Electrical utility transformers that use oil as an insulating barrier between the high and low voltage wire windings often fail because moisture and explosive gases build up in the oil, forming a pathway for a sudden, dangerous electric arc between the windings. Larson-Davis Inc of Provo, Utah, us , have …
With its total peatland extending over 26 million ha, Indonesia has the world's fourth largest reserves of peat. This Indonesian peat has a calorific value of 22 mega joules per kg. Experts say that at an average depth of six metres, the peat produced from an area of this size …
Researchers at Northeastern University of Boston, Massachusetts, us , have developed cartridges made of graphite nanofibres, which, they claim, can store 10 times more compressed hydrogen at room temperature than conventional tanks. They claim that these cartridges will enable hydrogen-powered cars to travel upto 8,000 km. The nanofibres, which are …
ANIL K RAJVANSHI can India's dependence on imported fuels to meet her energy needs be reduced? The answer seems to lie in the creation of energy self-sufficient talukas (administrative blocks comprising about 100 villages) through biomass-based systems of energy generation, as suggested by a recent study by the Nimbkar Agricultural …
ethyl alcohol or ethanol, which is produced by the fermentation and distillation of sugar derived directly from crops like molasses and from agricultural residues, can be used as a premium liquid fuel to supplement the use of petroleum-based fuels in vehicles. A blend of 20 per cent ethanol and 80 …

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 …
Osram-Sylvania Inc of usa has unveiled a new kind of fluorescent lamp that promises to increase the life of fluorescent tubes three fold. The tubes can then glow for about 60,000 hours. The secret behind this is the use of magnetic-induction technology to generate light-producing electrons. This technology does away …
Trees contaminated by radioactivity from the 1986 Chernobyl disaster are to be burnt to produce electricity. Scientists from the us and Belarus are planning to construct a power plant fueled by timber from around the crippled reactor. Larry Baxter, a chemical engineer working in the area claims that more than …
saving electricity with energy-efficient compact fluorescent lamps (cfls) can cost as little as one-tenth of the investment needed to build new power plants that produce the same amount of energy, say scientists at the Lawrence Berkeley National Laboratory (lbnl) in California, us. In the us, where lighting in rural and …
access to conventional energy resources will soon become a problem in future since estimates suggest that global reserves will last 40 years. In contrast, coal may last another 240 years. Compared to petroleum and natural gas, coal is inferior, generates less energy when burnt and emits a greater volume of …
