The nascent field of nanotechnology-enabled metallurgy has great potential. However, the role of eutectic alloys and the nature of alloy solidification in this field are still largely unknown. To demonstrate one of the promises of liquid metals in the field, we explore a model system of catalytically active Bi-Sn nano-alloys …
we are always the first to start. Invariably the last to finish. This is also, possibly, the story of renewables in the country. Way back in 1980, the government created the commission on additional sources of energy. In September 1982, the department of non-conventional energy sources was set up, and …
solar wasted sunshine POTENTIAL: India receives 5,000 trillion kilowatt hours per year of solar energy, estimated at 20 mw per sq km. INSTALLED: 0.385 million solar lanterns; 0.18 million home lighting systems; 41,000 street lighting systems, 4,204 water pumping systems; about 1.2 mw aggregate capacity of stand alone power plants, …
#1. Subsidies on fossil fuels (both covert and overt) make renewables uncompetitive. The biggest barrier to commercialisation of renewable energy is political. Politicians use subsidies as sops to retain power. The Electricity (Supply) Act, 1948, requires sebs to earn a minimum rate of return (ror) of 3 per cent on …
About 150 million tonnes of forestry waste and 350 million tonnes of agricultural residue are produced in India every year. However, a major portion of the wastes is not utilised. Scientists in India have devised pyrolysis method to convert biomass into charcoal briquettes that could benefit users and generate employment …
LANTANA CAMARA, a terror for cultivators, will finally see some use. Not only a menace in areas where the soil is fertile, the weed is equally at home in poor soils. Its seeds are disseminated widely by birds and have a high rate of germination. Moreover, Lantana is highly adaptable …
thanks to the Reserve Bank of India (rbi), the colour of money now will not only be green, but will actually have a green edge. rbi governor C Rangarajan inaugurated a system in December 1996, whereby unfit or mutilated notes were turned into bricquets to be used as fuel. Rangarajan …
INDIAN scientists, in collaboration with Dutch researchers, have developed the technology to convert agricultural residues -- like rice husk and groundnut shell -- into briquettes for use as an efficient, economical and a non-polluting fuel. The screw press technology for briquetting biomass compacts low-density agricultural residues into cylinders with a …
