I posted last week about why burning wood was carbon neutral. I found this on a camp site in Langdale. The National Trust have installed what must be a wood burning energy plant. Actually, reading the third picture, it's probably a fancy way of saying that they use wood to boil water. When they say 150kW, I wonder how many hours it runs for. But I particularly like the diagram of the Carbon Cycle. Not really sure about the left arrows at the bottom. They show energy when they should really show a molecule with carbon in. But it's good to see a scientific explanation.
