Per ton-mile, they're far and away the energy- and emissions-cheapest form of bulk transport we have. Someday, we'll pull container ships by high-altitude kite

Per ton-mile, they're far and away the energy- and emissions-cheapest form of bulk transport we have. Someday, we'll pull container ships by high-altitude kite or something, but until then, 50+% thermal efficiencies aren't something to dismiss out of hand.
- Zigurd 10y agoThat's the good part. The bad part is that bunker oil is the opposite of a petroleum distillate. It's what's left over. So it has all the sulfur and other contaminants you want to get rid of for other refinery products. The difference is enormous: hundreds of times the sulfur vs refined fuels, etc.
