scientists feel that it is possible to trap solar power in outer space, beam it to the Earth, and convert it into electricity. With the help of latest techniques, they hope that solar energy could be delivered at prices equal to or even lower than ground-based alternatives without big environmental …
solar power, probably the most abundant natural resource in Rajasthan, is now being used to run fax machines, computers and telephones in Tilonia, Rajasthan. The solar power unit at the social work research centre in the model village generates electricity to meet the requirements of not only the centre, but …
According to the International Centre for Application of Solar Energy (CASE), the most economical energy system to meet rural energy needs is hybrid energy consisting of solar power, wind power and diesel. Five centres in India, four in Thailand and two in Malaysia have been identified by CASE to set …
An award-winning vehicle designed at London's South Bank University by engineering graduate Paul Chapp may provide an alternative to conventional mopeds and motor- cycles. The scooter's 12-volt battery receives a charge from the solar papel above the rear wheel, producing enough electricity on a bright day to give it a …
amid growing awareness of the need for environmental protection and energy conservation measures, consumer electronics firms in Japan are lining up to enter the market for solar-power generation systems. Manufacturers are especially targeting the market for residential solar-power generation systems, encouraged by the Japanese ministry of international trade and industry's …
The solar energy group of the Renewable Energy Research Centre, Vietnam, has designed an efficient solar water heater. The system consists of three collector-cum-storage tanks with a total capacity of 90 litres. Inside the tank, a metal plate is linked under the solar energy absorber surface. The water-heating mechanism in …
Malaysia's International Centre for Application of Solar Energy (case) has set up centres using hybrid energy, which consists of a combination of renewable sources
delegates and various experts from more than 100 countries attended the World Solar Summit, where 300 solar energy projects in 60 countries were identified despite the absence of money needed to ensure that they can be started. Also absent were the heads of states from the North, with whom lies …
The use of solar energy in the health sector has brought many dividends for African countries. The World Health Organization (who) had initiated a project 15 years ago for the application of solar energy for refrigeration of vaccines in remote areas with no other energy sources. Now, photovoltaic refrigerators are …
Akzo Nobel nv , a Dutch chemicals company, has been charged with stealing technology that makes solar energy cheap enough to compete with conventional electricity. A Dutch entrepreneur Peter van der Vleuten is planning to initiate legal action against the company alleging the theft. He had started a US $37 …
a new set of improved solar devices including the solar cooker, water heater, solar wax melter and solar drier has been developed by the Consortium of Rural Technologies ( cort ), a Delhi based voluntary group engaged in the development of appropriate technology for the villages. The existing devices are …
Now crops can be dried even during the night with the help of a solar dryer that can store heat in a special rock bed unit. The solar dryer consists of a solar collector, a rock bed heat storage unit, a drying chamber and a chimney. Part of the heat …
WEEDS and soil-borne pathogens pose a major threat to crops. Soil solarisation offers a cost-effective and non-chemical method of checking their growth. It is achieved by covering (mulching, tarping) the soil with transparent polyethylene during the hot season, thereby heating it and killing the pests. Soil solarisation is a recently …
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 …
