    I have a compliant : sometimes there a proliferation of anti-scientific posts, in example I can mention those related to the "50 years nuclear battery", I remember particularly one…

    It's a bad idea for many reasons: - you are spending hundreds of millions for a prototype , on paper all works but in reality to build a reliable submarine you need peoples, experi…

    Following your reasoning an airplane can't be hijacked because it's difficult to operate: in reality you only need a gun to operate anything, in right circumstances.

    I guess like you do for airplanes: the fact a plane can fly don't make it immune to hijacking. Example: you wait the sub is in the port, is moored, etc

    PS: NASA , I really want to watch the mission live on TV, like my grandfather, so please don't make flying pigs.

    I agree, this reminds me RFC 1925 ( https://datatracker.ietf.org/doc/html/rfc1925 ), that states: "With sufficient thrust, pigs fly just fine. However, this is not necessarily a go…

    the answer is no, I was reading the linked documents and: 1. yes UVC of that frequency kill virus but they don't provide results about human safety, the say "potentially": "Germici…

    1. absolutely no, the article talk explicitly of "phones and drones"; 2. No, it's related to "phones and drones", I've explicitly written that this device make sense in niche appli…

    I think you are trolling, but, in case I'm wrong, I explain the concept in other words: modern phones need a charger able to provide current to the phone battery in order of Ampere…

    It's not matter of skepticism, it can't work and it's matter of science, it doesn't work both as generator to "recharge" the battery (at microwatt scale it needs years ) and as gen…

    P.s. More critical thinking is required before reposting this kind of article, those are, anyway, all very similar: computer generated mock, no test, no prototype, no scientific do…
