mmh, interesting, but maybe Musk should see further to a way to travel (uncomfortably) for leisure. The idea can be designed with more important objectives in mind.<p>Maybe like a sort of eyectable-seat ships for people working in (and living around) nuclear power plants, or small islands under the influence of an active vulcano, or a way to evacuate almost inmediately in case of a missile attack. You can be more prone to forgive some discomfort or even pain if the other alternative is worse.
