This is also a good example of biomimicry.
All that is said about aerogels are true, but don't hold your breath getting to the cheap part.
I would love to have a 10 cm thick aerogel insulation in my house, it would be more like a meter of fiberglass but right now aerogel coats cost about 500 dollars and up.
And that is for just a maybe a square meter of the stuff. For a whole house, it could cost a hundred thousand just for the insulation, at least right now.
