If a piece of aerographite were to be sealed on the outside, and all the air removed, then yes, it would float. But without this treatment, the air permeates the microstructure, and it does not float.
- kps 14y agoSo, the question is — if you take a zeppelin-sized chunk of aerographite, seal the outside, and evacuate the air, will it hold up to the pressure?
- ph0rque 14y agoYou don't even need aerographite for that: http://www.dangermouse.net/gurps/zeppelin/vacuum.html http://www.dangermouse.net/gurps/zeppelin/vacuum.html However, you need a material strong enough not to implode due to the outside pressure of air. Not sure how good material tech is for that. Even if it were strong enough, you would have constant "leaks" of air into the vacuum cells. So you would need a vacuum pump working all the time. Still might be worth it, though.
