GK: Using photons as "pure energy" will not answer the question either. A "photon" is a "photon". So what you would have shown is that you "converted" a "photon" into "Matter". Errr, this is done all the time in nature. Turning a "photon" into a usable "thought" ... that is real cool ... and you are doing it in your brain right now.-Good point. Back to consciousness which doesn't use photons as far as we know. But photosynthesis does, by quantum mechanisms.
