The invention relates to a toroidal electric generator (100) comprising a stator (20), which includes a tubular body (21) supporting a plurality of windings (24), and a rotor (30) rotatable within the stator (20) and comprising a support element (31) and a plurality of hydraulic blades (32), each provided with a respective magnet (34) and mounted on the support element (31) integral to it. The toroidal electric generator (100) further comprises an external casing (40) and a plurality of separating elements (51, 52), each separating element being arranged between a respective pair of adjacent windings (24) of the plurality of windings (24) of the stator (20).

An apparatus and a method of for energy conversion to dual-functionality are disclosed. The apparatus includes a storage container configured to store a working medium fluid and a pressure release valve configured to release the working medium fluid. A vane motor receives the working medium fluid at a high pressure. An embedded heat exchanger is encased within the vane motor that creates an interface between the working medium fluid within the vane motor and an energy carrier fluid, for heat exchange to occur therebetween. Upon the heat exchange, the temperature and pressure of the working medium fluid increases and the temperature of the energy carrier fluid decreases. The vane motor within an electric generator act as rotor, is rotated under combined effect of the working medium fluid entering the vane motor at high pressure and the pressure of the working medium fluid increasing upon heat exchange.
