Room temperature superconductivity, possible but under severe pressure

Starting from hydrogen sulphide, infamous for its rotten-egg smell, a group of researchers at University of Rochester, Intel corporation and University of Nevada in the U.S. have created a material that is superconducting at 15 degrees Celsius. That is, it shows zero resistance to the flow of electricity through it. Such a material would have hitherto unheard of applications from power supplies to quantum computers. The only caveat is that it needs ultrahigh pressure of about 2 million atmospheres to achieve this transition, putting off any thoughts of application to the future. The research, published in Nature, has sparked off animated discussions in the world of physics.
