For the last 35 years, this amazing hole has been burning incessantly. The underground cavern was discovered by the geologists who had been drilling for gas in the small town of Darvaz. It was ignited so that no poisonous gas could sneak out of the hole, making it look like an inferno! Eversince then, the hole made enormous publicities under the alias given by its locals --- 'The Door To Hell'.
But wait...no one tried to convert this hole into a source of energy? It would have been an excellent one.
