An emergency portable device to save a person from a rushing tsunami-?
I’ve seen the aerial video from Japan where cars are driving away from the coming tsunami yet another wave is heading in front of them. All those people who got swept away even with ample warning…I can’t help wondering whether there could be a minimally maneuverable portable device for a single person that he or she could deploy in one minute or less to lift his body up like a balloon in order to escape the water and stay afloat until rescue arrives-?
