Critical configuration for different machine types

It was shown in the preceding section that the maximum lift coefficient is likely to exceed the maximum drag coefficient for a wind turbine blade, so consequently the maximum loading on a stationary blade will occur when the air flow is in a plane perpendicular to the blade axis and the angle of attack is such as to produce maximum lift. For a stall-regulated machine, this will be the case when the blade is vertical and the wind direction is 70°-80° to the nacelle axis, whereas for a pitch-regulated machine the blade only needs to be approximately vertical with a wind direction at 10°-20° to the nacelle axis.

Solar Stirling Engine Basics Explained

The solar Stirling engine is progressively becoming a viable alternative to solar panels for its higher efficiency. Stirling engines might be the best way to harvest the power provided by the sun. This is an easy-to-understand explanation of how Stirling engines work, the different types, and why they are more efficient than steam engines.
