The heat exchanger is your last best hope
No, it is part of mountain of proof that Rossi lied. It is one of dozens of data points. The pretend data and sequences such as 36,000, 18,000, 36,000 also prove he lied. You have not disproved a single one of these things. You have not even addressed the math that shows the heat exchanger would not work even if it were real.
You think that by casting doubt about one trivial detail or another disproves the whole story. You imagine there might not be glass. Anyone can see there is glass, but you and a child imagine there isn't. That fact alone overrules other photographs both inside and outside, eyewitness testimony, and the common-sense observation that Rossi would show people the heat exchanger, and he would preserve it, because it was worth $89 million to him. He would take photos of it. You will not discuss any of that, or acknowledge it. Your phantom imaginary missing glass overrules all else. You are grasping at straws.
