To be fair neutrons are usually harder to block. Lead has a tenth thickness of 2” for gammas whereas the smallest tenth thickness for neutrons is around 6” for borated poly and the most common shields are water at 10” and concrete at 14”
So yeah it is different but overall it takes much thicker shields to block neutrons than gammas
Myth of Sisyphus is a great book if you want to lean into the absurdism
Modern subs are almost all nuclear powered so less of the diesel smell (still some from lubricants) but nuclear subs can be underwater for weeks at a time so they have to scrub the air which is an imperfect process that leads to some funky smells
If you remove the thermostat and redline it in a garage it still won’t be able to keep up because it doesn’t have the airflow that’s required
The concept of closed loop cooling for servers has always existed and it works for home computers. What is conventionally called closed loop cooling just means that you transfer heat from the computer to a liquid and then from the liquid to air. Transferring 100MW of heat to the air is what makes this difficulty especially in a stationary computer.
The problem is the rate that it leaves the local system is faster than the rate it returns so in the long term the local systems lose water. If you want to look at it even deeper it’s actually sooo much worse as it also causes local droughts which kill flora which then cause less water to be stored in the local system which then kills more flora and so on as you get desertification and then by pumping down aquifers those aquifers can collapse and never hold the same water that they used to hold
So yes it does fall back to the ground but that’s an explanation for a 10 year old learning about the water cycle. An adult should be aware of how much more damaging it is
Car cooling systems are stupidly expensive, run at temps that would damage computer CPUs, run outside, and have a really nice advantage over computers which is that at higher heat loads they also tend to go faster thus cooling them off faster.
Now imagine you redlined a dozen cars for days on end in a garage in the middle of the summer do you think you might damage some components?
It is still very possible to use closed loop cooling on data centers but any system you build needs to be able to work in summer temps which can be as high as 35-40C and needs to do that without letting the computers exceed 60C. An air cooled system to handle that much heat is going to be very expensive and use a ton of power (and power generation also uses water)
People mentioned corrosion which is true of all sea water systems but in evaporative systems you also have the addition of salt forming on all the evaporative surfaces which can drastically increase corrosion more than normal seawater and cause fouling
So to do this properly you would want an RO system making freshwater before the cooler which at that point it would make more sense to just have a separate company doing desalination.
It requires inference… maybe that’s a bit too complicated for you
Considering your restatement was wrong I am going to assume it’s you
“ How many cars are sold per year in the US compared to Europe?”
It’s a comparison between two places and one sells more than the other. The answer to which one sells more is the US
Well this is a waste of my time so I will leave you with one final look up. How many cars are sold per year in the US compared to Europe?
Hint the answer is the US
Imagine you owned a store, what seems better, having 40 customers come in and all of them buy or having 80 people come in and all use up time with a salesman and then only 45 people purchase. You would end up spending a much more significant amount of the sales revenue on the larger showroom and more staff. This isn’t my opinion this is why the American market has been prioritized, that and the fact that Americans spend more on cars per year
California has different emissions requirements (not safety) but since they are a strict upgrade to the rest of the US (and comparable to other int markets) as long as you follow their requirements all cars in the US can be sold without any contradictory requirements
A very common kpi used is to examine the success of a campaign in a per target demographic so having the much lower response rate is worse
If you are making an ad campaign, all of the US speaks the same language, generally has the same safety regulations, and a much larger percent of the people are your target ad personnel
The EU is a cohesive unit for regulations but speak many different language and once you branch out of the EU to all of Europe you can see why there are huge advantages to advertising in the US.
So no it’s not the absolute number that matters
There are around 290m cars in the us for the 330m people
There are around 420m cars in Europe for the 730m people
So while the actual amount of cars in all of Europe is more than the US the percent car ownership in a single country is insane
Sports players have a chance to give a message to a very large group of people. More people will see this then if an Iranian member of parliament makes a protest and Iran has condemned the attack numerous times
You are a billionaire you can custom design a new car with no spyware using reliable parts from other large brands
My 3 mile bike ride takes 2 minutes longer door to door than driving.
As has been repeated a few hundred times in this thread already, the part that makes it takes so long is car centric infrastructure. If you live in suburbia where you have a population density of 1k/mi2 (400/km2) you will have to travel a much more significant distance than if you live in a place that has 9k/mi2 (3500/km2)
Then with less car centric infrastructure the benefit of having parking right next to work starts to go away and the extra space can be used to shorten commutes as well
So why not keep time as a constant and if individual places want to change times they can do that
Even just single states can have vastly different sunrise and sunset times and changing 300m people’s schedules so that a few people can have a few extra minutes of sun in the morning for part of the year seems absolutely ridiculous
A local school district could very easily do a 1 hour shift as the sunrise gets later so that it properly aligns with their local school pickup times
It’s not a joke if you hit boron with a neutron it releases the energy in the form of an alpha particle which is just a helium atom.
So take some boron-10 put it in a neutron flux and you get helium. This is being done in nearly every nuclear power plant in the world every second
Helium may not be renewable but we can manufacture it from things like boron
A paper from around a decade ago talked about using WiFi to identify key strokes so with large data models we have today I would assume they could get pretty good fidelity on a person. Maybe not enough for “beyond a reasonable doubt” but probably enough where your WiFi company is selling your data on what you do at home
