  • China’s ‘land aircraft carrier’ charges flying drone with microwave beam

    Jump

  • We already have concentrated microwave beams. And they do suffer immense energy loss on longer distances.

    If you want to transfer energy via microwaves, your efficency will reach single digits real fast on any meaningful distance.

    You are right that the inverse square law doesn't realistically apply with concentrated beams. But you still have energy loss. Lots of it.

    But don't take my word for it. https://www.nature.com/articles/s41598-022-25251-w

  • China’s ‘land aircraft carrier’ charges flying drone with microwave beam

    Jump

  • Yes but you are charging through a conductive cable. It's not even remotely the same as charging something with microwaves.

    The power delivered decreases exponentially with distance. I'm sure you've heard the phrase "inverse square law".

    Because you divide the effect and gain by 4pi(r^2) meaning your output is decreased by 75% every time you double the distance.

    You're going to need ridiculously powerful hardware and an enormous amount of electricity to run it on any meaningful distance.

  • How do you stop arguing with people on social media?

    Jump

  • I'm not exactly great at it myself... but my dad used to tell me a story from his job.

    There was a guy that made some claims, another desperately trying to correct him and tell him he's wrong. To no avail, afterwards, he turned to another person that had a doctorate in the very topic they were arguing about. And said "why didn't you say anything!? You know he is wrong!"

    To which the doctor replied "yeah, but it's not my problem that he's an idiot"

  • YouTube now lets you hide Shorts

  • Can we also turn off community posts? Why am I seeing them from random people I don't give a shit about. I don't even want to see them from the people I do care about.

  • They don't believe in other planets, at all. They're just projections on the firmament. Or some stupid shit like that.

    Kind of cool how every single government in the world all cooperate on this to give the illusion of a spherical earth. I mean, imagine how much money they spend on flying an airplane 24/7 to make it look like ISS is in space. And who's gonna project Saturn at all times just in case John over in Manchester wants to take a look with his telescope?

    A true marvel of human cooperation

  • Melania Trump tried to sweep the Epstein saga away, but she ended up reviving it

  • Don't call it a comeback, it's been here for years

  • D.C. Grand Jury Orders Reddit to Turn Over Data on Anonymous ICE Critic

    Jump

  • It will. I can assure you the government have far more resources at their disposal than you do.

  • Recently started jogging 30 minutes twice a week. When does it stop feeling like I'm dying?

    Jump

  • It doesn't. You just run faster.

  • And the fact that everyone else left alive had some form of immunity or resistance.

  • People who have been on Lemmy since the very initial reddit API debacle, or before even that, how much do you think it has changed?

    Jump

  • What is reddit? It's just a fast paced forum with lots of people.

    Lemmy is in essence the exact same thing. It just operates far more decentralised than reddit.

    The difference over the last months/years is that lemmy as a whole is growing. More people, more engagement. That's it.

    I don't know what you mean by "lost it's uniqueness" the only unique part of lemmy is it's decentralised system. And that's still the same.

  • A Republican Farmer Relies on Immigrant Work. He Sees His Party Erasing It.

    Jump

  • "he has tried to persuade politicians he supports"

    he never thought maybe he needs to change his approach after 20 fucking years or being unable to do so!?

    You are not supposed to persuade the politicians you support. The politicians are supposed to persuade you to support them.

  • Only 90s kids will understand

    Jump

  • You underestimate just how long the 90's stuck around in some parts.

    I was born in the 90's molded by the 90's, I didn't see the 2000's until I was already a man, and by then it was nothing but blinding.

    TIL sword yoga is a new fitness trend.

    Jump

  • I don't know NY law, but can you really just walk around with a sword in public?

    Also, if the goal is to feel empowered. Why not sign up for actual martial arts training like kick-boxing, judo, jujitsu or taekwondo?

  • Do you feel that use of generative AI and LLMs is ever justifiable? If so, when and where? If not, why not?

    Jump

  • I've always said I think it's fine in filler content, it can allow small teams to quickly populate their world with background stuff that you never notice. Except when it's not there.

    But with great power comes great responsibility. And I don't necssesarily think most can handle that.

  • I'd like to ask everyone, which movie have you rewatched more than three times?

    Jump

  • Holy shit, so so many. But I'll mention some favorites that I don't think everyone has seen.

    Top Secret, The Pentagon wars, Down Periscope, Men in Tights, CHIPS.

    I think they're all quite funny. But if I had to suggest just one, CHIPS will probably be a solid choice for most peoole. It's modern and really funny. (18+)

  • Honestly, the way they're speaking. I'm fine with them calling it "american".

    It gives the rest of us a heads up that we should use small words so they can understand.

  • ‘A very dangerous person’: alarm as Pete Hegseth revels in carnage of Iran war

    Jump

  • I knew he was incompetent and bad. But god damn, the more you read the worse it gets, you think: how much worse could it get? And then the article gently tells you: oh we're not done...

    But it also highlights the problem is far bigger than just Trump. As their Congress swore him in, after a 50-50 vote that was resolved by the VP.
