OK, thanks. So how about I use strong carbon fibre shell with air pumped out. There is no lighter than air gas involved and the whole machine can be (just slightly) heavier-than-air. I bet they would outlaw that too, under the 'catch all' rule mentioned below. Nothing but extremely hard work will do ;)
- leoedin 14y agoIt'd have to be a very strong shell to actually give you buoyancy above simply not having anything. Carbon fibre is strong in tension, while a material which can support a vacuum must be strong in compression. The weight of any shell is going to be much greater than the buoyancy you'd gain.
