Great insight as to why we shouldn’t stop ramping renewables deployments. You need not only cover current electrical demand, but demand growth over time, transportation, HVAC, and all of the energy needed to sequester excess atmospheric CO2 emitted during human industrialization (>1000 gigatonnes based on 280ppm atmospheric CO2 pre industrialization and 420ppm current state).

Burning ancient sunlight is expensive.

Maybe it's a better idea to release massive amounts of N2 and O2 rather than chasing a 100ppm of CO2 here and there.

In, like, setting up petawatts of nuclear electrolysing plants that will split seawater into H2 and O2, where the gases will dilute the atmosphere enough that CO2 levels drop.

This harebrained idea is on par with those CCS projects, but has the nice side effect that the nukes can sometime later be repurposed to more useful things.

The nukes could run carbon capture plants. Or, even more directly, they could power homes, industry, charge electric cars, etc.
