Jonah rode a whale and there’s the naughty British naval expression of riding the dolphin. Now Norwegian cruise line Hurtigruten reports it will soon sail the first passenger ship powered by LBG. It’s a liquid fuel made up of organic sources from the sea and other waste products.

We can only hope that when the cruise gets underway, and passengers line the rails to wave farewell to those on shore, they won’t have to hold their noses. Seriously, unlike fuel oil and coal, the LBG ships will sail via emissions-free economy.
