Das boot is the must-watch film of submarine crews, this is the cult movie of their trade. I've seen it more times than I can count, just by having worked with submariners, as temporary "live in" civilian Engineering support at sea.
I see what you are saying about Marx's idea of capital, and I think this is a very valuable view, but again urge caution against reading too much into it, Marx could not have imagined how different things would be in presence of actual significant use of solar energy, it changes things physically in ways we can only understand, even now, by following the physics through to conclusion, which is why I would recommend you try to absorb the fundamental physical concepts associated. As a long practicing Systems Engineer from a heavily scientific Engineering background, I can tell you some of these concepts have been missed by conventional science, which appears to have stepped round them for non technical, actually commercial reasons (Something we might recognise as maybe necessary scientific sales pitch, not quite a liars dividend, but very close). So as humbly as I can, would urge you to research my work in Medium, to understand just the required physical concepts.
As I've said before, you appear to have an incredible natural systems thinker's head, a head like the one I required many years of formal systems Engineering practice and training for me personally to attain, and I guess I might be about twice your age, so all credit to you. But don't let it go to your head, there are a few things you are missing, on the truth around solar, which I think would get you to finally seeing most of the picture clearly, which is what I interpret motivates you, a wish to see the whole picture, the "Red pill". Reading Marx again won't get you much closer to that, it seems to me, like I said, genius as he was, he could not possibly understand the world that even science fiction writers of the day could not fully predict.
