A material that weighs less than air?
« on: January 07, 2010, 10:36:34 PM »
Material that weighs less than air?  ???
Here a new idea ;D
Synthesize fullerenes or nanotubes ... And helium or hydrogen inside  :-*
Airgel like material --- but much lighter and stronger to build ...
A floating structure or vehicle?

Who can pass it to try it?


 ??? :o

Why should one add helium or nitrogen? If a buckyball is empty the buoyancy will be greater.  ;D

I love bucky balls, so perfectly symmetrical in every way.  I wish there was a woman out there like a bucky ball.  Full on tetrahedral look.  ;D

Hehe, I love chemistry jokes.

But back to the topic. It sounds like a great idea, but I would imagine that the production costs would be immense for building a vehicle or structure. Not to mention that this would essentially be the Hindenberg all over again.
