Isn’t a crash screen the last place you should your branding?

Her plane is worse than most. Its one of the last trijets in production. Planes with a small number of large engines are more efficient than planes with many small engines, which is why modern planes are all twinjets with wide high-bypass engines.

Airlines care about fuel efficiency. A minor reduction in fuel burn results in increased profits, and they operate large fleets. A small increase in efficiency across an entire fleet is huge. If you own a private jet, you are spending huge amounts of money to have one, the cost of fuel would only be a minor concern.

The solution to private jets is regulation. Private jets don’t need to exist. They don’t need to be replaced by another kind of airplane. The solution is to replace all planes on overland routes with electrified rail. Let the rich buy private railcars for transport.

I’m not skeptical on the concept of small aircraft. I wanted to give context because very few people will picture bush planes and puddle jumpers from the mention of “commercial aviation.”

PS: My calculations for fuel burn were based on comparing the range to the fuel capacity. Those are the numbers I have ready access. Planes are much less efficient when the tanks are full, and swift’s plane has a longer range, so it’s probably not quite as bad as my calculations indicate on comparable flights.

The carbon comes from the fuel. Burning a ton of jet fuel will release the same amount of carbon regardless of the plane that burns it.

Taylor Swift’s plane is a Dassault Falcon 7X. It weighs around 17 tons and seats 12 to 16 passengers.

Her plane burns 60% less fuel than a 737 MAX 8. However, her plane holds 9% of the passengers of the MAX 8, so its far less efficient per passenger than typical commercial aircraft.

Private planes are not a huge contributor to carbon emissions in comparison to others. They’re bad, obviously. But there are far more commercial airplanes, and they fly much more frequently than private jets.

Private jets get people’s attention. One person being directly responsible for that much carbon is notable is unconscionable. But it’s the scale of transportation overall that is the issue.

I got the number from wikipedia. Following the references, the number came from a BP datasheet about Jet A-1, where it is listed on a typical properties table, and the number is the net specific energy, which means it accounts for the inefficiency of the engines. Or at least that’s my assumption.

All the weights listed were operating empty weight. The battery planes will be even smaller than the planes I listed for comparison.

Weights of planes vary in flight, so I picked the one that disadvantages the point I’m trying to make in the interest of fairness.

Trains don’t need to store the energy at all. Pantographs are a mature technology. High speed renewable long haul transportation is a technologically solved problem for all overland routes, it just requires infrastructure investment.

The plane in the article is a 4 ton airplane, they mention plans to make an 8 ton commercial aircraft.

The Learjet 31 is 4.4 tons. It seats 8 passengers. The Cessna CitationJet CJ3+ is right around 4 tons with a maximum of 9 passengers.

The future 8 ton aircraft is around the size of the 10-ton Dash 8 Q200 with a maximum of 40 seats.

There are commercial uses for aircraft this small, but these jets are significantly smaller than most commercial aircraft.

For context jet fuel is around 9,720 Wh/L. However, energy density(energy per volume) is less important in aviation than specific energy(energy per mass) as weight is far more likely to be the limiting factor.

A standard lithium ion battery has 100-265 Wh/kg

The article claims 500 Wh/kg in this new battery.

Jet fuel has around 12,000 Wh/kg.

Though this is a major improvement in battery tech, batteries are unlikely to ever improve to the point to even approach the energy storage of liquid fuels.

Batteries cannot run commercial aviation as it currently exists. Battery planes will need to fly slower and shorter. There is no other way.

Roscosmos doesn’t consider clearing the launch tower to be a success. There is value in continuing to use proven technology.

The Soyuz is cheaper. Roscosmos is an objectively better rocket company.

If the us supported the two state solution, they wouldn’t have vetoed Palestine’s UN membership.

According to boeing’s website the last 737 order was in February from “unidentified customer(s).” Hmmmmmmmm

Several years is an understatement. At current rates of production it will take at least 14 years to fulfill all orders.

Those are orders for the 737. Not parts, newly constructed aircraft. Airbus’s similary sized A320 has a backlog of 7197 according to wikipedia.

True, but this article is specifically about the 737. Apart from the a220, none of the aircraft you listed are both in production and part of the 737’s market segment.

The a320 neo family has about 7000 orders awaiting delivery. It is not feasible to switch for most airlines for the reasons I previously mentioned.

The biggest limiting factor in airplanes is the production speed. Building airliners is slow which is why there are very long waiting lists. Nothing’s wrong that’s just planes. New planes are cheaper to operate so its a good idea to order new planes even if you’re not planning a significant expansion.

This is also why airlines will be slow to react to boeing’s safety record in orders. Switching orders means losing your place and going to the back of airbus’s waiting list.

I’m unhappy that after an update gdm has a logo of the distro I’m using. I don’t want people to be able to see what distro it is, that way I don’t get the fun of telling everyone that I use arch btw.

No other issues.

Do you really think the us is so small we can only arm one war at a time? Nonsense.

Gaza does show that the us has little say over how their weapons are used. There are serious consequences for crossing biden’s red line, like having to move the red line.

If the economy is booming and the median american is struggling, your metrics for analyzing the economy are faulty.

They will be using CGI characters, but it sounds like they hope to do a better job of it this time around. The 90s digital camera footage would be unusable for a modern game, beyond recasting and refilming I don’t see any other feasible way to make the FMV not look out of place in a modern game.

One of the biggest technical challenges for Anderson and Gamiel has been bringing Riven’s characters back to life. The original game featured live-action video performances by several actors, including Rand Miller as Atrus, Sheila Goold and Regina Altay as his wife Catherine, and Royal Shakespeare Company alumnus John Keston as his father Gehn.

But it’s literally impossible to graft a 2D video from 1997 into a real-time, high-resolution 3D environment. Cyan’s previous remake, 2021’s award-winning VR and PC version of Myst, featured computer-generated characters in lieu of the original live-action performances. “It was… an experiment,” Miller laughs, but for the new Riven, Cyan hired a full-time animation lead, Autumn Palfenier, to raise the uncanny valley.

“For Gehn, we tried analyzing the [old] video and tracking certain features, but the resolution was so low, and it’s not even a full shot, so it just wasn’t doable,” Anderson says. Instead, they’ve been filming performances in Cyan’s basement using motion-capture technology.

“I can say on the record that this is a union production with SAG-AFTRA,” Gamiel says, referring to the same labor guild that represents Hollywood actors. “We wanted to get some incredible talent into this game.”

She won’t tell me who’s playing who but does confirm that Miller will return as Atrus and that the studio managed to salvage an old audio recording of John Keston, who died from COVID-19 complications in February 2022 at the age of 97. “We had an actor study John’s performance and then do it in sync with the original audio, so we got Gehn’s full body,” Anderson says. They show me a work-in-progress close-up of Gehn’s face, which exceeds my expectations.
