OLED maybe but small micros are now so cheap and so small that they’re negligible.

Battery is probably still the biggest environmental impact.

‘Dumping’ is considered anti-competitive behaviour in a lot of places. This sounds a lot like that.

There are a number of 6-8GWe nuclear plants that dump 15+GW into the nearby sea (or in the case of Bruce, Lake Huron). I don’t see it being much of an issue. Better than virtually any other cooling option.

The issues are maintenance, energy source, and equipment supply.

OpenAI is joined at the hip with MS, right?

What’s the bet this is MS’s attempt at getting back into the corporate mobile space again? Brand it as CoPilot Phone…

RAM’s main advantage over HDDs/SSDs is fast access times.

Needing to fetch anything over the internet would make it faster to just use HDDs.

PCs have almost never supported CEC. PCs use a different signalling method to indicate to the monitor that they’re on/off.

That is sort of what sponsored segments are, and what sponsorblock is quite effective at dealing with.

If they’re injected on the fly at variable time points, it gets harder, but I suspect fingerprinting could work well enough.

TVs often do a bad job at switching on when the computer turns on, then off when it turns off/goes to sleep. Drives me spare. That was fixed in like 1995-2000 for normal monitors.

Cost-to-benefit analysis, sure. But you still need a realistic comparison of the costs side of the equation to do that.

People were whining about the energy costs of regular data centers long before AI came along.

That invites a lot of questions like is it lower carbon to have a zoom call than fly out for a meeting? Do the travel emissions of an imported tomato offset the heating emissions for a local out-of-season hothouse tomato? If I’m going to make one personal sacrifice, is it more effective to give up red meat, bike to work, or make my next holiday less far away?

Intentionally ignoring evidence is just dumb; decisions made purely on vibes are often going to be wrong.

So your alternative is what? Just say a tonne is a tonne?

It’s adequate for the purpose at hand.

Lots and lots of math and analysis.

My understanding is it is fairly well settled on a chemical & lifespan basis. I am not sure of what impact initial altitude has.

Anaerobic bacteria produce methane. When oxygen is present, the aerobic pathway outcompetes anaerobic because more energy is available, producing CO2 instead.

GHG are usually measured in tonnes of CO2 equivalent (GWP) where methane is about 80x as much warming as the same mass of CO2 over a 20 year period, or about 25x as much warming over a 100 year period.

This is also what’s going on in the steady replacement of various refrigerants with lower-GWP alternatives.

But all of those are net emissions?

A lot of the emissions from food are not things that are already in the carbon cycle.

• Deforestation to turn forest into farmland.

• Fossil fuels for equipment and to manufacture fertiliser.

• Methane from animals is significantly more potent than if that same carbon was released as CO2.

Cycling and rowing machines are probably the only practical options for that - they both have intentional friction brakes to dissipate energy, because they are actually efficient enough to need them.

Treadmills still need to put power in because of the friction, and most weight or spring machines rely on you absorbing the energy you just put in (unless you drop the weights…)

Even nightly doesn’t seem to be necessary; I’ve used those for years without issue

Coefficient of performance (i.e. energy efficiency) at decent delta-T is always the most important factor and rarely mentioned.

Modern cooling equipment generally has the largest environmental impact from energy consumption, not manufacturing or refrigerant leakage.

Especially with ultra-low-GWP propane or butane refrigerant, though that’s not usually used in large-scale systems.

Oh lordy.

U-series number plate; this is probably a pretty old photo of a pretty old bus.

Yeah, I need to figure out GSIs. Finding non-flagship phones with decent custom rom communities is getting harder.
