This first SEI workshop on 'how to build a wind turbine' was a success. Here are some pictures of the processes and personalities. It's a long page with over 60 pictures, so take your time :-)
THERE WILL BE ANOTHER COURSE AT THE SAME LOCATION ON
14-19 APRIL 2003
CONTACT Ian Woofenden FOR DETAILS
I am grateful to Solar Energy International, and especially to Ian Woofenden for making this happen. (Many of the pictures below are Ian's). Ian lives on Guemes island in a renewable powered home in the woods. He uses AWP36 and Whisper 1000 wind generators on 100+ foot tree-top towers as well as PV. Ian is also Senior Editor, in charge of text content at Home Power Magazine. I am also lucky to have him as a good friend.
Future workshop courses will
take place in Scotland (February and
May 2003), Wales (October 2002 and 2003
at CAT) and again in the USA (14-19 April 2003).
Most of us stayed at Guemes Island Resort - Hugh Glass brought his own
windpower from Utah.
Here is Win Anderson the shop owner giving up his valuable time to guide
the students in wood carving techniques. We are most grateful to
Win for the use of his spacious and well equipped wood shop, and the adjoining
covered area for metal working.
Brian Faley was our plastic and
electrical shop supervisor. He is a senior engineer at Trace Engineering
(now part of Xantrex), and more than overqualified for the task.
I for one learned a load of useful stuff working with Brian and we all
appreciate his helping out.
We were very fortunate to have Tod
Hanley from Bergey
Windpower on the workshop. He explained some tricky concepts
such as 'low Reynold's Number airfoil design'. His BWC XL1 turbine
is a big leap forward in small wind turbine design. Thanks for coming,
Ron Richardson (right) of Kettle
Falls WA was a great asset in the metal shop.
Two other students brought parts for brakedrum machines:-
Gaetan Ayotte (Ontario) and Dan Whitney (Apple farmer from WA -- thanks for the apples Dan!)

The wiring and rectifiers go under a small aluminium weather-shield.

Below is the class erecting the machine by hand. This is not a
very safe or satisfactory way to raise a wind machine, but it happened
very fast, and for a very short tower it can be a fun way to do it.
Here you can see the complete machine in action. You can almost
see through the air gap between the magnet rotors. We observed outputs
around 100-200 watts in windspeeds around 10-15mph.
Dan Whitney later put his brakedrum machine up on a hilltop to power
a radio mas. The bus headlights are the dump load.
