The present test was done on a smaller device  than the 10 kW device that has been used earlier during the January press conference. One of the reasons for going to smaller dimensions is safety according to Rossi.
What makes it potentially dangerous?
The conclusions from the papers  to  are that nickel and hydrogen provide the fuel for nuclear processes inside a small container in a radiation shielded setup and that in the room outside, no radiation different from the ambient one is found.
I don't give a damn about the room outside... are you detecting any kind of radiation emitted from the device itself, right next to the device, with no shielding? If so, what kind of particles, what count rate? Neutrons, photons or what? What does the spectroscopy look like? The detection of ionizing radiation of some kind is of course the signature of a nuclear reaction, and the means by which we observe and characterize and identify that reaction.
The electric heater was switched on at 10:25, and the meter reading was 1.5 amperes corresponding to 330 watts for the heating including the power for the instrumentation, about 30 watts. The electric heater thus provides a power of 300 watts to the nickel-hydrogen mixture. This corresponds also to the nominal power of the resistor.
330 W / 1.5 A = 200 V. What kind of power supply was used to supply the 200 V? AC or DC? What is the actual resistance of this heating resistor? What kind of instrumentation is used to measure these voltages and currents and powers? We can assume that this heating element has a resistance of 133.3 ohms since it is supposedly dissipating 300 W at 200 V, assuming that the "other instrumentation" is connected in parallel across the 200 V supply - but as the heating element heats up, its resistance is likely to change significantly, changing the power dissipation significantly. The heating element is also likely to have a bit of inductance, meaning that error will be introduced if they're careless about measuring real power, apparent power etc. They have not measured anything accurately or described anything accurately. By the standards of basic school-classroom science, they're doing a bad job.
The flow of the inlet water was calibrated in the following way. The time for filling up 0.5 liters of water in a carafe was measured to be 278 seconds. Visual checks showed that the water flow was free from bubbles. Scaled to flow per hour resulted in a flow of 6.47 kg/hour (Density 1 kg/liter assumed). The water temperature was 18 °C. The specific heat of water, 4.18 joule/gram/ °C which is equal to 1.16 Wh/kg/ °C is used to calculate the energy needed to bring 1 kg of water from 18 to 100 °C. The result is 1.16 (100-18)=95 Wh/kg. The heat of vaporization is 630 Wh/kg. Assuming that all water will be vaporized, the energy required to bring 1 kg water of 18 °C to vapor is 95+630=725 Wh/kg. To heat up the adjusted water flow of 6.47 kg/hour from 18 °C to vapor will require 725 6.47=4.69 kWh/hour. The power required for heating and vaporization is thus 4.69 kW.
A "carafe"? For crying out loud, at least try to be taken seriously and use a measuring cylinder or something.
(500 ml / 278 seconds) * 998 g/L (at 20C) = 0.0018 kg/s
Assuming a constant flow rate, an inlet temperature of 18 C, that the working fluid is water, etc, then if the heating element is dissipating 300 W than that alone will heat the inlet water to about 58 C.
If Rossi really wants to convince scientists that this isn't just another Steorn or Lutec or [insert bullshit here], then do the following.
* Put a proper flow rate meter on the water inlet, along with a thermocouple.
* Put a proper flow rate meter on the water outlet, along with a thermocouple. (If it's water and steam, actually, measuring the flow rate will be tricky, but let's just assume that it is conserved and the water doesn't just disappear.
* Put a good leak valve or needle valve with a known, controlled flow rate on the hydrogen line, or preferably a proper mass flow controller. Put a pressure transducer in the reactor vessel to measure the hydrogen pressure.
* Power the resistive heating element from a DC power supply and provide a direct measurement of the current through it and the voltage across it, independently of any other electronics.
* Plug all the above sensors into a data-logging acquisition interface and record them continuously.
* Put a HPGe detector or NaI scintillation detector or something similar next to the device, inside of any radiation shielding, along with a neutron detector. Record the type, count rate, and spectra, where practical, for any type of ionizing radiation that has actually been emitted.
* Record all this raw data from these sensors while the machine is running, and publish it and show us.
