I hope I can buy one of these soon, it would be pretty handy. Actually what I’d want is a device to recharge my PDA. I doubt that the turbine or the magneto would put out enough current/voltage to charge the LiIon pack in my Viewsonic V-36. I can’t tell you how many times I have been reading it and all of a sudden the low battery warning pops up. If I don’t shut it down ASAP the memory will corrupt. Its a dumb design, but then again it was less than $200US..
Using air to charge cellphones? IIT-Delhi does it!
