Abstract: An automated energy generating and energy using system is provided. The system includes at least one electric energy user, at least one electric energy source, and may also include at least one electric energy storage element. These elements are instrumented so that each electric energy user has a sensor for determining an amount of energy used, each electric energy source has a sensor for determining an amount of energy provided, and electric energy storage element has a sensor for determining an amount of energy available in the storage element. A controller is operatively connected to each energy source, energy storage element and sensor. The controller is configured to control a level of operation of the at least one source of energy based upon at least the amount of energy used and the amount of energy available in the storage element, if employed. In this way, an automated electrical energy system is provided.

Abstract: The present invention is directed to a continuous, portable dredging system that employs a series of screens and gravity separation devices with flocculation to remove sediments from the dredged slurry. The system produces a treated water stream having low solids content and a recovered solids product having a low water content.

Abstract: An auxiliary propulsion system for a boat or other marine vessel according to the invention incorporates an electric motor/transmission device for generating locomotive force to propel the boat or vessel, an electrical power supply for providing electrical energy to drive the electric motor/transmission device, at least one electrical energy generating device for generating electrical energy through conversion from one of at least sunlight, wind motion and water motion, a charging circuit having a device for controlling charging of the power supply with electrical energy from the energy generating device, and a device for controlling speed and direction operation of the electric motor/transmission device. In operation, electrical energy is inputted into the electric motor/transmission device from the electrical power supply and locomotive force is thereby generated by the electric motor/transmission device when the primary propulsion system of the boat or other marine vessel is inactive.
