Design an ultra-capacitor. Find an electrode geometry which maximizes the stored charge for a 100 cm3 volume. Discuss possible physical limits for the design, including dielectric breakdown, leakage current, and mechanical stability. Assume the operating voltage is 16 V. Compare your design to performance of commercially available units (e.g.from Maxwell Technologies).
