Is this suppose to be more cost effective than a concrete channel operating at atmospheric pressure or existing fast trains? --- End quote --- It was supposed to be more cost effective than the existing California High Speed Rail project. That's the whole reason for the proposal. --- End quote --- California is not known for fiscally responsible rail projects. When they built BART, they selected a non-standard track gauge ensuring higher costs and then things got worse when they later needed replacement stock. |

Besides, with 3D printers having "changed the game" (how many times now?), I thought we could fabricate anything on demand... |

CON: Requires special facilities, e.g. start with less than full load of fuel and fill up after start from air tanker. CON: Cargo space designed for a few special cargo options, not for standard containers. |

Well, OK, if you want to be picky about it... You also need two big block Hemis to start the thing, but I don't see that as a CON either. :) |
