In order to transfer the mechanical energy of water waves to the shore, the following model of a turbine has been created: The turbine has a rigid or a flexible axis that floats on the water surface in the direction of wave propagation. The axis is at least 1.5 times as long as the wavelength. One end of this axis is attached to a buoy and the other is on the shore. Both ends can rotate around themselves, but neither of them can move in the direction of wave propagation.

Flat fins (see figures), attached to the floating axis of the turbine, convert horizontal back and forth motion of waves into rotation of the turbine in one direction.

The turbine is different from other turbines in following details:

  1. The axis of the turbine floats on the water surface. Parallel forces acting upon it balance each other out, and the turbine doesn’t require any additional device for stabilization or use of wave energy.

  2. Energy naturally transports itself through the cable toward the shore. One end of the turbine needs to be anchored just to prevent it from drifting away.

  3. The length of the turbine and, therefore the potential amount of energy produced by it, is unlimited.

  4. Proper engineering can make the turbine stable, efficient and inexpensive to produce.

  5. In case of a strong storm, the turbine can be temporarily submerged.
