DETAILED DESCRIPTION - Rotating, synchronous reaction cell has a centrifuge, a generator, a water heater, a gas-trapping pocket which encloses a water heater, a centrifuge, a hydrocarbon synthesizer and a condenser bed. The reaction cell mixes gas with carbon in cyclic flow through catalyzing bed, separates liquid from gaseous reaction product and to obtain liquid product, and expands steam through a turbine to rotate and turn generator. The rotating unit and its stationary support are mounted on a tower which uses solar energy for processing heat. The centrifuge accelerates water, whose interior primary resembling a thin cylindrical-shell void having a circular array of vanes extended from the outer radius to the inner radius of the cylindrical shell void, and from the top radial plane to the bottom radial plane of the cylindrical shell. The vanes accelerate water or other fluid within the centrifuge. The centrifuge is used as water heater by applying heat to the cylindrical outer-radius exterior surface of centrifuge. The heat is solar energy which is transferred to water bearing against the inner-radius interior surface of the outer-radius containment wall of the water heater. The water heater transfer heat to the water inside the water heater, and raises the number of water molecules having sufficient energy to disassociate into hydrogen and oxygen according to the Maxwell distribution of energy. The hydrogen gas in the centrifuged water is driven inward by induced buoyancy, as compressed water which is heated in the water heater and centrifuge channeled through a circular plenum to a turbine where steam expands through the turbine. The turbine causes rotation of the water heater and the centrifuge. The stacked array of gas-trapping pocket collects hydrogen gas. The gas-trapping pockets are narrow annular void divided into a circular array of smaller cavities by vanes disposed in the interior. The pocket has interior surface formed using hydrogen-permeable material and hydrogen-selective membrane material. The hydrogen gas trapped by buoyancy in the gas-trapping membrane pockets permeates through the hydrogen-selective membrane material, is entered into a gas inlet of a hydrocarbon synthesizer. The gas-trapping membrane pockets enclose the gas inlet at the outer radius. The hydrocarbon synthesizers, water heater, centrifuge and turbine rotor turns at the same angular speed as assembly. The hydrogen gas entering into the gas inlet of the hydrocarbon synthesizer is mixed with injected carbon at the entrance of a compressor. The hydrogen gas and carbon passes through the compressor which mixes and pressurizes the reactants. The pressurized mixture of hydrogen gas and carbon is channeled into condenser bed(s). The condenser beds having multiple, cascading layers of screens is secured in tension by the rigid frame of the condenser bed. The rigid frame has a matrix, and grid or honeycomb of smaller sieve pockets penetrating the radial distance through the rigid frame. The screens are coated with platinum-group catalyzing metals. The catalyzing material of the condenser beds carries out various reactions of hydrogen and carbon within the sieve pockets of the condenser beds. The products exiting at the outer radius of the condenser beds are channeled into an adjoining liquid-gas-separating centrifuge where the products are segregated by density, such that gaseous hydrocarbon molecules and hydrogen gas are drawn out from the centrifuge into the low-pressure inlet of a recirculation blower disposed at the inner radius of the liquid-gas-separating centrifuge while liquid hydrocarbon molecules and fine carbon solids accumulate in the liquid-gas-separating centrifuge. The recirculation blower exhausts the gaseous hydrocarbon molecules and hydrogen gas drawn from the liquid-gas-separating centrifuge, into the gas inlet of the hydrocarbon synthesizer. The exhausted gaseous mixture combines with hydrogen gas permeated through the hydrogen-selective membranes. The blended gas stream entering the compressor mixes and pressurizes hydrogen and carbon before channeling the mixture into the condenser beds. The float valves are disposed in a circular array around the interior surface of the outer-radius containment wall of the liquid-gas-separating centrifuge. The float valves have an effective density and spring force with respect to liquid hexane. The exhaust ports allow liquid hydrocarbons and carbon solids having a density greater than hexane to exit the hydrocarbon synthesizer. The electric generator is connected to a shaft emanating from the rotating unit, and motor-generator.
