Under because that way you can model it by making a cylinder and adding a plane to it, because the plane is attached to the back you don’t have to do the extra work of making sure the textures line up.

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.
If the us supported the two state solution, they wouldn’t have vetoed Palestine’s UN membership.
They use a cold silicon gel that sets from your body heat to make the molds. It is an interesting expierence having a cold viscous gel squeezed into your ears.
Let me guess, you’re using unlock origin?
Google has literally deployed crypomining malware through adsence. They don’t check ad code before deploying it.
That’s a strange response when they claim they don’t recognize the court.
Either sign on to the agreement and file a motion in opposition, or refuse to recognize the court and ignore it, like a responsible adult.
They are acting like a baby having a temper tantrum. Grow up.
When american companies gutted american manufacturing to outsource those jobs to china, they did nothing to stop it. Apparently there was nothing wrong with any of what china does when it benefits american companies.
But now china has their own companies, now the profits from chinese business will stay in china, so they do a trade war.
This trade war with china is entirely driven by corruption and racism.
I made the mistake of buying an ebook once. I will never make that mistake again.
Fuck drm forever. Physical only. I will never pay for a file I can’t even open using my normal document viewer.
Healthcare in the US is run for profit. From 2020 estimates, they charge $1.6 million for a heart transplant. $1.3 million to transplant a pair of lungs, $880 thousand for a liver, and $440 thousand for a kidney. This is what for profit hospitals charge patients while giving your next of kin nothing for the organs that made it possible.
They don’t pay you for your organs. They will still bill your estate for any care other than the organ removal despite your generosity.
I would happily be an organ donor in a country with a non-profit healthcare system. But because of how heathcare is run in this country, I would rather my organs be left to rot.
Because authors and editors don’t trust their readers to know how quotes work so they add (sic) so you don’t blame them for the typos or faulty logic in the quote.
Tennessee is a state and capitals are cities. So the author added (sic). I despise this practice.
