You can always attach a sterling engine to the waste heat of a system, its just diminishing returns.
Thats a very good point and makes me think about how funny it is that we are collecting energy through various forms of convoluted systems...I wonder if we can find some way to harness energy more directly. Thats probably more like renewable energy and nuclear though if I had to guess, which is also sorta convoluted because you putting effort into storage instead of ways of converting the energy into something useful.
The efficiency of converting random energy into useful energy (either mechanical or electrical) has always plagued engineering.
For computer systems your usually so concerned with getting the heat away, that your not even worried about energy capture. But if you had a large enough system you could make something, but probably not worth the effort for the complexity introduced.
Yeah Linus tech tios has made numerous videos about heating rooms or pools with stuff in his server racks. I think with a lot of heat produced like that the added compelxity is worthwhile especially if the person is somewhat knowledgeable, heck, I see more people going the server rack way more now that self hosting and other open source things are becoming a little more common, at least as far as online people goes.
Everything loops back to steam in the end. Solid state thermoelectric devices have been around forever, and before that we had the idea of using thermal energy to augment magnetic fields and jump to kinetic energy without any intermediary conversion. All very low yield results, but we've tried it anyway.
Keep thinking about it, we need all the brains we can get, but don't write it off as a novel idea that the other egg heads just haven't gotten around to solving yet.
I would do this if I could order it and have it arrive in a reasonable time.
Not really motivated to build it myself.
