Abstract
To achieve a flywheel effect and lower the power necessary to drive it, a float pump is modified and put to use in such a way that one-half of the stroke of the pump is powered by the negative or positive buoyancy of the system of reciprocating components through which the pump is operated. As a result, the pump can be powered by even human leg power, such as by driving it through a pair of cranks pedalled in the manner of a bicycle. A reciprocable drive mechanism for the pump is also disclosed and claimed.
