Hi Graham:

Interesting concept but i guess uber-expensive to build. However you should also be interested in this other tube concept: The Toronto Cycling tube.

See: http://www.thecoolhunter.net/design/CYCLING-TUBES---TORONTO/


Cool idea. I wonder how a concept like this would get off the ground. You'd think people with high distribution costs would be really see the upside - an Amazon for example.

(BTW, we met in Dallas a few years ago and its been great following along with your latest venture and hearing about your Rails experience).

Cheers, Gavin.

Pets. And children. And small, very flexible adults. With the addition of a packet anonymizing filter, or maybe some packet spoofing hacks, it would be a great way to dispose of body parts (Honey, did you order a leg from the grocery store?) Or make, heh, anonymous deliveries.

Instead of using canisters, why not use balls? They could easily roll, may be less likely to get stuck in a tube, could reduce energy costs by being gravity fed, and could also be more easily sent via "airmail". Imagine vast arrays of "repeaters" that function like the machines that sling baseballs at you in a
batting cage. They could be mounted on rooftops where the costs of tunneling underground are too high and work seamlessly and dynamically with a subterranean system to route items depending on dynamic decision making about cost, weight, energy consumption, etc.

Now that's an abstraction on steroids! :)

Interesting idea. However, we still need a separate transport mechanism for energy and I'm not sure I'd want my milk delivered in the cannister the Smiths next door used to dospose of their sewerage!


This sounds like a modern version of pneumatic tubes:
