For a guesstimate of pressure, check out http://www.nanomedicine.com/10.3.html
Robert's example: a 1-micron spherical tank with 5 nm (~30 C atoms) thick
walls can hold 1000 atm with a safety factor of 5 (if the walls are as
strong as diamond). Pressure is directly proportional to wall thickness and
material strength, and inversely proportional to radius, as shown by

Is your paradigm shift automatic or stick?

is that he's right, unless Gina Miller steps in and says otherwise. If
you want to take this further, we can do it in private, or, if you must
have a public forum, on the Extropian mailing list. I don't know why
you're doing this, but it is not the business of the nanotechnology
discussion list. End of thread.
