  • How to build a wind pump

    Author: Jim Barr | ISBN: 978-0-9566751-3-2

    Good for developed or developing countries, the wind pump described in this book 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. The turbine is 700mm diameter, and the head plus rotor weighs less than 4kg. In a light-to-moderate wind, it should pump 1000 litres per day, with a head of 3-5 metres. If you have engineering skills and kit, 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. 100 pages, £11.95. Buy from our partner, the Centre for Alternative Technology.

    There’s a crash coming – a slap from Mother Nature. This isn’t pessimistic; it’s realistic.

    The human impact on nature and on each other is accelerating and needs systemic change to reverse.

    We’re not advocating poverty, or a hair-shirt existence. We advocate changes that will mean better lives for almost everyone.
