VAWT

This parts + https://www.thingiverse.com/thing:2947017
allows for a VAWT equipped with brushless motors. I used racerstar 1400 & 1600KV's for the testing, They are fastened with M3 srews n bolts.
There's also a rectifier chamber to rectify the 3phase into DC. Just add 6x rectifier diodes, 5x screws and bolts, and you're good to go.
After rectifying into DC , it migh be a good idea to add a 'solar charge controller' and a 12v lead acid car accu. it can be a cheap charge controller, mine cost 8$. On fully windy days (+10hrs of wind) it charges a 42Ah car accu, from 10V to 13.6V in 72hrs.
Compared to the 20A solar panel, it yields about the same, but then again, i might have calulated my rectifier diodes wrong, and someone else might yield more.
On playfull wind days, as in then a gust of wind, then nothing, its absolutely worthless. Better use ordinary brushed DC motors then.
