  • Publication number: 20180202414
    Abstract: A device and methods for capturing and converting ocean waves forward motion and other suitable wave forms which could have velocities similar to ocean waves and be suitable for efficient conversion into electrical power. The device comprises a receiving platform and wave capture ramp to direct active waves up the ramp and onto an elongated large cylindrical apparatus with perimeter receiving buckets to capture the waves water flow and thereby rotate the large elongated water wheel capture apparatus. Said apparatus absorbs both the kinetic energy as well as receiving and exploiting the potential energy component of the wave transfer to the multiple capture buckets to rotate the water wheel apparatus as a function of the volumetric filling and emptying of same as the apparatus rotates.

  • Patent number: 6821614
    Abstract: A method for forming a product from cellulosic material and thermoactive material is described. A mat is formed from a mixture having a predetermined amount of cellulosic material and a predetermined amount of thermoplastic material. The mat is then consolidated and pressed to a predetermined final product thickness. At least a portion of a surface of the mat or product is then surface modified. Consolidating the mixture may include forming a first face layer, forming a core layer on the first face layer, and forming a second face layer on the core layer. Forming the core layer may include depositing mixtures of wood flakes and plastic flakes according to mixture flake size in successive layers such that the core layer has larger flakes adjacent the first face layer and adjacent the second face layer, and smaller flakes in a middle portion of the core layer. The method also can include fusing a sheet of plastic material to at least one surface of the mat, and surface modifying the plastic material.

Consolidation can occur as a mat or composite moves through a hot-gas consolidation zone.
