The Center Contains A Vortex

Changing A Wave's Kinetic Energy To Mechanical Energy By Means Of A Vortex:



is a natural swirling motion in any fluid such as water or air. In water, it is often called a whirlpool. In air, it is called a tornado. A true vortex is very efficient as an energy storage device. Viscous losses are minimal, its spin persists for some time. A vortex is, in a real sense, a fluid flywheel.

Dam-Atoll, Vortex, Guide Vanes:

The design of Dam-Atoll features a vertical cylindrical chamber at its center that facilitates the formation of this fluid flywheel. We've seen how the optimal shape of the atoll delivers approaching waves in a spiral path towards the center of the atoll, where the waves progressively break. A set of guide vanes at the top of Dam-Atoll's submerged dome directs each breaking wave into the vertical central vessel tangentially, resulting in a powerful whirlpool. Any wheel or array of paddles, any propeller or paddle-wheel in this whirlpool will be forced to spin at the same rate as the whirlpool. By attaching the paddles to a shaft, you will enable the shaft to deliver mechanical power, for example to an electrical generator. This, in sum, is how Dam-Atoll works.

Smoothing Out The Succession Of Wave Pulses:

Each successive turning vane delivers its flow contribution in succession. This serves to smooth out the individual pulses of wave energy, much as a radial aircraft engine smooths out individual cylinder pulses. By the time the last portion of a wave enters the rear guide vanes, a new wave is just entering the first set of guide vanes. This smooth action is most clearly seen in the slow motion portion of the video focussed on the waves entering the turning vanes. (next)
