The vapor pressure. Water ice would need to be cold indeed
to prevent it from being lost thru sublimation.

Well, right, but of course we as humans need not actually
ever be uploaded to continue with my notion of Earth-origin
intelligence bursting forth into the galaxy. It would be
nice of course, butuploading of a meat brain is a far more
difficult problem than building an MBrain.

Ja, but I have long since scuttled the notion of very many
humans living off this planet long term in anything much resembling
our current form. We have faaaarrrr too many wasted atoms.
Dont back away from it, Robert, your vision of an MBrain
is sheer brilliance. Do maintain ownership of that idea.
There is no need to assume we will do otherwise or colonize the
galaxy in any other form besides an enormous flock of interdependent
orbitting nodes. The more one thinks about it, the more inevitable
the Bradburyesque MBrain structure becomes. spike
