Officially "Awesome" because Frotter said so!

So if my thick air mattress (honeycomb cell) is comfy & warm in pretty extreme conditions, what's to stop a well formulated technical inflatable layer of insulation for temporary buildings, or spaces where removal of insulation may be required for access, why do we not make inflatable HWT jackets etc that can squeeze in where wall & tank proximity is slim, yet expand (due to pressure obviously) around less encumbered areas?
say for temporary site offices, or as a heat reflective wall for single skin buildings, or am I simply barking up the wrong tree?

..never been the same since I saw an inflatable KFC in Bulgaria many years ago.   facepalm Grin

Surely there's some useful, viable applications? what do you reckon you could get a decent performance from? ..I googled it & apparantly theres an Australian professor?? who has inflatable "supports" for secondary glazing in  rental properties..
got me thinking, thats all, ...if it's good enough for a warm nights kip then what else!?

The other thing that got me thinking was based on a recent bit of newspaper reportage which stated that 1/3 of US forces mission costs overseas (ie afghanistan / Iraq) was wasted away on air conditioning, makes me question what they're doing it really does!

What could a bunch of roll out solar arrays do for "temp" camps (of 10yrs) for general power & cooling requirements of computer equipment, offices sleeping quarters etc etc.. either keeping cool air within the wall structures of inflatable inserts & heat out or heat in depending on how you layer it!?

now, someone shoot me down!  wackoteapot or theorise as to ways round this that are efficient.
lets just say for example that if 1/3 of 20 billion was spent on existing tech air con what then whatever you come up with is potentially small fry even if it seems outrageously costly.

I think the issue is not so much having an air layer, it's trapping the air in small enough pockets that it can't convect around and transfer the heat away. Look at it like this, in the attic you've many feet of air above the ceiling, but it needs a thick layer of something like fibreglass to keep the heat in - the fibreglass traps the air in lots of small pockets and prevents it convecting all the heat away.

But, as you say, if well designed then an inflatable multi-layer, small pocketed, jacket would well be of use in some situations.
