Because if it’s a closed loop then the heat doesn’t leave the system so at some point you need to open the system. Your options for getting heat to actually leave the system are: evaporate water, air coolers (not efficient with large systems or in warm climate), or water coolers.

The water coolers sound good but then you are heating up a local water supply which can kill a bunch of local wildlife

They have 0.2T in assets the world has around 660T in assets which as I said before is a tiny fraction. Obviously both hold a lot of assets that aren’t worthwhile to AI training such as theme parks but when you consider a single movie that might be worth millions or billions has the same benefit for AI training as another movie worth thousands. the amount of assets Disney owned is not nearly as relevant as you are making it out to be
⁨Comment⁩ on ⁨AI industry horrified to face largest copyright class action ever certified⁩ ⁨⁨5⁩ ⁨days⁩ ago⁩:
It’s not because they would only train on things they own which is an absolute tiny fraction of everything that everyone owns. It’s like complaining that a rich person gets to enjoy their lavish estate when the alternative is they get to use everybody’s home in the world.

But the problem is you don’t have anything to tie that to. if you have a car that gets 4 gph but goes 100 mph then it’s more efficient than a car that gets 3 gph but only goes 50mph but even with those you miss out on the actual efficiency which for a car is usually transporting people.

So if car A gets 4 gph at 100 mph and transports 2 people it gets 50 passenger miles per gallon of gas which is finally an actually useful metric

For LLMs that becomes much harder to quantify but a useful metric might be wh per minute of time saved or mL of water per minute of time saved. Unfortunately to quantify those you would need to do much more in depth analysis and probably also factor in false readings and time lost from that

Your units don’t make sense. Watts shouldn’t be used for a fixed energy usage it’s like saying a car drove across the U.S. and it did it at 4 gallons per hour.

The more useful metric to use is Gwh so chatgpt3 used 1.3 Gwh which isn’t bad but gpt4 used 62.3 Gwh in training plus an extra 1 Gwh per day

It took 60m years for fungi to evolve to break down lignin (trees) and the eventual oxidation of the lignin decay products has caused the most rapid climate shift we have ever seen
⁨Comment⁩ on ⁨⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
I didn’t try actually contacting customer service about it but from talking to other people it has to do with how the watch moves around during exercise that gives the false readings. If I just sit still and compare to a pulse oximeter it stays pretty close but if I am biking or walking around the values change drastically. Then for some reason while when I sit down or lay in bed my heart rate is around 65 it says my resting heart rate is in the 50s
⁨Comment⁩ on ⁨⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
As a current Garmin user I really like a lot of the features of the Garmin but the app for smart watch health tracking is atrocious and some of the values you get are clearly wrong like it recording my resting heart rate at 15 bps lower than it actually is.

The battery life is still insane which makes things like sleep tracking really nice
⁨Comment⁩ on ⁨⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
Some do, but the limitations of usb C (or any physical plug) are present and while it sounds nice in principle to have all the devices use the same cord it’s in general not worth the sacrifices that others have mentioned like it taking up extra room and the increased likelihood of water/sweat/particulate ingress
⁨Comment⁩ on ⁨Why are there no universities/colleges that start in the afternoons?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
My engineering classes had one time option a year (not just per semester but only offered once a year) and none of them were offered later than 2pm
⁨Comment⁩ on ⁨Why are there no universities/colleges that start in the afternoons?⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
High schools run early because one of their primary functions is childcare while parents work and parents commonly leave for work between 7-8 so kids need to be on the bus before then. They then stagger primary, middle, and high school so they can use the same bus drivers for all of them and high schoolers leave first so that they can arrive home first without parents. This is being changed as high schoolers need more sleep but it’s not for sports.

In college you need professors to teach classes and most of them want to work a more traditional schedule so want to be there from 7-3
⁨Comment⁩ on ⁨Can somebody please explain why the world hasn't gone nuclear yet?⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:
The U.S. has an increase in energy demand, and if we consider phasing out fossil fuels then the demand for new power plants is huge.

Arkansas nuclear one which started construction in 1968 and finished in 1974 had a total construction cost of 2.522B (2007 dollars) and produces 13555 GWh a year with a 66 year license giving it a $2.81//MWh in general initial construction represents 60-80% of total nuclear power costs so if we use the conservative value that’s still under $5/MWh using 2007 dollars and if we scale to today that’s $8/MWh. So not sure what you mean by it didn’t drop costs.

It was expensive compared to fossil fuels that had little to no safety systems
⁨Comment⁩ on ⁨Can somebody please explain why the world hasn't gone nuclear yet?⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:
France actually also has had cost overuns and projects extended as well. The biggest problem hurting nuclear is we do each project as a one off design which increases the cost and time immensely. Solar had gotten much cheaper and able to be installed quickly largely because of manufacturing standards and continued development which encourages companies to develop specialized equipment, construction teams to be familiar with standards, and costs to be lowered due to mass production.

That’s why I mentioned the NOAK study on nuclear power which shows a lifecycle cost of 66/MWh compared to solar plus storage which even with only 17 hours of storage is sitting at $104/MWh then if you factor in the additional losses from transmission, cost of installing UHV transmission lines, and trying to use solar to power places that end up with high energy costs for heating at night and 24hr manufacturing, solar doesn’t make as much sense.

Vogtle is everyone’s example of why nuclear power is bad in the U.S. but it was also the exact lesson on why nuclear power can work as the cost overruns had to do with their original contractor filing for bankruptcy, having to return 3 core baskets because they didn’t have a reliable manufacturer, and the fact that they had to come up with the R&D cost for 2 nuclear reactor designs. Now that the project is complete though the AP1000 is approved to be built so designs costs will be a fraction, numerous designs are being built around the world so manufacturers should be able to handle the project parts, and we have construction crews who have built the exact reactor before

As I said before solar and wind should defenitely be considered before nuclear but nuclear can still be a viable option
⁨Comment⁩ on ⁨Can somebody please explain why the world hasn't gone nuclear yet?⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:
There are still losses in those lines that can be around 10%, high voltage transmission lines use a lot of copper and can have high cost, they can be a point of failure, they can start forest fires, and if we actually build full scale nuclear system their price will drop down extensively. An MIT study estimated $66/MWh is achievable with a full build out which is already cheaper than solar plus storage, So when you factor in the additional cost of transmission lines nuclear just makes more sense.

But for places like LA that see huge electricity transients during the day as peak sun correlates to peak AC nothing is better than solar and while I haven’t done extensive research on off shore wind everything I have heard about it is incredible where it works.

Nuclear is for places like Seattle that for large chunks of the year gets negligible sun so the amount of storage you need to maintain full power is impracticable and the losses for sending electricity there from sunny places is unsustainable

I definitely don’t think nuclear should be our first or even second choice but it should be an option that fits its niche because our number one priority needs to be reducing our fossil fuel usage and wasting a bunch of material in places that aren’t a good fit is irresponsible
⁨Comment⁩ on ⁨Can somebody please explain why the world hasn't gone nuclear yet?⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:
Renewables get cheaper because we are building them… if we built nuclear at the same frequency as renewables their price would plummet as well.

Personally see the best option as a combination, in places like LA, Las Vegas, Phoenix solar should be the number 1 power source. Build wind power in places like Wyoming, and off shore wind where it’s possible. But when you have a place that needs huge amounts of batteries to try and compensate for inconsistent wind/solar that’s where you should build nuclear.

Nuclear is not renewable and has a lot of issues but we also shouldn’t ignore the negatives of lithium, nickel, cadmium, and cobalt mining. At the end of the day all of them are better than fossil fuels

It is also a very large data set it has to go through the average English speaker knows 40kish words and it has to pull from a large data set and attempt to predict what’s the most likely word to come next and do that a hundred or so times per response. Then most people want the result in a very short period of time and with very high accuracy (smaller tolerances on the convergence and divergence criteria) so sure there is some hardware optimization that can be done but it will always be at least somewhat taxing.

Yes a single blip where there was a 1% decrease in beef without a corresponding drop in GhG that in that same year they had a bunch of cows that were grown to maturity and then slaughtered.

I went a step further though I downloaded the CSV files and ran a correlation on them using excels CORREL function and they had a 0.98911 correlation

So ignoring the fact that English speaking is still not part of eugenics, do you think the only way it can be non eugenics based is if they shared those same sentiments to every country in every language in equal proportion? Or how else could they share the belief that having children is bad for the planet without it being eugenics based on your opinion?

So you are comparing a single year which had a 1% decrease in global beef consumption (1995 to 1996) and using that information to claim that beef doesn’t cause ghg?

What was the reduction in beef consumption world wide compared to the reduction in ghg?

That is the classic problem of a correlation. If you are sitting in a room that is warm and you notice that when you are using your laptop the room is slightly warmer and when your laptop is off the room is slightly cooler would you say that the driving force for the temperature of the room is your laptop? Or could it also be the oven, the outside temperature, the heating/air conditioning, the number of people in the room, etc. we do have enough evidence that global air travel is a significant contributor to ghg and therefore climate change but it’s estimated to be 2.5% compared to agriculture which is 10%

It’s a manner of perspective, Coca Cola is considered one of the largest polluters on the planet but that’s not because corporate Coca Cola is out there polluting for funsies it’s because they make a product that individuals purchase and then individuals improperly dispose of. Sure no one person can stop Coca Cola from polluting but isn’t the pollution caused by your individual purchase your own responsibility?

Are you comparing that to a time that everyone stopped eating beef or how are you using that information to make the claim that meat isn’t the problem?

How is it eugenics if it has nothing to do with a parent’s genetic make up? Like if they said “meat eaters shouldn’t have kids” you could try and make an argument for eugenics but for nobody to have a kid or for everyone equally to have less children how is that eugenics?
