Dear esteemed wrenches, I am working for a school who were donated several SolAir wind turbines. I am trying to figure out if they work. Anyone have any experience with them?
By the swept area they are likely 250W machines, (even though they were sold as 1.6KW). I am just wondering if they work, and how well, so we can find a use for them.
