    That is a great idea, another is this: the NORAD installation is isolated by custom-made springs that are capped on top and bottom ends. Any ground movement is not noticeable. Interesting.

    I think all of the comments so far are pretty reasonable concerns.

    I live in SoCal and in 1994 Northridge quake (mag. 6.9) the electricity went out immediately – the transformers have seismic safety switches. My 4 year old saw the blue flashes of the transformers shutting off and thought they were magic stars.

    All houses here are required to be bolted to the foundation. Poorly bolted homes literally slid off of their foundations during an earthquake. Now the levitating house is as slippery as a puck on an air-hockey table. All seismic isolators will also require a dampening system to hold the house in place.

    Also, many earthquakes bounce up and down. Areas of Northridge recorded vertical accelerations as much as 1g. (the force of gravity). In other words, enough force to throw the house upwards. Be cause the house is detached from the foundation, what prevents the vertical motion of the footing from whacking the house apart?

    I’d like to see how well the house does on a shake-table with a motion that more accurately resembles an earthquake before I move in.

    My concern is more the myoptic sort… what about other disasters now that the house is not firmly attached to a foundation, high wind, flood, etc?

    How many houses can actually load the floor systems to raise the structure without causing other extensive damage? Interesting technical challenges regarding utilities (electical, gas, water, sewer). What if the house just crumbles from the loading?

    If you get a significant horizontal displacement (six inches is common) will you be able to set the house back down safely? will the skirts or whatever aligns it just x-fer loads to the house anyway?

    Yeah, it would be nice to see some more technical exposure here.

    There is an air tank in the diagram, and a big enough valve can fill it quickly as the structure can handle.

    A small battery backup would be more than sufficient to open a valve and fill the airbag.

    Hovercraft have skirts, not airbags.

    Stop hating.

    What’s to stop the house floating off its foundation like a hovercraft?

    @nigelhay: I’m thinking that the compressor and air look one will fare just fine. The compressor is likely rubber-mounted, although they tend to be rugged enough that this would be overkill anyway. And what kind of damage do you expect to see done to a flexible high-pressure line?

    What if the electricity is out, like in many cases during an earthquake. Do they have a emergency generator? how reliable?
    I still think that good design is the only earthquake proof technology.

    Sort of like an airbag for a house instead of a car? Agree with the concern of getting air quickly enough through the pump. Earthquakes last seconds, so response time for the compressor will need to be fast. I wonder if the car airbag technology of using a chemical reaction to produce nitrogen gas would work better/faster than trying to pump in the air.

    How does the compressor pump enough air that quickly? What’s the advantage over a flexible foundation? And so on. The article doesn’t provide any technical details. `~- Nehmo

    So what happens to the compressor when the earth quake hits. Does it levitate as well.. Not possible i think.. and the air line to the levitating mechanism can also be dammaged.. i think this has holes in it.. :(
