That’s a Rube Goldberg device.
Very large rockets are more likely to work and be practical.
You can generate oxygen and hydrogen fuel easily...make the booster re-usable and the whole thing is pretty cheap to operate.
“Rube Goldberg”imp,lies senseless complexity.
While ‘startram’ may be a bad idea 9or not) the mechanism is almost as simple as the maglev trains which are in service.
If we don’t build this, the Chinese will. I guarantee it. And they will do it much faster than anyone would ever believe.
It’s about usable payload, getting mass in space, and doing something with it. Build a nuclear reactor to supply the power, run the tube up the side of a mountain to get as much acceleration as you can before hitting the atmosphere, and start throwing crap up into orbit. Each transport vehicle will be bolted to the space station, pressurized, and available for use.
This is something we should have done decades ago.
