Patent number: 7061129Abstract: The generator comprises at least one source of pressurized gas and a closed hydraulic circuit containing a solution comprising an electrically conducting vehicle liquid in which a charge of micro- or nanoparticles of a metal material is dispersed. The circuit has at least one inlet port connected to the source so that, when in operation, it receives a flow of pressurized gas capable of causing circulation of the solution within the circuit in a predetermined direction, forming a two-phase gas-liquid mixture with it, a restriction in cross section, downstream from the inlet port calibrated in such a way as to cause an increase in velocity and condensation of the two-phase mixture, and at least one outlet port, located downstream from the restriction through which the gas mixed with the solution can be released and discharged from the circuit.Type: GrantFiled: December 20, 2004Date of Patent: June 13, 2006Assignee: C.R.F.

Publication number: 20050155339Abstract: A rotary combustor, and electricity generator including a stationary structure and at least one tubular annular rotor able to rotate about a shaft by means of contactless suspension devices, and in which is defined an annular combustion chamber having a directed lateral efflux opening for the ejection of gases produced in the combustion. The rotor has a narrow circular slit through which there extend, at predetermined angular intervals, into the combustion chamber, stationary injectors of fuel and oxidizer, and associated igniters, also stationary. A control unit controls the injectors and the associated igniters in a sequential cyclical manner, with predetermined time lags, in such a way as to generate and then sustain a detonation wave which propagates essentially continuously through the chamber, and bring about a rotation at controlled velocity of the rotor due to the action of the gases emitted through the lateral effusion opening.Type: ApplicationFiled: December 23, 2004Publication date: July 21, 2005Inventors: Pietro Perlo, Gianfranco Innocenti, Anatolii Zvezdin, Piermario Repetto, Marzia Paderi
