A device for capturing energy from a fluid flow having a lift generating element with a lunate surface adapted to drive the device in oscillatory motion

摘要

A device for capturing energy from a fluid flow is disclosed. The device comprises a base, a longitudinal member, a lift generating element, and an energy transfer mechanism. The base is stationary and is mounted relative to the fluid flow. The member has a longitudinal axis, and is movably connected to the base. The lift generating element, connected to the member, has a leading edge and a trailing edge and a generally lunate surface extending therebetween. The lift generating element is movable relative to the direction of the fluid flow to vary a direction of lift produced by the lift generating element as fluid flows around it. The generating element drives the member in an oscillatory motion relative to the base. An energy transfer mechanism is attached to the member and is driven by the oscillation of the member.
