Today's mineral isn't as simple as it looks. Skutterudite refers to both the naturally forming cobalt arsenide mineral as well as a series of minerals that have a similar chemical structure.
The mineral itself is pretty rare. They can be found as byproducts of hydrothermal alteration in sulfide rich vines. Skutterudite's look is pretty distinct with its bright metallic luster of tin white or light steel gray with a glack streak through it.
Filled Skutterudites families might be the key to clean energy. They are important to the scientific community due to their thermoelectric properties. Research into these minerals boomed in the 1990s due to the technological potential they possessed. Due to their chemical structure, the guest atoms move really fast in a cage-like space, where it doesn't affect or heat up the surrounding structure. Scientists hope to use these minerals to turn waste heat (car exhaust gases, cooling water, heated surfaces on equipment, etc.) back into electricity.
We can't use Filled Skutterudites on a systemic level. However, any discovery that allows scientists to use these minerals to recycle energy would change the world as we know it.
It's kinda fun to think of how the discovery of one small mineral in the 1800s might end up saving the planet one day.
