 So sure, your Hyundai Sonata is built well. We're going to take advantage of the other residual power sources that are on this car because anybody who knows the internal combustion engine will tell you that when you burn gas, only a percentage of the total potential energy of that gas being burned actually moves the car, which is what it's supposed to do. You lose a lot of the energy, heat being the main part. So when that happens, you're just out. You paid for energy you didn't get.
