well getting a smart drive for under 20$ seems to be out the window and making my own alternator has been put on hold too, so while these 1 metre blades i made from pvc pipe were just sitting around i decided i would attach them to something and see if they work. well they do :D they arent the best and each blade weighs a different amount and its just been tech screwed on to a wheel hub but it still spins! at ground level im getting about 50-60 rpm so up high i should get about 120 rpm (hopefully) and if i balance out the blades and stuff it should maybe put it up to 150 and make it start easier. im not who suggested using a minimill to power some rechargable AA batteries for giving the larger mill a push to get past cogging but it was a good idea and ill use it if i can find a way to do so. my minimill is in this image on the right, i was using its wind vein so i could put the 1metre blades in the right direction. the 1metre blades r just attached to a wheel hub and vicegrips and its me holding it up in the air, gets heavy after a short while.  |
