Patent ID: 8182688

Claim:
A biogas generator for converting liquefied organic material to gas and slurry via an anaerobic digestion process, the biogas generator comprising: a reservoir to hold the liquefied organic material; an inflow conduit through which the liquefied organic material is pumped into the reservoir; a gas outflow conduit through which the gas exits out of the reservoir; a heat exchanger positioned inside the reservoir to heat the liquefied organic material in the reservoir; a first pump connected to pump the liquefied organic material through the inflow conduit into the reservoir; a second pump connected to pump a fluid through a closed-loop conduit and through the heat exchanger; a solar power and heating system comprising one or more solar cells and a solar panel through which a part of the closed-loop conduit passes, the one or more solar cells converting solar energy striking the one or more solar cells into electricity used to provide power to the first and second pumps and the solar energy striking the solar panel heating the fluid traveling through the part of the closed-loop conduit, wherein: the heated fluid heats the liquefied organic material as the heated fluid is pumped through the heat exchanger to facilitate the anaerobic digestion process; and the one or more solar cells are electrically connected to a re-chargeable power source and the one or more solar cells convert the solar energy into direct current electricity used to recharge the re-chargeable power source and the re-chargeable power source is connected to provide power to the first and second pumps.
