Ok  all you smarty pants Vanagon owners, you've seen it used by NASA,
and now its your turn.

Just drop a few k on some aerogel samples now being sold by United
Nuclear. Go on, line the walls with stuff, it has a nice high R factor,
fireproof and weighs only 3 times as much as air.

Take a look: http://www.unitednuclear.com/aerogel.htm
