This is really awesome technology. I have recently thought of connecting the boats thru a “mesh” network of wifi routers. It would be awesome if we could use tech for communication between fishing boats and leave satellite phones in the dust.
U.S. Navy engineers at Space and Naval Warfare Systems Center Pacific in San Diego, Calif., have developed a system to use a stream of seawater as a radio antenna. Seawater is pumped through a magnetic probe to receive and transmit communication signals. The frequency and the bandwidth of the signal can be altered by adjusting the height and diameter of the stream.
