Interesting way to generate electricity for yourself while at remote locations

Seems like an awful expensive gadget for just being able to recharge your cell phone or ipod . . .

I wonder if you could get larger blades and make it for wind. Cooling the generator may be a problem in the air.

am thinking in the woods, no sunlight, you need electricity. not for backpacking. more for the RV dweller boon-docking in some remote location. People complain about getting too hot out in the open during the summer trying to keep cool. well if you put this isn a stream, you can maybe run a small fan all day while not discharging your batteries.

am starting to think the thermal phone chargers that work with a small camp stove, that have a thermal charger built into them, might be a better competitive option?  if you are under heavy tree cover?  Have seen them advertised, but not sure where the technology has gone so far.

It would be so easy to find just the right stream to power this, I think Goshawk should invest.

Forget it.  Most micro-hydro needs/wants a 10 foot (3meter) fall.
Just using the 'level' stream won't produce anything usable.  Remember the law of diminishing returns; you can't get more out (or even equal) then put in.

Its basically windmill, which wants to turn the final rather fast, and if a reverse gear ratio, you need a lot of mechanical force.

I've looked into all the alt (electrical) energy stuff. Nothing is great.

(yes I'm a curmudgeon.  But I learned early on that a good engineer spends a time figuring out why something won't *work*.  Saves the effort, money, and time going forward too soon.)

Thanks for the comment. Was wondering about the quantified resulting power.

On to the next perpetual motion machine ? Lol. Does anyone have a heat exchanger working with a stream for improve air conditioning? And is that possible?
