Route planning has started on the pan-Arctic submarine cable that could link Europe, North America and Asia via the Northwest Passage – the latter opening as formerly permanent ice yields to climate change. The idea of the project, dubbed Far North Fiber, is to terminate in Japan, Norway and Ireland, and have branches to Alaska, Canada and Greenland (see map). ...

X1 Wind’s X30 prototype floating wind turbine has delivered power though its 1.4km sub-sea cable to the Canary Islands’ Plocan off-shore laboratory. “Local teams will now enter the last phase of a test and verification programme which started with the platform installation in November 2022, in preparation of the technology industrialisation and certification for commercial scale projects currently under development,” ...

Researchers at MIT have produced a prototype water purifier that can turn cloudy seawater into drinking water using ~20Wh/litre. Developed under electrical engineer Professor Jongyoon Han, the unit fits into a small suitcase, and relies on multiple stages of ‘ion concentration polarisation’ (ICP), followed by electrodialysis to reduce residual salt concentration. ICP, pioneered by Han’s group, applies an electrical field to ...

UK connector maker Harwin is to sponsor the 2022 GB Row Challenge, and helping to develop on-board seawater sampling equipment. “First held in 2005, the competition is a continuous circumnavigation of mainland Britain,” according to Harwin. “Starting at Tower Bridge on 12th June, the teams will embark on a 2,000 mile route.” “Harwin is the principal sponsor for two of the ...

A 2MW combined solar power and desalination plant is to be built by the European and Gulf researchers and companies. It is part of a project called ‘Desolination’, intended to improve the efficiency of both concentrator solar power and desalination. “Not only will improvement be made on the independent systems but also on their coupling taking advantage of the mutual interactions ...

GradConn’s has added stainless steel corrosion protection to its already very waterproof range of SMA cable assemblies. With stainless steel (303) SMA connectors, the assemblies are rated to IP67 and IP68 and, for the first time in the Nautilus range, IP69K against high-pressure and high-temperature wash-down. “The SMA interface makes it one of the smallest solutions in the market specified ...

Saildrone is a Californian company which designs and manufactures wind and solar powered autonomous surface vehicles, called Saildrones, designed to monitor the ocean for months on end. The hard wind design emerged from a decade-long pursuit of the land speed record – company founder Richard Jenkins ultimately achieved 126.2mph in 2009, having started his Windjet Project in 1999 while studying mechanical ...

Mitsubishi has invented an antenna made from sea water. Branded SeaAerial, it shoots a column of water into the air to create a conductive plume for transmission and reception. “A plume of seawater can be used as an antenna if it is insulated, so Mitsubishi Electric developed an insulated nozzle that transmits radio waves to the antenna even when the ...
