Life gets so annoying that a good laugh helps ease things, so I'd like to thank Chuckles for this bit of lunacy -
"Since school corridors have existed, children have been told not to run down them. But a grammar school in Kent has turned the footfall of its pupils into a source of energy. Two dozen specially designed tiles, capable of harnessing kinetic energy and putting it back into the school’s system, have been placed along a corridor at Simon Langton Grammar School for Boys. The tiles, made from recycled lorry tyres, convert energy from pupils’ footsteps into sustainable energy using dynamos."
Seriously, I once spotted a Green Party councillor riding a tricycle during a local election campaign, and told him that a small windmill mounted on his head might generate enough electricity to propel this contraption along. He wasn't the least bit amused.....but then, when was the last time that you saw a Green Party member laugh?
