Delta 16 
Wind Driven Energy - Simplified Technology For the Future!
Having been responsible for the installation and monitoring the operation of twenty_one windmills in the West African County of the Gambia over the past ten years I can highly recommend the Delta 16.
The working parts of the windmill prove to be very durable and long lasting requiring a minimum of servicing. It operates effectively throughout a wide range of wind speeds, delivering water at surprisingly low windspeeds.
To assemble and install the windmill requires only a few simple hand tools and no special equipment.
