Walking

Walking is controlled falling. We shift our balance from side to side and the body responds using complex muscle control, sophisticated kinetic feedback and real time recursion to make it happen. Scientists are now starting to develop tech able to harvest energy from non linear motion sources like walking, wind and tidal currents. Pretty cool approach to the energy crisis to say the least.

"The range of applications for non-linear energy harvesters varies widely. For example, Mann is working on a project that would use the motion of ocean waves to power an array of sensors that would be carried inside ocean buoys.

"These non-linear systems are self-sustaining, so they are ideal for any electrical device that needs batteries and is in a location that is difficult to access," Mann said.

For example, the motion of walking could provide enough electricity to power an implanted device, such as a pacemaker or cardiac defibrillator. On a larger scale, sensors in the environment or spacecraft could be powered by the everyday natural vibrations around them, Mann said."
