Abstract
A heating system comprises a source of rotational motion, at least one pump, a primary heat storage system, and one or more loops of piping connected to the primary heat storage system. The source of rotational motion, which may be a wind turbine, is configured to drive the at least one pump. The at least one pump is configured to pump liquid to repeatedly circulate around the one or more loops of piping, resulting in frictional heating of the pumped liquid and transfer of heat to the primary heat storage system. The system may comprise a secondary heat storage system, the pump may have an efficiency of less than 20%, the wind turbine may have drag-style blades, and/or the system may comprise a flow valve to regulate a flow rate of the pumped liquid.
Claims25
A heating system, comprising a source of rotational motion, at least one pump, primary and secondary heat storage systems, one or more loops of piping connected to the primary and secondary heat storage systems, and a heat pump connected between the primary and secondary heat storage systems, wherein the source of rotational motion is configured to drive the at least one pump, wherein the at least one pump is configured to pump liquid to repeatedly circulate around the one or more loops of piping, resulting in frictional heating of the pumped liquid and transfer of heat to the primary and secondary heat storage systems, wherein the primary heat storage system is configured to store a smaller amount of thermal energy at a higher temperature than the secondary heat storage system is configured to store, and wherein the heat pump is configured to transfer thermal energy from the secondary heat storage system to the primary heat storage system.
