From George Woods
I was taken aback by the Klaus Lackner plan to strip CO2 from the atmosphere by wafting air across CO2-absorbing chemicals such as calcium hydroxide. As the only viable method of making calcium hydroxide is by heating calcium carbonate – usually by burning fossil fuels – and driving off the CO2 into the atmosphere, the scheme is apparently a multibillion-dollar method of increasing the level of CO2 in the atmosphere.
