An anonymous reader writes "Japanese company Air Danshin Systems Inc. has developed an innovative system that levitates houses in the in the event of an earthquake to protect them from structural damage. When an earthquake hits, a sensor responds within one second by activating a compressor, which forces an incredible amount of air under the home, pushing the structure up and apart from its foundation. The air pressure can keep the home levitating up to 3cm from the shaking foundation below. In the wake of last year's Fukushima disaster the company is set to install the levitation system in 88 houses across Japan."
