An apparatus for generating power includes a heated fluid reservoir including a heated fluid, a back-pressure control channel, an energy extractor coupled to the heated fluid reservoir and the back-pressure control channel, and a pressure ejector coupled to the back-pressure control channel. The back-pressure control channel includes a fluid mobilization device configured to circulate an internal fluid and to form a low-pressure region within the back-pressure control channel. The energy extractor includes an energy extraction rotor. The low-pressure region in the back-pressure control channel causes the heated fluid from the heated fluid reservoir to be entrained through the energy extractor forming an entrained fluid. The energy extraction rotor is configured to extract power from the entrained fluid. The pressure ejector is configured to transmit the entrained fluid to an exhaust reservoir.

A power generation system comprising a first vessel, a second vessel, a pump operably connected to the first vessel and the second vessel, and a turbine manifold assembly operably connected to the first vessel and the second vessel, wherein the pump creates a positive pressure in the first vessel to force a fluid in a first direction through the turbine manifold assembly and into the second vessel to a pre-determined level by a negative pressure in the second vessel, wherein, once the fluid reaches the pre-determined level in the second vessel, the pump creates a positive pressure in the second vessel to force the fluid in an opposing second direction through the turbine manifold assembly and back into the first vessel by a negative pressure in the first vessel to complete a cycle is provided. Furthermore, associated methods and a turbine manifold assembly is also provided.

A gravitational engine used to generate energy and its respective operation. The main elements to the performance of the equipment are the water, the force of gravity and the pendulum motion. The gravitational motor that generates energy 1 is set basically by a optionally rectangular reservoir 2, which holds a liquid, preferably water; a turbine 3, positioned internally in its higher point; and, a vertical tube 5 connected in the opposite end of the turbine.

An air compressor system includes: two or more compressed air tanks previously filled with compressed air; several compression chambers also filled with compressed air, each containing a small internal expandable tube; located inside a larger external heavy-walled tube bonded to endcaps containing one-way and two-way valves, rigidly attached to top and bottom outside tanks; a timed valve inside expandable tube allowing compressed air from top tank to expand that tube to inside of heavy-walled tube, compressing ambient air outside expandable tube that entered through one-way valves. A second timed valve opens, forcing the original air back into the tank bottom or for immediate use or storage. Several other compression chambers follow the same procedure nonstop, increasing the psi in tank for immediate use or storage. All FIG. 1A compression chambers share two common tanks, which fill from top tank 600 and empty in bottom tank 602 in sequence.
