  • Patent number: 5970712
    Abstract: A combined material conveyor and electrical generation system is disclosed. The invention may be used to provide electrical energy to a remote location through which the material conveyor passes and/or harness energy which would normally be dissipated in braking a material conveyor. One or more electrical generators is driven by the motion of a belt in a material conveyor. Electrical power generated by the generator is delivered to an external power output. The invention can capture the potential energy of particulate matter which is transported on a material conveyor, particularly through a net elevation drop. Electricity produced may be used immediately or stored in a battery system for future use.
