That nifty little device works in accordance with the second law of thermodynamics. I was going to bring it up a bit later as a way for you to prove to yourself in your own back yard that there is no such thing as backradiation. Since you mention it, I will provide you a link below to show you how you can point it at the sky and actually cool items put into it and get ice when the ambient temperature is 45 degrees or so. I am surprised that you would attempt to use something that proves the second law of thermodynamics in an attempt to disprove it. That nifty little device absorbs shortwave radiation coming in from the sun and radiates longwave infrared radiation. The warmer long wave radiation from the collector then radiates to the cooler bowl. Exactly in accordance with the second law of thermodynamics. An interesting thing about that nifty little device is that you can point it at the sky, but away from the sun on a clear day and the water will cool to about 4 degrees below the ambient temperature precisely in accordance with the second law of thermodynamics. If there were such a thing as backradiation, the water would not cool to below the ambient temperature as the backradiation would heat the water to some degree warmer than the ambient temeprature. You can take the same nifty device and point it at a clear sky at night and ice will form in your dish of water if the ambient temperature is 45 degrees or lower. Again, in compliance with the second law of thermodynamics. According to the AGW hypothesis, backradiation is happening everywhere 24/7. If backradiation sufficient to warm the surface of the earth is radiating down all the time, how could ice possibly form when the ambient temperature is 45 degrees? Here is a link to an experiment done by the physics department of Brigham Young University. It had nothing to do with global warming or climate change but the result, ie cooling effect when not pointed at the sun and refrigeration at night kicks sand in the face of the idea of backradiation. http://www.think-aboutit.com/Misc/The BYU Solar Cooker-Cooler.htm
