Device Made for the Moon May Aid in Carbon Sequestration on Earth

by Bill Morris 7 October 20227 October 2022

A pocket-sized device intended for use on the Moon could soon play a key role in Japan’s ambitious plans to sequester carbon dioxide.

A small coastal shipping town in Japan is devastated by an earthquake. In this photo taken from a plane, the wreckage of hundreds of buildings can be seen, and only a handful remain standing. In the center of the image, a small yacht is perched on top of one of the only remaining buildings. The town is surrounded by mountains and forests. One of the plane’s wheels is visible in the lower left corner of the image.
