Very cool stuff. Click here for the story link.

I sort of want one...because it's made of cardboard.

I want one too 2-ton. I bet it wouldn't cost much more the $30 to sell if mass produced; may even be much less then that. If this guy can ride it, then I know I could too. There truly would be no excuse to not own a bike then as well. Cool stuff. When I was much younger, and in College, I would swim for 1.5 hours one day, the next, I would walk 5 miles (around 1.5 hours), and the day after that I would ride my bike for 1.5 hours (according to the bicycle odometer, it was around 30 miles). Had to keep excercising since I was in the Army Reserves then. Hated running (which I should have been doing and would add that to my routine a month or two prior to a PT test; lol). Wish I had that motivation and dedication now; only walk around 12 miles a week now which pales to what I use to do (and my fat stomach's the proof of my petulance of an effort; lol).

That is so cool. Yep, it can change the world for sure.
