There is photographic evidence that there was no heat exchanger on the day the photo was taken. No photographic evidence can prove that the object was not there the day before.
The photos were taken while the reactor was being used. If the heat was real and you removed a 1 MW exchanger while it was being used, you would kill everyone in the warehouse. Even Rossi admits this, so you should not deny it.
The heat exchanger was NOT there. It was NEVER there. Rossi made up the story of the heat exchanger long after the bogus test ended. If there had been a heat exchanger, people would have seen it and it would have shown up in photographs.
How can you say that windows have been there all the time?
Google street view showed the windows were there while the reactor was being used. If the windows were there even one day while the reactor produced 1 MW, it would have killed everyone. Google is not conspiring to frame Rossi. There would have to be massive equipment hanging out of the windows to for an air-cooled 1 MW heat exchanger. There was none.
