THE COPPENHAGEN WHEEL – Students at MIT are about to change the world of transportation (and start a new business) with their new invention called The Copenhagen Wheel.  This is a great example of thinking outside the box! They developed a hybrid-electric wheel that can bolt onto any bike to help push the cyclist along. It also works with an iPhone to provide all kinds of useful fitness and location information to the user.
