Abstract
An energy efficient ship is achieved by powering the ship using at least one propulsion level, each propulsion level having large grids at the forward and stern ends of the ship and side channels incorporating turbines that move water through the ship, rather than around the ship, thereby substantially eliminating energy wasting wakes and cavitation.
Claims20
A ship comprising a main body portion carried by at least one propulsion level, said propulsion level comprising a port forward chamber, a port stern chamber, a port channel extending between the port forward chamber and the port stern chamber, a starboard forward chamber, a starboard stern chamber, a starboard channel extending between the starboard forward chamber and the starboard stern chamber, a forward grid structure and a stern grid structure, at least one port turbine positioned between the forward grid structure and the stern grid structure and adapted to cause fluid to flow along a first path through the forward grid structure, the port forward chamber, the port channel, the port stern chamber and the stern grid structure, and at least one starboard turbine positioned between the forward grid structure and the stern grid structure and adapted to cause fluid to flow along a second path through the forward grid structure, the starboard forward chamber, the starboard channel, the starboard stern chamber and the stern grid structure.
A ship comprising a main body portion carried by a plurality of separately operable propulsion levels, each of said plurality of propulsion levels comprising a port forward chamber, a port stern chamber, a port channel extending between the port forward chamber and the port stern chamber, a starboard forward chamber, a starboard stern chamber, a starboard channel extending between the starboard forward chamber and the starboard stern chamber, a forward grid structure and a stern grid structure, at least one port turbine positioned between the forward grid structure and the stern grid structure and adapted to cause fluid to flow along a first path comprising the forward grid structure, the port forward chamber, the port channel, the port stern chamber and the stern grid structure, and at least one starboard turbine positioned between the forward grid structure and the stern grid structure and adapted to cause fluid to flow along a second path comprising the forward grid structure, the starboard forward chamber, the starboard channel, the starboard stern chamber and the stern grid structure.
A ship comprising a main body portion carried by a propulsion level, said propulsion level comprising inner and outer port walls, each having a forward end and a stern end, surrounding a port channel, inner and outer starboard walls, each having a forward end and a stern end, surround a starboard channel, at least one port turbine in fluid communication with the port channel, at least one starboard turbine in fluid communication with the starboard channel, said inner port wall and said inner starboard wall joined together at their forward ends by a first funnel and at their stern ends by a second funnel, said outer port wall and said outer starboard wall joined together at their forward ends by a forward grid and at their stern ends by a stern grid, wherein first and second forward chambers are defined by the forward grid, the outer port wall, the outer starboard wall and the first funnel, first and second stern chambers are defined by the stern grid, the outer port wall, the outer starboard wall and the second funnel, and wherein the port channel extends between the first forward chamber and the first stern chamber, and said starboard channel extends between said second forward chamber and said second stern chamber.
