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 ;-)

That is open field and and there was wood surrounding the radiator. And even the wood close to were the viewing was done 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.
