Gravity generator-assisted photovoltaics

The invention increases the efficiency in the conversion of sunlight into electrical current by means of photovoltaic solar cells (1) known from the prior art, with the inventive inclusion of further known system elements, such as water electrolyzer (4), fuel cell (7) and gravity generator (water turbine (9) with coupled power generator (10)) in a system network according to the invention (closed circuit filled exclusively with hydrogen (5) or oxygen (6) and water (8) connecting lines, which can be rigid or flexible, which also incorporates the inventive use of gravity by means of a generator (10) coupled to a water turbine (9) for electrical power generation.

This object is achieved according to the invention in that sunlight, via a solar cell (1) which emits electrical current, breaks down relatively heavier tap water into specifically lighter hydrogen and oxygen by means of a water electrolyzer (4) located at a low level in the earth's gravitational field, which is recombined into water at a high level far above this by means of a fuel cell (7) with the emission of electrical current.

Since the water-emitting fuel cell (7) is located according to the invention far above the water-splitting, gas-producing electrolysis cell (4), in buildings (houses, towers) in the 100 m range, in earth boreholes (aesthetic advantage), in topographical terrain or in the sea or suspended from a tethered balloon several km, the earth's gravity field results in a

weighty water column (8) in which the pipe (8) (rigid or flexible) connecting both cells (fuel cell (7) above, electrolysis cell (4) below) shortly before the water enters the electrolysis cell (4) converts the potential energy gained by the earth's gravity by means of a water turbine (9) which is also suitable according to the state of the art and which converts small amounts of water at extremely high pressure with a coupled power generator (10) into electrical current.

A control and adaptation unit (black box (3)) already known in the state of the art regulates and controls the photocell (1), the electrolyzer (4), the fuel cell (7) and the power generator (10) driven by the water turbines (9) via a network of electrical cable connections (2), again in a closed power network (2) with the possibility of decoupling the electrical current (12).

Although all system components involved have only known, limited efficiencies, the combination according to the invention makes it possible to increase the electrolyzer (4) located at the bottom in the earth's gravitational field (11) to the fuel cell (7) located at the top in the same field (11) under the constant influence of gravity (11) on the water column (8) whose size can be influenced thereby and thus its potential energy to an efficiency-increasing electricity output up to efficiency one by means of an optionally large influence on the level difference.

It goes without saying that only system components with known highest efficiency as well as optimized inner pipe walls with corresponding cross-sections with lowest flow losses (hydrophobic), as well as electrical cables with lowest ohmic resistance (superconductivity), etc., should be used.

A buffer battery is integrated into the black box (3) to bridge the photocell (1) in the absence of sunlight.
