A Vessel Called “Hidden Gem” Launches into the Depths of the Sea “The Collector”, A 90-Ton Device to Collect Rocks Rich in Minerals.
Forget traditional vacuum cleaners. We introduce now the largest one you’ve ever seen, but don’t worry, it wasn’t made to clean your house. In a surprising innovation, a “vacuum” weighing 90 tons is being used to suck rocks from the ocean floor.
And why does this matter? These rocks are rich in minerals such as nickel, cobalt, copper, and manganese, which are essential components in the manufacturing of batteries for electric cars, wind turbines, and solar panels.
From Oil to Minerals
Originally built for oil drilling, the vessel “Hidden Gem” was revamped by the startup The Metals Company to serve as a floating base specialized in collecting these rocks. In its first operation, the company managed to gather more than 3,000 metric tons of material.

No more TV stuck on the wall: Samsung The Freestyle+, the new projector with over 400 lumens projects on walls, floors, and ceilings, bringing cinema to any corner of the house.

A Japanese governor single-handedly stalled the construction of the world’s fastest train for nine years, and only now has he agreed to allow a tunnel excavated at a depth of 1,400 meters.

Almost 1 billion euros, two gigafactories, and a million-dollar public investment, Chinese company aims to turn Spanish city into Europe’s new battery hub.
The equipment is lowered from the mother vessel “Hidden Gem” to the ocean floor. Operators in a control room take over the commands and start the “cleaning.”
Equipped with four suction nozzles and sensors that adjust its position according to the irregularities of the seabed, the “vacuum” collects the rocks and sends them to a special compartment in the vessel.
An Underwater Treasure with Implications for Electric Cars
These rocks, known as polymetallic nodules, are formed by millimeter-thick layers of useful minerals and can be found in flat and smooth parts of the deep ocean, such as in the Clarion-Clipperton Zone, located between Hawaii and Mexico.
Although the company claims that this method of mining is safer for the environment compared to traditional mining, there are concerns about the impact on marine life.
The ocean is home to countless species that are yet to be discovered, and this activity may put ecosystems already weakened by the rapid advancement of climate change at risk.
The Future of Minerals and the Environmental Challenge
Given the growing demand for batteries for electric cars and other clean technologies, the potential of these oceanic rocks is immense. However, stringent care is necessary to ensure that the exploration of these resources does not result in irreversible environmental damage.
In summary, the oceanic “vacuum” represents a milestone in the extraction of minerals that are vital for the global energy transition. But as the saying goes, it is better to be safe than sorry: in-depth studies on the environmental impact of this activity are essential to ensure a more sustainable future for all of us.
