Insulation… OF TOMORROW

This is cool: recent tech advances have lowered the cost of making aerogel sufficiently that it can be used for home insulation!

I’ve written about his bizzaro stuff before: it’s a silica gel that has so many air pockets in it it is essentially barely more dense than air itself. It has a lot of uses, like putting on board spacecraft to catch particles from comets. But it’s such a good insulator that it may very well revolutionize the industry.

It’s been around since before the space program, so we can’t attribute this invention to space age tech, but it does have a lot of uses, and I bet as the price lowers people will find lots of other ways to use it.

I love living in the future.
