Abstract: An apparatus provides for a method of converting solar energy into a synthetic carbon fuel. Solar energy is separated into different spectral portions and each spectral portion is directed to a plurality of photocells tuned for that specific spectral portion. The photocells convert the solar energy into electrical energy which is used to produce hydrogen gas through the process of electrolysis. The hydrogen gas is then mixed with carbon and various catalysts in order to cause a reaction which produces methane or other useful carbon based fuels. A cooling system filled with coolant oil keeps the photocells at a reasonable temperature while simultaneously providing the heat necessary for the chemical reactions that produce the synthetic fuel to take place. Carbon may be supplied to the apparatus by directing CO2 exhaust or output of a carbon producing power generator such as a coal-fired power plant directly into the apparatus.
