@Monil-Mansukhani, I get what you mean, but it is necessary to make technological progress. The plan which you devised hypothetically is plausible. "Not every country will have this technology as you" for those countries it would probably be better to no even do that the plan which you devise, they have enough of problems already. Since many countries could not afford to invest enough money mainly Africa and South Asia and many more it would be mainly Europe and America who will engineer the project. This already will deter them since they will be the ones paying most. Also this is a long-term plan, in 20 years there probably will be a better alternative then this. So yeah, it is not that effective
