Bonaverde's “Roast-Grind-Brew Coffee Machine” seemed like one of the cooler inventions I've recently stumbled upon. But then I came across this: The Copenhagen Wheel. Originally created by researchers at MIT, the Copenhagen Wheel "transforms ordinary bicycles quickly into hybrid e-bikes." It allows bike riders to "capture the energy dissipated while cycling and braking and save it for when you need a bit of a boost" -- like climbing a hill in San Francisco. The wheel also feeds data to your iPhone, allowing you to monitor pollution levels, traffic congestion, and road conditions in real-time. After spending several years in development, the wheel can now be pre-ordered online and it will ship next spring. It retails for $699.
