The disadvantage of your solution is the environment impact of such a transportation system. An electricity based solution seems to be much cleaner (especially if we imagine the same kind of traffic as the plane one today).

- marvin 14y agoLiquid hydrogen/liquid oxygen is the most efficient chemical rocket fuel possible. Most famously used by the Space Shuttle Main Engines.
