Title: Innovations by Daniel G MacDonald
Introduction
Daniel G MacDonald is an accomplished inventor based in Mashpee, MA (US). He has made significant contributions to the field of wave energy conversion, holding a total of five patents. His work focuses on developing innovative technologies that harness the power of ocean waves for energy generation.
Latest Patents
Among his latest patents is the "Pivoting AUV/UUV dock for use with a wave energy converter." This invention features an AUV/UUV docking station that is tethered to a wave energy converter, which is in turn connected to a flotation buoy. The docking station is designed with a cone to guide the AUV/UUV into a charging dock that can rotate between horizontal and vertical positions. This design minimizes interference with the wave energy converter's operation while allowing for efficient charging of the AUV/UUV.
Another notable patent is the "Oscillating tension wave energy converter." This unique device employs a point absorber type wave energy conversion mechanism. It includes a Power Take Off (PTO) that utilizes a torsion spring to return a vertical shaft to its original position after being rotated by a rope or cord. This innovative spring return mechanism allows the PTO and housing to remain stationary under wave energy, while a buoy at the surface generates oscillating linear movement. The resulting oscillating rotary motion is converted into unidirectional motion and transmitted to generators through a gearbox that increases rotational speed.
