The pioneering scheme will see mountains of rubbish and leftovers converted into electricity through a process called anaerobic digestion... ...The Government plan to pump up to £500million into the project over the next five years. Environment Minister Phil Woolas said last night: "We're putting together a radical plan for a new source of electricity. This process means we can turn food waste, farm slurry and sewage into gases to make power. I hope it will be a great leap forward and could provide as much as six per cent of the power we use within the next five years."
The technology, developed by London-based The Facility, uses a flooring system that incorporates a matrix of hydraulic compression pads. The pressure of the footsteps on these pads pushes fluid through a micro-turbine and generates electricity. In 2007, a version of the technology that used the energy of passing trains to power a flood detector underwent successful trial at a bridge in the Midlands, Britain.
But BART officials said the higher cost is worth the investment to help combat global warming. And in the long run, they say, the bigger bill for solar may prove fiscally prudent if - as expected - the price of hydroelectric and fossil fuel-derived power continues to escalate. BART now pays an average of $95 per megawatt hour to run its trains, maintenance yards and stations, said Frank Schultz, who manages the transit agency's energy division. |
