A modular pump system permits combining multiple discrete pump assemblies in serial and/or parallel configurations to tailor system output to user needs. The assemblies may be combined by hand quickly, without the needs for tools, to permit use in remote areas.

A system for supplementing the electric power needed by a pump jack electric motor, thereby reducing the electric power purchased from the local utility or power supplier. The system comprises a solar photovoltaic system, or other forms of renewable energy, and regenerated power from the electric motor or drive. The system can be both on-grid and off-grid. Battery banks and capacitor banks may be used to store energy.

Example embodiments relate to a water feature. The water feature includes a vessel and an electrically powered submersible pump within the vessel, an outlet fluidly connected to the pump, a solar panel, and a battery. The water feature also includes a controller, a processor, and a non-transitory computer-readable medium which stores a set of program instructions which cause the water feature to perform operations. The operations include receiving a predetermined time to operate the pump on the battery. Based on the predetermined time, the operations include allocating a percent of a total electrical power generated by the solar panel to charge the battery and a remainder of the total electrical power generated to operate the pump. The operations additionally include determining that the battery has reached a threshold power level associated with the predetermined time to operate the pump and allocating the total electrical power generated to operate the pump.

We have described herein a method and associated apparatus that can halt global warming with significant economic benefits. They include (1), re-scrub half the carbon dioxide emitted from calcining baking soda into soda ash to produce twice as much soda ash and twice as much ammonium chloride as comparing with the standard Solvay ammonia soda ash process; Use the ammonium chloride as sugarcane fertilizer producing fuel ethanol, and bagasse, a photosynthesized bio-fuel from carbon dioxide already presented in the earth atmosphere for power generation, and (2), expand the sugarcane plantation areas into desert oasis using desert heat to produce distilled water for irrigation, pumped by solar heated hydraulic press pumps to supplement insufficient rain forest resources on earth's continents to accelerate reaching carbon neutral on capture annually twenty five billion tons of anthropogenic carbon dioxide from earth atmosphere economically.

Embodiments of the present invention are directed to a water pumping system. More specifically, embodiments of the present invention are directed to a solar electric powered, siphon-capable water pumping systems specifically configured for use in rooftop and other applications having similar need and conditions. Advantageously, a water pumping system configured in accordance with an embodiment of the present invention is configured to prevent pooling of water in low-lying areas of a roof and thereby limits the potential for damage to the roof and underlying structure that could otherwise result from such pooling of the water.

A pumping device for liquids is described which comprises a tank for liquids, from which a feeding pipe of a pump with a solar panel draws. The tank consists of a supporting frame with tubular uprights and upper and lower horizontal connection lengths, which supports and surrounds a flexible bag for containing liquids and has an upper connection crossbar of the upper horizontal lengths of the supporting frame, on which the pump with solar panel is mounted. The bag has a lower filling hole or mouth, in which the feeding pipe can be inserted and an overflow hole made in the upper of part of its side wall in position lower than said mouth.

A pumping system and a pumping method implemented with the pumping system. The pumping system comprises a solar panel performing a photovoltaic conversion based on an insolation level including a first insolation level and a second insolation level; a fuel reservoir containing a fuel in a liquid state; an electric motor; a pump rotatable by the electric motor to pump the fuel; and a first motor drive converting electrical energy supplied by the solar panel to drive the electric motor at a first speed when the insolation level is at the first insolation level and at a second speed, slower than the first speed, when the insolation level is at the second insolation level, thereby pumping the fuel at a first rate and a second rate, respectively.
