Does anyone know of a lighter than air project that uses evacuated or at least partially evacuated containers for lift? The use of helium always seems so wasteful at this scale.
- ikrenji 4y agoi guess its not easy to build a container like that. it has to be strong enough to withstand the air pressure trying to buckle it in, but light enough for the vacuum to actually lift it off the ground. maybe there is no such material
