How To Build An Electricity Producing Wind Turbine
This is full-on technical project that will take a lot time, skill and effort to accomplish. That said, the whole system which was built by Mike Davis, costs just $140 to build and it outperforms similar commercial systems costing $750-$1000.
If you are looking for an effective off-the-grid electricity solution and you live in an exposed/windy location, this could be just what you are looking for.
Mike has created a huge, in-depth tutorial on how he created this electricity generating system. It includes the shopping list of materials needed, step by step instructions, videos, plans and lots of photos. It is basically a blueprint for creating your own system.
