Orbital Levitation...
Hi All
Neat idea SM... but I'd rather the Space Elevator.
However I still think the NTR SSTO is the better option because it is doable and virtually realised technology [most of the hardwork was done in the 60s], rather than hard far-term tech.
In the end the SE, tethers and beanstalks will open the Solar System, but we need somewhere to go first. SSTO NTRs and high-speed Gas-Core nukes make that first stage possible.
