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.

An embodiment of the present invention relates to a cold and hot water supply and power generation system including a graphene-coated ceramic heating element, which can control temperatures of cold and hot water based on the graphene-coated ceramic heating element and a heat pump, use power generated by thermoelectric power generation based on a temperature difference between the cold and hot water, and supply the cold and hot water to a demand source or use the same for cooling and heating.

The present invention relates to a system (100) for generating heating and cooling power in a treatment plant (102) for workpieces, in particular a vehicle body paint shop (103), wherein the system (100) comprises the following: at least one cold water network (104) for supplying consumer processes (146) with cold water, which has at least one cold water storage device (110) for compensating process load peaks and/or at least one cold water network heat transfer device (112, 154, 158) for recovering heat from consumer processes (146); at least one warm water network (106) for supplying consumer processes (146) with warm water, which has at least one warm water storage device (120) for compensating process load peaks and/or at least one warm water network heat transfer device (122, 166) for recovering heat from consumer processes (146); and at least one heat pump device, in particular at least one first heat pump device (132),
wherein the cold water network (104) is connected to the at least one warm water network (106) by means of the heat pump device (132), and wherein the networks (104, 106) have different temperature levels.
