I don't buy it. Clearly one has to run power to this transmission device. Once you've drilled a single hole for this all it takes is one tiny wire to vastly exceed the data capacity of this system. You could probably even send data at far higher bitrate over the existing power cable itself.
- klyrs 5y agoWhy is that obvious? Couldn't they use an RTG to power the device without the need for a wire? Though... it does seem like a piezoelectric transducer, or even a relay, could transmit an audio signal through a solid metal bulkhead much more efficiently.
- curryst 5y agoSubmarines often track each other via noise. I don't think you want to make noises loud enough to be heard through a solid metal bulkhead on a regular basis, since the same will likely be true outside the submarine. Those bulkheads are also structural components, I believe, so the metal is quite thick, and the sound would likely echo through the submarine and drive the sailors mad.
