Chaman Chambu, Who is that eminent scientist you are talking about? You must be sure about his name. You will apply your mind, only when you have to face a power cut of 12 hours in the midst of summer. It is the case in most of MP and UP now, and would be there in rest of the country very soon, if we are not producing energy.
If it is $ 50 billion, then let it be. If we can pay to get that for our comfort, there is nothing wrong in it.
