Plan and
elevation. A tank nearly filled with water and two wheels marked a, a and b, b are placed in the water in the
tank. By capillary attraction the water rises between the two wheels
marked x, x, to a height above the level of
the water in proportion to the distance of the wheels from each other
at x, x. As the water rises between the
wheels marked x, x, above its level, the weight of
water between the wheels will cause the wheels to continually revolve.
