Pretty sure humans can live on submarines for extended periods of time..

dds still mandate vitamin D supplements + set day/night cycles to mimic sun; even 40 fathoms deep they fake zeitgeber cues. so yeah, artificial light works if it copies the real deal, but scrolling in bed at 2 am isn’t the same thing.
Sure. Agree there. Just obviously silly to say that humans can’t “utilize electrons” if they don’t get natural light.
What is the efficiency? I’d imagine the life quality and expectancy if you lived your whole life in a submarine would be pretty shit. You pointing out very extreme cases but if you want to live life to your full potential you need the sun.
The argument isn’t that you can’t survive without sun the argument is what is causing the modern disease epidemic. Humans are very resilient and hard to kill but I want to thrive not survive.
