Prototype Inflated

5' prototype inflated.  My living room is now *much* smaller.

The ridges will support the mylar mirrors.  I'm only covering 40% of this prototype w/ mirrors.

 

This is the nozzle of the latex weather balloon w/ a PVC check valve installed.

And here is the access port that lets me reach inside while the balloon is partially inflated.  On the full size balloon I may be crawling through it.  The closure is lace-over-zipper w/ a flap on the back side to protect the balloon from the zipper teeth. 

 

Last step is installing the mirrors...
