Dear Paul
I enclose an image of the Lego model which was used by myself (and my 9 year
old daughter) to develop the concept for maintaining the horizontality of
the wheel. It also had a "sophisticated" lego brick attachment which looked
at the idea of a water driven wheel using ballast tanks in the form of hooks
at the end of each arm.
best regards
Tony Kettle
