Ever on the lookout for a marketing opportunity and bucking the status quo, Richard Branson, head honcho of the Virgin group, has announced his next likely venture: Renewable Jet Juice. "We are looking for alternative fuel sources. We are going to start building cellulosic ethanol plants (to make) fuel that is derived from the waste product of the plant," he said. "It is 100 per cent environmentally friendly and I believe it's the future of fuel, and over the next 20 or 30 years I think it actually will replace the conventional fuel that you get out of the ground." Currently there are four airlines under the Virgin banner, which gives a fleet of close to 100 aircraft, using about 700 million gallons (2,650 million litres) of fuel annually. So one can understand why Richard might be keen to “replace some or all of that (with ethanol)" in the next handful or so years. Virgin do have some other environmental initiatives on the go, but most are just the usual good governance, like recycling office paper and toner cartridges. However their British trains do use 'reverse thrust' traction motors to brake, which apparenting generates electricity for national grid supply, as a side benefit. More eco Virgin bits here.
