A new method of utilizing the power
of running streams has been devised by
VI. Tan, Russian engineer. His APP
paratus consists of an endless cable car
rying a series of canvas cones which open

ley suspended from buoy. On the lower
part of the rope the cones are opened and
forced forward by the current of water,
thus setting in motion shaft or drum.
