Everyone is always concerned about scale. But I sometimes wonder if we need to scale down. Are cargo ships full of essential goods or disposable items that will more likely than not enter a landfill without seeing any use at all? We’re really good at over producing items and goods that we don’t need or use. It’s interesting to see businesses try things like this. It might not be efficient or affordable now. But someo…

At end of life, cargo ships are cut up into scrap steel. That scrap is then melted down and re-used to make new steel. I strongly suspect that, if you take into account the energy used to manufacture the ship, sailboats will turn out to have a far higher carbon footprint per ton-mile of shipping than normal cargo ships. Cargo ships, as dirty as they seem on a per-ship basis, are crazy efficient on a per ton-mile basi…

According to [0], a typical container ship generate 12.5 g of CO2 per ton per km, which means that one trip from France to NY with 350T of cargo would release about 35T of CO2 in the atmosphere. I'm convinced that this sail boat generates an order of magnitude less of that (I can't find any estimate of it) Whatever the initial CO2 cost of the construction of this boat is, I'm sure that it's a net benefits if it's use…

Modern container ships are more like 3g per ton (page 5): https://backend.orbit.dtu.dk/ws/portalfiles/portal/158911010... 6000km from France to NY 3g * 6000km * 350tones / 1000 / 1000 = 6.3 metric tones of CO2. I don't know how much disel the sail ship might use, but 6.4 tones of C02 is equivalent of 1974L of disel. According to their own website https://graindesail-logistics.com/en/ they aim for 1.8 g off CO2 per km…

Well we have juice boxes for that now. Krakens are still a problem though.

Ha! I can see a kid's commercial for a juice box with pirates sipping on a juice box while sword fighting a Kraken attacking their ship.
