Engineers in the United States are designing nanorobots that look like tiny fish to solve our battery supply chain issues. They aim to pull lithium directly from seawater, a source that holds an estimated 230 billion tons of the metal. 🚀
These bots don't use hooks or nets. Instead, they use special surfaces that grab lithium ions as they swim through the ocean currents.
The robot design mimics the efficient swimming motion of real fish, allowing them to cover more area and collect lithium far better than static filter systems.
This approach aims to secure the raw materials we need for high-capacity batteries without tearing up the earth.
Currently, we rely heavily on mining operations like those in the Atacama Desert. Those sites use massive evaporation ponds that waste water and disrupt local habitats, making this ocean-based method a much cleaner path forward.
If this scales, we might look at the ocean as a battery mine rather than just a place to swim.
Plenty of fish in the sea.
