My science background is quite limited also, so to elaborate is a bit difficult, if not nearly impossible. However, in another investment of mine, we are currently in VERY positive testing stages (with VERY big names, I might add), whereby the CO2 is injected into the soil of farmland, and acts as a fertilizer of sorts, adding increased productivity per acre.
It becomes a win-win-win-win situation. In time, we believe, we will get paid for first, the removing of CO2 from power plants, to second, the farmers. Farmers get increased productivity (the 'third'), and fourth, we get extremely handsome ROI royalties.
(The 'principles' in this non-public venture range from distinguished ex-P&G management, to world-reknown university professors in agriculture, to BASF, Monsanto, Dupont, Bayer, and other lesser known agricultural product manufacturers/suppliers).
