Hmm, interesting concept* wonder if there is anyone out there who will notice. I will be participating, always the optimist when it comes to group think, and I hope that the participation is 100%. If our troubled old planet is being observed from other lifeforms in our galaxy an event like this might get their attention. Not only could the light fluxuation be seen, on an hourly basis, but a decrease in energy could be observed.
With a flick of the light switch, we the sheeple will have spoken and if this is successful at all we might consider greater sacrifices as we, “shudder” shut down our computers, telephones, radios, teevee’s, and all the other amenities that we consider indespsensible. With any luck, maybe next year, we could have a “The Day The Earth Stood Still” moment…G:
