  • 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)








  • 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

    Supercritical CO2 has been looked at a lot for the Brayton cycle which can get 50% efficiency compared to steam that generally caps out around 34%

    The US and china both published studies talking about a brayton turbine but to my knowledge no commercial plants running off of it have been built yet
