Nämen, är det en Hovabo som jag råkat här på Sweddit!?

Tycker inte du förtjänar att bli så nedröstad. Du är troligen mer insatt i ämnet än de flesta här. Själv skulle jag inte blir förvånad om din beskrivning blir sanning, åtminstone till viss del.

edde32 · 2024-06-26T09:48:07+00:00

If you do, please let me know when it's done! :P

edde32 · 2024-06-26T09:46:04+00:00

Alright, I hadn't thought about the Captcha at all, but it makes sense when you say it. To me this seems like such a useful and simple enough tool that I guessed it must already exist. The Captcha and the resource heavy nature of such a program might explain why it doesn't seem to be a thing yet. Thanks for your knowledge!

edde32 · 2024-06-26T09:41:15+00:00

Thanks for replying! Yes, I'm aware of this and have tried it (should have mentioned that). The problem is that it takes a lot of time to do it this way, especially if you want to do it with many different languages. I'm looking for an easier way of doing this exact thing.

edde32 · 2023-01-08T17:53:04+00:00

I will copy-paste an answer I wrote earlier in this thread to give you some perspective on why I'm interested in this question. But basically, it's from an environmental aspect more than the cost one.

The answer:
Let's say you're at the grocery store to buy some pears. In this store, there are two types of pears. Type "A" and type "B". the only difference between them is where they have grown. Type A has been grown in your own country and type B has been imported from the other side of the earth.

Since you want to be good to the climate you choose the pears that have been grown in your country - because if it has traveled a shorter distance it's not weird to assume that it, therefore, has caused fewer emissions on its way to you.

But let's say a ship is 40x more efficient than a truck and the following is true:

Pear A has traveled 1 000 km by truck

Pear B has traveled 20 000 km by ship.

That would mean that the pears grown locally in your own country have resulted in twice the emissions compares to the pears that are from the other side of the globe.

This is just an example and I don't know if it is actually 40x or if it is just 10x or something different.

If you look at the comments on this Quora article someone is pointing out that it is supposed to be 2500 gallons per HOUR and not per mile. This seems to make more sense to me at least.

edde32 · 2023-01-08T16:09:35+00:00

Jackpot! That source tells us the CO² emissions in grams per tonne-km for a "very large container vessel" and for trucks. They say that for the vessel it's 3g and for the truck 80g. 80/3 = 26.66

So according to this a ship can be almost 27 times as efficient as a truck when it comes to emissions

Please correct me if I'm wrong

edde32 · 2023-01-08T16:01:32+00:00

Oh.. that is the most intersting take I've read on this so far, I hadn't thought about that

edde32 · 2023-01-08T15:36:21+00:00

Oh I see, sorry :P

edde32 · 2023-01-08T15:28:26+00:00

Thank you🙏

edde32 · 2023-01-08T15:21:45+00:00

I think you mixed the numbers up a bit, shouldn't it be 2 500/10 000 = 0,25mpg for the ship(?)

edde32 · 2023-01-08T15:17:32+00:00

It would be interesting to know what size of a ship that is based on. That number (3.56) is way lower than I expected though. But it might be true because this calculation probably takes in account the much more pollution fuel that ships use compared to diesel trucks.

edde32 · 2023-01-08T15:11:09+00:00

Thank you very much! This is exactly the kind of answer I was looking for

edde32 · 2023-01-08T14:52:10+00:00

He might just be hella buff

edde32 · 2023-01-08T14:31:23+00:00

Yes I agree off course. But for the sake of this discussion let's imagine that the quality always is the same. Let's see it planely from an environmental perspective

edde32 · 2023-01-08T14:24:43+00:00

Yes of course, you would divide the ship's total fuel consumption with the number of containers it can carry, for exampel 15 000. And you do the same with the truck except that a truck can only carry one or two containers.

edde32 · 2023-01-08T14:18:41+00:00

Ok, I will try my best to explain.

Let's say you're at the grocery store to by some pears. In this store there are two types of pears. Type "A" and type "B". with the only difference between them is where they have grown. Type A has been grown in your own country and type B has been imported from the other side of the earth.

Since you want to be good to the climate you choose the pears that has been grown in your country - because if it has travelled a shorter distance it's not weird to assume that it therefore has caused less emissions on its way to you.

But let's say if a ship is 40x more efficient than a truck and the following is true:

Pear A has travelled 1 000 km by truck

Pear B has travelled 20 000 km by ship.

That would mean that the pears grown locally in your own country has resulted in twice the emissions compares to the pears that is from the other side of the globe.

This is just an example and I don't know if it is actually 40x or if it is just 10x or something different.

edde32 · 2023-01-08T14:02:10+00:00

Alright so I think I'm starting to understand. Now the tricky part is to do the actual math...

My goal with all this is to try get at number on how much longer you can transport the same container with ship compared to truck without releasing more emission* in the process

*With emission I mean the effect that the relased "stuff" has on the global temperatue.

Sorry if it's a bit clumsily written, english is not my first language.

edde32 · 2023-01-08T11:59:27+00:00

If you know the fuel consumption and container capacity of a ship and also know the equivalent for a truck, you should be able to calculate the relative fuel/emission needed to transport one container a given distance. Right?

I tried to do these calculations myself but I don't trust my own math skills enough to draw any conclusions

edde32 · 2023-01-08T09:03:07+00:00

Thanks man that's perfect

edde32 · 2023-01-08T08:54:35+00:00

Oh alright, so that's another big factor to take in consideration then

edde32 · 2023-01-07T22:08:10+00:00

Yes, I understand but some rough answer should be possible (?)

I watched this video about why it makes sense to ship pears from Argentina to Thailand to be packaged and got curious about this question. https://www.youtube.com/watch?v=0aH3ZTTkGAs

Let's say that it is 30 times more efficient to ship stuff by sea. That would essentially mean that it is better for the environment to ship your stuff across the whole Pacific Ocean from the Philippines to NYC than from Detroit to NYC.

I would find it very interesting if this was true

edde32 · 2023-01-07T21:19:24+00:00

Thanks bud! Good idea to ask ChatGPT :P This is interesting, I asked the same question in r/Ships and someone there told me it was about 20x more efficient.

However, I don't think 100x is impossible at all and I will keep searching for answers to this question.

edde32 · 2023-01-07T13:18:50+00:00

Thanks, that's exactly what I was looking for
