Postscript - written last. It's rubbish. Indian rich "innovators" ripping off Indian BOP poor with help of US expert in disrutibe innovation (possibly out of his depth technically?)(you'd hope not). And a substantial devlopment grant from a US benefactor. Power supply is a "jazzed up" "laptop type supply". I wonder how mains modulated much ripple it has on it? I wonder what the Peltier lifetime is or if buyers are told? ___________ Here's an example that may be an example. The gist of this article is that it is a fantastic new low cost, low energy use high tech solution of the poor's (under $US5/day income) refrigeration needs in India. To me it looks like a dressed up overpriced Peltier based Cooler which will almost certainly have a very low active element life, poor energy efficiency, and low performance. http://www.gizmag.com/refridgerator-rural-india-chotukool/13680/ $US69 for a Peltier cooler seems a bit steep in the context.. ________________ Gargoyles ... Looks as bad as one would expect, alas. This moderately long discussion gives no indication that it is anything other than a (POSSIBLY well designed) Peltier coolbox. http://innovation.hindustantimes.com/summit-news/the-new-cool-mass-market-g= odrej.php Yeah.
