re: #85 Gus 802

It may work in the distant future but as an investment that would mean a multi-billion dollar project that would be unproven to sustain itself in the free-market. I see it as first having to prove itself with elevated track with some tunneling since that can’t be avoided. Once it proves competitive then they can consider other options. First you build an airline, then you build the fancy airport.

The cost would be astronomical,why not go up?

Its raining soup in space and we haven’t even invented spoons yet.

One small asteroid could supply all Earth metals for a hundred years,processing would be cheap,free solar energy,non polluting,transportation of finished product would be as easy as dropping it into the proper reentry trajectory.
