"Building one space station for everyone was and is insane: we should have built a dozen."
- Larry Niven

Membrane Balloon Helmet  
  A selectively permeable membrane worn as a helmet.  

When Hanville Svetz, time traveler from our future, tried the air in 12th century Britain, it was a bit rich for him.

When next he left the extension cage, carrying the flight stick, Svetz was wearing another spin-off from the interstellar-exploration industries. It was a balloon, and he wore it over his head. It was also a selectively permeable membrane, intended to pass certain gasses in and others out, to make a breathing-air mixture inside. It was nearly invisible except at the rim. There, where light was refracted most severely, the balloon showed as a narrow golden circle enclosing Svetz's head. The effect was not unlike a halo as shown in medieval paintings. But Svetz didn't know about medieval paintings.
