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 IIRC i saw something like that which doubled as a knee brace. Though it didnt work too well from what I heard.
@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.
