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."
HEY!
I want my friggin 15 hour battery life laptop first! You promised!
Perhaps they can use this technology to make more lethal tasers. Or at least tasers that give some good burns.

Yes, but are they as incendiary as a SONY battery of the same size?
The theory of relativity doesn't work right in Arkansas.
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.
APK quotes people (including myself) without context and should not be trusted. Just thought you should know.
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.

...you read that title as "Utahraptors soon to replace many batteries"
What sound do people on rollercoasters make? Hint: it's not Xbox 360.
Does being on slashdot mean that you must be rude?
:)
You must be new here... idiot.
Random and weird software I've written.
No, thank you.
Half right. Yes crashing would deplete the capacitors but it would also recharge the capacitors of the car your hitting.
:D
The solution if you run out of energy? Just wait for someone to hit you.

"Just every time you charge it, you induce more entropy in the universe."
Is it wrong that this seems vaguely threatening to me? While I know everything we do either has no effect or introduces more entropy into the universe, something about "every time you charge your phone you bring the entire universe closer to its death" is just a turn-off.
Also, this is suddenly my favorite vague defamation statement... "X lives an entropy-positive lifestyle, and every day brings us closer to the end of the entire universe!"
Unfortunately EEStor's prototypes are currently made of unobtanium plated vapor, but that's a different matter...
Stop this tomfoolery at once.
