Evacuated Air Transport

[Joseph Bento]

Is this an upcoming broadcast?  I hope they provide you with a copy, as 
I'd love to hear it.  Iain corresponded, and mentioned the tubes used to 
carry cash, receipts, etc at banks and department stores.  They are 
still widely used here.

It would be interesting to see what sort of seismic protections a 
transport tube would need.

Yes, it is likely within our technological ability for a Transatlantic 
tunnel.  It would probably have to be limited to high speed rail.  I 
wouldn't think personal autos would be practical due to distance, fuel 
demands, accommodations,  not to mention accidents!

Although the science is sound, the engineering problems are significant - the vacuum in the tube would have to be pretty good, and if it fails while the capsule is travelling at 4000 mph, things are going to get very hot, very quickly. Air friction would be significant at that speed. The capsule will also need a good independent air supply too. I wouldn't be queueing up to ride on the first one - the hazards are not that different from space flight.

It seems nearly unbelievable that one could traverse the country in about the same time I take in my morning commute.  If the cost estimates are accurate, it might seem there should be full funding for this project.
