Curious, wonder why its used in packaging to evacuate air in preservation?

And why would this be? one central light source is one power consumer,
multiple light soures seems redunant...
Fibre Optic lighting eliminates infra red (heat generation) and UV (fading
of materials / dyes, breaks down some materials and tires the eyes)
Fibre optics channeling in sunlight from outside provides balanced lights,
again without IR and UV. No light bulbs, even longer lasting gas type rather
than filament, is just one more thing to produce and store up somewhere

Plasma screens are perhaps better than CRTs, but who would pass up 3d
instead? 3 dimensions of information rather than single flat view.
Even now, folks enjoy 3d virtual googles. Because of the psycological
limiting space of a space station, regardless of size (other than that off
another Earth :-) I would guess that people would look for any subtle ways
of cheating limiting dimensions.

I think that slip was actually prophetic, a rock passing through the
atmosphere of the living area of humans should probably be called a meteor
as well.

:-)

I keep thinking of the snip " 50% of jobs 10 years from now have not been
created yet" How will that deal with a project that is a best 20 years
away?
