Patent number: 11738842Abstract: A marine vessel can be propelled by using wind or solar energy. This propulsion results in the forward movement and six degrees of motion (roll, heave, pitch, yaw, surge, and sway) of the marine vessel. This invention capitalizes on the fact that solar, wind and wave energy are cyclical by nature. The invention enables the vessel to manage stored and harvested energy and use the stored energy during periods when the external natural sources of energy are not available in adequate quantities to maintain a reasonable speed of advance for the vessel. The vessel's natural energy management system (NEMS) manages it in such a way that harvesting of the energy during high energy cycles, storing it and using it when needed during low external energy cycles, allows a marine vessel to maintain faster average speed without reliance on any fossil or chemical fuel and by only using renewable energy sources.Type: GrantFiled: September 10, 2021Date of Patent: August 29, 2023Inventor: Anil Raj
