Sending and receiving radio signals while out at sea can require a huge structure not easily constructed out in the middle of the ocean.
‘Superdeep' Diamonds Formed From Seawater
Mitsubishi Electric has a novel solution: SeaAerial, a low-frequency antenna made of sea water.
In the world of radio antennas, this is a first.
The aerial is a conductive plume of water capable of transmitting and receiving radio-frequency waves.
Made of just a pump and an insulated nozzle, the SeaAerial is portable, which means it can be set up anywhere onshore or offshore.

Computer simulations show that radio antenna is 70 percent efficient - sufficient for sending and receiving radio waves.
In a press release, Mitsubishi Electric explained that it developed the antenna as part of a project to find new and innovative materials for building antennas.
Seawater seemed like an obvious choice, since it's abundant and known for its conductive properties.
