Folding tower. Makes it easy to maintain or modify the windmill. Only takes a couple of minutes to raise or lower.

Big windmill during a very windy night. There are 3 100watt spotlamps pointed up, connected across the output.

New propeller hub design. After feedback from others I redesigned the hub. Its now half the weight and easier to assemble, plus cheaper.

A new set of blades. These were carved by Dennis Latham of SA, and are a big improvement over my own blades.

Close up shows the de-cogged stator and hub clearance, approx 0.5mm

I photographed this monster in central Queensland. Blade diameter is 8.2 meters ( over 27 feet ) ! Originally from the Bungaban station, the mill was donated to the Wandoan & District Progress Assc for restoration and its now in the W.O'Sullivan Memorial Park

First ever VAWT windmill. These are strange little things. Lots of torque and will start in a light breeze. Worth looking further into.

The offset bearing for the VAWT. I got the idea for this windmill from www.windstuffnow.com

VAWT fitted with a toothed belt drive and stepper motor, results OK, on going project.

My first stirling engine. Runs on a cup of hot coffee

Another working stirling. These are fun to make and you learn a lot about tolerances and friction trying to get them running.

A quick stator change, with tower tilted down. The windmill design means I can change a stator in less than 5 minutes, including lowering and raising the tower. Note the adjustable balancing plates on the blade brace.
