Paddle wheel
A paddle wheel is a waterwheel in which a number of scoops are set around the periphery of the wheel.
Usages
Pumping
A paddle wheel is only useful for very low lift pumping, such as flooding paddy fields at no more than about 0.5m height above the water source.[1]
Energy harvesting
A paddle wheel can also be used for energy harvesting.
Marine propulsion
Due to their ability to move water, paddle wheels are also used in marine propulsion.
