Every photosynthetic organism you see around you is a carbon capture device, that operates on low levels of solar energy. Want to capture carbon? Work on biomass. These ideas about scrubbing diffuse CO2 from the atmosphere are maddeningly wrong-headed, on every level. We already have plants capturing the CO2 for us, without any intervention on our part. Why do we need to cover land with machinery to do the same job, with a lot more energy inputs? Ridiculous concept, and this article should have included the energy inputs for producing the machinery and for operating the machinery. The dollar figure per ton of CO2 removed is not a very useful metric, and the energy inputs would have revealed that it is a pointless exercise in futility to try to power this machinery using fossil fuels. You'll never pull more out of the air than you produced to make the energy to run the mach...
