The most abundant mineral in earth’s crust is something called olivine: pretty in the gemstone peridot, but otherwise pretty useless. Now, New Zealand engineers have figured out how to dissolve olivine to yield silica (50%), magnesium (40%) and nickel-manganese-cobalt hydroxide (10%) for lithium-ion cathodes, leaving only brine.

The shift from emergency water trucking to a solar-powered utility system has slashed water costs more than ten-fold, while increasing daily water production from 700 to 4,000 cubic metres. The project demonstrates how humanitarian responses can evolve into sustainable solutions.
