One of my favorite websites, Green Daily, has this link to an announcement of a solar powered refrigerator: http://www.greendaily.com/2008/08/11/who-wants-a-solar-powered-a-c/ I have posted about solar powered airconditioners before but this design works on DC and directly runs the airconditioning unit without any converters etc required. Some big names are testing Greencore's http://www.greencoreair.com/ products including MacDonalds and the US Armed Forces. Shouldn't companies in South Asia be checking them out? With the sun shining down on cities like Chennai, Mumbai and Bangalore for many days every year, this could be an excellent product for use in India.
High tech is something that Indians associate with software alone. I wish they thought of other fields which could be equally high tech and did some work on them as well.
