Audi’s active suspension draws power from bumps in the road


Audi has developed an active suspension system – eROT – that captures kinetic energy from bumps in the road and potholes and converts it into electricity. From Engadget’s article:

To convert kinetic to electrical energy, the shocks use a lever arm that captures up-and-down wheel motion and transmits it to a 48 volt alternator. It’s then converted into electricity, with an average recuperation output of 100 to 150 watts — as little as 3 watts on a freeway, and up to 613 watts on a rough county road.
