Two interesting things. The first is this cardboard bike
The Alfa weighs 20lbs, yet supports riders up to 24 times its weight. It’s mostly cardboard and 100% recycled materials, yet uses a belt-driven pedal system that makes it maintenance free. And, maybe best of all, it’s project designed to be manufactured at about $9 to $12 per unit (and just $5 for a kids version), making it not only one of the most sustainable bikes you could imagine, but amongst the cheapest, depending on the markup.
The second is this wind driven de-mining device for use in Afghanistan with the video below the fold.
I understand that the de-mining device might not be the total solution (I wouldn't be walking behind one of them into a minefield), but, the sight of these 'mine kamon' propelled by the wind across the desert at the end of the video makes me smile. Anything that gets you to do a Duchenne smile?
