This stuff is pretty neat. Back in college, my aero engineering roommate showed me a video of a crayon sitting on top of a sheet of aerogel thinner than a pane of glass with a blowtorch underneath. An enormous amount of time passed, and the crayon was unmelted. It was pretty neat. Back then, the challenge for home use was the bluish tint that would make it unappealing for windows. That and the fact that people who care about home heating costs don't have bajillions of dollars for space age insulation. I wonder if either of those problems have been solved.
