<b>Wind powered pumps</b>

In several countries, low-cost windmills are used to power piston pumps. Examples include the Miramar mills in Peru, the Poldaw mills in Africa and Baptist mills in Bolivia.

<b>Rural electricity</b>

As an option, wind rope pumps can be combined with a permanent magnet generator to charge batteries for a few light bulbs and a television. There are also small wind generators based on the design of the wind rope pump.
