Not all carbon sequestration requires input energy from the grid. As an example, one of the projects that Stripe is funding is https://projectvesta.org/ https://projectvesta.org/, which distributes olivine, a volcanic rock that absorbs CO2 to become limestone when it is eroded. By moving this material to beaches, wave energy can be harnessed to remove CO2

Ah, simply crush billions of tons of olivine and move it to a beach. Weathering olivine doesn't scale, because you need so much. It involves hitherto unprecendented amounts of quarrying and then transport. The quarrying would destroy massive amounts of habitat. After the waves do their trick, near-shore habitats would be devastated because the entire ocean floor is covered in olivine. I am a former geophysicist by the way. While I did not work in geoengineering, I am familiar with most of the serious proposals with scientific support. Be skeptical of these groups that claim to have an easy answer. I can tell you that no one in the field thinks carbon capture from the atmosphere is realistic anytime soon. The scale is enormous. Most people have trouble understanding the difference in scale with what we actually have the capability for.

  Once people realize the true impact of climate change they are going to be desperate enough to attempt anything that even shows a tiny glimmer of hope. The only problem is that some people pretend that this glimmer is a guaranteed solution.

    There is a guaranteed solution to stop it from becoming apocalyptic which is comparatively easy and cheap, and we know it would work: just move away from fossil fuels and carbon intensive production ASAP. This requires political will we don't have, and fantasies like this just distract from what is necessary and the steps we must take. These kind of pie-in-the-sky things takes money and attention from real solutions that work. They are false hopes that make people complacent and the problem seem less urgent, thinking that we'll tech our way out without fundamental changes to how we live on this planet.
