Good concept.
We here in France, at
http://www.echorenovate.com/ (not for profit) have a more rounded approach to sustainability.
My 3 boys are growing up fast, and the stuff I am writing and doing is for them. My eldest, 15 years old, is now asking all those awkward questions, like, "But daddy when the magnet passes over the coil, what is actually inducing an electrical field, yea yea magnetisism, but what?" Keeps me on my toes. He's playing Rugby this afternoon for a French team. !
At first Children, my boys mates, take some time to get interested, but once they have done some hands on stuff, it stays with them for ever. Some folk that have been here have gone away and started totally different life careers.
However, my Mrs reckons I am a lousy teacher, as I sometimes get lost in the minutiae. So I have to stick to her notes, and as she says, "discuss the odd stuff over a pint/glass or 2 of the local wines, in the evenings please!".
Good luck and have fun.
