Startup claims breakthrough in turning the earth’s heat into clean power

Of course 50% is a ludicrous number given the height of wind turbines and compared to the height of the atmosphere, but then I’m sure people said “Oh sure, let’s burn all the oil, what could possibly go wrong? Earth is big!”

You are looking at wind turbines as if they were a wall that the wind must pass through. Wind turbines only capture the wind that hits the blades. The wind below, above on the sides of wind turbine blades still keeps blowing. The 50% number only refers to the area of the wind turbine blades. Wind turbines are not mountains.

One effect that has been measured with wind farms is that at night they tend to mix warmer air aloft with cooler air near the surface, which can lead to a small but measurable increase in average near-surface temperatures over time.

Another effect of this mixing is a reduction of ground level fog.

And, of course, the wind doesn’t blow all of the time.

Yes there is a measure for how much electricity wind turbines generate - it is called Capacity Factor.
