The power of 21000 homes for advertising.
What’s most impressive is that it is even legal.
Advertising? This thing is essentially a theater. Yeah, it can run advertisement but anything with a screen can do that. It’s like saying a movie theatre is for advertising.
It’s a 400 foot tall screen that’s constantly on and in view, even at night, which plays ads like 90% of the time. Calling it “essentially a theatre” is a huge understatement.
But the energy usage is quoted as peak for the entire venue - which is literally a theater / concert hall. It opened with a live U2 performance. The energy usage isn’t just for the displays, it includes all the power for the entire building, the concert speakers, heating/cooling, indoor lighting, any kitchen equipment, etc.
Currently, an agreement is under review to ensure that 70% of the Sphere’s power needs will come from solar sources, with the other 30% from non-renewable energy that will be offset by renewable energy credits.
Ahh yes, energy credits. AKA bullshit.
We shouldnt call them energy credits, but rather indulgences.
We should call them FRAUD
Somewhere in an ancient crypt, the bones of Luther begin to twitch to life…
Hey!
They’re not always BS. Just most of the time!
Or are they? Some of the companies who are the best at it and seem to be genuinely trying have been shown not to be able to guarantee one way or the other.
“Wait, someone cut down that forest we planted?!” (no joke)
Edit: see REC clarification below (thanks!)
Just to be clear, renewable energy credits are different than carbon offsets, and easier to guarantee because they’re often tied directly to a metered renewable energy source.
That said, there are still junk RECs on the market, like those tied to energy that was produced up to 2 decades ago that nobody got around to claiming / retiring. Or RECs tied to energy sources that may have happened regardless of the REC sale.
Ohhh good point! Wanted to edit that into my comment there even, thank you.
The junk RE credits are really interesting. As is the “ha we were building that solar farm no matter what!” problem - reminds me of when that happens in… tax deductions I think.
At least I understand forests that are replanted over and over to be used for lumber, effectively reducing the use of old lumber for myriad products.
Energy credits — what a bunch of vacuous rhetoric.
The reality is that it’s energy being taken away from the overall grid, requiring a larger grid and thus prolonging our dependence on non renewable energy while we build up renewable sources.
If we weren’t so wasteful with our energy we wouldn’t need as much of it and it’d be easier to go fully renewable.
Well this is not good math at all. If you create a project and offset all its power requirements, you haven’t added anything to the grid. The alternative is to not do stuff, which is not going to happen anytime soon*, so it’s a net good thing and needs to be incentivized, not disparaged.
*Well it will happen after the water wars and plagues wipe us out, and the sphere will stop drawing any energy at that point.
Consider ”hate credits”… like imagine the KKK can do whatever it wants so long as they claim to offset it with “hate credits”…

Nevada has pledged to achieve net zero emissions of greenhouse gases by 2050, and the solar project under construction to help offset its energy debt is estimated to complete in 2027.
How stupid is it that somebody can claim “Net Zero” greenhouse gas emissions when 30% of their power is greenhouse gas.
Just gonna throw this out there. Fuck credits, charge a carbon tax.
We’ll also ignore the fact that that solar could have been used to offset actual needs instead of this BS.
If only Las Vegas were located somewhere that the sun shines almost all day every day. \s
I highly doubt the operating hours of this ball of decadence match the time when solar power peaks
If only the creators of the ball had enough profit coming in to put up more solar panels and build up a battery bank for the night so they wouldn’t take anything from the grid…
And yet they still couldn’t cover the last 30%.
That’s probably at night
Regardless, that energy could be going to offset other energy currently being produced by non-renewables no matter which way you slice it.
Vegas exists because of the BS.
The word net does a lot of heavy lifting and it’s just a scam
You can use 100% coal power and claim net zero by buying a forest
Well you don’t understand what “net” means.
It doesn’t mean literally zero. It means colunm A and column B average out to zero.
To acheive a real net zero, they have to save energy somewhere else that takes that column past 100% (Such as if their solar panels produce more energy than they use during certain times.)
They probably just make some shit up to say their are saving extra somewhere they aren’t (so to that point, yes…credits are bullshit.)
Maybe, I mean just maybe, they can run this thing only as long as the solar generated power lasts, and then turn it off 30% of the time.
Run it at 70% percent brightness.
Oooh, this is a good idea
Fuck credits, charge a carbon tax.
IMO it seems RECs are a better solution than carbon taxes at least in situations like this. With RECs you’re buying renewable energy to offset non-renewables, with a carbon tax the company is just giving the government money for use of non-renewables. Only funds spent on RECs in this case actually go to supporting the renewable energy sector. I’m no expert in this stuff so I could be off, just how I understand it.
They never claimed net zero. They plan to achieve net zero by 2050
Yeah, that’s in the quote. I’m more complaining about the concept of “net zero”.
Exactly. Carbon credits for the win! I love me some Pigouvian taxes. :)
Las Vegas in general is a testament to the hubris of humanity and an admittedly impressive technical feat. Does it even exist without the Hoover Dam?
I don’t know about power, but Vegas is actually incredibly water efficient. Due to the way the water rights work with the Colorado river, they’re not allowed very much, but it doesn’t “count” if you put it back in. So nearly every drop they use is treated and put back (probably cleaner, tbh). Boggles the brain, but somehow it’s actually a fairly sustainable city. More than any other other major metro, in any event.
Considering they are in a literal desert, they would have to be fairly sustainable to exist in the first place. Not saying it’s not super impressive, my dad lived out there when they were building up a lot of the expanded infrastructure and he has some cool stories about how he saw the desert on the outskirts disappear as they added in all the water and transportation stuff
What do other cities do with their wastewater? Isnt that the norm?
Thrilled you asked! So yes: Treatment is always required, but the final destination of the treated water can vary. For instance, in a lot of places they may have municipal water TO a home or business, but that may be discharged to septic, as opposed to the river. Also in a lot of areas, water may be taken out of an underground aquifer (either by private well or a municipality) but when treated it may be discharged into a river or ocean. That can create problems because if you’re near the coast, the empty space in the aquifer may be filled by salt/brackish water that can lead to salinity rises in the aquifer. To solve that some places turn to “ground water recharge”, which is just a fancy way of saying “we built a big well to put it back in the aquifer”.
Increasingly, you’re seeing some places essentially sell their treated water. Santa Rosa CA, for instance, built an entire pipeline that goes from their treatment facility to another municipality to be injected into their groundwater.
So yes, everywhere treats it, but the final destination makes a difference. Las Vegas (or anyone else on the river) only gets credit for what goes back into the river, so any evaporation etc is a problem. It sounds trivial, but there is a reason those other strategies exist. It essentially doubles every pipe, limits where you can park a treatment plant etc. Vegas also does some great grey water re-use. That essentially means it doesn’t go “back” but can get used many many times, limiting the initial draw.
Wastewater is funny because it’s far from rocket science, but the numbers to implement any of it get staggering very quickly.
Wastewater isn’t rocket science. It’s just harder and significantly more important. Every engineering discipline makes fun of the civils, but the fact is none of us are half as critical to modern life as them. Every benefit any of us claim rests on their backs. The flow of electricity is a civil engineering feat, the flow of water to and from our homes, businesses, and farms is a civil engineering feat (and critical to health), as is our transportation networks, our entire constructed environment, and even crazy and weird shit like controlling the location of critical rivers.
oh I’m not shortchanging it, I work in the field. It’s crazy how “simple” it is in concept and hard to deliver. But it’s on par with antibiotics with how many lives it’s changed. Like you said, it’s like a lot of civil stuff. A solid highway system, for instance. Just some dirt with fancy rocks on it right? Righhhhhhht?
And don’t get me wrong, wastewater has tons of complications. Any plant is operated in equal parts science, engineering, and art. It’s a living, breathing, bioreactor. They’ve each got their own distinct personality.
I actually thought about going into civil engineering in school, but I ended up really liking Computer Science instead. In high school, I was waffling between being a software patent attorney and a civil engineering attorney, but once I took some CS classes, I decided software patents suck and I really wanted to work with computers.
I have a lot of respect for our civil engineers. My state is experimenting with a variety of civil engineering stuff, like paints for our highways (should help visibility in crappy winter conditions), alternative grass mixtures to cut water use (less engineering and more horticulture, but whatever), and expanding trains. I kind of wish I was involved with that, but I still really like my job, so I just follow that kind of stuff as a hobby. Bridges, trains, and tunnels rock.
Yeah in retrospect I wish I’d gone civil. It wasn’t offered at my school but I went industrial because I loved both engineering and psychology. Civil would’ve meant I did more good and got less poisoned by my career
Where does Santa Rosa’s wastewater go to?
It was also, literally, built by the mob
It’s funny, I think Vegas is perfectly fine as the city of sin so things like this really don’t phase me. It was built on the idea of crime and excess.
What does seem weird to me is how in a desert, why isn’t everything solar? The sun is their only natural resource besides sand. Every rooftop and parking lot and flat surface possible seems like it should be a panel.
Vegas is surrounded by empty desert, they don’t need to use rooftops and parking lots
even deserts host life. it’s kind of a ecological misnomer that we could just cover the deserts of the world in solar panels. that would have serious repercussions.
What repercussions could covering a few acres more in the mojave with solar panels have?
Honestly if we could get space elevators figured out, the best place to put solar panels would be in the upper atmosphere. Tethered to the ground by massive columns that feed the energy they collect to massive capacitors on the ground?

They say there are 16 screens inside, each with a 16k resolution. Such a screen would have 16x as many pixels as a 4k screen. The GPUs power those as well.
For the number of GPUs it appears to make sense. 150 GPUs for the equivalent of about 256 4k screens means each GPU handles ±2 4k screens. That doesn’t sound like a lot, but it could make sense.
The power draw of 28 MW still seems ridiculous to me though. They claim about 45 kW for the GPUs, which leaves 27955 kW for everything else. Even if we assume the screens are stupid and use 1 kw per 4k segment, that only accounts for 256 kW, leaving 27699 kW. Where the fuck does all that energy go?! Am I missing something?
This is a complete shot in the dark but could the huge power draw come from needing some intense industrial cooling/airflow stuff in/on the sphere?
Edit: forgot a word
The big power draw is because of the sheer amount of light it dumps out. You try lighting up 54,000 square meters of LED panel to a few hundred nits like a pc monitor, and see how much power it takes.
More likely it’s the thing that generates all that heat in the first place.

In the future there will be myths that we once had standards such as html but after we tried to build this sphere, god cursed us to use only incompatible proprietary protocols
Yeah, 4k phone and 4k plasma tv don’t consume same ammount of energy.
Says 16K, where’s the disconnect? (I don’t know display tech)
deleted by creator
Anything most likely driving factor here?
Extreme resolution requirements, massive number of LED elements, real-time rendering and synchronization needs, complex content processing, load distribution and redundancy, future-proofing capabilities, fraudulent kickback scheme
That’s the outside. The inside is 256 million pixels.
And a waste of electricity?
Its one of the smaller atrocities in Vegas, particularly when compared to the Bellagio Fountain or the food waste generated by all those casino dining halls.
The fountains aren’t quite as wasteful as they seem. They use a lot of water compared to a house, but way less than some car washes.
Plus it is recycled. They would only replace what is lost due to evaporation or after a drain and cleaning.
Yeah we should have never invented televisions or records either! And don’t even get me started on cell phones. Just waste waste waste.
Why, if it were up to me we would all still be hunting and gathering!
Apples to oranges dude, this is for pure spectacle that wears off after five minutes. Plus any data gained from it was at the lab they prototyped it I believe in Burbank. This aint really a sign of progress, and itll be funny to see what happens to it when it inevitably breaks.
Add a solar array and battery bank, a you might even have electricity left over. It’s in the desert after all.
Have you ever seen a solar array that gives 28 MW?
Is it bigger or smaller than a football field?
Rough calculation says it needs about 28 ha, this could be about 30 football fields (depending on whatever they mean in your area when they say football :))
Thank you for doing the math.
110MW https://en.m.wikipedia.org/wiki/Crescent_Dunes_Solar_Energy_Project
392MW https://en.m.wikipedia.org/wiki/Ivanpah_Solar_Power_Facility
These are both near Vegas.
So?
Or how about six wind turbines? It’s rather windy in Las Vegas.
I mean, have you seen it with your own eyes?
I’ve flown over a couple big ones. Not sure of the exactly area or output.
Is the ‘dystopia-sphere’ trying to compete with the torment nexus or something?
Thunderdome was already taken
I mean it is cool. But really a testament to why we deserve extinction at this point…
If they reversed it (displays inside), it would be the best immersive gaming setup ever.
Edit: looks like they are inside.
That’s what it is on the inside.
Wait, the article says it’s “internal displays” but the picture shows images on the outside of the globe?
Yep, it is both. Highly recommend this amazing video from Eddie Burbank about it, very entertaining. https://youtu.be/KN63DDD9Y04?si=q6gE98LszfcPzBvy
It’s got both. It’s awesome. But it’s also owned by James Dolan, and he’s a douche. I say that as a big Rangers fan.
The article says
Those GPUs power 16 internal displays, each with a resolution of 16K, alongside 1.2 million programmable LED pucks coating the exterior of the sphere.
Did you literally stop reading mid sentence? Or are you just not able to read good?
“internal displays” could mean whatever. They’re embedded for example.
So not read good. Thanks
Except it has the worst pixel density ever
9.818127340823 should be the pixel density if my numbers are correct.
The numbers i was able to find(please correct if these numbers are not accurate)
160,000 sqft display converted to inches 23040000 sq/inch
16K x 16K resolution equals 15360 pixels x 15360 pixels So thats 235,929,600 pixels
Various Notes.
- a 55-inch 4K television, which has a pixel density of only 80.11ppi
- iphone 12 - 360ppi
- 14,000ppi MicroLED display is world’s densest, only 0.48mm across june 2019 approximately the size of a ladybug
Thank you for confirming this, I’ll stick with my 109ppi 27" 1440p 165hz monitor
Not even close to the worst pixel per inch though. That would be probably a drone array in the sky im guessing assuming they could be made to stay perfectly in sync, ppi could be as bad as you wanted it lol. This does make me wonder what the extreme limits of ppi can be and still be usable. You would probably need to be on the moon or in space to be in the ideal viewing position. Having to acount for the limitation of the speed of light to produce the picture on that “display” would be an impressive feat of engineering.
Did you really build a dyson sphere just to build a bigger tv? Yes yes i did
Pixel pitch takes into account viewing distance.
The displays in the sphere are 16K displays. They look insanely better than your monitor from the ideal spot in the venue.
Their display has 64x more pixels than yours.
Silence! I will hear none of this blasphemy! Fallout 76 does not have 16x the detail!
A bomb that could destroy Earth’s core would be an admittedly impressive technical feat!
Might as well just give up on the earth right now I guess
Useless
That article gets stuck so much and makes my (relatively high end) laptop’s fan scream so hard you’d think the website was designed for that kind of hardware.
