In January, the New Scientist wrote about Windsave Ltd, a Scottish company manufacturing wind turbines for domestic use, including an embedded generator unit that quite simple plugs into a standard (UK) 13 amp wall socket. With a bit of a breeze, the unit starts feeding energy into the grid. While your electricity meter may not run backwards (most are designed not to), this could still make an impact on the electricity bill. It would certainly make a huge impact on my conscience, on the grounds of it may not be much but I’m doing what I can.
It’s too bad I haven’t got the right walls. I need to think about other ways of mounting, but I doubt my chimney is strong enough. Just while I write those lines not a single leaf moves outside, anyway.
