Nice video Derek,

Happy to see that more lowtech solution are being develloped.

I have seen the same concept but with high cost materials such as Shape Memory Alloy

I wonder about combination of sismic and hurricane..the house can fly away...

I was intrigued with the 10 minute video linked below, which describes building a house connected to the foundation only by gravity.  The house sits on a number of plastic pads, each about 100mm in diameter.  Each pad sits in a shallow dish 750mm in diameter.  The idea is that the ground can shake and move under the house, while the house itself will move to a smaller extent, with lower acceleration.  The dished support plates encourage the house to re-settle near the center of the dishes.  Professors and students from several universities are shown in the video.  They claim “damage-free” in a 6.9-magnitude earthquake, simulated on a full-scale shake table test.
