"Buildings sway ever so slightly in the wind, bridges oscillate when we drive on them and car suspensions absorb bumps in the road," said Ryan Harne, director of the Laboratory of Sound and Vibration Research. "In fact, there's a massive amount of kinetic energy associated with those motions that is otherwise lost. We want to recover and recycle some of that energy."

At first, the recovered energy will be used to power the sensors that keep tabs on the structural integrity of buildings and bridges. In other words, the system will be self-sufficient, able to power itself from the vibrations created by moving the wind or from cars driving across it. Harne says the tree-like structures could eventually be used in small-scale scenarios where other alternative energy sources, like solar panels, aren't an option.
