How to fly on nothing - The future of air travel

1 decade 1 year 2 months 3 weeks ago

Published on Jan 26, 2013
So how do you fly on nothing, nothing at all? The answer is kind of tied to the cliffhanger from my last video (http://www.youtube.com/watch?v=cgGghuA2r78 ).

Turns out the most buoyant thing you can put in a container is nothing, absolutely nothing. A vacuum! So a vacuum balloon would be more buoyant than either a hydrogen or a helium balloon!

So why haven't we made one yet? Well it turns out that making large light vacuum containers is technically very challenging. It certainly hasn't been possible to date, but its my reckoning that with modern materials, it should be possible to create a vacuum balloon. Further I just think it would be sooooo cool to actually have a balloon that floats on nothing... quite literally nothing!
