What is Digg?53 Comments
- breadfred, on 09/20/2008, -3/+42Wow... 15 minutes to fill up your tank? What do you drive, a hummer with external booster rockets or something like that?
- thenativeraver, on 09/19/2008, -0/+30I've always thought capacitors should play a larger role in storing electricity.
Dugg! - Carnage6669, on 09/19/2008, -2/+30Now we are getting somewhere. I have long awaited the increase in plausibility of this tech to enter the automotive industry. Not only for obvious reasons, but it may lead to a material that has a greater energy density than Petroleum, there-by paving the way for Electric cars that have greater range and "recharge" faster than a Petroleum Engine. Think about recharging your car in 15 min like you do at a gas station.

carbon nanotubes are going to be to us in the future like plastics became in the late 20th century and now - incredible and their use widespread - LucasVB, on 09/20/2008, -0/+13I love this technology. I've been following supercapacitors for a while and they're pretty much the perfect batteries, given that we reach a reliable energy density. It's cool to know we're getting there!
- gritta, on 09/20/2008, -3/+15I have invented an amazing Digg article name predictor! Pick one from each row:
1. Incredible New // Revolutionary Green // Tomorrow's
2. Super Battery // Gasoline Replacement // Energy Source
3. Discovered By // Tested By // Reinvented By
4. Japanese Car Manufacturer // 12 Year Old Chinese Boy // Fifth Grader's Science Project - K4P741NxKRUNCH, on 09/20/2008, -1/+11I been tellin em for years, electricity is not a dump truck, it's a series of nanotubes!
- KampfGherkin, on 09/20/2008, -1/+11Meh, I'm tempted to bury this for being real cheap on any actual specifics. It's basically advertising an article in a publication, so this is borderline spam I reckon. No technical details or even a mention of actual/potential power densities. Boo!
- Jakerzon, on 09/20/2008, -0/+9My other question is: What happens when a supercapacitor is destroyed? What happens to all that stored energy?
- wafflesomd, on 09/20/2008, -0/+8So, what amount of charge can these hold, and for how long?
I assume most people are interested in those questions. - drcosquared, on 09/20/2008, -1/+9And yours sir, is paid for by the National Organization Against Cool Things(NOACT)
- mebethekoko, on 09/20/2008, -0/+6The article you linked to is about a silicone nanowire lithium battery. Has nothing to do with either carbon nanowires, nor supercapacitors.
- Bith8654, on 09/20/2008, -0/+6Waiting 15min minutes at the gas station > Waiting 5min and paying $50-100 to refill my tank.
- RabeiUsura, on 09/20/2008, -0/+5I'll digg this when they reach commercial uses.
- LucasVB, on 09/20/2008, -0/+4I wish :(
- trogdor282, on 09/20/2008, -0/+4But how am I going to haul this load of gravel???
- ajb2015, on 09/20/2008, -0/+4enliven radios? please put away the thesaurus.
- OuijaCat, on 09/20/2008, -0/+315 minutes at the gas station? That must include time spent at the slurpee machine, picking up beef -jerky, newspaper, cigarettes & lottery tickets.
- charlietuna, on 09/20/2008, -3/+6Techies are always pushing the technology over the results. The point is not *how* a good energy storage device is made, the point is that it works well and in a safe cost effective manner. As it stands this is a nifty FYI article. For all we know it's still less effective than electrochemical or hydride based methods of energy storage. Cautiously dugg up.
- brianpeiris, on 09/20/2008, -0/+3Dammit Science, Hurry up! Chevy insists that their Volt will take 2 years to build, cost about 40,000 and that's the ONLY viable choice we have right now.
I would donate a bit from my own wallet if it meant these guys could get the research done at more than a snail's pace. We need to fund this stuff pronto! - inactive, on 09/21/2008, -0/+3No, he's just factoring in waiting on the wife.
- coreyb, on 09/20/2008, -0/+3Yeah, too many questions left after reading. The article was a little slim on actual info...
- l800LEMMINGS, on 09/20/2008, -0/+3when they were first experimenting with ultra capacitors in the automotive industry some of the first test results were showing a charge that would let the vehicle travel 500 miles in a 5 minute charge, that was years ago, i wonder what advancements they have made since then
- riggs32, on 09/20/2008, -1/+4i hope this technology comes soon, my laptop battery only lasts about 3-3.5 hours. its 2008 ppl, about time we see a revolution in batteries!
- localzuk, on 09/20/2008, -0/+3For a tech site, many of the people on here seem to not understand how important these sort of announcements are. Sure, it isn't a commercial product yet, but it is the start of a process.
I think it means the difference between people actually interested in science and people interested in shiney, shouty things... - Deeviant, on 09/20/2008, -0/+2Oh good, now in addition to curing cancer daily here at Digg, we also find new ground breaking energy technologies that are definitely not vaporware!

It's not that hard....took less than a minute. - RaDeus, on 09/20/2008, -0/+2i bet you can use this material in Electric reactive armour, imagine Pentagon is going to pounce on this if it works...
- groo68, on 09/20/2008, -0/+2Hopefully improving the strength and lessening the weigh of carbon fiber, so that a carbon ribbon might be made and then a space elevator.
- Slackdragon, on 09/20/2008, -0/+2I'll be glad to see something impressive happen soon. I mean truly revolutionary. I'm 43 and have been reading Popular Science articles for decades touting that we're on the cusp of infinitely lasting batteries since batteries were made. Meanwhile I'm still jamming the same Ray-O-Vac AA batteries in toys for my kids that my dad was crammin' in toys for me.
And, um, I'm still waiting for my flying car and jetpack while we're at it. Damnit, my laptop battery is dying. - unbenamtl, on 09/20/2008, -0/+2It is about a silicon nanowire battery. Yes, the term nanowire is in both articles. However yours talks about using a new material as a node in a chemical battery while the one in this digg is talking about a capacitor, holding a charge and delivering it without an electrolyte - a bit like the capacitors in your computer RAM holding 0s and 1s, but at a much, much cooler level.
- sgvprelude, on 09/20/2008, -0/+2Call Doc Brown!
- robbiedo, on 09/20/2008, -0/+2Resistance is futile!
- unmarked, on 09/20/2008, -0/+2Super-capacitors are the future of "battery technology". They're lightweight, but more importantly, you don't have to trickle charge them like today's batteries. Rather than plugging your car in for 12 hours, you'll be juiced up in 5-10 minutes.
I think once we start getting serious about this stuff -- progress will be quick. This stuff should be top priority right now. - localzuk, on 09/20/2008, -0/+1It comes from an external source, like with batteries - ie. you plug it in.
- kd1s, on 09/21/2008, -0/+1Capacitors can store a hell of a lot of energy. But supercapacitors act more like batteries than capacitors in that they provide a constant current.
The fact that they can make it paper thing and lightweight is awesome. - duke88, on 09/20/2008, -0/+1Never touch capacitors from a CRT TV hold the charge for hours - ouch
- trogdor282, on 09/20/2008, -0/+1Lol no just a regular hummer.
But srsly who wants to wait 15 minutes at a gas station? I think the real future is a Chevy Volt type thing, but with a 400 mile overnight charge not a 40 mile charge. You would only ever need gas if you went on a long trip/vacation. And no, I dont think you could shave any time off the 15 minutes due to the extreme current required. - charlietuna, on 09/22/2008, -0/+1http://en.wikipedia.org/wiki/Supercapacitor

http://physics.bu.edu/~duffy/PY106/Capacitors.html - inactive, on 09/20/2008, -0/+1Just curious, a capacitor stores energy via parallel plates, but where does the initial charge of energy come from? Capacitors can't create energy.....so just curious how this works more specifically.
- LiberalKid, on 09/20/2008, -0/+1I don't think you know very much about Carbon nanotubes.. They're the strongest material currently known to man (over 50 times stronger than high grade synthetic steel) and some scientists have speculated that its the strongest material possible.
- CadMasterAdam, on 09/20/2008, -0/+1***** classic!
- kcpistol, on 09/20/2008, -0/+1Looks twisty all right
- katerpilar, on 09/20/2008, -1/+1i always read about new and exciting stuff but when it comes to real life not much improvement there.
- JrFrenzy, on 09/20/2008, -0/+0Here's the abstract from that paper, just FYI
http://dx.doi.org/10.1016/j.synthmet.2008.04.007 - unbenamtl, on 09/20/2008, -0/+0Anyone got actual links to more specs for the lazy bastards we all seem to be? I wanna know what the disadvantages are compared to traditional batteries, if any. Also, how do you make these? How do you charge them? Are these processes viable commercially and environmentally speaking?
- thegamerslink, on 09/20/2008, -0/+0Interesting on a concept level. I must admit though that the article left a lot to be desired. It sounded more like a fluff we still need grant money piece than an exclamation of viable usability and progress. Sounds like it may be promising and a good place to start any how.
- paperclips4u, on 09/20/2008, -1/+1Some people aren't limited to a vocabulary of common words. You're hatin'. ;)
