Step 7Trial run
You now have a nice lightweight turbine to bolt to something heavy. Unfortunately I had little wind for one of the videos - the unit goes great above 10 kilometers per hour but this short gust is the best I could get yesterday.
You can see from the little coloured toy windvane that even though there's no wind, it starts in the lightest of breezes. It has a truckload of torque too when the wind is aout 20 kilometers per hour.
In the second video I have added two large blades from large domestic garbage bins. I tried grasping the broom handle and stopping the centre shaft coming out the bottom - too much torque! Tonight I'll add the other two blades. With a much larger blade radius I should be able to pull a lot more watts off of it!
