If I take a large but hollow brick of very light graphite foam, and
paint it in vacumm with a very thin layer of very light airproof paint,
would this brick be lighter than the air? Would it act as a hydrogene
baloon? With bricks like this, would it be possible to build an object
that floats in the air? |

you might be interested in the thread "Vacuum building" i had a while
ago in alt.sci.nanotech. i wanted to build a carbon sphere with a
vacuum within.
