The way I think it, it’s possible a really small number of GPUs would be enough to render the framebuffer, you’d just need an army of low-power graphics units to receive the data and render it on screens.
Having a high-power GPU for every screen is definitely a loss unless the render job is distributed really well and there’s also people around to admire the results at the distance where the pixel differences no longer matter. Which is to say, not here.
Wikipedia says it’s 16,000x16,000 (which is way less than I thought). The way the math works, that’s 16x as big as a 4k monitor, so 16 GPUs would make sense. And there’s a screen inside and one outside, so double that. But I also can’t figure out why it needs five times that. Redundancy? Poor optimization? I dunno.
Even if it’s just playing back videos, it still should compensate for the distortion of the spherical display. That’s a “simple” 3d transformation, but with the amount of pixels, coordinating between the GPUs and some redundancy, it doesn’t seem like an excessive amount of computing power.
The whole thing is still an impressive excess though…
“Capable of drawing 28,000,000 watts of power” doesn’t tell us anything. As was noted, it should’ve been given in megawatts (28 mW) or kilowatts (28,000 kW). Clickbait aside, how many kilowatt-hours (kWh) does it actually use?
28 mW isn’t that much energy, relatively speaking. As of 2015, Forbes estimated LV uses 8000 mW on an average summer day.
The potential is impressive. I doubt it pulls anywhere near that. Unless I did my math wrong, this seems sensationalist.
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.
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.
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.)
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.
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.
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.
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?
Vegas is almost entirely powered by the hoover dam. It’s already pretty green as far as energy goes. The question will be where do they get their power from in a few years when lake mead dries up.
In addition to the other thing, dams have a dramatic and disastrous impact on the ecology in the immediate area and the entire riparian system they connect to. It’s “green” in terms of emissions but they’re still harmful and we should be phasing them out for lower impact alternatives as much as possible.
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.
Ok, so it’s “capable of drawing” enough power for 20,000 homes in the area. How much does it actually use day to day? Does it dim at night and brighten in the daytime to keep those ads rolling in the sunshine?
Before the Sphere, the largest spherical building in the world (since 1989) was the Globe in Stockholm.
On it they sometimes project stuff on, which seems to be a way cheaper and energy efficient way than adding a billion LEDs.
Fun fact about the arena Globen, it’s actually the biggest piece in a art installation about our solar system, representing the sun. Pluto is about halfway up in Sweden.
It’s also the home arena of Swedens national ice hockey team.
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 :))

Wouldn’t just one GPU be enough to run the Sphere, or a I getting something wrong?
I remember hearing about that it’s not exactly high resolution, each “pixel” being a bunch of pretty large lamps.
The way I think it, it’s possible a really small number of GPUs would be enough to render the framebuffer, you’d just need an army of low-power graphics units to receive the data and render it on screens.

And there’s a screen inside and one outside, so double that. But I also can’t figure out why it needs five times that. Redundancy? Poor optimization? I dunno.
But wouldn’t that be only necessary if it needed to render real-time graphics at such a scale? If I’m correct, all its doing is playing back videos.
I think it’s doing some non-trivial amount of rendering, since it’s often syncing graphics with music played live.
Even if it’s just playing back videos, it still should compensate for the distortion of the spherical display. That’s a “simple” 3d transformation, but with the amount of pixels, coordinating between the GPUs and some redundancy, it doesn’t seem like an excessive amount of computing power.

Just Fyi, mW is milliwatts, and MW is megawatts. Agreed though, I doubt it draws that much day to day.
Thank you, I stand corrected!

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.
Vegas exists because of the BS.
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”.
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
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.

I mean it is cool. But really a testament to why we deserve extinction at this point…

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?
You all go ooo and aaaa then yell at oil companies for climate change.
God you guys cant have any fun. Yeah it uses power but cant we have cool things once and awhile?
We need more nuclear power ASAP

Might as well just give up on the earth right now I guess
They tried to build this abomination in London and it got shot down.

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.

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.
The power of 21000 homes for advertising.
What’s most impressive is that it is even legal.
Look upon my works ye mighty and despair.
