Microgeneration

[Tin Pot]

Rain falls onto the roof down drain pipes and then into a 2500 litre underground tank from there it is pumped directly to the cistern/outside tap by way of a control box.

If you stuck a turbine in there, could you power the doorbell or something?

Reminded me of this bit of Randall Munroe's brilliant book "What If?"

I've often thought about little generator turbines in the water supply, or even built into the hinges of much used doors.

4m of annual rainfall offsets the cost of a generator in a century - cool.

Is there a decent way of doing solar, we've had a couple of the multinationals around, but all they are interested in is selling you their finance to purchase. They were costing out at £8K, around £11K after the interest & at least 25 years before you could re-coup the investment.

we used shadegreener.com no cost to us . ok they make the profit but we are doing our bit

I've made a fortune by harvesting all the hot air from @Markymark and selling to The National Grid.Thanks to him the good people of Leeds have heat in the winter (all 11 months of it)

But as most of Leeds is drunk on special brew I doubt they feel the cold much.
