Where is that power coming from, that they use to get the carbon out of the atmosphere?

In a perfect world, from renewables and perhaps nuclear. But we should get to a point where we can use renewables to get rid of coal and natural gas generation, rather than using even more renewables to partially undo the harms of coal generation.

It's great to prototype capture... but the benefit is developing a technology that will mostly only be useful after largely decarbonizing the economy.
