Has there been actual talk about using this in commercial rockets?

Imagine being able to store cryogenic propellants for months on end, either on Earth or off it.

The trick is choosing one of the many kinds of Aerogel. We can probably eliminate the common silica based gel because it shatters if you so much as fart in the same room with it.

Aerogel looks like a cloud and it's solid. It's the closest thing you'll get to whatever the stupid thing that OP wants

can aerojel be used to make optics?

Um have you watched any interview with him OP?

Hey /sci/, I've got a question for you guys. I'm usually on /k/ so sorry if some shit sounds stupid.

To start off, how buoyant is Aerogel? I ask because I want to increase the buoyancy of my plate carrier without increasing weight.

Assuming the plates are 8 pounds each (totaling 16 pounds) and 10 in. by 12 in., would 8mm thick Aerogel Insulation (cut to the same dimensions) on both sides of each plate provide proficient buoyancy to negate the weight of the plates? Additionally, if it affects it at all, I'd be coating the whole "plate assembly" with a rubber coating like Flex Seal or Plastidip so that the aerogel wouldn't get waterlogged, because I'm assuming it can. The whole thing would look something like this

Where X indicated rubber, 1 indicates aerogel, and P indicates the armor plate.

And finally, if aerogel isn't buoyant or for some reason wouldn't work, do you guys have anything that would?

Thanks /sci/

Does anyone know the average distance between the pores large enough to scatter light in SP-20 Aerogel, made by Matsushita? All I have found about the large pores is that their distribution depends on the chemistry used to produce the aerogel.
