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, …
Brazilian researchers claim that they have been able to turn the oil of the African palm into a diesel substitute (Indian Forester, Vol 121,No4). This exceptional fuel possesses thermodynamic properties that are far superior to those of diesel fuel that is obtained from crude oil. It has been tested with …
AN AMERICAN company, Ultralife Batteries, has launched the world's first lightweight rechargeable battery made entirely from solid materials. The battery, launched a few weeks ago, can be recharged more than 1,000 times with only a tiny loss of capacity. In comparison, conventional batteries can be recharged a maximum of 200 …
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 …
GEOTHERMAL power is fast emerging as a significant source for electricity in several island nations, mainly in the Indian Ocean and the Pacific regions (The Royal Geographical Society Magazine, Vol 68, No 3). For instance, Indonesia is setting up 2 geothermal power plants each of 55 mw capacity on the …
In India, the Union ministry of non-conventional energy sources is pursuing various R&D; projects to harness the geothermal energy available. About 340 hot springs have been identified in the country, with temperatures varying from 60oC to 130oC. A 5kw experimental power plant is being operated at Manikaran in Himachal Pradesh. …
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 …
To conserve energy. the Tamil Nadu Electricity Board has introduced a range of distribution transformers called Amorphous Metal-core Distribution Transformers (AMDT). These transformers could reduce the "noload po"wer loss", or idling loss to 60 watts (w) as compared to 260 w by a conventional transformer. Says Tamil Nadu's minister for …
Negotiations are in the final stages between the Union ministry of nonconventional energy sources (MNES) and the Danish International Development Agency (DANIDA) to establish a Wind Energy Centre at Kayathar in Tamil Nadu.
