So this big black box is a radiator? it sure doesn't seem like a radiator to me.
Aren't radiators supposed to... radiate? I don't see how a boxy, square design efficiently radiates.
There are visible pipes, going upwards. Maybe Rossi was filling the upper floor with pixie dust? everything is possible, now that we know Internet Experts can explain how a company, its investors and their scientific teams were fooled for 2+ years (along with, for good measure, the swedish and italian scientists examining Rossi's works).
What's really amazing is that they were fooled by the reactors they built and tested themselves... I guess I'm going to take Flat Earth Theories much more seriously, now that I know how a couple Internet Experts can really identify flaws and misconceptions emanating from the conclusions of unrelated PhDs from various countries.
