Desalinator
This is another mystery solved by the WhatIsThisThing community of Reddit. One Reddit user shared these photos of this mysterious object that was “washed up on a beach in Florida.” The votes weren’t completely unanimous on that one, but most people seemed to agree this was a desalination bouy.
The desalinator is a power station that turns seawater into fresh drinking water, powered by waves. According to people on the thread, the firm that owns this specific bouy was informed that it has washed up to shore. We never knew such a thing existed, and we certainly wouldn’t have guessed that’s what it looks like. Pretty cool!
