  • RISC-V isn’t in the same scenario. There’s one company behind ARM with a few external companies with architecture licenses (who doesn’t share their contributions), and ARM competes mostly just on the same commercial terms so for a long time it wasn’t worth investing in single core performance because they could instead fill the efficiency niche.

    Also there’s more knowledge on how to build high performance cores. Doesn’t mean it’s trivial, but it means the lead isn’t several decades. With enough investment you can make it happen faster. And there’s a national security motivation for investing.














  • Those efficiencies are for large senders and receivers. When you have to make it small for a drone the numbers gets worse.

    None of those make continous evasive maneuvers. All the things you mention works because the flight path is fully known in advance and you have full synchronization and ability to lock orientation. None of this works on a drone in urban environments where you’ll constantly lose line of sight.

    Dude I’m not talking about heat I’m talking about literal about the literal MW receiver’s physical LOCATION on the drone body AND THE ACTUAL PROPULSION IN FORM OF MOVING AIR, because the receiver has to be large, and oriented to the sender at all times, which means there are orientations in which it will block at least some propellers from pushing air physically downwards, unless those also are built to extend far out AND CAN TWIST THEIR ORIENTATION TOO

    (remember that propeller flight obeys the laws of Newton, pushing air down keeps you up and if you tilt your drone to align with the microwave center then you must tilt your propellers or you’ll be flying sideways, unless you put receiver on a gimbal in which case it’s stupidly complex and you now have to adjust airflow across non-blocked propellers when the receiver is below some of them)

    You can not win an argument by misunderstanding the counterarguments. You lose by not even being able to imagine how a drone actually flies physically in the air, not to mention your lack of ability to just read

    Not to mention that you didn’t even ask yourself what happens to a microwaved power transmitter in war. Guess what? It gets targeted and destroyed in seconds. You’re dead now. Bye.

    And you can’t even make a drone swarm work. Either you have a dozen transmitters (lol good luck) or a phased antenna array in which lol fucking lmao that thing will spew out heat losses and get banned from operating near any remotely populated area due to radio interference


  • If you think that’s not practical, wait until you see something microwave powered trying to make quick moves. I want to see what you think it will do when it suddenly has to pass through an urban environment with a ton of obstacles. Are you gonna MIMO the damned microwave beam!?!?!? With millisecond trajectory updates!?!?!?

    Not mention that a microwave power transmitter in war will die faster than any mobile radar station because it’s so god damned trivial to detect and lock onto, you’re losing that bullshit in seconds of turning it on

    The only scenario where this wouldn’t be total bullshit is perimeter monitoring drones flying a fixed path, where you for some reason really don’t want to have to have multiple drones in rotation (which honestly doesn’t make much sense either but at least that’s just 80% BS instead of 100% BS)
