  • It boils down to chemistry. The nickle-metal-hydride chemistry used in rechargeable batteries just don’t produce 1.5V (explaining why is a lot more complicated), while the alkaline chemistry in non-rechargable batteries produces slightly more volts.In the same vein, lithium-ion batteries produce around 3.6V, while lead-acid produce about 12.4V.

    To answer your other question, they should be able to power most things that aren’t an analog clock (which might run slightly slow).



  • That’s fair, although I think that depends a lot on the type of car you drive. There’s an option to tell Maps what type of car you drive (electric, hybrid, or gas), which will change the results, because cars with regenerative breaking often get better “city” milage than “highway” milage.

    It also probably depends on factors like how aerodynamic your vehicle is, because it makes a huge difference above ~50mph (air resistance/drag increases exponentially with speed)




  • One thing to keep in mind: if someone gave you a 5.25" floppy disk with this type of data on it, even if the data was perfectly readable, would you have any way to do it? You’d need to hunt down someone whos into retro technology and hope you can figure out how to decode the information. The format itself became obsolete, so even if the data would theoretically be accessible, the means to access said data may not be.

    Point is, what are the chances that CD drives will be around in hundreds of years outside of a museum or personal collection? They’re already becoming more and more uncommon after only a couple decades. But there really isn’t a great solution to this, especially when it comes to video, because you can’t just print it out.

    Side note, are you sure that CD Golds are more durable than M-Disk?





  • As long as the “ROM” isn’t actually an executable file (such as a .exe), you should be safe. Some shady websites will tell you that you’re downloading a ROM, but are really downloading a malware installer, so you have to watch out. But as long as you’re downloading an actual ROM file (the type of file is different for each console, but Google says that most PS2 ROMs should be a .ISO file), you’re probably fine.

    Disclaimer: there is always a risk when pirating files. Make sure you use an ad blocker and don’t accidentally click on any fake download links.





  • That’s what I thought too, but this system doesn’t actually use salt water. It uses a membrane that’s filled with lithium bromide (a “salt” in the chemical sense of the word), which absorbs moisture from the air while the computer is off and then is able to slowly “sweat” the moisture away while the computer is running. They say it can run for about 6.5 hours before needing to be recharged.

    This is pretty cool for data centers which use massive amounts of power to keep everything cool, because it’s passive and doesn’t use any extra energy for fans or water pumps or anything. It really isn’t all that great for consumer PCs though, because it’s a lot easier to deal with waste heat.
