RES - Hull integrated propulsion The RES Institute proudly presents the patented hull integrated propulsion for ships featuring a multitude of pod units which use swarm intelligence to maneuver the boat. No more tugboats are needed when entering the port. The ship is capable to maneuver on its own. The catamaran like underwater uplift bodies are tanks for storing H2 as a fuel for fuelcells, which drive the electric pods. There is more to come, why don't you ask the inventor?
