ITEM NAME:Mini Micro Micro Wind Generator Wind engine Small wind turbine OZ Feature: 1. This vertical wind generator can work regardless of which direction the wind comes from. Compared to conventional horizontal wind generators, the vertical generator can work with light wind, but with strong wind, less power may be generated. 2. Good choice for teaching physical DC wind power generation principle. Three. As the model is completely packed in accessories, you have to assemble it yourself. Just enjoy the DIY fun. Advanced design, high utilization of wind energy, no matter where the wind blows, it can be driven by the wind. 4. Small size, no noise, good demonstration effect, is a very good demonstration tool for DC wind power generation and DIY science education experiment. 5.A major teaching tool for developing the practical skills of children and developing interests.
