A crash course in changing the world.
I have to design a new way to power something to use everyday. Everyday, I use my car. When i go somewhere, most of the time I use my car. Recently, I have heard that to drive a car, it requires a battery. The battery is use for lights in front or the car, lamps inside the car and for charging phones or the cigar jack. It depends on much the user are using but normally it last for a year or two. It cost about $50~$120. From this, i have got an idea to safe the money and make it sustainable. To run a car, it uses energy from the fuel and makes the motor move. So my idea is when the engine moves and the wheels are rolling, from the rolling wheels it generates the energy by itself and makes the electricity. It is similar to wind power generator's principles. Install the generator on the wheel so that when the wheels move, it will make the energy.
