I did some plausibility calculations for Rossis 1 MW plant.
Thermal Energy of saturated steam @1bar, @100 centigrade = 2675 J/
g (taken from an industrial steam table)
10^6 J*s^-1 / 2675 (J/g) = 374 g/s.
Volume of steam = 1.7l / g
So steamflow = 636 l/s = 636 cm^3 / s
If the crosssectional area of the output pipe is 10^2 cm, then the
steam speed is 6.36 m/s.
If the COP is 6 then the input power = 167 kW.
At 380 Volt the current is 439 Amperes.
I think they use 380 V 3-phase current in industry in US.
The single phase voltage against the neutral zero conductor is 230V
in this case.
(I dont know the precise english words for this. Hope it is
understandable)
So this all sounds reasonable.
I post this as is, you may use it or check for errors ;-)

The photos are here:

The outside width of a standard container is 8 feet, or 2.44 meters
From the full photo of the back side:
The 8 feet = 129 pixels
The red handle = 16 pixels = (16 px)*(2.44 m)/(129 px) = 30 cm, much
larger than I would have thought.
In the closeup photo the handle is 94 px, giving (30 cm)/(94 px) =
0.319 cm/px.
The cap is 40 px, or 12.8 cm OD.
The exit pipe appears to have a 22 px OD, or 7 cm OD. Maybe the pipe
is 6.5 cm ID, or 3.25 cm radius, giving an area pi*(3.25 cm)^2 = 33
cm^2.
The energy put into the steam depends on the temperature to which it
is condensed before being fed back into the E-cat.
Assume the condensed water is being fed back at 100°C.
The energy to vaporize water at 100°C is 2260 J/g. If 1 MW is
heating 100°C water then I estimate the flow has to be 442.5 gm/s,
with a volumetric flow of 737.5 liters/sec. This gives a flow
velocity of (737500 cm^3/s)/(33 cm^3)= 223 m/s in the pipe, or 803 km/
hr.
If I did the calculations right, then this indicates the device could
blow up. If there are emergency steam relief valves on the devices
the steam could be released inside the container.
Note, if water is fed back a 50°C I get only 675 liter/sec steam flow.
Side note: the 52 E-cats at 80 kg each should have a mass of 4160
kg! I wonder what the shipping cost on that is?
