The present application includes a system for generating energy via a rotating drum. The system includes a housing, a drum, and a plurality of enclosed chambers. The housing surrounds the drum and helps to distinguish between a gravitational domain and a buoyancy domain. The drum is coupled to a shaft and configured to rotate within the housing about a central axis. The plurality of enclosed chambers are radially aligned around an internal surface of the drum. The drum is exposed to a gravitational domain and a buoyancy domain simultaneously so as to induce rotation of the drum around the shaft. The enclosed chambers are subjected to gravitational forces in the gravitational domain and the enclosed chambers are subjected to buoyancy forces in the buoyancy domain.

The energy conversion device 1 consists of a liquid tank 11 in which liquid 10 is stored, a plurality of gas receiving sections 12 that are installed vertically in the liquid tank 11 and can rotate or move vertically. The energy conversion device 1 consists of a liquid tank 11 in which liquid 10 is stored, multiple gas receiving sections 12 installed vertically in the liquid tank 11 that can be rotated or moved vertically, nozzles 13 that blow compressed gas from below the gas receiving section 12 located at the bottom in the liquid tank 11, and nozzles 14 that store compressed gas as a primary energy source and blow compressed gas from below the gas receiving section 12. In the liquid tank 11, there is a nozzle 13 that ejects compressed gas from below the gas receiving section 12 located at the bottom, a gas cylinder 14 that stores compressed gas as a primary energy source and delivers compressed gas to the nozzle 13, and a gas receiving section 12 that receives compressed gas from the nozzle 13. The gas receiving section 12 receives compressed gas ejected from the nozzle 13, and the buoyancy force generated in the gas receiving section 1 2 by the buoyancy force generated when the gas receiving section 12 receives compressed gas from the nozzle 13, and the output means 3 that outputs the kinetic energy of rotation or upward movement to the outside of the liquid tank 11 as secondary energy. 1 1, and a recovery device 4 that returns the gas from the liquid tank 1 1 to the gas cylinder 14.

An example system comprises an enclosure configured to be submerged in a body of water. The system also comprises a capture device coupled to the enclosure. The capture device includes a rotor shaft and a plurality of blades coupled to the rotor shaft. The plurality of blades are arranged to receive a flow of water when the enclosure is submerged in the body of water. The flow of water causes the plurality of blades to rotate the rotor shaft. The system also comprises a transfer device extending lengthwise from a first end to a second end of the transfer device. The transfer device is mechanically coupled to the capture device at the first end and configured to transfer a torque of the rotating rotor shaft from the first end to the second end. The second end is located outside the enclosure.

A vacuum pump generally comprises a low pressure portion and a high pressure portion separated by a gas impermeable partition. Gas molecules exit the low pressure portion through an opening in the partition and passively impinge on a featureless rotatable surface in the high pressure portion. A drive rotates the rotatable surface with tangential velocity in the supersonic range at multiple times the most probable velocity of the impinging gas molecules. Impinging gas molecules are ejected outwardly from the periphery of the rotatable surface generating a substantial net outward flow of gas and reducing the pressure in the low pressure portion. The vacuum pump is effective to reduce the pressure in the low pressure portion to a target minimum pressure without using seals to prevent gas molecules from leaking back to the low pressure portion and without using blades or vanes to actively impact the gas molecules.

A method and system are provided for cooling a heat-exchanger in a wind turbine that has an electric generator with a cooling air flow directed therethrough. Effluent cooling air flow from the electric generator is directed into an air ejector pump and acts as motive air through the air ejector pump. Cold air is drawn into the air ejector pump by the vacuum generated by the motive air moving through the air ejector pump. The heat exchanger is disposed in-line with the cold air flow so that the cold air is drawn through the heat-exchanger, removes heat from the fluid circulated through the heat-exchanger, and becomes heated air that is combined with the motive air and discharged from the nacelle.

For a refrigerant compressor, a flexible connection element that connects an end segment of a suction connection piece, which end segment protrudes into the interior of a housing, to a suction sound damper, in particular to a suction opening of the suction sound damper. The end segment itself thereby serves for fastening the flexible connection element onto the end segment and/or the inner wall of the housing.

The process involves the creation of an artificial wind within a covered and enclosed powerplant facility in order to initiate the mechanism to rotate several wind motor generators to induce and generate consistent electricity output. A covered plant facility houses multiple wind generators arranged in a random sequence to gain more wind sweep from each turbine of the wind generators. Several powerful blower fans act as prime movers to push atmospheric air inside the wind plant facility. Artificial wind within the facility is thus pushed, controlled, generated and mimics the outside atmospheric condition. A compact wind power generator covered facility shall house several motor wind aerodynamically designed turbines to induce controlled artificial wind condition pushed by powerful blower fans and transfer of energies from mechanical to electric energy to produce consistent and efficient electricity output from several generators lacking in conventional outdoor open air wind farm.
