In the second photo you can see the blades whirling around.
The components I used are fans:
BP12025M6 FAN 6V DC 2P 120mm 120mm 25mm 10 inches wire 2P terminal connector $4.95 and solar panels:
uxcell 5Pcs 6V 250mA Poly Mini Solar Cell Panel Module DIY for Phone Light Toys Charger 165mm x 65mm. $18.30.
So far, they're working just fine. Total cost: $28.20.
