I remember when Mark Evans worked on his Sally Lightfoot trimaran in one of these air buildings. Even on summer days it was bearable, to my surprise. It was high inside. I found these guys online http://www.websweeper.com/php/pool_domes/do-001.php
I’m impressed at the low cost.
I always wanted to do a portable house like this anyway.  http://blog.modernmechanix.com/2008/05/21/your-own-inflatable-dome-make-it-from-a-kit/?Qwd=./PopularScience/7-1973/inflatable_dome&Qif=inflatable_dome_0.jpg&Qiv=thumbs&Qis=XL#qdig

I wish they were still available.  I see it has plans, sort of… like I need another project.
