The application, based on a letter petition, a resident of village Kunidhar, tehsil Bhikiasen, Almora had made a complaint about indiscriminate felling of Chir and Banj …
eco-friendly truck: J Sainsbury Plc of the uk has developed the world's first solar photovoltaic-cooled food distribution truckthat aims at increasing the commercial use of the eco-friendly solar energy and reducing operating costs. Ample power for the refrigeration unit is generated by solar panels mounted on the trailer's roof. This …
A delegation from photovoltaics (PV) organisations of India visited Japan to participate in a PV seminar to discuss PV policy, technology development, applications and industry status in the two countries, as well as identify areas of cooperation. Japan and India are the world's second and third largest producers of solar …
Germany is going to promote installation of photovoltaic (PV) equipment on 100,000 roofs and facades throughout the country. In terms of budget and investment volume, this is the largest market scheme for PV technology ever launched, aiming to create a total energy generating capacity of 300 MW within just three …
a heliostat is being developed that increases the output of photovoltaic (pv) modules by more than 450 per cent. Colin Johnson and his colleagues at HelioEnergy of Whangarei, New Zealand, have designed the machine that uses a clockwork mechanism to turn a mirror to focus the Sun's light in fixed …
who needs a roof? Cover your house with solar cells instead. The idea may seem weird, but this is exactly what the architects of a us-based engineering and architectural firm have done while designing William and Deborah Lord's home in Kennebunkport, Maine, us. Now, when the morning sun breaks over …
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 …
MANY villages in developing countries have partial or virtually no access to electricitv because of unreliable power supply frorn existing grids and prohibitive costs of laying conventional power- lines to remote areas. In addition, the fuel used to power electric generators is expensive. Under such circumstances, can modern health care …
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 …
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 …
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 …
A new solar cell design could slash the cost of producing solar electricity by at least 80 per cent, claim researchers at the University of South Wales in Australia (Environmental Science & Technology, Vol 28, No 8). Conventional cells use expensive high quality silicon 400 microns thick but the metal …
PLANTS have been doing it for millions of years now, but it is only now that scientists are tasting success in trapping the sun"s energy in chemicals and then using it to produce fuels. Plants and some bacteria harness solar energy through photosynthesis. But scientists trying to tap almost unlimited …
FOR ONCE, Indians can look forward to the sun doing the out-of-character job of cooling them. A new device -- a "suncap fan" that brings visions of a whirligig attached to a dunce"s cap -- that might soon hit the country"s overheated cricket stands will be powered by solar photovoltaic …
LIFE WOULD not be possible without the light and heat received from the sun. For all the energy that we consume on earth -- whether in the form of biomass or oil -- the ultimate source is the radiation from this fairly ordinary star in the Milky Way galaxy. The …
JAPAN'S Canon company, world-famous for its cameras, has adapted a technique used in making photocopiers to produce cheaper and more efficient solar cells. The technique involves sandwiching amorphous silicon between two layers of amorphous silicon germanium (New Scientist, Vol 137, No 1865). Silicon and germanium are semiconductors, which means while …
• A RS 4.5-crore, 100-kw solar photovoltaic power plant -- Asia's largest -- is to be commissioned by Prime Minister P V Narasimha Rao in May 1993 at Kalyanpur village in Aligarh district. • A Rs 4,000-crore, 100-mw tidal wave power project in the Gulf of Kutch is being reviewed. …
With the resource crunch persisting, won't you find it difficult to raise funds for the revised target of 2,000 mw for power generation from non-conventional energy in the Eighth Plan ? Funds will be mobilised through private sector investments, loans from financial institutions and assistance from international agencies in addition …
Mini-micro hydel: Indian technologists developed mini-hydel systems more than 100 years ago, but in the post-Independence emphasis on the new "temples of modern India" -- huge dams and power stations -- mini-micro hydel systems were neglected. In 1989, however, hydro projects below 3 mw were transferred from the power ministry …
SOLAR cells used to tap energy from the sun are made up of photovoltaic substances such as silicon which, when combined with suitable additives and exposed to sunlight, produce electricity. Extracting crystalline silicon from the compounds in which it is found is highly energy-intensive and the element itself accounts for …
