The Fuel Powering MASSIVE Cargo Ships🚢 #ship #usa

[00:00:00]You won't believe it, but this thick black jelly substance is the fuel powering massive cargo ships. It's called heavy fuel oil, and it's so thick it must be heated to 175° to actually use it, because if it cools down, it instantly solidifies and clogs the entire system. So, why do they use it? Simple, it's insanely cheap, but it is the dirty leftovers from refining crude oil. It's full of water, sand, and even metal chunks, meaning engineers have to clean the ship's filters every single day. If they miss even 1 day, the engine could completely fail, leaving them stranded in the middle of the ocean.
