Rossi: up to 500-550 °C
There's a difference between what you THINK you might be able to do, and actually having a working device that successfully does it, which was my point. As with everything here, I'll start jumping up and down with excitement when I see undisputed evidence from a WORKING pilot plant.
Very good point — unless there’s a working product it doesn’t matter a whole lot. But I find the possibilities interesting which keeps me following the Rossi story.
