Title: James George Purnell Dehlsen: Innovator in Marine Technology
Introduction
James George Purnell Dehlsen is a notable inventor based in Warkworth, New Zealand. He has made significant contributions to marine technology, holding a total of 4 patents. His innovative designs focus on harnessing marine energy and improving water production processes.
Latest Patents
One of his latest patents is the "Marine current turbine platform with faired spar." This invention features a downstream rotor, a faired spar, a deckhouse at the waterline, and a ballasting and mooring arrangement. This design ensures that the center of buoyancy is above the center of gravity, providing a stable platform and ample rotor torque reaction. The faired spar minimizes the wake deficit ingested by the rotor, reducing turbulence and drag on the turbine. The deckhouse adds buoyancy to counteract gravitational forces and provides reserve buoyancy if a portion of the platform becomes flooded. The mooring arrangement is designed to form a bridle, ensuring yaw stability.
Another significant patent is the "Reverse osmosis water production apparatus." This apparatus is designed for use in a body of water and includes a buoyancy chamber and an elongate chamber extending downward beneath the waterline. The elongate chamber contains multiple reverse osmosis membrane tubes, each aligned parallel to the chamber's longitudinal axis. This innovative design enhances the efficiency of water production through reverse osmosis.
