I've been interested in aerogels ever since I read about them. Unfortunately,
I know very little about them. Perhaps someone on the net would be so kind
as to post a little basic info about them? As I recall, they are rigid, and
transparent, of very low density, and able to support masses many times 
greater than their own mass. The problems seem to be high cost of manufacture,
and instability in the presence of moisture. Correct so far?

Has anyone succeeded in encasing aerogels in membranes to keep out the 
moisture? Is it possible to construct an aerogel that is lighter than air
by using hydrogen or helium? What are the mechnical properties of a typical
aerogel? How does an aerogel respond to being crushed?
