Blue hydrogen is made by stripping the hydrogen from fossil fuel hydrocarbons (chains of hydrogen and carbon, hence the name), and sequestering the carbon. It produces a fuel that contains enough chemical energy to be burned as fuel, but without the carbon atoms that would turn into greenhouse gases.
Most hydrogen currently produced though, is gray hydrogen (made from natural gas, but without sequestering the carbon, so that CO2 is emitted into the atmosphere).
Legacy nodes (known in the industry as "mature" nodes) remain in use after they're no longer cutting edge. Each run teaches lessons learned for improving yield or performance, so there's still room for improvement after mass production starts happening.
No, kw (power) is a fundamentally different unit from kwh (energy).
Energy is conserved, so that's how we use it and pay for it, but power capacity is very important for infrastructure. A battery that can hold 1 GWh worth of energy, but can only output it at a rate of 10 MW, might have a ton of limitations to its usefulness.
I will add that nodes don't stay still, either. A 2025 run on a node may have a bunch of improvements over a 2023 run on that same node.
And Google's jump from Samsung to TSMC itself might be a bigger jump than a typical year over year improvement. Although it could also mean growing pains there, too.
Fun coincidence from Newton's not quite right theory of gravity combined with his not quite right particle theory of light.
Well, by the time the Pixel 10 comes out, it'll be 2 generations after the iPhone that used a SoC from TSMC's 3nm node (the A17, used in iPhone 15 Pro, launched September 2023). I'd imagine it'll have caught up some, but will still behind while Apple is presumably launching something from TSMC's 2nm or A14 node at the same time.
Their algorithms are mostly public. Their training data/procedure, and the trained model's parameter weights, are not.
Price per kw and price per kwh stored. And price per kwh over the expected lifetime of the battery itself (longevity and reliability and safety and disposal will have to be factored into total cost of ownership).
The ceiling is going to be lower than with lithium. Sodium ions themselves weigh about 3 times more than lithium, for the same +1 charge. So it's not just that sodium is a certain number of years behind lithium. It's that it'll likely plateau at a point permanently behind where lithium will likely be.
Yeah, sounds like a phone call recording app that is allowed to operate on the App Store under the condition that the recording is loudly announced.
Or is a by product of its former format, the live laughs with a crowd while filming?
This is the reason. Television comedy derives from stage shows where the audience sits in one direction from the stage.
A lot of early television comedy programming was often from variety shows, where the live studio audience is an important feedback mechanism for the actual performers. A standup comic needs a laughing audience to respond to (and often, so do other stage performers, including sketch comedy).
So television comedy comes from that tradition, and a live audience was always included for certain types of programs. Even today, we expect variety shows to have audiences. For example, John Oliver's show without an audience felt kinda weird while that was going on in 2020. And even some pre-filmed sketch comedy shows, like Chappelle's Show, would record audiences watching the pre-recorded sketches as part of the audio track for the broadcast itself, while Chappelle himself was filmed essentially MCing for that audience and those sketches.
So sitcoms came up on sets with live performances before studio audiences, just like sketch comedies and variety shows or daytime talk shows. That multi camera sitcom format became its own aesthetic, with three-walled sets that were always filmed from one direction, with a live audience laughing and reacting. Even when they started using closed sets for safety and control (see the Fran Drescher stuff linked elsewhere in this thread), they preserved the look and feel of those types of shows.
Single camera sitcoms are much more popular now, after the 2000's showed that they could be hilarious, but they are significantly more expensive and complicated to shoot, as blocking and choreography and set design require a lot more conscious choices when the cameras can be anywhere in the room, pointed in any direction. So multi camera still exists.
Was this the first firework of the series? It looks really clean without any smoke, great capture.
