Bio-Inspired Propulsion

From the vibrations of the rear-view mirror just as a car reaches 70 miles per hour to a building that collapses when, in an earthquake, it begins to vibrate at a specific frequency, there is untapped energy that could be harnessed for propulsion. Researchers found relationships between frequencies and the passive dynamics at play when vehicles move in air or water that help them understand how to use these forces to enhance performance.
