The active water hydroelectric system uses a hydraulic ram pump to increase pressure to turbine blades using water from a low head water source, the system comprising a housing, drive pipe, delivery pipe, pressure vessel, turbine, waterwheel, and first and second generators. The drive pipe is fluidly coupled to the low head water source and pressure vessel. A primary flow moves across a turbine turning a first generator. Primary and secondary flows turn the waterwheel which turns the second generator. The passive hydroelectric system a floatation device such as a ship or barge. A vertical siphon pipe and vector siphon pipe comprise a siphon mechanism that delivers water to the hydraulic ram pump. A primary flow of water flows from the pump to a drive pipe to the turbine. Primary and secondary flows of water turn the waterwheel. Water exits through an exit pipe.

The present invention is directed to a system for producing energy via use of gravity. The system is for generating energy, and in particular electrical energy, by utilizing the abundant force of gravity that exists and then integrating such a force into a system design of energy power generation by converting the force of gravity into potential energy then into kinetic energy and from kinetic energy back into potential energy again, by using the system's autonomous methodology of fluid recycling to produce electric power generation in the process.

Described herein are technologies of a heat engine that transforms a low-level temperature differential between a heat source and a heat sink into useful electrical power. One heat engine includes a hydro-electric turbine, a steam source configurable to generate steam from a hot water source, a condenser, and a slug intake bend in a first pipe coupled between the steam source and the condenser. The slug intake bend is configurable to receive a slug of water from a cold water source. The steam from the hot water source pushes the slug of water up a vertical distance to the condenser. The condenser is configurable to receive the slug of water and the steam and provide liquid water from the slug of water and steam to power the hydro-electric turbine.

A pumping apparatus includes a container positioned over a left column and a right column that contains a first fluid, left and right intake valves that respectively connect the left and right columns to the container, left and right pumps respectively associated with the left and right columns, upper and lower connecting pipes that connect the left and right columns below the container, a plurality of gates positioned at entrances of the upper and lower connecting pipes in each of the left and right columns, a turbine positioned to be driven by fluid flowing through the upper and lower connecting pipes, and a third fluid disposed in the upper and lower connecting pipes, and the left column and a right column.
