I can take my elbow off as soon as I shut the generator off... actually before. Want to try that with that smooth flowing heavy metal elbow that may not mix the cooling air as well?
Listen, I know that you think you have done something great here......and you have, kind of, but you also have missed a couple of important points.
The extra air being drawn in from the bottom is NOT for the purpose of cooling, it is for the purpose of keeping the air flowing.....all the way to the top of the stack.
For that to happen consistently, there must not be TOO MUCH cooling along the way. The walls of the pipe need to remain at least warm in comparison to the outside air. Your thin-walled aluminum pipe won't accomplish that; it might even result in reverse flow at night when the outside air is relatively cold and the top of the pipe cools too much.
I have no intention of continuing to beat you up over this......unless you feel it necessary to keep defending your inefficient design.
