What gives you the right to feel ashamed on behalf of someone else's actions, just because you're of the same race as them? Shame on you, virtue-chaser.
Are men any more attracted to a woman if she's tanned or not? Have they ever been? The status involved changes, and women find status attractive, but men don't care as much when it comes to what to fuck.
And have men ever not appreciated a nice, big ass?
For that matter, there's variance in what people like today; presumably there was before. And yet there are invariants- clear skin, symmetrical face/body plan.
Some of the differences in what's attractive (which breast/ass size is most attractive) also have to do with the life history strategy of the man in question. Pump and dump-oriented guys are more likely to find larger breasts most exciting (you have 10 seconds to pick the most genetically fit woman out of this lineup and 10 minutes to inseminate her; then you'll never see her again. What strategy works? Select for oversized secondary sex characteristics, female equivalent to peacock tails- costly signal of excess resources), whereas slower life-history strategy men will find smaller breasts more attractive and care about women's intelligence more (slow strategy- order, planning, division of labour, stability).
There are at least some proposals that use ionised particles in the earth's upper atmosphere as a conductive elements, meaning you don't need a loop as such- just a wire pointing towards the earth with a big metal ball on the end. Lorentz force means you can accelerate prograde or retrograde.
I find it fascinating to use the natural things you have available as a motive force, and it's really cool to think all you might need is a few bits of conductor and the earth's own relatively static magnetic field to move a satellite around.
I wish humans were less interested in the noisy, explosive things like engines and rockets, and more into subtlety.
