I examined the video frame by frame for the 15 frames that were part of the 15 seconds that showed the end of the black hose -- several frames clearly show the water mist expanding as a cone directly from the end of the hose -- thus no proof that invisible steam made it to the end of the 3 m hose.
Examine the posts by Joshua Cude for clarifications by one far more capable than me... Every day so far is another day without clear-cut proof of actual excess heat output...
