Undersea Desalination Pods To Solve Water And Energy Woes
The article discusses an innovative solution to the high energy demands of seawater desalination, a process increasingly critical due to climate change and population growth. California startup OceanWell has developed undersea desalination "pods" that leverage the natural pressure found at depths of around 400 meters to reduce energy consumption by approximately 40%. Unlike conventional onshore desalination plants, which require significant energy to pressurize seawater for reverse osmosis, these pods operate underwater, using ambient ocean pressure to drive the process. This approach also offers logistical advantages, such as avoiding the crowded coastal zones where traditional plants face regulatory and environmental hurdles, exemplified by the decades-long, ultimately canceled Huntington Beach onshore project. OceanWell’s pods also address environmental concerns by enabling more effective diffusion of brine waste in the ocean, reducing the need for costly protective measures. The company has progressed from initial development to testing a single pod in an onshore reservoir designed to minimize ecological impacts.

The Imperial Japanese Navy destroyer Teruzuki, lost for over 80 years, has been discovered off Guadalcanal in the Solomon Islands at a depth of more than 800 meters in Iron Bottom Sound. The Akizuki-class destroyer, commissioned in 1942 and designed to protect aircraft carriers from aerial attacks, was sunk during intense naval battles in late 1942 while escorting supply ships. The wreck was located by scientists aboard the Ocean Exploration Trust’s Exploration Vessel Nautilus using remotely operated vehicles guided by sonar data from the University of New Hampshire’s uncrewed surface vessel DriX. This marks the first confirmed underwater sighting of Teruzuki, whose plans and images were previously unknown due to wartime secrecy. The discovery revealed critical details about the ship’s sinking, including a severed 19-meter-long stern segment found over 200 meters from the main hull, which disproves earlier theories that depth charges caused the ship’s destruction. Instead, sonar data confirmed that American
