The only hope now is exponential growth of (solar and wind)+batteries making other sources uneconomic. This seems to be slowly happening, so I hope we hit the exponential curve soon and we're there quicker than we expect.

This only stops it.

Then, to fix it, we'll need a massive Direct Air Capture industry that will have to operate for a century, and probably past that so we can hit and maintain a CO2 level of 250ppm.

This has nothing to do with this at all. We're talking about 4th grader literacy nationwide and you're talking about algebra in a single area in a different grade!?

The second point where there aren't enough teachers nationwide (10% missing workforce) is probably because teachers are terribly paid, disrespected, and subject to bad working conditions.

Maybe that's why people aren't clamoring to be teachers and the quality of work is low?

This really does help break any feeling of attachment to the device and the solutions in this post really do make it more practical. It does kind of suck using the camera in grayscale.

The requirement to do so is in our constitution, the Charter. It's not optional and not absurd to anyone with proper historical understanding of Canadian history.

Ironically for this thread, I think an AI redesigned website would do wonders here.

A huge synthetic telescope in orbit with an aperture the size of the planet?

How many private earth observation satellites?

The market is huge when weight constraints largely go away and $/kg drops so hard.

Reusing Apollo-style stack, reusing Shuttle engines, reusing Shuttle-style SRBs. Novel?

> equals the value of what they give to the tax payers in return

This seems incredibly shortsighted.

Anywhere on earth is better than space for this application.

Don't be so sure.
