News community around technology, social media platforms, information technology and governmental policy surrounding it.
The core of the story has to be technology focused.
Title format
Post title should mirror the news source title. If you don't like the title of article, look for an alternative source instead of editorializing it.
URL format
Post URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
[Opinion] prefix
Opinion (op-ed) articles must use [Opinion] prefix before the title. Opinion articles refer to articles that their publisher doesn't explictly endorse.
Country prefix
Country prefix can be added to the title with a separator (|, :, etc.) if the news is from a local publisher who doesn't clearly mention the country.
1. English only
Title and associated content has to be in English.
2. Use original link
Post URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
3. Respectful communication
All communication has to be respectful of differing opinions, viewpoints, and experiences.
4. Inclusivity
Everyone is welcome here regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, education, socio-economic status, nationality, personal appearance, race, caste, color, religion, or sexual identity and orientation.
5. Ad hominem attacks
Any kind of personal attacks are expressly forbidden. If you can't argue your position without attacking a person's character, you already lost the argument.
6. Off-topic tangents
Stay on topic. Keep it relevant.
7. Instance rules may apply
If something is not covered by community rules, but are against lemmy.zip instance rules, they will be enforced.

By my estimates solar power would cover 0.3% of its propulsion cost, or 5% of its other electrical needs
Estimating 11000-14000kW needed at the shaft and up to 2000kW for other electrical needs
It reads like there are not that many panels on the ship either.
As is evidenced by their decision to go with dual fuel, the point of the solar was not to cover propulsion costs.
Nor does it even seem to cover a significant portion of auxiliary needs
Except it does.
This power helps run the ship’s operations, lowering fuel use and making the ship more energy efficient.
This is textbook peak shaving. Not to mention the engineering feat of integrating solar with LNG for this cargo application.
Hopping into the comments to decry the ship for not doing full propulsion via solar just shows your ignorance. It's like complaining about a hammer for not being able to screw in a fastener.
It's just greenwashing. Companies do it all the time. Slapp some solar on it or use some insignificant amount of recycling and you got your press release which lazy journalist just have to copy. That lead to clickbait articles.
And if you're being honest you're just defending it because the "by China" in the title.
Accusations of greenwashing are different than accusations of bad engineering. That's a different conversation.
This is an odd strawman to construct
doing full propulsion via solar just shows your ignorance
The only ignorant person here my friend is you, nobody has said or suggested such a thing
Soo, then why did you characterize the solar power as being inadequate for propulsion? That is a meaningless thing to point out - given how the solar is not intended for propulsion. What was your original point?
You sound pretty mad bro
The wattage cannot plausibly be satisfied by those panels. Maritime traffic is ridiculously cheap and environmentally friendly compared to what it does. But it does an enormous thing.
