The sun provides energy in the form of radiation that can be transformed directly into electricity with photovoltaic panels.
We can also transform solar radiation into mechanical energy, for example by using the vaporization of a fluid (Minto wheel) or by capturing the energy of the wind (movement of air masses heated by the sun) or rivers ( sea ​​water that the sun evaporates, which gives rain and streams).

There is also a phenomenon directly resulting from solar radiation. A mirror, for example reflecting the sun's rays, has been subjected to pressure. The effect is weak and I do not know of any common full-scale applications, but the solar sails used by some satellites use this principle.

This phenomenon is also used to move or exert pressure on molecules using a laser.

It might be interesting to mention but I don't know if we can get much from renewable energy point of view.

So if I understood correctly, mechanical solar energy is all of the other existing energy thanks to the sun ...

Tell me if I'm wrong: helicopter and hydrolytic energy, so it's mechanical solar energy since rivers and winds are linked to the sun.

It is effectively solar radiation transformed into mechanical energy through air and water.

Hihi I know one who would have had a stroke ...

Here, I have a glue: we write well hydroelectricity and not hydrauelectricity ... pkoi ca?

Very good question and it is not the only one.
This is the logic of the spelling or should I say the absence of logic :|

Wrong!

In French, the otrhograph is quite logical, you just have to look for the roots ...

In this case, we are dealing with a "false-friend" since the common root is "hydr -" (from the Greek "hudôr" = water), but completed with "aulos" (pipe) in the case of hydraulic.

So hydropower happens without pipes? : Mrgreen:
