Half a ton of Lithium-ion for comparison is 50-100kWh of storage. Which actually isn't that crazy. A Tesla per person per year, give or take.

Depending on the lifetime of the batteries, it's probably not far from what it would actually take to switch over to renewable energy while bringing the rest of the world up to a western standard of life.

But you're absolutely right that it's nonsensical to harvest carbon from the atmosphere while you're still pumping it in. That's product design driven by PR, not engineering.

And that points to the rest of it being bullshit as well.
