Many people don’t take a shortage of drinking water seriously. After all, everybody knows that 70% of the Earth’s surface is covered in the stuff (except Mel Gibson-hunting aliens, for some reason). We just pull the salt out of that and we’re fine, right? The problem is that desalination of seawater is an energy-consuming process. Recently Dr Verma of the SLIET Department of Physics put forward a solution - floating nuclear reactors which, in addition to generating electricity for nearby heavily populated areas, can use their waste heat to desalinify seawater and render it drinkable.
