"Just about everything that is now powered by batteries will be improved by this much better energy supply. They can be made in most any size, from postage stamp to hybrid car battery pack. Their light weight and low cost make them attractive for most portable electronics and phones....." |
|
| |
Which is to say this is a pretty obvious use for the technology. |
|
| |
Nothing makes this idea novel, insightful or interesting. |
|
| |
Please to point me in direction of a supercap which rivals a battery (any battery) in the energy:weight region. |
|
| |
Model airplanes frequently use super-caps instead of battery, weight being prime concern. |
|
| |
Whereas my phone battery is almost always flat. |
|
| |
So's your .... um, er ... something or other. |
|
| |
We call it a stomach here. |
|
| |
//my phone battery is almost always flat//
That's because it's not in shape. |
|
| |
still waiting for somebody to show me a super-capacitor what's specific energy comes close to a battery. |
|
| |
It looks like some lab production is getting up
towards NiMH levels (see link), but still nothing to
compare to Li+, and not in general production yet. |
|
| |
So far production seems to be at 1Wh/lb. |
|
| |
I'm a bit surprised(/disappointed) that we haven't seen them in hybrids yet... 100Wh is enough to accelerate/decelerate a 2 ton vehicle to/from 40mph (give or take reality tax). |

"Hi, Bob. How's life at the cellphone design works?" |
|
| |
"Pretty good, Biff, except for our constant search for more battery life. How's life in supercapacitor battery R&D? " |
|
| |
"Still constantly looking for new markets for our products, and I tell you, it's tough sledding some days." |
|
| |
"Heh. I'm always on the lookout, day after day, reading up on energy storage methods and advances, brainstorming, conferring, trying to keep our phones the best in this competitive world." |
|
| |
"And I keep my eyes on emerging technologies, looking for niche markets for our supercapacitor batteries. It's tough work. Sometimes I dream of finding some huge market for electrical storage, something that everybody needs and uses, but that has somehow been overlooked." |
|
| |
"Something right under our noses, you mean?" |
|
| |
"Yeah, within our grasp ... hey, gotta go. This phone battery is going flat." |
|
| |
"Woops, mine too, just as I was about to look at the Halfbakery. See ya." |
|
| |
They're being considered for LED flash guns - such as the ones found in cameras. Imagine a camera that can only produce one flash. Would be a bit naff. |
|
| |
//They can be made in most any size, from postage stamp to hybrid car battery pack.// |
|
| |
A cell phone powered by a car battery would win my vote. Especially if you managed to hide the sloshing, acid filled thing in your hat. |
