Cobalt
A hard, silver-white metallic element frequently used in high-strength alloys and essential for the production of energy-dense rechargeable batteries.
From the video:
's just the one in the name . Cobalt and nickel are also critical to most commercially
Examples
The mining company secured new land rights to search for valuable deposits of cobalt and nickel.
Engineers are attempting to redesign the chemistry of the cell to rely less on cobalt due to supply chain concerns.
A sudden spike in the price of cobalt affected the manufacturing costs of modern electronics.
Geothermal
Relating to or derived from the internal heat of the earth, often harnessed to produce renewable energy or superheat fluids.
From the video:
's why Berkshire Hathaway Energy has built 10 geothermal energy plants in the area , but ,
Examples
The island nation generates a vast majority of its electricity using natural geothermal energy from subsurface volcanic activity.
Engineers installed a geothermal heating system beneath the building to lower annual utility expenses.
Superheated subterranean water from geothermal reservoirs can bring valuable minerals up to the surface.
