I think, these 470 kW heat dissipators compare to those of a large truck.
But not to a large truck that is running idle. It compares to a large
truck running the hill upwards under maximum full load for hours.
Under such circumstances most trucks would overheat and must do a pause
or slow down very,very much.

In that case, there was a ceiling, so, even though the windows were
opened, the hot air was trapped.

When I was young, I was working in an aluminium casting house for
some weeks.
This was only one small oven and all windows and large large doors
where left open.
It was incredibly hot inside and for sure this where less than 470
kW heating power.
I was happy I survived this ;-)

was not close to the radiator air exit.
Not open enough. 470 kW is what comes down to earth surface on
470 m^2 on a hot summerday.
Now imagine this amount of energy concentrated on an area of 47
m^2. And this area was less. Probably 25 m^2.

4 m^3/s is not too much. That is a column of 1.6m^2 ascending
at 1.6m/s. The area that concealed the radiators was much bigger.
I feel a hot stream of air if my car stands in front of the
garage, it is still hot and the motor fan is running. My car has
55 kW.
Believe me, the ecat was in sustained mode and running for
hours. Everything in the direct ambient must have been heated up
by this air blow.
There must be MUCH more heat than the Diesel generator was
producing at this time and this does not stay cool.

They test the temperature at the output pipe, but this does
not say much about the energy when the mass flow is not known.
When Lewan looked over the fence to the heat dissipators
then he should have feeled A LOT of hot air. He did not
mention anything.
It would be interesting to know. I have calculated there
must be more than 4 m^3 of hot air (ambient + 80 degrees)
per second.
This is assuming that the air was heated by 80 degrees.
If it was heated by 40 degrees then there must be 8m^3/s of
hot air and so on.

The quality of that video is better than the other
ones. Lewan held the camera steady and explained what
the viewer is seeing. There is less background noise.
By the way, Lewan says he believes input power was
measured using the genset internal meter. This is a
highly reliable method.
The thermocouples used in this test can be seen in
Lewan's video. They are professional quality, and they
are properly placed.
