India’s Solar Lanterns
Just read a post on solar energy. A NPO in India called Sadguru Foundation supplied 100 solar lanterns to socially and economically disadvantaged households in 25 villages in the Dahod district of Gujarat state between January 2004 to December 2007. Professor Govindasamy Agoramoorthy from Tajen University and Dr. Minna Hsu from the National Sun Yat-sen University in Taiwan studied the effect (translate benefits) of the same to the households. And concluded that solar lanterns were not only ecologically beneficial but also safer and more economical.
Considering that the report is quite old now one would expect that the Indian government should have made all Indian villages Solar Lantern villages! But there has been no such progress. However, we hope that more people will make themselves aware of this technology and it will be used in rural households of various developing nations.
Revolutionary Technology
At Choices we are no big fans of forwards but one of our well wishers forwarded something that made us all sit up. On March 27, 09 a piece of news appeared online that has the potential to change the way our world looks and functions today.
MIT is going to announce its patent on an electrolyzer that can enable each house to create electricity for itself by itself!
They have developed a manufacturable electrolyzer made from cobalt and potassium phosphate. This technology, powered by a 6 meter by 5 meter photovoltaic array on the roof, is capable of powering an entire house’s power needs plus a fuel cell good for 500 km of travel, with just 5 liters of water. Its cheap, its efficient, its manufacturable, and it works on Room Temperature!!
This revolutionary technique could translate into an end to big energy corporates, hydro electricity to create which people are displaced, natural order is disturbed, several species are destroyed and because of which atmosphere suffers.
