I find it curious that you continuously dismiss terrestrial solar
which favoring pie-in-the-sky solar, which is exactly like ground
solar, but more centralized, more difficult, more expensive, and
has a worse EROEI.
I absolutely can see how we can start producing SPS in 50 years,
when we start starving the ecosystem of sunlight, but that time is

We don't have the money, the time, the resource base.
What I hope will happen is scalable, modular synfuel from hydrogen
to methane, methanol, and other synfuels, under relatively mild

Don't forget coal. Getting rid of coal, and oil, and after that,

exhaustion a short while ago? And deploying IPv6 is *easy* in
