How to Build a Windpump
[BWIN0580]
£11.95

Good for developed or developing countries, this wind pump can pump rainwater, greywater, river, pond or well water for irrigation, aerate a fish pond, run a water feature or even be a bird scarer. This system does not generate electricity. The turbine is 700mm diameter, and the turbine head plus rotor weighs less than 4kg. In a light-to-moderate wind, it should pump 1000 litres per day, with a head of 2-3 metres. If you have good engineering skills and equipment, you can fabricate nearly all of the system yourself; if you get all the parts manufactured, it's not much more complicated than DIY flatpack furniture. 115 pages.
