Abstract: What has been created is a plurality and a variety of processes and a variety of devices correspondingly supportive to each process, wherein, a new partnership between; (1) a heat absorbing radiator compressed air pipes/tubes and (2) a gas turbine engine or a reciprocating piston engine,—is used to recapture and reconvert the, otherwise wasted, heat energies expelled by engines, by factories, by smelting plants, by distillation plants, by chillers/coolers/freezers, by cooking ovens, by lamps/stoves, by trash burners, and the heat energies created by the solar heat on the desert/ocean water,—into electric power and finally into hydrogen-deuterium fuel,—by having the engine's tailpipes submerged in cold compressed air inside the heat absorbing radiator pipes in reverse air flow, to further drive and re-drive the same engine; wherein, in order to capture fusion heat energy the hydrogen bomb is detonated in the deep ocean to catch the flames by the water and the hot water is used to energize the compressed air in

Abstract: What has been newly created is an apparatus that minimizes usage of the clean drinking water that has been hauled from a distant river/source, and maximizes usage of a low-grade water, such as subterranean water, sea water, recycled water and rain water for low-grade functions, such as toilets, firefighting, irrigation, etc, that are readily available near/within habitation communities that are totally dependent upon a public water,—in the form of an assembly of pipelines for low-grade water supply into the toilets of facilities/buildings/houses that is made separate and distinct from the usual clean drinking water pipeline in the house, wherein, a water deep-well is constructed under or within the yard of the houses/buildings or facilities/parks serving a water source for the low-grade pipelines, wherein, the low-grade pipeline is also connected to a municipal recycled water,—in order to prevent the clean drinking water from getting into the toilets, wherein, low pressure low-grade water tanks are installed
