Why would LED ligths in cargo ship is a good idea and not spend much fuel?
ANSWER:
LED lights are a good idea for cargo ships because they are highly energy-efficient and long-lasting compared to traditional lighting systems. LED lights consume much less energy to produce the same amount of light, which translates to a reduction in the amount of fuel needed to generate the electricity to power them. In addition, they have a much longer lifespan compared to traditional lighting systems, reducing the frequency of replacements and maintenance.
By using LED lights to promote the growth of kelp in the ocean, cargo ships can reduce the need to use fertilizers and other harmful chemicals, which can be detrimental to marine life. Furthermore, kelp can help sequester carbon dioxide, potentially mitigating the effects of climate change. Overall, using LED lights is a more sustainable and environmentally friendly approach to promoting kelp growth in the ocean.
How many lux is 1 million bright white LED lights?
The brightness of a single LED light can vary, so it is difficult to provide an exact answer. However, on average, a single LED can produce about 1 to 10 lumens of light.
Assuming an average LED brightness of 5 lumens, 1 million bright white LED lights would produce about 5 million lumens. To determine the lux level, you would need to know the area over which the light is being spread. For example, if the 5 million lumens were spread over an area of 100 square meters, the lux level would be 50,000 lux (5 million lumens / 100 square meters).

Well there's a fair bit of BS if ever I heard it.
Which part of a cargo ship is continuously lighted? Why make life easier for the rats?
Does anyone actually want kelp (or anything else) to grow on the hull of a ship?
Fail.
-
Possibly Translation Errors.
The first paragraph is Fine.
But Cargo ships, kelp, fertilizers & harmful chemicals does Not add up.
Perhaps, it's Not about Cargo Ships.
Cos it Doesn't state Red or Green lights.
Or
It Ain't bout Kelp underwater in the Ocean, coz it mentions White light.
If Cgpt is at play here is also Doubtful.
(Thou, No doubts bout it All being Unsolicited.)
-
And AFAIK practically all navigation lights are LEDs nowadays anyway. Not that power consumption is a major concern on a cargo ship, but reliability certainly is.

I do not believe this is a commercial site, I have checked to the best of my ability. If it is it is not very apparent or accessible. It is a genuine academic site I believe.

Good advice! Pity the commercial "let us write your thesis" spammers haven't read it.
I'm less in favor of the passive voice. Say why you did it, say what you did, say what you saw, say what you think about it. It's the standard debrief for things that really matter, and science really matters.

Chat gpt is angling for a 3rd class if not a fail, even if it includes new research. Waffling on like that is severely marked.

Today I heard a story about someone who became an editor at a major newspaper, just 2 years after graduation...
- She was editor of AI
- It turns out that the AI was writing the news stories, and her editors job was to detect and correct (or delete) the AI hallucinations...
The story is here: https://www.scientificamerican.com/podcast/episode/if-ai-starts-making-music-on-its-own-what-happens-to-musicians/#transcripts-body
-
The answer is simple. Music is made by animals, for communication. Noise is made by machines, because there's something wrong.
-
I know nothing about ChatGPT and will probably never use it. Completely off-topic, what would happen if one asked "what is ChatGPT?". Would it go into a terminal loop and self destruct?
-
ChatGPT is a system for cutting and pasting superficially relevant text published on the internet.Thank you for your enquiry. We look forward to wasting more of your time in future.
-
That's boring, but thank you, Alancalverd. When bored mischievous thoughts invade my psyche.
-
"Boring is the activity of making holes in things. Large vertical holes are known as shafts. Shafts are also rigid poles. Poles are people who live in or originate from Poland, a central European country with a strong tradition of craftsmanship in wood. Polish carpenters can be amusing but are often boring at work. Boring is the activity of making holes in things....."
-
Yes indeed, Alancalverd, these carpenters that you so eloquently refer to will burnish their work with a generous layer of polish.

Hi.
There doesn't seem to be any further comments from the OP (remotemass), I'm not sure what the original question or issue was supposed to be.
Nevermind, let's just look on one thing. ChatGPT can answer some questions without a user needing to use a forum. "Why is the sky blue?", "Why do dogs have tails?" - various small questions that people may have otherwise put on a science forum like this one. It will actually give good answers to sensible short questions like that. So that's most of the main sections of the forum sorted out.
Also, there's no need for people to spend some hours creating a new theory to post in the new theories section. ChatGPT can easily produce a 1000 word essay (or more) on just about anything: "Write 1000 words describing a new theory of gravity which contains the phrase 'quantum hyper loop' ". Best of all, the replies can be generated by someone copy-and-pasting the article straight back into ChatGPT and just asking it to critically review that text.
So, it's not all bad: ChatGPT is capable of making forum users (including moderators) completely obsolete.
Just for demonstration I have fed ChatGPT with this instruction....
"Please critically review the following article: " (and then copy-and-pasted the recent thread located here:
https://www.thenakedscientists.com/forum/index.php?topic=86209.0 ).
The reply has been copied to that thread - I've specifically marked where ChatGPT took over, you could easily imagine that this could have been the only reply required. I have spent some time to write my own reply first just because it seems rude to leave the original creator of that thread with nothing but an automated response.
Best Wishes.

I don't think a mod's job is to review but to moderate - we are referees, not sports journalists.
As for general involvement in a thread, it would be interesting to see if ChatGPT could contribute something novel or amusing.

Hi.
As for general involvement in a thread, it would be interesting to see if ChatGPT could contribute something novel or amusing.
As for something novel, what are you talking about?
1. The entirety of the original post in this thread was generated by ChatGPT. People have managed, or wished to talk about it. Remotemass has posted at least one other thread that contained nothing other than some output from ChatGPT.
2. It's been the main topic of discussion in a thread by @hamdani yusuf for the last week or two (See https://www.thenakedscientists.com/forum/index.php?topic=77747.msg699873#msg699873 for example).
3. @tonylang submitted a lengthy (approximately 3 page) forum post that contained only a structured discussion with ChatGPT and nothing else. (reference: https://www.thenakedscientists.com/forum/index.php?topic=54557.msg698234#msg698234 ).
4. I have just used it to analyse and report on a draft paper submitted in the new theories section of the forum.
5. If you want something amusing (and relevant) just ask....
[ Invalid Attachment ]
6. Other forums are already considering what sort of policies they will have for the use of ChatGPT and similar software. For example, deciding if content generated by ChatGPT must be cited and acknowledged similar to taking an extract from some other text or if it is acceptable to consider it as part of your own work (just using some sophisticated tools).
- - - - - - - - - - - - -
Anyway, that's enough about ChatGPT, I'm not their PR representative. Quite the contrary, I'm just a human being who doesn't want to be answering or replying to forum posts that no human being ever created in the first place. However, I'm also just about calm enough to recognise that this sort of software is an incredibly powerful tool when used appropriately. One way or another, it is already out there and having some impact on forums including this one.
Best Wishes.

ChatGPT can only source its data from the internet, therefore none of its source material can be considered novel or original. At best, it's stuff that you might have found if you had the time and inclination to search everyone else's published material, but that is about as interesting and valuable an intellectual exercise as literary criticism - "books of bad English written about a few pages of good English".

Hi.
ChatGPT can only source its data from the internet, therefore none of its source material can be considered novel or original.
The G in ChatGPT stands for "Generative". It doesn't just copy huge sections of existing text, it is capable of blending many texts and, more importantly, generating completely new text just by following some basic rules of grammar that it has identified automatically during its training and development.
What definition of "new" or "novel" are you trying to apply? Nothing I can create is really novel. All the words I know were learnt from my parents, from school or from other pieces of text I read in later life. Eventually I remembered the spelling, how the word was used and what meaning was being conveyed by it. All I do is to put those words down in some order, following some rules of grammar.
The whole phenomena is more easily seen (or heard) when AI systems OR human beings are asked to compose music. There are only so many notes that exist on a treble clef and both human and AI composers will inevitably have some musical phrases that are identical to sections that exist in some other piece of work. However, overall the piece of music can be considered as something new and original. Both the AI and human being were influenced by music they have already heard. Both of them used some sections that were just minor variations or completely identical to something they have heard. Both of them blended existing ideas together in a certain way and finally, both of them made some sections that were genuinely quite new and just followed some rules or principles for setting down a combination of notes that would sound sensible.
@evan_au, post #7, gave some examples of how creative an AI system can be.

Let's also return to the earlier parts of this forum thread for a moment. Many people were quick to dismiss the replies from ChatGPT about LED lights but it was probably just having some trouble understanding the task. Like all software, the user is an important part of the system. Let's just change some spelling and reformulate the question.
[ Invalid Attachment ]
That seems like useable output to me.
Now let's interact and prompt it on the issue of growing kelp:
[ Invalid Attachment ]
That also seems like useable output. The final phrase - about damaging the ecosystem - seems to be a very good example of an interesting, relevant and totally new issue that ChatGPT has brought to the table.

I can't imagine that the reliability or power consumption of LEDs is news to anyone with an interest in lighting, particularly in a commercial or industrial context.
Obviously, the most intense light will be on and around the LEDs, on the ship and wherever it moves slowest or stops. The last thing any shipowner, harbormaster or seaway maintenance dredger wants to do is encourage the growth of kelp, barnacles, or anything else. It won't have any effect on the high seas because kelp and other seaweeds can only inhabit shallow water.
So what "useable output" has AI contributed?
1. Common knowledge. If you are building or refitting a ship, lighting manufacturers will offer you catalogs of LED lamps and help you choose the most appropriate ones.
2 At worst, a danger to shipping, and at best, a serious increase in hull drag that will require additional fuel consumption and maintenance and thus damage both trade and the ecosystem.
Music is one of the ways animals communicate with each other. If I'm playing hymns in a brass band, I'm communicating someone else's superstitions to other believers (I don't share the superstitions, but the postman isn't the taxman - he's just carrying the message). If I'm playing jazz, I'm telling the audience how I feel. I have no interest in the noises a machine makes - the less the better, unless something needs repairing.

LED lights in cargo ship
It's already being done - cruise liners are lit up at night like a beacon on the sea.
- Partly so every other ship can see them from a great distance (even without radar)
- Partly for advertising
- Partly so they can see anyone toppling overboard
A month ago I was talking to an astronomer who had been the resident expert on astronomy-themed cruises
- She described the feeling of power as she called up the bridge, and half the ship was plunged into darkness.
-
And if you are crewing any vessel without inebriated passengers, from a small yacht via military vessels to a tanker or container carrier, the last thing you want is to be lit up like a christmas tree. Nav lights and only the deck lights you actually need for work, please. Radar is all very well, but scotoptic vision works at all ranges and every crew member can use it - as long as the ship is dark!
An old chum was the navigator on a bulk carrier. Only used GPS to confirm his astronomical sightings, because one day, the electronics will fail but the stars and his mechanical watch will still be going round.

Cgpt is Good, but it can do Better!
LEDs are Nice, having more will be Nicer.
Kelp is a bit Complicated.
I donno if We have figured out Kelp varieties that could grow in Deep oceans vs Shallow coastal shorelines.
Temperature differences across Oceans would also need to be Considered, taking into Account Sunlight variations at the Equator vs the Poles.
Not sure if Kelp would like it's Circadian Rhythm being Disturbed in an Untimely manner by Huge cargo ships.
Donno how long Ships would have to be Anchored to provide enough Blue light stimulation, don't think Them passing by slowly would be Appreciated by the Kelp or not.
Anyways, Hope We can come up with a tasty n delicious variety of Kelp, fit for human Consumption, Without Any long term Negative side effects.
(Not an ADboy but still, Thank You Google Search, Wikipedia & a peanut sized human brain)
*Suggestions :-
The OP seems to be Advertising or Promoting use of a Specific LLM.
It is Observably becoming a Repeating & Regular trend.
Responding to a Query with Generative textual output program, is Fine.
But, it should Not be done Unless & Until someone Specifically asks or Requests for it.
Besides, after acquiring a Logical output, Purposefully Editing it, or attempting to MisTranslate it & then Copying & Pasting it on a Public Forum could be viewed as a Means towards Tarnishing the image of a Specific LLM or Company.
(OpenAI will Definitely Not like this & Cgpt Admirers will Hate it)
*Note - Creating an OP byself, invoking Cgpt byself & providing an Answer for the same byself...UnSolicitedly is Spam!

Starting around 2001, the compound semiconductor gallium nitride fomented a revolution in lighting that has been, by some measures, the fastest technology shift in human history. In just two decades, the share of the global lighting market held by gallium-nitride-based light-emitting diodes has gone from zero to more than 50 percent
See: https://spectrum.ieee.org/silicon-carbide
Many ships are switching to electric motors, and these semiconductor compounds make the conversion and transport of energy more efficient within the ship. (For now, ships will remain with fossil fuel storage.)
-
I donno if We have figured out Kelp varieties that could grow in Deep oceans vs Shallow coastal shorelines.
Obviously not. Kelp relies on photosynthesis. No sunlight at depth. If the sun went out and the only source of light was LEDs on ships, the only place kelp would grow would be on the bottom of ships and in the shallow shipping lanes and harbors, exactly where you don't want it.
What AI has contributed to this discussion is Artificial Stupidity, which now seems to have infected some humans.

The key to GPS reliability is multiple obsolesance. GPS has more than 1 satellite there is more that 1 positioning system. Have more than 1 receiver, one powersource you should be OK. They use this thinking on aircraft.
-

Yes, it sometimes feels that way.
They use this thinking on aircraft.
.....and still it fails! I've had 3 dual-system fails to date on final approach, I've lost count of the en-route dropouts, and almost every day there are published NOTAMS of local blackouts and jamming exercises.
AFAIK the stars have been in pretty much the same position for a few billion years and compass variations are plotted on navigational charts. The advantage of a plane is that you can fly above the clouds to see the stars, and you can (eventually) stop or slow down a ship.
The story goes that sun sights were invented by an American captain who, rather than run aground, hove to in the Bristol Channel for two days in fog until he could see something, and the only something was a brief glimpse of the sun. Not sure what he was carrying, but presumably we must apologise for using sextants if he was a slave trader.

The best definition I know of intelligence is "the ability to surprise".
Well ChatGPT has certainly come up with a surprisingly stupid suggestion here, but that doesn't justify its use or existence.
-
AFAIK the stars have been in pretty much the same position for a few billion years
A slight exaggeration there.
Edmund Halley, studying an ancient star chart noticed that some bright stars were out of position by about half a degree (the width of the full Moon).
- No self-respecting astronomer would make a mistake like this
- We now know that these stars are bright because they are fairly close to the Sun
- And because they are close, they tend to move across the sky fairly quickly - so called "Proper Motion"
https://en.wikipedia.org/wiki/Proper_motion#History
The Gaia spacecraft is measuring the proper motion of stars with extreme accuracy, and has detected streams of stars that are connected by their similar trajectory, and are probably remnants of small galaxies swallowed by the Milky Way.

Asking a 10 year old kid "Why would LED ligths in cargo ship is a good idea?" would be interesting that it would give you an insight into the child's worldview.
But it wouldn't tell you much about ship lighting.
The same is pretty much true of asking a chatbot.

Note the qualifying "pretty much". As far as terrestrial navigation is concerned, any journey lasting less than a human lifetime can be adequately navigated by looking upwards at night.
