You know, the lowest hanging fruit right now isn't even energy generation. It is on insulating/ventilation of buildings. Despite that all the action is on energy generation, and for good reasons. The only of the low hanging problems that we really solved is illumination, and that took many years after we got a solution that was better than the older tech on every single way.

The same way, we can't wait for the generation problem to be solved before we start exploring the solutions for capture. We have to do everything all the time; just not with the same intensity.
