Its long been an issue of concern for deep underground workers but has never really had an answer. How to communicate underground when cell phones and walkie talkies no longer work? Well, turns out that question has been solved by a Los Alamos, New Mexico 16 yr old partaking in the 2009 International Science Fair, which he ended up winning.
Alex Kendrick, has managed to create a system that transmits data using low-frequency radio waves that can penetrate rock more easily than that of high-frequency transmissions. The utilization of this method could mean many things to cave rescue workers and scientists abound. A life saving tool, a method of communicating research studies and much more lay ahead for this system to which Alex has been praised for creating. Impressive if you ask me. What were you doing in highschool? I know I wasn't thinking of this kind of stuff. Congrats, Alex.
