A heat storage and transfer system incorporates a primary heat storage chamber that is thermally insulated and which in use, contains a heat storing liquid or solid and a thermal energy to electrical energy converter in or thermally coupled to at least one of: i) a secondary chamber external to and adjacent the primary heat storage chamber through which a liquid or steam to be heated is passed in use; and ii) a thermal conduction plate/surface external to the thermally insulated primary heat storage chamber or body. The system has a heat transfer feature to selectively transfer thermal energy from the heat storing liquid or solid of the primary heating chamber to the thermal conduction plate or the liquid or steam to be heated in the secondary chamber for the thermal energy to thence be converted to electrical energy by the thermal energy to electrical energy converter.

Thermal energy storage systems are disclosed in this application. Systems of the inventive subject matter are designed to reduce maintenance requirements by sequestering, for example, corrosive fluids that might otherwise damage difficult-to-fix internal components are kept out of those components by introducing a non-corrosive heat transfer fluid to facilitate heat transfer between a thermal energy storage medium (e.g., molten sulfur) and a potentially corrosive working fluid. Thus, the potentially corrosive fluid is kept out of a thermal energy storage tank containing the thermal energy storage medium, which, by design, is difficult to repair when internal components corrode or otherwise require maintenance.

A heat emitting radiator for use in a fluid circuit containing coolant therein, and which can generate substantial amounts of heat to heat larger spaces, such as in a home or business, while utilizing minimal power to run, and which can be utilized in various implementations and configurations. The radiator can be selectively activated or de-activated by, for example, a cell phone or the like whereby the fluid circuit in the radiator can be monitored for time of use, temperature and cost of use.

A power plant for generating electrical energy comprises at least a heat storage device (100) for storing electrical energy in heat energy, comprising: an electrical heater (10) for converting electrical energy in heat energy; a heat storage body (30, 31) for receiving and storing heat energy of the electrical heater (10); a heat exchanger (50) for receiving heat energy from the heat storage body (30, 31). The power plant further comprises a turbine (120) and a generator (123). A heat storage fluid circuit (130) connects to the heat exchanger (50) or the heat exchangers (50) and a working fluid circuit (140) connects to the turbine (120). A fluid circuit heat exchanger (131) transfers heat from the heat storage fluid to a working fluid in the working fluid circuit (140).

The present invention relates to an electric water heater having an instantaneous hot water storage-type structure allowing a continuous outflow of a large amount of hot water instantaneously, without having to heat the water accommodated inside a housing directly. In the present invention, since the water flowed into the housing is heated while passing through the first and second heat exchange pipes, there is an effect that a large amount of hot water is instantaneously provided without having to heat a large amount of the water accommodated in the housing directly.
