Is it really cheaper and more practical to produce sodium vs hydrogen?
The typical issue with fuel cells is not energy density, it is the fact that you need to waste a lot of energy to regenerate and transport the fuel.
For example, if you take a classic hydrogen option, you can either get it from natural gas (which is not sustainable/eco-friendly) or from water (which is fully sustainable as you get a closed cycle, but comes with additional energy losses on electrolysis, transportation and usage).
Similarly, here with sodium you either have to produce it over and over from salt, or you'll have to regenerate soda, with the first option being wasteful and the second too energy-demanding and complicated.
So, overall, you'll need to spend much more energy (= both recurring and upfront costs) compared to running battery-powered transportation if you want to make it a close cycle similar to batteries.
On a serious note, female reproductive system is extremely fucked and overcomplicated and a great example of how evolution makes something that works, not something that is perfect.
The point is to avoid timezone confusion and simplify international cooperation. Inside the countries, there are some successful experiments: for example, China is present in 5 time zones, but the entire nation lives by UTC+8. And while 5 time zones are not 24, this arrangement is generally regarded positively by the people, despite the fact it's measured by Beijing, which is located on the east, and not by some point in the middle of the country.
Technically, a developer can contact vendors to include their keys to Secure Boot, but that would require asking all of them and them responding positively. So, in practice, it is commonly Microsoft that controls it since obviously just about any vendor will support their signatures.
No, I'm asking drivers to follow the rules designed to make driving safer, which is something a human is fully capable to do - and does whenever repercussions appear, like near the speed cams. If controlling that means installing speed cams at every corner, I'm all in. As long as it's not that, we have what we have to enforce those limits.
I also fully support and actively use public transportation and only engage in driving when necessary (which is actually quite little).
And please, do not jump to the conclusion about someone's mental health based on a comment on the Internet, this is rude and likely inaccurate. All I strongly state there is that it is insane to blame someone who follows the rules on the road instead of those who routinely break them out of habit and convenience.
I'm pretty sure those who have set it at 60mph have calculations you didn't consider.
Maybe there are places on the road where someone may suddenly appear, be it human or a wild animal? Maybe the road can get slippery? Maybe the cars going above 60mph create too much noise in the neighborhood? There are many more reasons one could set a road at that, and many may not even come to your mind.
And no, this is almost certainly not about tickets. If it is - screw them and follow the rule!
The danger is created in the first place by normalization of speeding.
I am aware that, technically, if I'd drive by traffic at any given time, accidents will be less likely. But this danger of variable speed is not created by me moving too slow, it's because of others moving too fast, because speeding is normalized in the first place, which introduces the problem that wouldn't otherwise be there. The lane speed should be within bounds of speed limit, the rest is not and should never be my problem or fault.
Now, don't get me wrong, if my actions can prevent an actually imminent accident (such as speeding up to let someone return to lane before reverse traffic traps them) - of course I will. But for regular driving, I strictly adhere to the rules and regulations. If this gets someone who breaks the rules in an accident - that's on them, maybe it'll teach them a lesson.
I fancy you don't have to release it in the air and can land with it.
And then you get free soda!
