What if you could use carbon fiber as a battery? That's the idea scientists at the Imperial College of London are working on, aiming to build a car out of carbon fiber material that would not only function as a battery, but will be a strong and light substitute for the sheet metal on cars today.
Not only will it save weight and volume in a car, it would eliminate the need for wiring, letting engineers route electricity through the car's carbon fiber structure. The technology could be taken way beyond cars, also built into airplanes, cellphones, or anything that uses batteries. Just imagine a cellphone as thin as a credit card. Brilliant.
