Its new Water cooled EV, page-6

the moron brigade are beyond belief in their stupidity really -

even joking about EV's - electricity and water doesn't mix

uh huh

what do they think powers UWV's ???? ----------- old motor mower Briggs and Stratton engines?


The deepest underwater vehicle is *Nereus*, which successfully reached a depth of 10,902 meters (35,768 feet) in the Challenger Deep of the Mariana Trench on May 31, 2009. This makes it the deepest-diving vehicle ever utilized for ocean exploration, surpassing previous records held by other vehicles like the U.S. Navy's *Trieste* and the Japanese *Kaiko* [2][3].
### Power and Design
*Nereus* is a hybrid vehicle, meaning it can operate both as a tethered remotely operated vehicle (ROV) and as an autonomous underwater vehicle (AUV). When operating in ROV mode, it is controlled from a surface ship via a lightweight, micro-thin fiber-optic tether. This tether allows for real-time control and data transfer, which is crucial for deep-sea exploration [2][4].
In terms of power, *Nereus* is equipped with approximately 4,000 lithium-ion batteries, which provide the necessary energy for its operations at extreme depths. The vehicle's design includes buoyancy provided by about 1,500 hollow ceramic balls, allowing it to withstand the immense pressures found at such depths [3][4].
This combination of advanced engineering and innovative power solutions enables *Nereus* to conduct detailed explorations of the ocean's deepest regions, collecting valuable data and samples for scientific research [2][3].
