There was in interesting segment on biofuel on Jummys farming or
whatever it was called the other night. Some bloke was farming Willow
trees to be burnt for power at Drax (so they can reduce their net CO2
output). He had a huge barn full of wood chippings he'd made, couple
of hundred tons I believe. Guess how long it kept Drax going for? 2
flippin hours! And that was the guys whole crop for the year!
