the process of photosynthesis, why can't the solar photo-voltaic cells (SPV)? The best SPVS are able to absorb only 25 per cent of the solar energy available on the surface of the Earth -- a …
