Investing in commercially available renewable-energy devices usually requires large capital investments and long payback periods.
This farmer has explored a low-cost alternative.Low-tech wind power offers farmers an alternative approach to the problem. The Vertical Axis Wind Turbine (VAWT) design that has resulted from our research provides useful amounts of generative or rotary power yet can be assembled at a material cost of under $1000.
The design is freely available and can be executed using common materials and skills.
