Is India ready for CTL fuels? (editorial)

Faced with high oil prices and increasing oil imports to meet the country's rising demand for transportation fuels, there is now a perception that India's energy security is threatened. In addition to securing overseas oil fields, alternative options include biomass-based fuels and coal-to-liquid (CTL) fuels. While the production of biodiesel …

Alternative energy fuels long-term opportunity

High oil prices, firm demand and climate change issues are working in favour of alternative energy sector. As oil prices continue to hover around record highs and climate change problems rise up government agendas, the case for investing in alternative energy is becoming more compelling. "Investors have been shunning mainstream …

Cheaper natural gas from oilfields

some microbes have been breaking down petroleum into methane deep within the earth for ages. But we do not know the bacteria or how they do it. A recent study has revealed the answers, with scientists producing methane from petroleum in the laboratory by feeding these microbes. Over millions of …

twin of the sun: Astronomers have found the Sun's long-lost twin. The star HIP 56948, considered to be the best solar twin, is about 200 light-years away. The mid-sized star is one of many in the Draco constellation and may be a billion years older than the middle-aged Sun

Effect of edta, potassium ferrocyanide and sodium potassium tartarate on production of ethanol from jaggery

Effect of chelating agents, which include EDTA, Potassium Ferrocyanide and Sodium Potassium tartarate on ethanol production from jaggery using Saccharomyces cerevisiae NCIM 3241, was tested. It was found that addition of chelating agents along with inoculum gave better results and among the three chelating agents EDTA resulted in 72g11 of …

Can coal be clean?

Currently, over a quarter of the world’s primary energy supply comes from coal. Since the rich world has already created its coal infrastructure, the increased use of coal in China and India is now under scrutiny. In 1980, rich countries used over 65 per cent of the world’s coal; in …

Nothing new

Is it possible for the world to reinvent its energy systems? If it has to reduce its emissions by over 80 per cent, the only option it has is to make the transition towards zero-carbon technologies as quickly as possible. But this is not happening. The January 2007 report of …

Heat from the street

Energy: A clever new system uses asphalted roads, rather than solar panels, to collect solar energy in order to heat an office building SOMETIMES the simplest ideas are the best. To absorb heat from the sun efficiently you need large, flat, black surfaces. One way to do that is to …

Nanowire as solar cell

a new nanowire promises to revolutionalize the world of nanotechnology. Developed by scientists at Harvard University, the wire, which is a fraction of the width of human hair, will function as a solar cell, generating power for its own use, and other nanodevices. Scientists say the nanowire is more efficient …

Time to ditch Kyoto
