Hydrogen vehicles in Denmark left without fuel as all commercial refuelling stations shuttered
  • I hadn't thought of it before but it's obvious, hydrogen is a gas at room temperature, it had to be stored under pressure in order to get any significant mass into the volume of a tank. So it's under pressure in the refueling station and in the car's tank. How does it get from one to the other without boiling away?

  • Should an altruistic organ donor be allowed to restrict their donation to a specific group of people? (e.g. women, gingers)
  • I don’t think anyone just randomly donates a kidney, like you would give blood

    You would be wrong about that, in 2021 more than 450 people in the US anonymously donated a kidney to a non-familiy member (source). This is the scenario I'm asking about. One of the arguments given is that just as we allow monetary donations to specific groups of people, why not organs.

  • Should an altruistic organ donor be allowed to restrict their donation to a specific group of people? (e.g. women, gingers)

    An extreme version of this is: What should the German health service do if someone says they are willing to donate a kidney as long as it doesn't go to a Jew?

    On the one hand, nobody is forced to donate a kidney and by forbidding this we're making things worse for an innocent patient. On the other hand, it can be seen as the state sanctioning this kind of discrimination.

    What did you see?!
  • This is my issue with redditors deleting all their content from reddit. I agree with leaving because of the policy changes, but I think that adopting a scorched earth policy, mostly harms other users.
