I would like to debunk Rossi and cold fusion and his latest experiment one last time.

The heats evolved are suspiciously close to expected chemical energy for normal reactions. Adding sulfuric acid to water can make water boil. As an estimate, it takes 4 joules to heat water 1 degree C. To heat a kg of water to boiling from room temperature it would take 4 joules per degree per gram x 1000 grams x 80 degrees=320,000 joules.

The report in the url states 470,000 watts total but it says 3 to 4 hours at 10,000 watts minus the 400 watts input for four hours. That sounds more like 400,000 watts (or less) minus the input power.

Watts are Joules/second. In this context, it seems that he is using watts and joules interchangeably because he does not use kilowatt HOURS which would be the correct way to report. This is not a typo because it has been reported this way time and time again. Suspicious in itself but the energy change is almost exactly what is seen in normal chemical reactions. I again will say that some energy is being input to the palladium before the experiment starts. Once it is expended, the mysterious heat evolution ends. Nothing nuclear here, just snake oil.

Don't be - I'm getting a stream of emails myself about this one, and it's getting tiresome to write up the debunk over and over (Frank's is only one of the possible salient points). People are wondering why I'm not covering it on my own forums, as in "are you helping to suppress the 200 mpg carburetor" kinds of tin-foil hat junk from the less-informed. It's nice to be able to point them somewhere where not just me, but many scientists take this stuff to pieces...stops the BS quicker. An ounce of prevention might be painful, but not as much as that pound of cure later.
Why guess when you can know? Measure!

Why? What are they after? Just send them to Rossi's own site, and let's be done with it here;

QRT.
