    With the right electric field you can generate (a small amount of) thrust our of ions in air flowing over a charged plane.

    One of the myth-busters “anti-gravity” devices they tested was actually (very weak) a static electric ion thruster.

    Pretty cool - but it did need electric power input.

    A researcher should offer a sufficient compensation package to get enough volunteers after explaining the risks. They should get independent medical advice too.

    They can still randomize within the volunteers with treatment / placebo, and maybe use quotas, but they’d just have to extend their trial period until they’d achieved a measurably representative treatment and control group and enough volunteers to test the hypothesis to the required level.

    This type of non-random sampling may very well have to be done anyway, for example if they needed the power to test efficacy and safety in all the potential dug interactions or co-morbidity scenarios. Not to mention any diagnosis requirement will also screen the sample which could be influenced by health care system resources and policies, not necessarily pure morbidity. So I think they can deal with non-random sampling in med research perfectly well.

    I don’t know much about nazis but I thought an important part of their rhetoric was to draw distinctions between types of human.

    So they’d not see “10bn humans”, they’d see maybe 100m aryan and 9.9bn “untermensch”; the latter being equivalent to rats available to be experimented on.

    I just find rats to be much more preferable, pleasant and considerate creatures than humans. I see humans as a single tier of unterratten; totally different hierarchcy.






  • Agreed, It’d be interesting to see the cost breakdowns.

    I guess you have to spend more on tracks to get higher speeds, but still to get to 600kph you must put a lot of electricity into that thing.

    If sort of feels like maglev should be able recover a decent amount of electricity during braking, but maybe there are practical constraints - or just too much loss to wind resistance.

    Maybe it comes down to just a handful of magnets round a few axles being cheaper than a long line of magnets the length of the track.
