this is really cool

old news. Thanks

A definite candidate Green Innovation award.. but then Apple will put a patent on it by adding "for mobile devices" to the end of that.

true that to the apple thing

Is it possible only for paper?

Very impressive! Now if they could just make some progress with room-temperature super-conductors, our overall state of technology would really leap ahead!

"Coming Soon"...

We always her about new developments like this, but nothing large scale ever comes of it.

Stanford's creation is efficient enough to retain a reasonable capacity after around 2,500 claimed recharge cycles.

Most applications that use normal capacitors charge and discharge (at least partially) the capacitor almost constantly. 2500 cycles would give this a lifespan of a minute if you are lucky. And I know cell phones are getting to be a commodity item with no long term use or value, I would still like more then a single call out of it. Or would it be like disposable cameras where you toss it once your minutes are used up.

Time needed for basic research to be translated into real world applications takes on average 10-20 years depending upon the field.

"Coming Soon"

Valid point, but sometimes miracles do happen...

I remember hearing some sci-fi predictions about tv's and monitors that you could hang on a wall like a picture frame, instead of the giant box that took up a quarter of my sitting room... amazing!

Does this mean we might see paper batteries?

Supercapacitors are not used like normal capacitors. Their series equivalent resistance is very high and their capacity is much greater than normal capacitors. These properties makes them more attune to use as short term batteries. As such, 2,500 cycles would make them useful.

I looked but I could not find if Tom´s made a report about paper circuits a few years ago (perhaps because it was portuguese technology, and so, news don´t get to Tom´s).

I can see things made with this easily catching fire. Don't overvolt (or overclock) or you'll burn out your CPU... literally! argh!

 

[nforce4max]

I still remember the very old paper caps that were in use before electrolytics became cheap enough for consumer electronics. They often simply rotten away over time. Lets hope the iThugs over at Apple don't hog this as plunder for them selves.

And that's why they don't put a release date on it. But I'm sure somewhere in the future these ideas may be used in combination of other things.

TOMS!!! There is a story idea for you, go back and find a couple of these articles from a few years ago that actually worked out and are in production today. I'd read it!

Most capacitors can handle millions of cycles without any significant degradation. 2,500 cycles is pathetic for a cap.

And no mention of its energy density etc. If it has very high energy density it might be worth something. But no data, so no way to know.
