2. Submarine power cable - Wikipedia

   en.wikipedia.org/wiki/Submarine_power_cable

   Design technologies. The purpose of submarine power cables is the transport of electric current at high voltage. The electric core is a concentric assembly of inner conductor, electric insulation, and protective layers (resembling the design of a coaxial cable ). [2] Modern three-core cables (e.g. for the connection of offshore wind turbines ...

   Pilot and observer. Limiting Factor, known as Bakunawa since its sale in 2022, is a crewed deep-submergence vehicle (DSV) manufactured by Triton Submarines and owned and operated since 2022 by Gabe Newell ’s Inkfish ocean-exploration research organization. [3] It currently holds the records for the deepest crewed dives in all five oceans.

5. High-temperature superconductivity - Wikipedia

   en.wikipedia.org/wiki/High-temperature...

   High-temperature superconductivity. A sample of bismuth strontium calcium copper oxide (BSCCO), which is currently one of the most practical high-temperature superconductors. Notably, it does not contain rare-earths. BSCCO is a cuprate superconductor based on bismuth and strontium. Thanks to its higher operating temperature, cuprates are now ...

7. Submersible pump - Wikipedia

   en.wikipedia.org/wiki/Submersible_pump

   A submersible pump (or electric submersible pump ( ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between the pump ...
