A particle with equal size and mass collide with equal
velocity, then the energy emitted would be comparatively high. When lights hit
a plane surface it reflects back and collide with the light particle which was
just behind it and produces energy, heat energy.
If the light hits inclined plane like mountains, lights get reflected
in many angles and reduces the chances for collisions between light particles
and hence heat produced would be comparatively less.
If we closely observe light has effect on the wind as well.
So if my guess is correct, we have rich source of energy in
photons than in nuclear reactions.
Not going to reveal so much in this blog itself, because it
is crazy.
