Each windmill can be compared to an anti-compressor or expander. The air pushing the windmill blades performs work in order to create electricity and the wind turbine acts as an anti-compressor and, theoretically, the air downstream of the turbine should be lower than air temperature upstream, ever so slightly. The air performs work which is converted into electricity and there must therefore be a temperature drop. C’mon y’all freeperphysicysts help me out thermodynamically and tell me that I am not bullsh*tting. Work is done by the air on the windturbine which nust result in an air temperature drop as per First Law. We cannot create electricity from moving air without a change in temp and press. Environmentalists better realize it. These very changes may just adversely affect the climate if the farms are large enough. Sorry if I busted Greta’s balloon. My advice: Drill baby, drill. C’mon baby, light my fire.
How about (P1*V1)/T1 = (P2*V2)/T2 ?
What are some values, or estimates to plug in?
All true.
Plus, these turbines must be constantly topped off with lube oil. 100s of gallons of lube oil per year, per turbine, if I recall correctly.
The old dirty lube oil doesn’t magically disappear. It’s going somewhere. A lot of it drips down, so in the case off offshore turbines, the dirty oil is going into the sea.
Yes I read that the droughts in some places may actually be caused by the change in wind patterns over the surface of the earth from the turbines. Tehachapi, California has thousands of these turbines and a major drought.
“Each windmill can be compared to an anti-compressor or expander.”
Spot on. The easy version I ask greenie beanies is: If we put up too many windmills won’t the winds slow down?
AND when ever I hear “follow the science” I ask if they know the laws of thermodynamics. Of course they don’t. Then I ask which direction heat goes. They always say up which is wrong.
“the air downstream of the turbine should be lower than air temperature upstream”
Hey, that will counter global warming! Sounds good, huh, but the electricity generated will ultimately produce heat that will cancel the cooling effect.
