Within a few days, he'd designed this safety pod, using the spiral-welded steel he uses for his houseboats. It has crumple zones to absorb impacts; racing-style seats and five-point safety harnesses for four passengers; a flashing beacon to alert rescuers; and hooks for helicopters to grab and lift it to safety. It even has one-inch-thick polycarbonate windows so you don't feel claustrophobic.
He said the pods will retail for $8,500 in Australian dollars, or about $8,872 USD, and they can fit in an average garage. A tsunami usually comes with at least some warning, so someone could conceivably wheel it out and hop in before the water rises.
