"Everything in nature contains all the power of nature. Everything is made of one hidden stuff." --Ralph Waldo Emerson
The Hidden Power of Cow Dung
Input: cow dung. Output: enough electricity to light 70 light bulbs, some fertilizer, and heat. Powered by a Stirling engine invented by Dean Kamen, this is an experiment in bringing power to the poor, run by the man who brought cell phones into Bangledesh's Grameen bank, Iqbal Quadir. The idea is that one entrepreneur, funded by a microcredit loan, sets up a business to turn manure into methane gas and fertilizer; another entrepreneur, also funded by micro-credit, buys the methane to power the generator, and sells the resulting electricity. This will, Mr Quadir hopes, unleash all kinds of economic activity. The name of his new venture: Emergence Energy.
