Data Bank Entry

Mineral Distillery

The structure of this device and internal scans indicate a likely utility in processing and extracting minerals out of the water.

The device is engineered to suck water into a superheated primary chamber. As the water boils, steam is forcefully condensed back into a separate chamber that releases the processed water back into the ocean. The minerals that are left behind are gathered in the attached container module.

Activation and control parameters remain unknown.
