I want to make sure I understand this correctly. Russia rammed one of our (USA) drones, forcing it to crash in the Black Sea, with a fighter jet?

FrozenVent posted:Well first your main constraint on how much you can load is in port, because you’re likely to hit the bottom before you finish loading. If the port’s deep enough, the next limitation is the ship’s minimum freeboard, which yeah that’s a reserve buoyancy stability thing. To simplify this, you COULD cut the roof off your car and have a convertible. But it'll never be as good as a purpose built one, and will introduce a whole bunch of other problems to boot, so you are better in every regard to buy something built for that purpose.

The other thing to consider in this conversation is that the size of ships is fundamentally limited by the ability to pass through the Panama Canal/Strait of Hormuz/Suez Canal. Nobody is going to pay millions of dollars for a ship that has to sail all the way to Antarctica and back to deliver a payload, it just doesn’t make sense.

I'm not sure we are near Suez limit and Hormuz isn't really a constraint. Theres plenty of cargo that could go around the Cape without needing the shorter trip, and bigger ships are usually more efficient so that would help save on fuel costs and Suez transit fees. Once speed limits come in it will be interesting to see what happens.

Capesizes hit the Suez Canal draft limit on occasion. Most ships are size limited by other factors long before they hit the canal limits. There’s a reason Handysize is a whole category on the Baltic.

Prius and other hybrids had the petrol engine driving the wheels, not as a stand alone power generator. Nissan is using it to recycle their BEV parts while Mazda is doing it since they really can't re-engineer the mx30 with a more interesting range without pretty much starting back from scratch. Those are both choices done not due to being a sound engineering choice, but as a way to save money. Chevrolet did a mostly petrol-electric layout(but even then the gearbox was linked to use the petrol engine as a drive unit). SlowBloke fucked around with this message at 20:51 on Mar 14, 2023 |

What if flying ships? No canal limits. Some sort of air...ship? Also looking forward to the biofuel reformer fuel cell hybrid cargo ships in this make believe scifi future. Since it's the only way other than nuclear to ever get carbon neutral international shipping.

For the audience confused by the word salad - A bio fuel reformer takes a hydrocarbon and breaks it down into CO and H2, and then following stages turn the CO into CO2. While that hydrocarbon can really be anything one of the best candidates are the ethanols and alcohols produced by fermenting corns and sugars. Ideally the industrial waste sorts. Then a fuel cell turns that directly into electricity. The whole process is about 20% more efficient at electrical production than if you just burnt the source hydrocarbon in an reciprocating or turbine engine. So a ship would use one of those to drive an electric drive train. And fuel cells are expensive, but nearly 100% recyclable, and the cost scales linearly with power output, whereas big engines and turbines get increasingly expensive. Being a bio fuel it *can* be net neutral, unlike fossil sources. International shipping requires the energy density of fossil, or bio fuel, or nuclear, to provide for modern society, and you're not going to reform society to change that.

Also cured pork products have a ton of sodium in them, and (for example) Jimmy Johns bread has a ton of sugar in it. A 16 inch sub there can easily break 2000 calories.

You do you, but going into old age with metabolic syndrome sucks a lot more than without.
