Cool videos: human powered walking vehicles

The video meant to be presented here is no longer available. Sorry for the inconvenience.

I know what you're thinking: "Walking vehicles? It's better to just walk." Sure, transferring power from your feet to a mechanical set of legs may be needlessly repetitious and simply waste energy in the process. Human-powered walking vehicles (like the working model in the video above and a concept in a clip below the fold) solves a great problem. Walking vehicles and walking assist robots all have one major problem: they use energy. Why not walk by using the power of your feet instead with these amazing machines? Okay, sure a bike is more efficient but you gotta give 'em an A for effort.
