There are, occasionally, questionable stories that come up in the media especially when star-struck reporters and editors do not bother to check up on a story's antecedents. This happens most often with media outfits that promote a specific ideology, and, India's Communist newspaper, "The Hindu" seems to have fallen into this habit with this story: http://www.hindu.com/2009/03/28/stories/2009032854610700.htm
While I do not wish to slam some young kids for a fraud that has, almost certainly, been perpetrated by some crooked science teacher in their school, I wonder how difficult it would have been for The Hindu to figure out that such a design was mooted by an African NGO based on tribal designs that have been used to keep food fresh in that part of the world for centuries? Or that Treehugger had slammed an attempt by a US based business that wanted to patent this same idea in much the same way that this school wants to? Here is where Greenwashing is clearly at play with a liberal dose of BS piled on top by a newspaper out to prove a point. The sad bit is that there are many two bit Communists and jingoists in India who would cheer and applaud at this unfunny joke. A sad state of affairs to say the least!
