Dawned on me after seeing this , our car batteries will be able to get fully charged from dead in about 20 seconds or so with this device:

A least thats the implication. That young lady is going to be worth billions as long as she protects herself with patents. Whoever buys her invention, I also bet their stock will go thru the roof!

At first, when I read your post, I thought you were taken in by some "con" job (e.g., this chip will add 20 hp to your n.a. B23 engine), but when I saw that she won the Intel International Science and Engineering Fair, I'd say that this was adequate scientific "peer review" substantiation to prove that it's real.
However, don't get your hopes up for a quick real-world application such as your car's batteries. There's a big scale-up problem with anything like that, especially using nanotechnology -- i.e., there's a world of difference between lighting a single LED and commercial manufacture of automobile storage batteries.
And I would expect that there would be a much larger incentive to apply any such scale-up to the "traction battery" application in electric cars which still have a big hurdle (i.e., no one wants to charge their car for a long period to continue their trip, preferring only a few minutes as we currently do with a gasoline refill; and also the limited range of such batteries), compared to a gas engine's battery which, frankly, has little problems (or any incentive to improve their technology -- i.e., they're mainly good enough). After all, how many times do you ever have to charge your car battery -- if you do, it's usually a sign that you either have something wrong with the car, or you need a new battery.
In any case, I'll bet the technology, if it ever scales-up from single LED capacity (pardon the pun), will be used to power phones and other small portable devices many, many years before it powers electric cars.

I suspect, even if this technology makes it to cellphone battery size, physical limitations will mean that it lasts for a fraction of the time of a normal battery. I would put money on the prediction that the technology will never be used to start a car.

According to what i read, a cell phone gets a full charge from her invention in about 20 seconds and lasts as long as a "normal" charge. Thats the selling point. Got something to do with her invention "storing" and releasing the energy very fast and keeping the size of her invention way down .
I really dont "get it" but try reading other web sights about it. In some ways it makes perfect sense, even if the technical aspects are past my understanding. If that invention only gave a usuable short time of charge in those 20 seconds, then why would anyone want it? Its something to do with the volume being cut down in size, I think, but still giving full energy to a batterys full capacity. I think it will be interesting to see just what comes of this.

Sorry, but you weren't clear about the "time" in your statement, "lasts for a fraction of the time". For example, these are some possibilities:
1) the time to deplete the battery at a given rate of discharge (i.e., reflected in the measure called amp-hours).
2) the lifespan of the battery (i.e., how long before the battery is worn out and must be replaced).
Regarding (1), the recording clearly showed that the battery had a higher energy density of electrical storage (what could be called amp-hours) -- likely, on a weight basis, although it could also be volume.
Regarding (2), the recording was extremely clear that it can provide about 10x the number of discharge-charge cycles as ordinary batteries.
Also, what "physical limitations" are there that causes the reduction of the "time" element, to which you were referring? For example, I don't believe that this battery would have to be bigger (a physical limitation?) to provide the same or more energy than a wet-cell battery (again, consider the claim of energy density). In fact, wet-cells are notoriously inefficient in terms of energy storage per volume as well as per weight.
Nevertheless, I am also skeptical, as you are, of its future as a car battery, for me because of the difficulties of scaling up nano-technology: what can be created in a lab in a petri dish doesn't always easily translate to commercial-scale mass production (especially at sizes and numbers applicable to the auto industry). She was holding a battery about the size of a small product label or file tab, which was large enough to light a LED; a car would need a battery (for a conventional, gas engined car) about (very roughly) 10^6 times as large. Now try that enlargement without inherent flaws or defects in the nano structure, the continuity of the conduction pathways, etc.

Many are skeptical about most any 'new invention' such as I was when a friend told me long ago that computer 'chips' were being made out of sand.. silicone.. and would be so small--yeah right! He mentioned the word 'Apple'...if only I took it serious......and bought some stock at that time.
As one said here, this young lady recieved a $50,000 award and is headed for Harvard. I think she's got something there. Might be interesting to see where this is headed. I'm sure there will be 'scoffers' and can't say as I blame them. I'm going to try to keep an open mind.
I do hope she already has patents in the works, including international patents . She would be smart to have applied for patents before this was announced publicly.
The concept may be past most of our understanding, but i think I get the basic premise. I think... ? :o/
We will see.

I'm not "scoffing" her idea, just skeptical that it will be practical any time soon -- the notion of nanotechnology is the sticking point.
Intel may already have some patent rights, as it is the "Intel International Science and Engineering Fair" (formerly, many decades ago when I went to
Bx. Science, known as the National Science Fair) until Intel "privatized" it.
And if she continues her research into this technology at Harvard, Harvard will certainly have some degree of patent rights to that invention -- as my daughter, a double Harvard grad (A.B. and J.D.), once pointed out to me that any inventions using Harvard resources (a very broad definition) bestows at least some(!) rights to Harvard -- and they know how to greedily protect their rights, to say the least!
And oh yes, $50,000 -- aah, that should cover a little less than one year's tuition bill+miscel. costs at Harvard (aside from financial aid, depending on her parents' figures). But it will be worth it!

Another supercapcitor application.
A most promising technology.
For car batteries, doubtful.
Yet more useful for electric cars when these do scale up.
Well, we'll see.
Well, we can see now here at (http://green.autoblog.com/2011/07/18/video-green-overdrive-solar-charged-electric-volvo-240/).
Dudes, its even cooler in that it is a 242.
I believe the Volvo 240 would exceed any modern era crash test save for the lack of WHIPS, SIPS, and such that only Volvo made and has licensed to all the other global dumb car manufacturers.
cheers,
Dud MacDuffed.

Supercapcitors in Volvo 242s, onward! Now if we had a Volvo 243 coupe with hatch back a la' P1800 and a Volvo 162 coupe with B30 and M410. Solid.
How many times did I say Volvo today?

Uncle pageda,
Indeed and truly, your comment.
I'm still so ANGRY at the cash for klunkers crap. These videos on YouBoobToob show people killing Volvo engines so they can show how they have failed and turn in the once thriving Volvo as a klunker for cash.
There is one showing a 960 or S90 and they dump some crap into the oil fill cap hole and they race the engine and the engine smokes and seizes. I got so angry and about cried for the poor thing. Even a 960/S90/V90 deserves care and love, yes? They are very nice cars but boy oh boy those timing components and a valve train that about equals the 1934, New York Central Hudson #5344 train that was was fitted with a sheet metal shroud and became the first streamlined locomotive in America, dubbed the Commodore Vanderbilt train.
So many RWD Volvos, Saabs, and BMWs and other worthy to care for imports died in that fiction of welfare for those so unworthy.
Yeah, indeed. I'll hold my massive and endless contempt for so many that do so much damage out of a grab from greed for power.
Where does one go? Sweden? Denmark? Germany? What just and honest nations exist anymore? Canada and the heavy tax and expense you to death?
No matter your religion, they all agree that "usury is a sin." This is one nation under the {secular} god? How about that debt?
Welp, gotta go so some inner tie rod action. Uncle otherdalek and I are virtually dancing Volvo the inner tie rod replacement action. His is a 740. Mine is that grey 1991 240 I go on and on about.
Mighty is the Volvo 240.
Hope all's aces.
I apologize again for my posts that revealed my cantankerous and condescending side on the brickboard.
cheers,
Stilton Cheese Boy
