Does the air disruption truely affect energy usage in this particular situation? Answered
I was reading the comments in this Ible: https://www.instructables.com/id/Parasitic-Wind-Turbine/ and they said that having the turbine in the way of the airflow would create more of a load on the A/C thereby causing it to use more energy. I don't understand it in this case. I can see how putting it in line, mounted to the exhaust port, thereby blocking the exhaust would restrict the airflow. I don't see how using the already exhausted air would restrict the airflow. That, IMO, would be like saying that when you are stopped at a red light and another car is behind you, your engine is working harder because that car is behind your exhaust. Am I thinking right on this?
