I had a 20" box fan laying around and after seeing Muller's work on the 'Web, I thought a box fan could be variable enough to present combinations of power generation schemes for not a lot of money.
The fan has a removable front and back side. On the inside of both sides can be mounted standoff mounts for whatever coils you like. To each fan blade can be mounted a magnet of your choice, or, for more complication, a set of electromagnets with movable slip rings. These (electro)magnet(s) must weigh the same to balance the fan against vibration.
Power output/efficiency can be measured by the usual means. Power storage methods are a matter of choice.
Edmund Scientific in the U.S.A. sells surplus parts that might be useful. They have an Internet site to order from. Digi-Key and All Electronics are first-line distributors of electronics parts. They also have 'Web catalogs.
The reader can decide upon the level of funds expenditure and complication that is necessary to experiment with.
ATTENTION:
I'm relocating to another city on 6/3/09. My ability to answer posts may be delayed for a while as a result.
Will be back later.

I'm living in San Francisco, CA, USA now. Limited funds just to pay rent and buy food.
No camera or scanner on the\is library computer. ::) :-[ :-\
Tito, I recognize, is a European, and may not be familiar with the American industry standard 20" box fan to be used as an inexpensive summer air conditioner? Wal-mart sells them in American for about $12.00. Sorry, no picture to upload! >:(
Besides, it was just a thought experiment to organize my mental impressions. Best I can do with what I have.
