Patent ID: 8425779

Claim:
A method for converting fluctuating and/or erratic energy into a stable energy supply, wherein the fluctuating energy is produced by at least one of solar energy, wind power, waves and water currents, the method comprising: delivering the energy to a first pump integrated in a pressure circuit for delivering stable energy, the pressure circuit comprising a first pressure amplifier with a double-cone device (DCD) driven by a first fluid flow circulated by the first pump, inserting a second fluid into the pressure circuit with the DCD to elevate the pressure in the pressure circuit, collecting the first fluid in a storage site having a high-pressure outlet for delivering a continuous high-pressure fluid flow through the high-pressure outlet, feeding an outlet stream of the first fluid of the first pump into a second pressure amplifier, the second pressure amplifier sucking in a gas through its inlet, feeding the outgoing pressurized first fluid with gas into a liquid-air separator for separating the gas from the first fluid, and collecting the compressed gas in a compressed air vessel connected to the separator to produce in parallel to high-pressure fluid a continuous high-pressure air supply.
