For a look at a piece of rather useless tech, see the
Microclimate Air.
$300 US for that?
What was that quote from Bored of the Rings? "
This is a rather sizable group, sporting the kind of scorchmarks on their pockets that only the spontaneous combustion of heavy wads of crumpled money can produce."
Edit: Found a
review of the Microclimate Air helmet.
