{"product_id":"9780956675132","title":"How to Build a Wind Pump; Second Edition","description":"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. 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 about 1000 litres a day with a head of 4-5 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.","brand":"Low-Impact Living Initiative","offers":[{"title":"Default Title","offer_id":49787288715504,"sku":"9780956675132","price":18.75,"currency_code":"USD","in_stock":false}],"url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780956675132","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
