I am supposed to design an energy storage system for a car, so I want to calculate how much energy can be stored in a capacitor whose geometry matches the car. As a baseline, we have an area 150 cm wide by 2500 cm long by 30 cm tall. The capacitor is a sandwich geometry , one layer of conductor, one layer of insulator, one layer of conductor etc. There are n+1 sheets of conductor and n sheets of insulator. The thickness of the insulating sheets is equal to the thickness of the conucting sheets, d. Paper is the insulating material. It has a minimum thickness d, 50 micrometers which is twice the thickness of paper. The conducting sheets alternate in voltage between +V and -V. I am trying to figure out how much energy can be stored in this capacitor if a factor of 2 for the electrical breakdown of the insulating sheets and adjusting the thickness d to maximize the energy stored. I also need to find the maximum voltage. I am not even sure where to start. Please help!
