Yost said that in general the vertical axis wind turbine with a layer of leaves only difference, he invented the vertical axis wind turbine by the interlocking of the upper, middle and lower leaves of three vertical composition. Because more than two leaves, the area of wind energy retention increased by 200%, while the fan and cut the wind power generation capacity proportional to the area.

Meanwhile, the general vertical axis wind generators, new design that leaves him in the strong winds continued to rotate, you can capture more energy, which will enable power generation capacity by 200%.

According to theoretical calculations, this new structure will make its electricity generating power vertical axis wind turbine than a 400% increase. Preliminary results of wind tunnel tests also support this inference.

Yost said, compared with the horizontal axis wind turbine, vertical axis turbine blade material is not demanding, easier to manufacture, and easy to automate production.

Currently, equipment manufacturing, installation, initial investment cost of wind power accounted for 70%, if the initial investment by 60% the cost of wind power will decrease by 42%. Thus, even without the policy of subsidies, wind power would be a wise choice.

Yost said that they would within two years to 100 kW vertical axis wind turbines put into operation, and 1 MW in 5 years to complete the development of vertical wind turbines.

At present a common horizontal axis wind turbine wind generators, which leaves in the wind-driven rotating around the horizontal axis; while the vertical axis wind turbines, by definition, it leaves the vertical setting, which leaves surrounded by an equally the vertical axis.

Yost said that in general the vertical axis wind turbine contains only a layer of leaves is different from his invention of the vertical axis wind turbine by interlocking the upper, middle and lower leaves composed of three vertical. As two more blades, the interception of wind energy area increased by 200%, while the fan wind power generation capacity and cut-off proportional to the area.

Meanwhile, the general vertical axis wind turbine is different from his new design the plant to continue to rotate in strong wind, you can intercept more energy, this power-generating capacity will increase 200%.

According to theoretical calculations, this new structure will make it generate electricity generator power vertical axis wind turbines than the average increase 400%. The preliminary results of wind tunnel tests also support this reasoning.

Yost said that in comparison with the horizontal axis wind turbines, vertical axis turbine blades of the material is not demanding and easier to manufacture, and easy to implement automated production.

At present, the equipment manufacturing, installation and other early stage investment accounted for 70% of the cost of wind power, if the initial investment reduced by 60% of the cost of wind power will decrease 42%. In this way, even if no policy subsidies, wind power generation would also be a wise choice.

Yost said that they would within two years, so that 100-kilowatt vertical-axis wind turbine works, and a MW within 5 years to complete the development of vertical axis wind turbines.
