make bigger batteries, bigger chargers, and even bigger outlets

Is it just me or does this article seem quite unfinished. Maybe have some suggestions on how this is relevent?
My blackberry charges in about an hour and lasts 2 days with moderate use.
Is it reasonable to assume a charger can be built to plug into an electric drier outlet (220v 30 amp) and charge my phone in 30 minutes?
How did they handle excessive heat charging a battery that fast?

Please finish your article, this is very interesting to me.

This looks like it can continue for several more paragraphs, but interesting article. It would be an interesting asset to have, but what about heat problems (at the least)?

The point about the thermal problems with these batteries has been addressed with the development of a new barrier by Exxon/Mobil which has greatly increased flow-through and increased thermal breakdown temperature. Google it for info.

Thanks for the precision Kevin, I went to many different websites and nowhere did I read that.

@ jdj1976: In my example it is 1 MJ, not mj. MJ = MegaJoule, whereas m is milli. The difference between both is only a factor of 10^9.

Also, the point of this new technique is not to have longer-lasting batteries but to recharge them quicker. What if you could only leave your Blackberry plugged 30 seconds instead of 1 hour? That would be great.

If it proves viable this fast charging battery would find it most dramatic use in electric powered autos. Fast recharge would certainly make electric autos more desirable. According to conversion method posted elsewhere on the web, 1 MJ is equal to roughly 1 oz. of gasoline. Lets assume that electric powered cars are twice as efficient at using energy than gasoline autos are. This assumption then leads to the result that 64 MJ of battery is equal to about 1 gal of gasoline. I'm guessing that we all use on the order of 2 gallons of gasoline per day. You can quickly extrapolate from the calculation posted by the author that the capacity of the power grid would have to dramatically increase in order to meet the power demand of a community of homes using battery powered cars.

Yeah, I was thinking about that myself. If batteries get that efficient, and everyone starts using them (unless they were prohibitively expensive, why not?), the higher level of efficiency means that little power gets returned to the grid when these things are charging.

Sure, charging AA type batteries won't cause any real problems, but if a lot of people end up with electric cars, and even companies start using them, this may become a bit of a problem.

Still though, this is pretty awesome. The main reason I don't use rechargeable batteries is because they take so long to recharge (I dislike the inconvenience I admit), but if they could recharge in less time than it takes to eat a meal, I'm suddenly very interested.

We'll have to see how prevalent these batteries become though.

Your PSP would likely be charged in seconds. It theoretically would top out at 1 second with the above example should there ever be a way to hit the maximum speed.

Isn't that why Doc Brown made the Flux Capacitor?

In the UK voltage is 240 and a standard socket will take 13 amps, hence we can charge stuff almost twice as fast
