gharnagel , answer the following question, as you love so much
relativity and LCE:

You have a 1 Watt green laser (with an attached battery) placed in the
top of a pole of 100 mt.).
I have no idea what a "mt" is. A hundred mountains? A metric tonne?

On the ground, a receiver (with an attached battery) absorbs such energy

Why do you believe heat is waste? It may not be.

From WHERE comes the EXTRA ENERGY created along the downward path of 100

M and R are the mass and the radius of the Moon.
This PROBLEM exists since 1911 (Einstein's gh/c^2).
Don't you realize that it would exist even using Newtonian physics
if you left out the fact that you didn't include ALL of the energy
input?

Apparently, I see more than you do :-))

Relativity DESTROY the Law of Conservation of Energy, and nobody said
shit about it.
That's because everybody has more intelligence than you :-)))

Go ahead, EXPLAIN THIS VIOLATION OF THE LCE.
There is no violation. You have ignored an energy input: The laser
is at a higher gravitational potential than the receiver. Either
ignorantly or intentionally, you have ignored that potential energy
energy in your calculation. Total energy is H = T + V.

In your situation, T = 0 but there is still V. Consider a modification
of your experiment. The laser is sitting on a lunar mare and shoots
its pulse horizontally to a lunar rover with a receiver. The mare is
flat so V = 0, but the rover is moving toward the laser and receives
a blue-shifted pulse. Where did the extra energy come from? Doppler
shift, of course: T > 0. Whether the Doppler shift is due to relative
velocity or gravitation, energy is conserved.
