A system uses thermal solar energy coupled with microwaves and plasma for producing carbon monoxide (CO) and dihydrogen (H2) from carbonated compounds (biomass, domestic waste, sludge from waste water, fossil coal), wherein the obtained gaseous mixture yields, amongst others, hydrocarbon fuels (olefins, paraffin), esters, and alcohols via a Fischer-Tropsch synthesis. In a first step the carbonated compounds are roasted and pyrolized to produce char and dry coal, and a mixture of superheated gases containing CO2, steam, tars and non-condensable volatile materials. The method includes in a second step, and from the pyrolyis products (char or coal, gas mixture), generating a syngas substantially containing a mixture of carbon monoxide and dihydrogen, the mixture being used in Fischer-Tropsch synthesis units. After the Fischer-Tropsch step, the synthesis products are separated in a distillation column after heating in solar furnaces of mixed furnaces (solar / microwave).

Solar desalination system with reciprocating solar engine pumps
A solar desalination system includes a solar furnace for receiving seawater into a vessel and concentrating sunlight on the vessel to heat that water using solar energy to create desalinated steam. Water is input into the furnace via a pump that is powered by a reciprocating solar engine. The reciprocating solar engine includes a seesawing platform with a closed system of two or more connected containers thereon. Solar heating causes a fluid to move from one container to another causing the platform to reciprocally rotate through a predetermined arc, creating energy that can be harnessed. A riser pipe extending upwardly from the solar furnace carries steam to an electric power-producing steam turbine generator where the steam generates electricity. A drop pipe extending downwardly from the steam turbine generator carries desalinated water to an electric power-producing hydroturbine generator where the water generates electricity and is then removed for subsequent use.
