The Tsuanmi Ball is a design creation put together by Chris Robinson in light of the Japanese tsunamis that occurred as a flood survival tactic. The pod is essentially a floating capsule that can stand drifting off in flooded conditions as well as a slew of damaging weather hazards that follow suit.
The design is essentially a rounded ball-like cabin that is made using wood panels and a curved design that can withstand pressure being applied from all sorts of angles. The space measures 22-feet and offers a safe emergency hide out space in case of water damage. To help others, Robinson has also put the designs for the pod online so that others can follow his instruction and build their own.
