Twirling battery offers emergency power

Twirling battery offers emergency power

The twirling battery design by Song Teaho and Hyejin Lee offers two minutes of talk time for 130 spins.

An innovative design for a 'twirling' battery could help get you out of a fix the next time your mobile runs out of juice, although sadly the team behind it has yet to produce a working prototype.

The design, developed by Song Teaho and Hyejin Lee and showcased over on design.fr - via Engadget - uses an in-built generator to provide a quick boost of power when the unit is twirled around the user's finger.

Providing around two minutes of talk time for a hundred and thirty twirls - which shouldn't take too long to complete - the system is designed to provide a way of getting power to the mobile for a last call, such as when you need a taxi after a long night out. Alternatively, if you're waiting for an important text, a hundred and thirty twirls will get you around twenty five minutes of standby time.

While the design isn't quite as tidy as competing innovations - such as Nokia's plans to create an energy harvesting handset that would never need charging - it's a neat solution to the problem of finite battery life, and certainly better than carrying around a bulky 'emergency charger.'

There are some disadvantages to the design, of course: it requires that the user take the battery out of the 'phone in order to charge it - something which could be a challenge after a particularly drink-filled evening out - and by its nature is rather more suited to charging small devices such as mobile handsets than higher draw devices like laptops. Despite this, it's an interesting design - and one which the pair hope to be able to bring to production.

Are you impressed by the thought that's gone into the battery, or are you struggling to imagine being desperate enough for a two minute call to dismantle your handset and twirl the battery around like a lunatic? Share your thoughts over in the forums.

I can see people in the future twirling around their phone batteries frenetically as if they were wrestling it.

Seriously tho, when are we going to have in-head terminals that connect to an ocean network through brain waves like the Real Drive anime? We're still way behind twirling our batteries or peeing on them... (Remember that one? Now that's a real battery for drunkards!)

looks good to me if they can get it working

Sounds like a good idea, but what would stop it flying off the end of your finger?
Skiddywinks 11th January 2010, 13:55 Quote
I'd buy one.

Ok, have any of you ever actually twirled anything for an extended period of time? Keyrings, necklaces, tools, you name it, they all fly off very easily. I can't wait for the first "Man looses eye to girlfriends twirling battery" headlines. Wouldn't it make a lot more sense to just add a small solar panel and converter to the largest flat surface on the battery? Or maybe a retractable outlet cord. I mean come on. is this really the best they can come up with?

Id hire a day laborer to spin mine, you know to stimulate the economy. Seriously though good idea and Im glad it isnt being marketed as the new fix for global warming and that if you are not spinning your battery's in the next year Michael Moore is gonna come and **** you up!

Nice in theory, but since most phones loose the time/date settings on battery removal it would be pretty irritating.

Make it into a keyring, turn it into a emergency charger. What with phones going micro-usb chargers (hopefully) you wont need a billion and one adaptors.

+1 Twirling keyring charger would rock :)

@Omnituens

Really? I had an impression that most modern phones contained a small battery onboard that kept the clock running - the clock on my LG Arena, Nokia 5700, Nokia 6500, SE Xperia X1, etc kept running even after I removed the battery for quite some time.

it sure beats the version that you have to shake it back and forth making it look like your jacking off to it lol....

This.

Also, to those that expect it to fly off, if you look at the pictures it is grooved. It clearly looks like it is meant to stick to your finger tightly. It would be nothing like twirling keys.

This but as an LED keychain light perhaps would be more useful.

i've had an idea for a similar concept for a while, something that would be able to absorb the energy from your phone bouncing around in your pocket, on your belt, or in you bag. as electronics get more efficient we could power a number of devices with energy collected from all sorts of places. recall those shoes with little plastic spinning rims that were popular with teenage basketball fans a few years back? i think the implications are pretty obvious...

Surely the section with the hole for your finger could potentially contain those extra minutes of call time anyway...

I don't mean to cause offence, but the designers of this sounds like they are from Japan. Stereotypically people from this part of the world have smaller hands than us larger (fatter) Europeans and Americans.

Most phones update the date and time from the network while they are initializing to the network.

I would rather have more battery then to take up space for the hole and the generator inside the battery pack. Perhaps it would be a better idea to provide a usb or charging adapter that did this, as opposed to the battery itself.

Maybe a charger built into a shoe so that for every step you take it slowly charges the battery. That way people can be motivated to get some exercise...

that is an excellent idea, but it wouldnt have to be in a shoe just something you hook to say your belt loop, and takes that excess energy of movement and changes it to to energy.

What piece of crap phone are you using?

ya I second that, my cell gets its time and date from the cell service itself so its always updated and on time, the only time it runs internal is when I dont get cell service from somewhere but everytime you enter cell service area it updates its time and date at the same time. Is your cell one of those 1980s brick phones?

it would be good for those emergency low batt situations imo :D

Yeah, like when you need to call an ambulance because you've just chopped your hands off ;)

Well my friend. I dont think a solar panel is the best thing you could get when you're wasted 3:00 or 4:00 AM in the middle of nowhere :P

luls, i second paisa, and i personally have twirled things for extended periodsof time, i'm rather good at finger rolling and such (i wanted to learn a few showy tricks with my staff in karate and it carried over). not to mention you could just tie a string to it, ever twirled a cord or piece of rope? it could actually empart more energy to the device depending on the mechanism.

130 spins I wonder how long that would take I mean even if it was 1spin/sec it would take longer to make the power than it will to use it...
