You keep saying climate policy is based on politics, but you are not providing any evidence of that. Please provide evidence of your assertion this is political. You argue that "there is nothing technological stopping this except economics"; that means it isn't feasible unless proven the economics will improve. A proof of concept does not guarantee scale.
