[Peripherals] Savonius Wind Turbine ideas

[info at olpc-peru.info]

Hello Ixo,

* copper wire   (I wonder if using insulated wiring would work?)

No.  Copper must be "naked" to get maximum efficiency.

* magnets   (the better the grade, the better electricity..  but I 
wonder if hard drive magnets would work?)

Are they different than normal magnets?... if they are like normal 
magnets then we can assure that "stronger" the magnet power that they 
have then "bigger" electricity that they can generate.

This would be so easily to replicate ,  if these supplies were readily 
available... In Peru, how common are these ?

Copper coiled is easily available in many places, there is a lot of 
technicians that repair TVs and radios (and small motors).  All of them 
know very well how to work with coiled copper and magnets.  Copper is 
easily available.  Getting the right magnets is the real problem (as far 
as I can see, here, in Peru).

If I can be of any help for your test or energy generating pilots just 
let me know.

Best regards

Javier Rodriguez
Lima, Peru
