Ultracapacitors Soon to Replace Many Batteries?

einhverfr writes "According to an article in the IEEE Spectrun, the synergy between batteries and capacitors — two of the sturdiest and oldest components of electrical engineering — has been growing, to the point where ultracapacitors may soon be almost as indispensable to portable electricity as batteries are now. Some researchers expect to soon create capacitors capable of storing 50% as much energy as a lithium ion battery of the same size. Such capacitors could revolutionize many areas possibly from mobile computing (no worries about battery memory), electricity-powered vehicles, and more."

    Could someone explain this all to me please?

    Are Ultra capacitors like flux Capacitors that you can use to go through time once you're travelling at 88mph? If so I don't think this will be very efficient at all since they require 1.42 Gigawatts!

    Thank you. You just gave me a new sig.

    Yeah, that's a good point. Because I'm sure the blueprints as drawn call for the capacitor to be stored as bare metal plates, with maybe some saran wrap protecting them.

    No, thank you.

    Half right. Yes crashing would deplete the capacitors but it would also recharge the capacitors of the car your hitting.

    The solution if you run out of energy? Just wait for someone to hit you. :D
