Claim:
1. An apparatus for producing methane from carbon dioxide comprising: (a) a deep well bioreactor comprising an elongated cylindrical shaft having an upper end, a lower end, and an interior, wherein a substantial portion of the deep well bioreactor extends vertically below ground level; (b) a biomass contained within the interior of the elongated cylindrical shaft, wherein the biomass is exposed to pressure greater than atmospheric pressure, and wherein the biomass is adopted to uptake carbon dioxide and produce additional organic biomass by photosynthesis and including fluid outflow; (c) a light system for enhancing carbon dioxide uptake located within the bioreactor; (d) a digester operably receiving the fluid outflow from the reactor and converting organic biomass within the fluid outflow to methane.
