Abstract
A fluid energy machine for imparting energy to a fluid. A channel contains a fluid flow. A flexible membrane extends the length of the channel and has a width generally corresponding to the inside width of the channel. A drive actuator at the input end of the channel imparts an activating force to the membrane at the input end of the channel, causing a transverse wave to propagate along the membrane and drive fluid through the channel.
