The only thing lighter than hydrogen is... a vacuum airship. That's right, you can evacuate all of the air inside your aircraft to make it even more buoyant, but the problem is that the outside atmosphere will be pushing in with 14.7 psi so you will need a very strong air-frame to resist that force. Very strong air-frames are also very heavy... But! The ...

If you're willing to get a little weird with your physics, nobody I know of has ever proved that negative mass isn't possible. I.e. matter that is gravitationally repelled by positive-mass matter and attracted to other negative-mass matter like a magnet. We've never found any (and how would we? Any that was still left in the Milky Way when it formed would ...

I thought of plasma. Not a gas, strictly speaking and, when researched on it, it happens to be discarded in the WP article about this topic. You would need an elastic material that resists the huge inside charge (avoiding ions to get electrons or electrons being got) just to get a slightly higher lift. Plasma Another medium that in theory could be ...

This sounds similar to the Affront in Ian Banks' Excession. They are described as being: A bulbous mass about two metres in diameter, which hangs from a frilled gas sac one to five metres in diameter. Six to eleven tentacles of varying length and thickness grow from the central mass, of which at least four end in leaf shaped paddles. However they cannot ...

Assuming you have access to room-temperature superconductors, you can make a vacuum air bubble by wrapping a lightweight sphere in the superconducting wire and running current through it. The magnetic field built up can provide the structural integrity and prevent the vacuum vessel from collapsing or buckling (if one part of the sphere starts to buckle ...

Early aircraft were build out of wood, canvas and wire, and this construction extended to flying boats as well. Some flying boats simply used pontoons strapped to the airplane where landing gear went, while more advanced ones used hydrodynamic hulls. Felixstowe F2. 1917 So even using WWI era technology, you still can build capable flying boats. The larger ...

A geodesic sphere would be one of the best structural shapes. Depending on the strength of the materials used and the size of the airship required, internal struts could then be run from any node through the centre of the sphere to a corresponding diametrically opposite node. Graphene would be a good choice of material. Made into tubular form for the struts ...

A single envelope is inherently dangerous. One single pop and everyone is sky diving - minus the parachute. Even the great airships of yester year worked around this by not having a single compartment filled with hydrogen/helium, but by having many smaller bladders organised for easy maintenance and attached to the airframe. The outer skin was for aero ...
