And who is going to find all those capsuled people and rescue them? Rescuers will be swamped with hundreds of thousands of non-capsuled people who should logically take priority. Depending on how these things float, if they get swept out to sea, you might need a ship with a crane to lift the capsule aboard. Does it float nicely with the hatch open or do you have to stay sealed up to stay afloat? Can you float with air ports open or do all of you have to stay breathing that scuba tank in the photo; how long will that last? What will many -- thousands? -- of EPIRBs all going off at once do to the SAR system?
