Hi Doug,
I posted about:
Small-scale wind power for everyone: New turbines operate from just 2.7 m/s - NotebookCheck.net News
You posted something about a vertical-axis wind turbine (VAWT), while I posted about a horizontal-axis wind turbine (HAWT).
I place the two photos next to each other to help you understand the difference between VAWT and HAWT. ![]()
