"From an energy perspective, your car is really just a heat machine that happens to move. Only 10 to 16% of the fuel energy that you burn moves the car forward (by overcoming air drag and road resistance), while the rest is dissipated on its way to the drive train. But engineers have been looking to get more bang for their burn since cars rolled off the assembly line. One overlooked source of power has been the suspension system—until now. Conventional shock absorbers dissipate energy through a combination of coiled metal springs and hydraulic dampers. Several engineering teams are now developing what is essentially a miniature power generator for wheels that will convert vibrations into useful energy, as well as a smooth ride."

This question will come off a bit ICP-ish. Could all of the force of cars driving on highways be captured as energy - by some kind of membrane? How about really heavy, stationary objects, like houses? Can you capture that gravitational force and use that as energy?
I haven’t taken a science course since high school, and I’ve never goofed off more than during physics - be gentle.
