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.
Titty money is just going online, taking business from brick and mortar. OnlyFans probably makes more than ever today.
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.
Was this the first firework of the series? It looks really clean without any smoke, great capture.
