Re: Space Island Group

If you're going to bother inflating something, just use one of Bigelow's
inflatable habitats and forget the tank - this technology has already been
proven to be quite impact-resistant.

Agreed.

Using spent fuel tanks sounds good, but once you start looking at the
details, it isn't clear that it buys you anything. Skylab looked at
using spent fuel tanks but eventually decided against it.
