For all practical purposes 100Pa is space like vacuum. The forces on the vacuum chamber are still immense, the consequences of failure still catastrophic, and breathing still impossible. The only difference is that the turbomolecular pump based engine is not theoretically impossible.

Pressure in outer space is more like 1E-11 Pa, at the Kármán line 100km above sea level we still have only 1 Pa. > The forces on the vacuum chamber are still immense, 100 kg/m*m isn't immense in my book. > The only difference is that the turbomolecular pump based engine is not theoretically impossible. No one is talking turbomolecular pump here, these are used below 10mPa. For 100 Pa an ordinary displacement pump will do.
- jessaustin 10y ago100 kg/m m isn't immense in my book. Yeah, ISTM most floors in commercial buildings that serve crowds could probably handle that. (Not to say that such floors are airtight, but the basic engineering of supporting an average American man on every square yard of a particular surface is quite feasible.) It would be even easier for a self-reinforcing structure like a tube.
