Rossi LENR convinces some but many are not convinced and say it is a fraud

Jed Rothwell gives a positive review of the Hot Cat third party test paper

These people think and write like engineers rather than scientists. That is a complement coming from me [Jed].

In every instance, their assumptions are conservative. Where there is any chance of mismeasuring something, they assume the lowest possible value for output, and the highest value for input. They assume emissivity is 1 even though it is obviously lower (and therefore output is higher). The add in every possible source of input, whereas any factor that might increase output but which cannot be measured exactly is ignored. For example, they know that emissivity from the sides of the cylinder close to 90 degrees away from the camera is undermeasured (because it is at an angle), but rather than try to take that into account, they do the calculation as if all surfaces are at 0 degrees, flat in front of the camera. In the first set of tests they know that the support frame blocks the IR camera partly, casting a shadow and reducing output, but they do not try to take than into account.

Simple arguments can show that the amount of energy claimed by Rossi can not result from the Ni+p=Cu reaction regardless of the isotope. Ironically, people will accept Rossi’s claim that transmutation is the source of energy while questioning whether he makes any energy at all.

ExtremeTech – Cold fusion reactor independently verified, has 10,000 times the energy density of gas

The cold fusion device being tested has roughly 10,000 times the energy density and 1,000 times the power density of gasoline. Even allowing for a massively conservative margin of error, the scientists say that the cold fusion device they tested is 10 times more powerful than gasoline — which is currently the best fuel readily available to mankind.

The E-Cat seems to have a power density of 4.4×10^5 W/kg, and an energy density of 5.1×10^7 Wh/kg.

Steve Krivit slams the report

Steve Krivit says it is not an independent test and calorimetry needed to be done.

The tests seem to show
A COP (Co-efficient of energy production) of 3 and 6 in two tests lasting over a 100 hours.
