#46: That avoids violating conservation of energy, but then you run straight into the second law of thermodynamics. You can't extract energy from heat without a temperature gradient, and it costs at least as much energy to maintain that gradient than you can extract from it. (See Stirling engines, for example.)
It is an awesome picture, though.
Phil Plait says it's not diffraction, just an artifact of the imaging process — the probe moved in between taking the three successive color components.
