Not sure if that is the correct summary, but anyway thank you for the input.
I am just starting to look into this subject and I will see what happens when I get to know more.

The question is if tidal forces by the Moon are the only relevant frictional forces on the Earth.
If other frictional forces are active, this would suggest an invisible energy supply from outside the Earth.

Here is a link to the original scientific paper:
