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.
