"Modern science fiction is the only form of literature that consistently considers the nature of the changes that face us, the possible consequences, and the possible solutions."
- Isaac Asimov

| 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. |
