    Yeah no country has ever built a high speed passenger rail network interconnecting cities spread throughout an area comparable to the usa. And it’s absurd to think that it could be done in under 20 years and receive massive popular support and have universally recognised benefits. Guys the cost is too high for the biggest economy on earth and the distance is so far that they could never build a railway across it especially not more than 100 years ago.

    (Well to be fair the Chinese did also build the railways across the US so maybe they do have something America doesn’t)



  • Okay I’ve had this astroid mining concept dining around my empty skull for a while now. The way I see it is that going up to space and mining an astroid for minerals and then bringing them back down to earth will never be a worthwhile endeavour. If you’re mining them in space and using the material manufacturing in space then that seems more plausible. The only way I can think of planetary based astroid mining being worthwhile is if instead of mining the rock and sending it down in crafts, you just bump the astroid so it’s on a collision course with earth and then mine whatever is left from impact. In anycase, I’d say we are far off being able to mine asteroids since imo, the only worthwhile way to do it is by having the entire process in space. And we’re not even close to that level of infrastructure existing in space.
