Why don't we just have one or two very big ships, powered by nuclear reactors. Like, 40-50 kilometers long each, with hydrofoils, top speed just under mach one. Zip around and deliver everyone's shit with big deck-mounted gauss guns that fire packages right to your doorstep as the ship screams past the nearest coastline.
Im gonna need some concept art first. for research puposes
Currently seeking angel investors for 500m buy-in, or I'll take a 200kg of plutonium, if you've got that.
Good god, the stress that would be on the hydrofoil's connecting pieces makes my meager mind whimper.
Honestly this does sound fucking awesome. It could be sold to the ‘murica crowd.
You have me thinking of like.... A ring around the equator with space elevators on it (with stations at the top), and "rail" tracks, with trains traveling between all the stations. Gaussian launchers sending packages to your nearest delivery depot.
Project Atlantis would be an excellent start. Not much in that for Europe though
It's a ring around the Pacific rim, held aloft by centrifugal effects like a whirled billy
I haven't had billy tea in too long

Inaccurate statement.
https://qz.com/2113243/forty-percent-of-all-shipping-cargo-consists-of-fossil-fuels
40% of traffic is for petrochemicals, which according to this article is coal, oil, gas, and things derived from them, which would include fertilizer and plastics and probably some other stuff too like industrial lubricants, asphalt etc. Not just fossil fuels, so not all that 40% would be affected by a switch to renewable energy. It's also worth noting that building out renewable energy generation involves shipping a lot of hardware around the globe as well.
Industrial lubricants and asphalt fit my definition of petrochemicals
But then so do plastics
Also it requires shipping oil to fuel the mining operations needed to produce full scale renewable energy. But if we wait a little bit the quality of power output from the same mining inputs will improve which means renewable later requires less total mining than full scale renewable now, and so you will use less fuel to do that smaller amount of mining.
What people don't realize is that the expense of renewable technology mostly is fuel. Fuel to mine it, fuel to move the raw materials, fuel to refine it, fuel to manufacture it, fuel to ship it to you. The total labor is quite small. So if taken on a specific case the financial perspective alone of a particular application of renewable vs conventional energy the numbers don't add up then likely the renewable is less green. If you wait a little bit for the green cost to come down that indicates improved efficiencies and now it actually is green.
So the answer to make the world more green is not to shift our calculations to spend money on green solutions beyond financial sense. It's to work on technology to lower green costs until it naturally makes sense and thereby also make it more green at the same time.
So if taken on a specific case the financial perspective alone of a particular application of renewable vs conventional energy the numbers don't add up then likely the renewable is less green.
Renewables are more climate efficient and cheaper. Today. All this included. A wind turbine, depending on size, position etc, generates the amount of power used in it's construction within 2.5 - 11 months. Over it's life cycle it generates about 40x the energy you put in. There is no valid excuse to keep burning stuff because it appears cheaper short-term.

Joke's on you when we get even more ships sending the sun and wind around the world, idiot.
Funnily that isn't a bad description of shipping green hydrogen
The delivery mechanism for sunlight keeps burning me while the delivery mechanism for wind keeps knocking things over. Someone help me, I need a lawyer!

Fun vaguely related fact: the 1800s are often hailed as the century of steamships, but in reality steamships had pretty short range and required frequent re-coaling in order to get anywhere and back. The coaling stations around the world were mostly stocked by sailing ships since there was no way to economically transport coal by using vessels that burned coal for their propulsion. So it's more accurate to say that the worldwide transportation revolution of the 1800s was a steam/wind power hybrid.
Oil is used for more than just energy.
Idk why you're being downvoted. Petrochemicals are used for a bunch of stuff, including plastics manufacturing.
We should switch to renewables as quickly and completely as we can, but it wouldn't eliminate 100% of oil use
I mainly agree, but it could be substituted. Various biomolecules are being investigated as a replacement substrate for established (petro)chemical processes. Part of the issue is, that you need to defunctionalise the chemicals which is the opposite of what petrochemistry currently does (which is adding functional groups as needed, not removing them).
This research, however, is stifled by the cheap Price of oil. I know an anecdote of Nivea pulling their funding into a similar project because the price ber barrel recently fell. The project was supposed to last around 5 years.
I argue that if oil wasn't as cheap, ecological alternatives to plastic would have a chance or would be considered at all.
Oil world get either very cheap or very expensive if the petrochemical fuel industry fell over
Very cheap while production was high and stockpiles full, then expensive as major producers left the industry

No, they wouldn't. Capitalism is driven by supply, not demand.
If by some magic we switched to renewables over night, the owner class would open or expand another market to keep those ships moving.
It's both. If demand goes down, price goes down; of supply goes up price goes down.
I expect the supply of shipping is pretty stable. It takes a while for ships to be built, it takes time for them to wear out, so in this case demand would be the driver of short term change, pushing the price of shipping in those ships reduced.
I wonder what could be carried in a former coal carrier.
Yeah, that worked totally well for the Guano and sodium nitrate businesses.
