The paper presents an invention regarding a SPM smart power module, intended for the creation of distributed, safe and efficient energy networks. An elementary module is composed of an innovative Carnot Battery, with high power density, consisting of a heat engine / heat pump whose working agent (gas or vapor) goes through a Carnot / Ericsson / Stirling cycle and which transfers thermal energy between two accumulators with different temperatures. In supply mode, the cycle is run in the direct direction and supplies mechanical / electrical energy, and in charging mode, the heat pump receives energy from the outside (from the network or from renewable sources), and the cycle is run in the opposite direction, transferring thermal energy from the cold reservoir to the hot reservoir. The maximum efficiency of the battery is ensured by at least two isothermalizers, similar to the one described in PCT / R02023 / 050009. Through a system of tanks, heat exchangers, circulation pumps, solenoid valves and pipes, the elementary module can receive a series of extensions, both on the thermal energy capture and distribution side. An intelligent processor collects signals from the SPM system, from a dispatcher, from the Internet, etc, processes them, then sends commands to the motors that actuate the solid pistons of the isothermalizers, the flow regulators of the liquid pistons and of the cooling systems, the solenoid valves, the circulation pumps, in such a way as to ensure the maximum exergetic and economic efficiency of the module, the flattening of load peaks, the maximum safety, the maximum utilization coefficient of all components. Any energy production unit and any consumer can be included in a smart module that ensures the storage, then the supply of the entire energy offers, ensuring consumers a safe, uninterrupted supply.

The present invention discloses an expansion engine that, by means of a cycle similar to the Carnot cycle, converts thermal energy in general, and solar energy in particular, so as to transform the heat from a hot source and a cold source into mechanical work and subsequently into electrical energy. There is no economically viable means in the prior art for converting heat resulting from small temperature differences into work. This applies both to systems based on the Rankine cycle and to those based on the Stirling cycle. The present invention generates useful energy from an inexhaustible source such as the sun, using an abundant resource such as water, in a closed circuit. When applied to the utilization of solar energy, the expansion engine has the notable advantage of using virtually the entire spectrum of solar radiation, from infrared and visible light to ultraviolet, and not just a fraction of the visible spectrum, as is the case with photovoltaic panels. The invention is aimed at the production of energy from vast heat sources resulting from small temperature differences, such as those available in geothermal sources, from the temperature difference between surface water and deep-sea water, or from water heated by solar thermal radiation. The present invention enables the production of energy at the required locations and in the required amounts, thereby eliminating the need for electrical distribution networks. The present invention encompasses a system for storing large amounts of energy.
