Man, what you should understand here is 'It is not as easy as Extracting Energy from your COW's Dung'. It requires substantial technology to extract energy from this materials like Thorium etc. That is what US agreed to help with us , transfter of whatever technology to make Nuclear power affordable. You should understand that US was the country who exploded an atom bomb in Japan when we were thinking about making GUND(A deewali Fataka). They are at least 30 Years of Technology than any country in the earth.
