So apparently kickstarter projects are still scams....
No way in hell one turn a second is producing 1 amp at 5V on this thing, not even close.

@freemo I don't even to need to look at the proposal to know this is a scam. You don't need to read any further than the word "limitless" to know it's a scam.
Actually, devices that can produce that amount of power by hand cranking at 60rpm have been around a long time, but they don't fit on a key ring. E.g., a hundred-year-old telephone magneto will produce up to 100V at a few hundred mA. (It's geared to achieve a higher effective rpm.)
@Pat yes larger versions can reach it for sure, not this thing though.. Plus they fail to mention that even if it did produce that much power you'd have to crank it for the better part of a day to charge a phone.
@freemo I think a better idea would be something that would charge it via a passive activity, like something you'd wear around your ankle that would continually charge it all day as you walked around. Kind of like the old mechanical self-winding watches, but it'd be an electric linear magneto instead.
@Pat IIRC i saw something like that which doubled as a knee brace. Though it didnt work too well from what I heard.
