In our quest to find cool things made for the future, we found these this week:

1) Are you sick of flat tires?  Say hello to “The Tweel!” Half wheel, half tire, this Michelin brainchild has no air so it can't go flat.  But is it safe? Well, the military likes it because it stands up to gunfire, shell fragments and even land mines better than normal tires.  The only hitch is it vibrates when you drive over 50 mph, so you may want to put Tweels on our car before you lend it to your teens.

2) One of our favorite websites is Kickstarter.com, where inventors raise money to turn their ideas into reality.   This concept is a good one.  Form Labs has developed a 3D printer that combines high resolution and low cost. It creates complex geometric prototypes for architects, designers, and engineers.

3) It's one thing to recycle your cardboard, it's another to recycle it and turn it into a bicycle. Izhar Gafni, an Israeli engineer, developed a technique to fold, glue, and treat the cardboard so the bike would be both rigid and waterproof.  And it cost him $15! 

Now if only he could only make some cardboard Tweels.
