We need a 300mph train/mag lift/vacuum tube to replace domestic air travel.

Hourly stops from DC to LA, room for bicycles and wheel chairs, and trains run every 2 hrs or 1hrs during commute hours.

Also use centers of interstates if possible to avoid taking land via eminent domain.

1. Piece on CBS this am about how turbulence problems will increase with climate change

So I must pause before I write this off as will never happen. What is concerning is the drawings seem to show a small claustrophobic seat with no bathroom facilities...

3. That won't replace commercial air.

300 mph ain't bad, but it's too slow for coast to coast, that's over 9 hours from NYC to LA, with no stops. And we would need a HUGE network of such trains to effectively replace air routes.

4. Earthquakes could be interesting

I would like to see a budget version, where you are sedated and shipped in a small box. Amazon could do 2 day Prime delivery for $199/year.

8. We won't get nice things

10. The biggest advantage of trains over planes is that trains can be electric.

Planes must burn fuel.

Electric trains don't require fossil fuels or expensive synthetic fuels.

11. Also Japan has a functional system, and putting 200-300 in an Aluminum tube is breaking down.
