100-Year-Old Coal Blocks Still Perfectly Stacked on Shipwreck #underwater #history #discovery

Rectangular blocks stacked inside a shipwreck are not something you see every day. On the wreck of the SS Skaala, these patent fuel blocks are still sitting exactly where they were loaded more than a century ago. Made from compressed coal, they were designed to burn hotter and cleaner than loose coal and were once a vital part of steamship technology. This short takes a closer look at a small but important detail on the seabed, and how a forgotten innovation once helped power ships around the world. #deepwreckdiver #wreckdiving #shipwreck #maritimehistory #underwaterhistory #technicaldiving #worldwarone #steamships
