Patent ID: 8303213

Claim:
A circuit for flowing water through a wave generating channel, comprising: a water reservoir, water pump, a nozzle, wave generating channel, water drain, and water return channel, the water reservoir further comprising a first water smoothener; the water pump adapted to urge the water to flow from the water reservoir, through the first water smoothener, through the nozzle, through the wave generating channel, through the water drain, through the water return channel, and back to the water reservoir; the wave generating channel adapted to generate waves as the water flows through the wave generating channel; and the first water smoothener comprising a first array of apertures at least two of which have parallel longitudinal axes at a first angle, the first water smoothener further comprising at least two faces wherein the apertures provide passage from one face to the other, the first water smoothener adapted to reduce turbulence in the water when the water flows through the first array of apertures.
