The piano for when dodecaphony doesn’t subvert tonality nearly enough.
We’ve had flying cars for about 60 years. They’re called helicopters.
If they made you forget, why would they admit to it on a sign? Does that make any sense whatsoever?
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.
No iron clothes is a lie. They say no iron on the label in the store, but they tell you to iron in on the care label.
The meme shows only bikes with flat handlebars, like commuter bikes intended for transportation.
Every bike you posted are high performance racing bikes with specialized aerodynamic handlebars.
Different priorities. Triangless bikes with a top bar is not a good idea for commuter bicicles like the ones in the meme.
Imagine designing a bicycle without triangles. Every joint needs to be overbuilt, because there’s no structure from the geometry. But you make sure it still has a top tube, so its just as hard to mount and dismount as a normal bike. Incredible!
Since OS X they swapped the trash icon for an eject icon when you start dragging a removable disk. So they hint at it in some way.
Incidentally, this is why the trash icon is on the right side of the dock, and cannot be removed. You need it to eject disks due to a decision to account for the lack of a second mouse button.
Meanwhile apple tells you to put your removable media in the trash.
Its a reasonable assumption. Most of the visible foods are bulky items that are not stacked efficiently to be visible to the camera.
So maths time…
If that cart is a weeks of groceries, it takes 1250 weeks of groceries to buy a house in 1980.
According to a 2024 USA today article the average family with kids spends $331 per week on groceries.
If the groceries per house ratio stayed the same, a house would be $413,750 in 2024.
The U.S. median home price was $412,000 in September 2023, according to Redfin.
I dunno seems pretty proportionate.
Google has literally deployed crypomining malware through adsence. They don’t check ad code before deploying it.
That’s clearly two bears high fiving
They want to advertise a $2 chicken box without actually selling chicken for $2.
