Rafay Farooq: Human civilization has progressed a great deal in all scientific fields during its journey from the Stone Age to the scientific era. However, with all its achievements, mankind is far from infallible. Dams are created by highly talented engineers with claims that these buildings are built to stay for centuries to come. However, time and again dams have collapsed and some of them have resulted in major disasters. Here is a list of 15 of the world’s worst dam disasters ever:

Vinod Ramireddy: There is a relatively new technology for generating electricity. It is combined cycle gas turbine and steam turbine using natural gas. If the world would use all energy sources for their highest and most important purposes, we would not be using natural gas to generate electricity. We would be using natural gas for things it does best and that other energy sources can't do as well. But that is not the way the world is working. We use whatever is cheapest for now and don't save precious resources for important uses in the future. That means that combined cycle gas turbine and steam turbine are the cheapest form of generating electricity in places where natural gas is plentiful.
