  • It’s not stupidity. You need to invent the tools that are needed to make the tools that make the tools that make the tools that make the thing. China still hasn’t independently invented most of those tools yet, so they’ve been relying on finished tools from other countries. Being smart doesn’t wipe away the decades of research needed to make something. We all expect China to eventually be able to make an equivalent tool, but they’re working with a handicap of inexperience which was expected to take years of dedication to overcome. Which is why everybody is skeptical that China made this independently without outside help or knowledge.


  • Recently at work they replaced the AEDs with new models that support Children, and have a Spanish guide mode, super nice. But they also are now connected to the Internet so that they report any usage and order a new set of pads automatically, plus it has a bright screen constantly cycling through advertisement of what the device is. Also for some reason the power button isn’t actually a power button, and just triggers the start-up process while calling back to base, just like touching the on-screen buttons or pulling out the pads will do.

    What could go wrong?


  • HDMI came from the TV manufacturers and was earlier than DP. While DP came from VESA and Computer OEMs.

    HDMI being in TVs gave it a far wider penetration in the consumer market, and so when people wanted to hookup their laptops and other devices to TVs, they’d need HDMI.

    Ironically, as ports have been simplified to almost just USB-C on many devices, DP’s market share actually grows as it’s cheaper and easier to include for OEMs, and if the consumer has to buy an adapter anyway, it might as well be on their dime to pay for HDMI, rather than the phone or laptop maker.








  • but also we could rely on saudi arabia’s infinite sunny desert to produce h2 in sustainable quantites.

    Pretty much no country wants green energy to be a repeat of fossil fuels, where a few countries monopolize the energy production, so that’d never work. Nuclear could be an answer though, if countries stopped being paranoid about it and actually invested in new nuclear tech.

    if solar panels could become more efficient that also would be nice.

    I wish, but it’ll probably be a while, short of some kind of massive breakthrough, and definitely doesn’t completely justify the losses in hydrogen electrolysis.

    also because batteries would require african kids to mine for ur cathode (cobalt) and argentinian kids to mine for the anode (lithium). maybe solar panels are less impactful ?

    Yeah, we really need to get away from lithium-ion batteries, especially because of the limited geography of some of its components and the environmental impacts of mining them. There’s been some promising battery tech being researched, but no clear signs for what’s going to pan out or not yet. On the bright side, improved lithium extraction methods are in the pipeline, which could reduce the geological and environmental impacts of it enough to allow other countries to feel comfortable tapping their deposits, like the US.


  • Safe Hydrogen storage is possible, but development is still behind where it needs to be, especially when compared to batteries.

    The real issue with hydrogen though, is that we still suck at making it. Most of the cheap hydrogen on the market is from hydrocarbons, which isn’t exactly a renewable resource. Electrolysis as we currently do it is inefficient, with energy lost during production. Meanwhile, batteries can take energy straight from whatever source made it, with very little lost in the process, so it’s way more efficient.

    If Hydrogen production makes a breakthrough in the future, and hydrogen storage improves a bit more, it could quickly become viable, but that’s probably gonna be a while.
