How many of us try to come to a sudden stop at a red light? “Damn I thought I could make it”is the common misconception. Now consider if we managed to tap into this breaking energy at signals into maybe to power the signal or feed to a grid or power the street light. Obviously it would not help for all signals and the next question I had was what about ABS and other anti breaking techniques complicating the process.
I believe all that is just a matter of bringing those variables into fixing the equation on what kind of a system do we employ to harness electricity from these stop and go drivers.
