@deschoe,
It is nonsense of course.
You will notice that he switches from real experiments, showing capillary action (which we do in high school physics classes) to animations. He does this because at the point he starts talking about "negative pressure" he leaves science into pure bullshit.
This is a fraud.
The answer to the first real experiments he does; the energy comes from the "surface energy" which lowers when the surface tension is disrupted, and from the mechanical work done on the water with the tube being lowered and raised.
The "energy wheel" is, of course, ridiculous.
