why dont windmills spin on the vertical axis as that would be omnidirectional for wind? (lemmy.ml)

This actually exists https://en.m.wikipedia.org/wiki/Vertical-axis_wind_turbine

Here's the specific bit relavent to OP's question:

VAWTs often suffer from dynamic stall of the blades as the angle of attack varies rapidly.

The blades of a VAWT are fatigue-prone due to the wide variation in applied forces during each rotation. The vertically oriented blades can twist and bend during each turn, shortening their usable lifetimes.

Other than the drag-types, VAWTs have proven less reliable than HAWTs,[20] although modern designs have overcome many early issues.

VAWT = vertical axis wind turbine

HAWT = horizontal ...

So HAWT in here!

Horizontal Axis WInd Turbines. So HAWT right now

This has drifted so far away from the original question

I don't know why, the big fan is on

So TL;DR it's worth the extra bearing for the added efficiency unidirectional wind flow allows.

Didn’t one fall over a while back in NYC area?
