One thing I find interesting is that 'aerogel' is a category of materials. I thought it was reserved for the silica based aerogel i've seen countless news stories about. The wiki definition is "Aerogel is a synthetic porous ultralight material derived from a gel, in which the liquid component of the gel has been replaced with a gas". Theoretically, you could market fiberglass insulation as 'Aerogel insulation' if you suspended the glass fibers in a gel and then replaced the gel with a gas. The result could have worse insulative properties that standard fiberglass and yet technically be an aerogel.
