I'm continually surprised that this idea gets so much traction. While possible to build, it's also strictly Temporary and just leaves us with a worse problem later on. We'll just need a bigger one, 20 years down the line, when CO2 levels keep going up! At some point, it's pretty obviously a non-solution.
Let's put this energy into Nuclear Power and CO2 recapture; and actually fix things.
