Article: http://www.environmentportal.in/files/biomass.pdf plant organic matter or biomass transport fuel Like petrol (gasoline), an ideal biofuel should drop into today’s infrastructure and carry enough juice to get any vehicle where it’s going. Describing the disadvantages of ethanol is done well: a litre of ethanol takes a car only about 70% as far as a litre of petrol, and ethanol cannot provide enough power for heavy trucks or aircraft Description of how a hydrocarbon generates energy: he carbon–hydrogen bonds are where the useful energy is stored; breaking these bonds through combustion releases energy How scientific processes are explained easily: The water has to be boiled off, which means using more energy to produce the fuel. But butanol and water don’t mix, so they can be separated by less energy-intensive processes. Good summarization: “Electricity for the light vehicles, biomass for the heavies, and we’re energy independent in two decades,” he says. Liao,
