The invention is a pump engine developed for the purpose of launching and pumping capsules in a hydraulic pipeline. The engine operates on the combustion and explosion of a mixture of fuel and oxygen bearing gases against a liquid piston that passes through a dynamic current turbine. The rotation of the turbine maintains a constant direction of rotation through the oscillation of the water column, and drives a special rotor to feed capsules from a hopper into the pipeline, while the liquid piston pushes them into the pipeline and applies the necessary pressure. The turbine also drives the necessary auxiliaries such as alternator and camshaft for water valves and air inlet and exhaust valves. The pump engine is built in single cylinder or multiple cylinders in duplex and fourplex configurations.

The present invention relates to spiral wind turbines and an energy-harnessing system. The system features a plurality of spiral wind turbines adapted to collect drag energy of moving vehicles and for converting the collected energy into electricity. The spiral wind turbines can also be installed for collecting air flow energy from heating vents on rooftops, smokestacks or similar structures. The system uses wind energy along with captured moving air or heated air energy for producing electric power using electric generators and storing same using storage batteries. The turbines are vertically rotating, and the method of attachment/installation will depend on the type of turbine and the location. The system allows federal, state, and local governments, as well as others, to generate electricity passively.

A multi-stage hybrid Darrieus-modified-Savonius (HDMS) vertical axis wind or water turbine (VAWT) for aero-hydro energy harvesting. The HDMS VAWT can continuously harvest fluid energy, including wind and water energy, provides excellent self-starting capability, has enhanced structural stability, and a high energy harvesting efficiency.

A water reservoir system for generating, accumulating, storing, and releasing electrical energy comprises a reservoir wall built in a shallow body of water such as a sea or an ocean with a height exceeding the outside water level by about 10-25 m, thereby defining an interior of the water reservoir. Excess electrical energy from other renewable sources of electricity such as wind, solar power, or supplied by a local power grid is used to operate water pumps to fill the interior of the water reservoir with water during times of peak supply of electricity. Water is drained from the water reservoir to the outside body of water and generates electrical energy by flowing over a plurality of water turbines, thereby generating electricity and supplementing electrical power for the local power grid during times of high demand. Additional interior sources of renewable energy may be used to supplement external sources of electrical power in operating the system of the invention.

A vertical shaft wind turbine that is superior in a rotational startability, even at a low wind speed, and is suited to a wind power generator that has high rotational torque. Each blade is an upper-and-lower-ends fixed type vertically long blade which is suitable for use as a wind turbine or a water turbine. The string length and thickness of an upper-and-lower-ends fixed type vertically long blade (8) that is fixed upper and lower ends to a vertical main shaft (7) gradually decrease from a main part (8) thereof to tips of the upper and lower inwardly curved inclined parts (8B, 8B), and a cross section of the main part (8A) is a lift type. A thickness of the cross-sectional shape is continuously and gradually thins from the main part (8) to the tips of the inwardly curved inclined parts (8B, 8B).

A floating heat pump system including a superstructure supporting a wind turbine and at least one electric generator mechanically connected to the wind turbine. Wind-induced rotation of the wind turbine causes the electric generator to generate electricity. The generated electricity may be supplied to a power grid, or a portion of the generated electricity may be used to power a heat pump also supported at least in part by the superstructure to extract heat from the ocean or another large body of water. The heat may be stored in transportable thermal storage medium. Heat stored in the thermal storage media may be used at the system or remotely for regional or district heating and cooling, industrial purposes, or to generate electricity.
