Bharat Heavy Electricals Limited (BHEL) recently developed a hightech railway locomotive compatible both in the AC and DC modes. The only one of its kind in India, the locomotive has a capacity of 5,000 horsepowers (hp) in the AC mode and 4,600 hp in the DC mode. Said T S …
LIGHT-EMITTING diodes (LEDs) have come a long way since they became known to the public 20 years ago with the introduction of the first digital wrist watches. Now red LEDs can be used in traffic lights to reduce the energy consumption of traffic signals by 60 per cent and to …
THE future of nuclear pow~r worldwide appearS to be hanging in balance. Its prospects looked rosy 20 years ago when steep rise in oil prices compelled the Western nations to face the dreadful possibility of a serious and lasting energy shortage. Yet at that time, nuclear energy was not being …
A 'POWER tower', 7,000 metres-high, which could produce pollution-free energy from the North Sea, is being proposed by researchers in the Netherlands. Its proponents claim that the tower coUld gener- ate nearly twice as much electricity as Drax, Britain's largest power station, by harnessing the same natural ~ystem that cauSes …
A new lighting control equipment based on daylight sensors is being tested in eight experimental offices in Trondheim, Norway, by the Norwegian Electric Power Research Institute. One of the two control systems in the equipment switches off lights automatically when day- light exceeds a specific limit, and switches them on …
The largest methane gas collection programme in the world has begun at a huge sewage treatment plant at Werribee near Melbourne, Australia. The plant is expected to generate 800 KW of electricity. Sewage at the plant is treated in ponds in a two- phased process. The first is by an …
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 …
FROM this year, Chicago (us), will start using three prototype buses powered by fuel cells of a type which were aban- doned after the Gemini space pro- gramme in 1996, but resurrected by Ballard Power Systems of Vancouver - a small Canadian firm of engineers. The only thing coming out …
A NEWLY invented light bulb promises to offer significant energy savings and better light to future users worldwide, according to the US department of energy (DOE). The bulb is filled with inert gas and a small amount of sulphur that is bombarded by microwaves to produce luminescence. The Washington Post …
A NEW electronic device, called thyristor-controlled series compensator (TCSC), may "revolutionise the way electricity is delivered to customers globally". The first such system was recently dedicated in the US to the Bonneville Power Administration's (BPA) Slatt substation in Antral Oregon. According to a report in (Power Engineering International, Vol 2, …
SINCE July last year, the municipal garbage dump at Gladokvarn, outside Stockholm, has been yielding gas at the rate of 22,000 in per day from gas wells up to 20 in deep. The gas is carried via a 13 km-long pipeline to a 5 mw heating plant which, in turn, …
Researchers from the Dehradun- based Indian Institute of Petroleum have developed a new technology for multi-fuel burner for furnaces capable of saving 15 to 25 per cent energy over the existing burners. This is based on a new concept called low air pressure (LAP) film burner and can use more …
Heatermeals of Cincinnati, USA, has made it possible to have a warm meal anywhere and anytime you wish. Details on the new device (Newsweek, September 25, 1995) states: "remove the food container from the packing carton, pour two ounces of water on its food-heating pad - this starts a chemical …
Lumatec of Austin, Texas, USA, is selling a wafer-thin flashlight that is small enough to be slipped into a shirt pocket, wallet or calendar/ organiser. Dubbed Flashcard, it features a super bright krypton bulb, a dome-shaped on/off switch, and a mercury-free battery. This flat light device is water-proof to a …
LET us accept the general consensus of scientists that global warming is happening, that it is caused largely by carbon dioxide released by burning fossil fuels, and that it cannot be reversed without a reduction in the use of fossil fuels. Following on from Rio and more recently Berlin, most …
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 …
NATURAL gas is formed under the earth's surface when organic debris, under conditions of high temperature and pressure breaks down into methane and other smaller hydrocarbon molecules. Similar conditions simulated in the laboratory did not yield the requisite percentage of methane in the end product. Whereas natural gas contains 80 …
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 …
Ice that burns could provide immense energy A! future, if only scientists co figure out how to g ground. Gas hydrate, mainly fro methane, may contain twicel much energy as all fossil fuels P together. But it exists several hundred metres below the f1 and fizzes away when brought the …
'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 …
