Abstract
A marine propulsion and power supply for maritime vessels that includes an arrangement of modules that can be internal combustion engines, regenerative electric motors, engine generators, turbine generators and/or battery banks. These components can be arranged in such a way as to work together to increase efficiency and to utilize various fuel combinations to achieve the lowest overall operating cost or other goals whilst minimizing harmful emissions. Sensors can be used monitor various power parameters and can be coupled to a closed-loop in a control system to achieve vessel operating goals.
