First Wind-up Phone Charger Review
Jonathan Bennett writes "Here's the first actual review (as opposed to speculation) of Motorola's FreeCharge hand-operated mobile phone charger. Only works with Motorola phones for now, but other devices on the way.

For years, I've been excercizing for this product, once, twice, or sometimes even three times a day. At last all that hard work and repetitive motion will pay off.
And if I can get one of those phones that can view color photos, I might be able to continue excercizing after I've charged it.

Her: Ew! Pervert! *click*
Me: *pant* Wait! *pant* Damnit!
Maybe this isn't a good thing...
According to the article, there is no clockwork involved in the charger. The handle turns the generator directly. The box is already larger than a cellphone, so why not include clockwork? Instead of using hand power to turn a generator, why not use handpower to compress a spring (at a significant mechanical advantage, of course) that turns a flywheel that turns the generator.
Of course it would be much harder to turn the crank, but you wouldn't have to keep up an exhausting pace of over 100rpm. At least in my mind, I'd rather turn a very hard-to-turn crank 10 times than an easy to turn crank 1000 times.
Does this model work? I've seen it work in some of the various other 'squeeze and go' utilities out there. I had a flashlight/FM radio combo a little while back that used something similar (handle, spring, and flywheel arrangement). It was relatively hard to crank, but one or two cranks got you 30 seconds of flashlight or 5 minutes of radio at top volume.
The next Slashdot story will be ready soon, but subscribers can beat the rush and slashdot the links early!
"This is nothing more than a dynamo flashlight or disaster radio without the bulb or radio."
What kind of long distance rates are you getting with your dynamo flashlight?
One use they don't bring up that they should is being able to use cell phones where there isn't any electricity to charge them. In a lot of the poorer countries they are going straight to cell phones and skipping laying copper. The lack of electricity to charge the phones has been one of the stumbling blocks for getting phone service to some really remote areas.
