Leaving the port of Gothenburg after our mini cruise, A and I obviously had to secure the prime spot for wake watching because I wanted to check out more of the weirdness I talked about in the last blog post. So while we were waiting for the ship to sail, we had the best view of the ship exhausts, too, and it looks really fascinating:
Do you see how the hot exhausts have a very different refraction index than the cold air around it?
Stena Germanica is the first ferry that size running on methanol (super interesting, btw, how the company is exploring new technologies!) so the exhausts are mostly clear.
Although on occasion it does still look a little more like what you’d probably expect of a ship’s engine:
But nowhere near as bad as it used to be! Can you imagine that this is what all ships looked like not so long ago?
Good thing there are tons of regulations in place nowadays, and companies like Stena testing out new technologies.
Can you imagine what Kiel would look like if there was more than one ship making that kind of smoke?
