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.
