Using PC fans as wind-powered turbines - viable idea?
I'm helping to set up the permaculture garden area of a festival this summer and was hoping to make use of some recycled PC cooling fans as mini wind turbines to power some LED lights and maybe a small battery. Would this be possible?
Can you generate a small AC current by forcing a motor to spin? Since PC fan bearings are fairly easy to rotate, I thought these would be a good option.
I realise we'd need a capacitor connected to convert the AC to DC current, but what value? Sorry, I'm still a bit clueless about all this!
