Miscellaneous pictures.........
Why does the sun never come out for the group photo?
This is the bigger of the two machines we finished during the course.
Rotor diameter is 8 feet (2.4 metres).
Guemes Island Resort, where we stayed. Chris Freitas of Ouback
stops by with his wireless winch.
Robert Preus came to talk to us. Robert
is the distributor for African Windpower
in
the USA. There was one AWP machine in the classroom, and another
on a 150 foot tall tower across the road. The one on the tower looks pretty
small.
Later, Robert gave us a talk about how wind turbines fail. In
the picture below he has a hub from a Jacobs machine.
Andy Gladish was in charge of metalworking but he can also do stick
welding.
Here are Dan Fink and Dan Bartmann. They supplied the magnets,
the wire and some music.
They also worked hard on the smaller of the two machines. Here
Dan Bartmann applies some subtle persuasion.
An evening session on 'magnets at work and play'
Course staff from top left : Ian Woofenden (SEI and Home Power), Brain
Faley (Shoreline Power), Andy Gladish and BJ Daniels of Guemes
Hugh Piggott, and Win Anderson and Michael McGuinnes of Guemes
We were using Win's shop for the week. BJ and Win helped with
tbe woodworking.
Dan Whitney came back and brought the machine he built last
time using a Ford truck brakedrum.
Putting the larger machine onto the tower for erection. The tail
is a map of the island.
The big machine is on the tall tower (twenty feet up but still not
nearly tall enough)
and the little 4' diameter machine is on a short stand in the foreground.
Of course we had no wind to speak of and the best I saw was a 7 watt
ouput.
Later we did truck testing of the small machine. I recorded 30
amps output at 16 volts.
But to get that output I had to hold down the furling tail and we had
to hit about 45 mph.
Not very scientific, but lots of fun!
At 30 mph we got about 10 amps at 15 volts and the tail was starting
to furl.
