You know of those portable battery-powered fans? I'd suggest using one of those as a generator - take the batteries out. L

I don't know, but I would think you might get that out of a standard 6V motor (spinning fast enough)?

but i think this will burn out even at lesser power input than a mobile phone so it cannot produce a output which suits a mobile phone

They're supposed to run at roughly that sort of power, I only suggest it as something that you could easily try (in the first instance) without spending a lot of time / money. L

yes, but it will present a drag on the vehicle greater than or equal to the power generated by the turbine.

well, an old stepper motor can be used as a generator..then fed to thru a 5V regulator (7805-based or similar or more advanced switching type). I'm not a dynamo specifier, so you'll need to do your own homework on that one. Search the web for "using a stepper as a generator" or use similar terms. that's what I'd do. This stuff isn't a mfg published deal...it's re-engineering product to do what it wasn't made to do, so the specs aren't published for the most part. Maybe someone else has a suggestion of a specific model for your purposes, but I don't. I rather like Lemonie's suggestion m'self.

Lol, so true...And it also dawned on me that I read your query sorta backwards...I thought the load was 55A, not 0.55A, even though you said right up front "mobile", ie, cell phone...doh! That's a novel idea you have there!
