I realize the the super capacitor industry is struggling. Of course it is. Anything with such industry changing potential is always struggling.
Everyone knows that capacitors can store electrical energy. Unfortunately, regular capacitors can't discharge that energy slowly, they discharge all of their energy in a single flash. Enter super capacitors. Unlike their cousins, super capacitors can not only store energy like their cousins but they can discharge their energy gradually, not all at once. Thus, they work like a batteries. Unlike a battery, however, super capacitors can be charged and recharged indefinitely, no battery life problem. In addition, super capacitors can be recharged in a matter of seconds rather than hours.
I'm so impressed with the range of the Model S. 300 miles is exceptional for an EV. With batteries, some still struggle even with the 300 miles because recharging the batteries for another 300 mile drive will take hours. This means long waits every 300 miles or you have to carry multiple battery packs which is cumbersome to swop. As a second downer, batteries have life spans. The older they get the less charge they hold until they're no longer viable.
It would seem to me, a little homework and brainstorming would make it possible for a super capacitor pack to replace the battery pack with no loss in performance. You could still get the 300 mile range. However, the recharge would only take seconds to achieve. Further, super capacitors do NOT degrade with use.
What would this mean for the EV? Suddenly, the EV can compete toe to toe with fueled vehicles. You can take them on long trips and only spend seconds to recharge and continue the journey. You no longer worry about battery life because super capacitors do not degrade. Now, finally the EV can replace the fueled dinosaur vehicle technology. Fuel independence becomes a reality. With all the massive work that has gone into the Model S and roadster, wouldn't this last breakthrough using super capacitors be worth the additional design and development effort?
Well, it's a thought. I'm so impressed with what Tesla has done so far. I can hardly wait to purchase one of their vehicles when they're available. We love Toyota Hybrids and drive they all the time. We're so glad Tesla has teamed up with Toyota. May their combined efforts be super winners. Thanks, The Phoenix
