<Snipped quote by Legend>
Well, I didn't mean that. I meant that it will detect the being and their appearance and any info that can be gathered will be stored in a database if they met the criteria to begin the process. Then, it wouldn't make sense for a projection of a being to not be somehow connected to the being his or herself, right? And energy, in some form, has to be put in to form and maintain the projection, as well as perform actions through it. The math revolves around the energy that can be detected either within or coming from it.
I thought you meant like a light production. Though, energy itself doesn't tell you very much.
