The US Navy has created a device which turns a jet of sea water into an impromptu liquid antenna, creating a powerful, high frequency broadcast tower for ships, emergency situations and easy transportation.
Created by SPAWAR System Center Pacific, the sea water antenna uses the magnetic induction properties of salt to make ordinary ocean water transmit and receive radio signals. As the pillar of water is squirted through the current probe, a magnetic field is created and signal comes through to a hooked-up communication device.
Plus, depending on the height of the stream of water, you can get UHF, VHF and HF broadcasts, all from the same jet of H2O. You can even set up multiple jets of water, at different heights, to broadcast on different bands simultaneously. Handy.
