    this should lead to better cost-effective insulating material for homes and reduce heating/cooling bills;

    "...Aerogels are an amazing material - safe, light and ten times more insulating than what we are using now - but until now they have been out of reach for the majority of us because they are so expensive to make. Our research is a step towards making them widely available...
    ...
    Aerogels were first discovered in 1931. Typically weighing around 0.1g/cm3 and made up of 95% air, they have a thermal conductivity similar to a vacuum panel making them ideal insulators - not just to keep warmth in, but also keep homes cool."

    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.
