The BBC website has a story about how the gunge from the production of Fosters lager (I don't think they're talking about the lager itself...) is being used to power a battery. At the same time there is the incredible new solar power station in Spain, if you saw the 10 o clock news last night, and the story is on the BBC site here (the most-read story on the site as I'm writing this).
Even the little picture here is quite awesome, never mind seeing the site itself. Makes me think again about solar roofing for our house, never mind all those south-facing slopes on church rooves up and down the country.
