Seawater Antennas Not Just Science Fiction

Communiations on the ocean could be vastly improved by a surprising method straight out of the sci-fi books - antennas made out of seawater (SEE VIDEO BELOW).

The US Navy is already engineering a revolutionary scheme to replace its bulky warship communications arrays with antennas composed of jets of seawater shot through electromagnetic hoops.

The salt in the water is the key component that allows the water jet to conduct electronagnetic signals just like a standard metal antenna. Frequency adjustments can be easily made by controlling the height and width of the water stream.

Popular Science speculates that the antennas could serve as compact emergency antennas for civilian watercraft or communication systems on offshore oil rigs.

About the Endurance II Replica Project

An Irish project has been launched on the 150th anniversary of explorer Ernest Shackleton's birth, to build a replica of his ship, Endurance II, in County Kildare.

The project has high-profile patrons such as the Prince Albert II of Monaco, Alexandra Shackleton (Shackleton's granddaughter), and Richard Garriott, the President of the Explorer's Club.

The project is still at the concept stage, so the estimated cost of construction, which is expected to be around €14m, and the annual operational budget of €1.5m are not yet confirmed.

The project organisers are seeking $600,000 (€556,350) from 12 "founders," who will each contribute $50,000. The chairman of private investment firm Kilcullen Kapital Partners, Galway-born O’Coineen, bought the Business Post newspaper in 2018.
