no you are talking about transmission or transformation .
transmission ≠ projection
transformation ≠ projection
words matter a lot otherwise you can convince yourself that something illogical actually makes sense

You know they have a thing that are actually called projector, right? That project an imagine onto a surface. Well what's walk through what's happening there. The projector is using energy from an outlet to then transform it and then project that energy as light onto a surface where it then bounces off it and is then absorbed with our eyes. These things are all intertwined.
ha! i was waiting for this:
electricity-> transformed into light -> then reflected onto the wall
i am probably being annoying with this but energy is not "projected" it is transferred for transformed
power as an organism can be projected or displayed to others
