"I don't see the Sun's output in your calculations. I don't see where you allow for a lack of rigidity in ocean surface and even continental surface. It should be very hard to accelerate the Earth by shooting photons at its water or anything so non-rigid as to absorb the impact by getting warmer. (An increase in very localized molecular motion.) I don't see where you "integrate" the increasing angle of photon impact on the daylight half as one moves away from the area of most direct illumination."
YEAH! I was going to say that too but you beat me to it. Forgetting the suns output: bush league!
