The invention provides in one embodiment a heat exchanger module (1) comprising a) a flexible support (100); b) at least one tubular member (200) having its main axis substantially parallel with the plane of the flexible support (100); c) a conductive flexible matrix (300) embedding the at least one tubular member (200); and d) a flexible case (400) enwrapping the flexible support (100), the at least one tubular member (200) and the conductive flexible matrix (300). A coating for a built environment comprising a plurality of heat exchanger modules (1) can be implemented, as well as a system further including pumping means (600). The invention also foresees a method for providing heat exchange processes between the heat exchanger module (1), the coating or the system of the invention and a built environment.

The present invention relates to a material and process for producing water- and oxygen-free halogen salts of an alkali metal or alkaline earth metal, or of a transition metal, or of a metal of groups 13 or 14 of the Periodic Table, in which at least one halogen salt is heated with a heating rate of from 0.2 K/min to 30 K/min, especially from 1.0 K/min to 10 K/min, proceeding from room temperature.

The invention relates to an auxiliary engine system (AES) for heating an electric car comprising a heating system and a rechargeable power source powering an electric motor. The AES comprises an internal combustion engine (ICE) producing heat to heat the electric car. The AES can heat people transported in the electric car and/or the rechargeable power source. The ICE can be coupled with an electric energy generator. The ICE can be air and/or liquid cooled which systems can heat the electric car. The ICE can be fueled by defined types of fuel. The ICE can be a two-stroke engine, a four-stroke engine, a turbine. The rechargeable power source can be coupled with a defined electrocomponent. The AES can be provided in a modular system. A heating method for an electric car is proposed.
