Wind Power - Mechanical and electrical power generation from
The sun heats the air and the earth's surface unevenly - which causes
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. http://www.rebelwolf.com/wincharger.htm

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.

prepared by DanMar and Associates for the Southwest Regional
Commission (SWRDC), September, 1996. This report indicates that wind
development will provide economic diversification in Southwest
and concludes that local ownership of projects substantially increases
