You continue to skip over the fact that the testing that's allegedly been performed here was minimal at best. I don't see how what SWET did can realistically be called a "validation" or how one can possibly extrapolate it out as claimed.
I don't claim to be a scientist or to have inside information on whether this thing will work or not, but I do know that SWET went for years saying you couldn't prototype it you just have to trust the computer modeling and then, all of a sudden, hey we can prototype it on any old smokestack and then wham bam thank you maam, after a few days of "testing, no tunnels, no turbines, it's "validated"?
Keep the blinders on if that makes you sleep better at night.
