Missing from the article is any details on ventilation. You need fresh air to survive, which means non-water tight holes will be somewhere on that thing. Normally on a boat, they would be on the part that's above water. On a spinning ball, that wouldn't be an option.

My best guess is that it will be integrated in the center tube. Buoyancy ensures the center of the ball is usually above water, and one end of the tube would always be above water.

You only need to get rid of CO2. There would be oxygen enough in the sphere for quite some time.

		Yes, so now you're talking CO2 scrubbers, air monitoring, O2 replacement, cabin pressure management, and reliable power to keep all this life support running. It's basically a submarine at that point, all for $20k per pod? I'm skeptical this is practical.

Also missing from the article is the fact that the maker hasn’t shipped any capsules yet… their site says you can pre-order one!
