Perhaps we should resurrect the old proposals for underground tubes
linking major cities. The tubes are denuded of as much air as possible
to lower resistance and mag-leve trains are run in them. If it could be
made to work the cost after building the system would be substantially
less per passenger/mile and the velocity attained would be much higher.
Any thoughts on what (besides all the environmental roadblocks) is wrong
with such an idea?
