  • If you don’t want to accept a present for your child because you think it’s bad then you say that. When a person offers a gift to your child and your immediate response is that you plan on selling it that makes you a dick

    Also how is this family both so poor that they need to sell the shoes for groceries but also so selective where they don’t want a practically new pair of popular mainstream shoes







  • 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






  • 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)
