US student shows how to listen through steel walls… and send 50W while you’re at it


I hope Tristan Lawry’s found some protection for himself and that he is sleeping in a different place each night. He may end up like John P. Wheeler if he doesn’t.

The fact that Lawry’s device also transmits a significant amount of power — and he says it can be improved upon — means a spook can wander into any lair, stick one transducer on the wall and transmit any signals from inside from a corresponding transducer on the outside of the wall.

No electronic jamming. No concerns about batteries running flat.

Of course, Lawry couldnt care less if the MI6 suddenly has to find a new way to gather state secrets. Hes doing it for the good of humanity and claims it can solve a myriad of design problems.

Submarines are a good example. Because those inside cant collect sensory data from the outside without drilling hundreds of holes through shell for power and data cables, that makes for structural integrity issues.

The same problems arise for aerospace and nuclear engineers.

But for now, it simply means Traistan Lawry’s well on his way to becoming either extremely wealthy… or extremely missing.
