The sport of motor racing is an important area of technology. The pace at which things change every year coming up with new ideas and thinking out the box just amazes me. To be able to have a battery that lasts 20 laps is big and i am sure with other developments this will improve by harnessing energy through other areas like braking. These are exciting times moving away from fuel engines and I can't wait to see what we will have in 5 years from now.
