That's why it was so refreshing to me to read "Release That Witch" (the webnovel, not the manga - the manga is... okay and more interesting to just see the characters since there was basically no real art for RTW's webnovel). I swear, the guy that did that must've been a former engineer that got laid off or something because he knew his shit from such a base, foundational level and up that if he wasn't in a line of work like that then he must've researched his ass off.
Some people raised eyebrows over a mechanical engineer having the knowledge he has, but honestly, it's not that far-fetched. Most STEM types that work in such fields tend to have overlapping knowledge and interests and tend to find these fields interesting and study on them. After all, when it came to chemistry, past the basics of what someone might learn in high school or in an introductory college course he didn't have enough knowledge past that to really help him. Which makes sense, that's kinda outside his purview.
If half of all isekais were written even half as well as Release That Witch is, the genre wouldn't be the absolute shitshow that it is. Sadly... It's easier just to throw lolis, kemonomimis and gargantuan-titted walking fanservice characters at you with game mechanics that rarely are like fully functional game mechanics.
