Very smart source of energy!

The Battery for those that pleasure themselves a lot

This could effectively eliminate chargers if they make it effecient enough. I’d buy it the second it hit shelves.

wonderful concept keppt it up

Wow, this is awesome design! Better than those shakeable flashlights.

I think it is a bad idea compared to pulling a string or a nylon cord to recharge something….

because pulling a cord like a lawnmower starter makes 2 hour of standby in 1 minute compared 25 minutes with finger power.

A bit awkward as it is but the concept has legs

awesome, i hope they sell it and its not just an idea like many

very interesting.
nice design also.

I can see batteries getting flung across the room everywhere.

Hmmmm… if the volume/room used for the finger and generator were used for a second small backup battery, and there was just a little switch to do a transfer……

coool ideal

Nice project. ı see it before seiko swatchs.. Generaly same

@raidorf
Okay but size is what matters here. If we were to attach a lawnmower cord and a generator to our cell phones it would defeat the purpose.

Okay. Good idea. But what about FINGER size? Are there going to be different sized batteries? What about people who don’t have average finger size (i.e. large or small)? Are they left out of the mix now?

does not have to be finger. we can use pen or pencil or whatever to rotate it. i believe it helps make it smaller

I work at a battery store and i have no idea how this would work. cell phones are all 3.6 volt systems or close to it. not 4.7-6v. and what chemistry would it me? li-ion? idk just doesn’t seem to be explained.

Need to make a car battery I can swing around like that..

I need one of those for my car!!

As we couriers are on the road every day there always comes a time when we may have forgotten the phone charger cable.
This idea would solve the problem enough until you got back.
Brilliant, I want one.

This is awesome. Too bad the iPhone doesn’t have a removable battery. Would be cool if the iPad allowed for users to take the battery out, spin it around a few times as it gathers juice, then pop it back in. Speaking of iPads, this company is giving away an iPad for just registering

haha about as useful as a flashlight you have to shake to see for 30 seconds.

And the one problem with efficiency is that even a perfect system can only provide as much energy as what is put into the system. And spinning an object around your finger does not provide very much energy to be stored and used later.

this seems like a good idea, but to spin it 130 times to get 2 minutes of use out of it seems pretty useless… it would give you just about enough time to make a call, and say hi, then lose batter power again. if it was made much more efficient, then it would be very useful.

good job though, awesome concept. keep it up!

I already had this idea, to bad I don’t ever try and get patents produce my genius ideas.

Removing the battery cover and removing the battery to swing on your finger is just poor design. Not only does it make the recharge process a hassle it has potential risk to fly off your finger get lost or get sand on it, etc.

The better way to do it: Just spin the phone on the table (or between your fingers) like spin the bottle = no battery removal, same centrifugal force. Idiots they wish they were as smart as me.

@Anoni Moose
that would kind of defeat the purpose.

nice idea … just one problem tho, for smart phones like blackberrys & iphones, they take ages to restart so it would be annoying to take the battery out everytime you wanted to recharge it! get what i mean?
