Airless Tires

Did anyone see the new airless tires in the lastest Popular Science magazine?  I read that they are not going to be available for automotive applications until ten years from now because they are so noisy.  They are supposedly made from a composite of sorts.  I do not have the article with me, but I was wondering if anyone knows any more about these tires, or could point me to a website with more details.

NASA Tech Briefs just had a short piece on them.  The spokes are a deformable polyurethane.
