  • We don’t even have automated battery replacement working on the ground, while stationary.

    Building aircraft with a whole bunch of their body and mass that significantly changes, in flight, is extremely expensive and difficult.

    Its why the V22 Osprey is widely regarded as a death trap, why we stopped building swing wing F-14s.

    … Have you ever tried to uh, remove your car’s rear seats, while on the highway, at 60 mph, and then also installed new seats, from a neaby car travelling alongside you?

    Ok now do that with aircraft, at 15k feet, going 600 mph.

    Yeah I’m sure that’ll be about as efficient as Elon Musk’s approach to designing the Starship+HeavyBooster.


  • Oh, ok.

    Even though this entire post is… about how it is small enough to fit on a drone, and efficient enough to power it for 3 hours.

    Ok.

    Gotcha.

    I’m not sure if you’re aware of this, but densely packed explosive bombs and missiles and warheads tend to be pretty heavy.

    … the entire problem with purely onboard solar powered vehicles of any kind is that they have to be absurdly lightweight, flimsy.

    That isn’t practical.

    It might be purely efficient, in a sense, but it isn’t very useful.

    Being able to actually move stuff, that is practical.

    Most transportation modes involve the ability to haul stuff.

    You know, do work, aka the capacity to make stuff move.

    You picking a fight that makes no sense to pick.

    You can have solar and batteries be more stationary, and use microwaves to power things that are more mobile, this post is literally the proof of that concept… you can charge a battery with a any kind of power source.

    Look heres another massive potential application of this, if you science fiction extend the accuracy/capability of this:

    Plop a bunch of solar panels/batteries in the L1 point between the Earth and the sun.

    Now, via a set of satellites in something like concentric orbits, you can get absurd amounts of power, beam it back along chains of satellites, snd then beam it to recieving stations on Earth. Or the Moon. Or orbital infrastructure.

    Microwave transmission power loss will be waaaay less in space, because there’s no atmosphere.

    Same with solar panel efficiency!

    Solar Power + Microwave Transmission = Very Good, Actually.

    So there is actually a semi-valid reason to find a lot of skeletons in bathrooms and not other places, in a post US nuclear apocalypse:

    A fair number of buildings are most structurally sound around the bathroom, because those room walls tend to be stronger/reinforced compared to other walls, to be able to handle all the plumbing.

    Bathrooms also tend to be located closer to the inside of the building, for basically the same reason.

    So, its pretty reasonable that if you heard the sirens go off, had only a minute or two… yeah, sheltering in the bathroom would be the optimal strategy, if you don’t have a basement/cellar.

    Horses are very often dumb idiot assholes.

    Much more so than dogs.

    Yes, they’re very, incredibly useful.

    Not really great ‘friend’ material though, more like you cajole them into helping you, and they maybe kind of trust you, sort of.

    Wolves that we domesticated into dogs literally evolved into having eyebrow and other facial muscles that allow them to convey emotion much more analgously to how humans do.



  • The entire AAA video game industry right now is basically freaking out, panicking and financially imploding right now, after at least a solid decade of mainly figuring out how to waste an enormous amount of money…

    While all trying to be the next big live service game.

    A live service game isn’t so much a game as it is a platform itself, a cash shop for in game content, a social media platform in itself.

    (See Roblox for an extremely problematic but successful version of pulling this off)

    These people all failed miserably at this, such that Ubisoft imploded, EA got bought out by Saudi Blood Money, Unity itself is imploding as an organization, MSFT switched its gaming division into pure wealth extraction mode before they shut it down in ~5 years and just act as IP liscensing overlords… etc.

    They all tried to establish vertically integrated businesses, and despise that they can’t come close to matching Valve, the most competent horizontally built business in the entire industry.

    And yes, the ‘video game industry’ includes nearly all ‘video game journalists’.

    These people are with few exceptions, allergic to doing any actual investigative journalism, they’re mostly just paid to manipulate the flow of discourse around video games, as a form of marketing.









  • It is comparable in the comparisons of the actual mechanics of the the shooting, and the subsequent government actions.

    They’re both assasination stories with dubious ‘official stories’ that have tons of problems and holes with them, as well as significant evidence of the government doing a coverup.

    And also, while you might not like to hear this, and trust me I don’t like saying it:

    Charlie Kirk was really important to a lot of people.

    He’s basically a canonized Saint/Martyr of the MAGA religion… millions of people really did, and still do, hold him in high regard.

    We can think he was a shitty person who said and did shitty things… that doesn’t negate that a lot of similarly shitty people thought/think very highly of him.

    They’re making monuments of him, naming streets after him.
