Can the process of Pair Production be used as a source for energy generation in space?
Can the process of Pair Production
Creation of an electron and a positron by Pair production. (Photo credit: Wikipedia)
be used as a source for energy generation in space? Can Gamma Rays in space become the source for generating energy using Pair Production process? EM radiation >1.02 MeV enery, Pair Production is the dominant absorption process.

Where is the light energy going?
where is the sun’s light enery going once the sun has set?
or
where is the light going when we switch off the torch facing an object. if light gets reflected how long it will do so. and if it gets absorbed, then will it add to the potential energy of the object that is facing the torch?
or
Is there any cycle (like hydrocycle)to prove that energy can neither be created nor be destroyed?
