Wind Power - Mechanical and electrical power generation from Wind. 

The sun heats the air and the earth's surface unevenly - which causes wind.

Wind has been used as an energy source for thousands of years. Up to 4000 years ago, the Babylonians and the Chinese used wind power to pump water for crops, and sailing boats were around long before that. Wind power was used in Europe in the middle ages to mill (meaning grind) grain. This is where the term windmill comes from.

In modern times, wind generators, are used to generate electricity. The blades or sails or the turbine drive the generator. To increase the amount of electricity produced, a number of turbines can be placed together in the same area, forming a wind farm.

The best places for wind farms are coastal areas, gaps in mountains, the tops of rounded hills and open plains. To be economical, the average wind speed at a wind farm should be about 25km/h.

A Wind Mill is technically a machine powered by the wind for the purpose of grinding grain into flour. The old Dutch windmills were generally used for this purpose. A Wind Pump, on the other hand, is a machine that uses the wind's energy for pumping water. Those machines that convert wind pressure into electricity are Wind Generators.

Wincharger Restoration Project

I picked up the Wincharger 1222H last Saturday, spent most of the week building a workbench and some storage area in the new rent house and generally getting things ready to go. This evening, Friday, 12 April 2002, marks the day the project actually started. This is the first installment in what will become a 'restoration journal.' My intention is to provide enough facts, tips and details here for this site to serve a a manual or textbook for others who are restoring Winchargers. We'll have images to go with the words. First part of the project was to pose all the components on the bench for a 'before' photo.

So You Want To Build A Wind Generator?

Diffuser Augmented Wind Turbine (DAWT) - Ducted, Shrouded, Diffusers, What ever you want to call them. The venturi effect even.
Mankind has made big efforts to concentrate the wind for increasing the natural wind velocity or to enlarge the power ratio. Wind tunnel investigations have delivered some hopeful result, but this was never proofed in reality, until today.
