Somebody has calculated, at 1MW the steam must go supersonic with
this output tube.
Then, with 100 kW it must still go some 100 km/h.

I got 803 km/hr, which is less than the speed of sound. You may want
to check my calculations!
Using the photos here:
http://www.nyteknik.se/nyheter/energi_miljo/energi/article3264361.ece
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. This is below the speed of sound but over 6 times the
recommended speed for the pipe size.
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 at 50°C I get only 675 liter/sec steam flow.
