Rolling Resistance
What's the potential rolling resistance of this sucker when executed well on bi-cycle:

that's pretty cool, if you ask me - why? cuz it seems to be demonstrating concepts that strike at the core of reducing "rolling resistance" in an outside the box approach.
Then again, y'all must remember that I think decoding SRM binary power meter files is prety cool too, so yeah, YMMV!

That IS cool...it looks like a semi-practical implementation of the "radial springs" idea described in Whitt and Wilson. Also, reminds me a little of the wire mesh "tires" used on the lunar rover.
Hmmm...thinking about the practicality for a 2 wheeled vehicle like a bicycle, I'm wondering if it's possible to get the same amount of lateral stability like they can with a car tire. The width/diameter ratio is a LOT different between those 2 cases.
Besides, the requirements for a car tire vs. a bicycle tire can have some significant differences...there's a reason that radial tire construction has never "taken off" in the bicycle world.
Cool link though...if they work on getting that last bit of rolling resistance improvement needed to match a pneumatic tire, they might have a "winner"...hmmm, I wonder if they would come up with some kind of replaceable road interface (i.e. tread) so that you wouldn't have to replace the WHOLE thing when it wears out. I would think that could be a BIT expensive.
