    Pretty clever if you ask me! Wonder if it would work on cars?

    Now if only they can bring the price down....



    Hmmm, theoretically there is no reason that this couldn't work for cars however in practice
    it is likely to be extremely hard to make that kind of wheel design withstand the punishment
    it would receive pounding down a motorway at 70+ miles an hour with several tons of vehicle
    on top.

    Also the reduced contact area is likely to significantly effect braking and cornering performance.

    There are also other options for cars to achieve the same level of mobility that still use ordinary
    wheels that are less practical on a wheelchair.

    As one of the comments on the article noted, it seems like it would be much simpler to use Mecanum wheels (http://en.wikipedia.org/wiki/Mecanum_wheel). They don't work great for difficult terrain, although the design in the article doesn't seem to be much better in that area.

    I need to copy this to my next door neighbour! The dents on my car are getting too much for me to endure.

    It says the navy bought the patent, wonder how much he got for it?
