>The only disadvantage really is that you lose most of the benefits of zero-G. for example, long running experiments requiring zero G. You also start to need walkways and paths. The ceiling of rooms becomes dead unusable space. etc. Docking new spacecraft requires stopping the spinning, which takes many days. For a one way trip to "elsewhere" none of that matters much. We'll probably see this approach investigated more fully when a one way trip to elsewhere seems more likely.
