A Constant Energy Devourer? (Score 1)

Do anybody know the actual power consumption when CELL is running at full speed and normal working speed (if it exist and is not full speed)? While grid computing is definitely an attractive idea, running this on PS3 means it runs on the background when you are gaming/watching, and on the foreground when you rest? Considering the electricity consumption of XBox 360, PS3 is not likely to be much more power-saving. People around me won't like to see such a heat-emitting and perhaps whining monster turned on from dawn till dawn.
