[QUOTE="Lindt, post: 642937, member: 1668"] A few things about wind energy: The energy you can extract from moving air is related to the swept area of the blades. Big/long blades or blades that spin fast. First is impractical unless in a fixed location and the second results in noise and rapid wear of components. Turbulent airflow has little energy. Wind turbines of all scales need laminar flow which is why they need to be tall to get the best clean air. This is also why urban wind installations perform poorly. Same goes for in a treed campground or even a caravan parking nearby Solar or a methanol fuel cell (if you’ve hit the mother lode) for quiet reliable power with good batteries and controller. I know jack about finding gold but have some practical experience with energy. [/QUOTE]
