Father; husband; mechanical engineer. Posting from my self-hosted Lemmy instance here in beautiful New Jersey. I also post from my Pixelfed instance.
Better than plastic explosives and shrapnel.
I wonder how they did it. Was the firmware hacked to make the batteries ignite or were separate explosives implanted in each pager?
We need hydrogen production because we need emissions free steel, fertilizer, and vehicle fuel. It’s also a good way to soak up excess electricity production. Sure, batteries can store energy arguably more efficiently, but they offer no practical benefits beyond that.
I think you are correct that it’s the car’s fault. I have an MPOW brand Bluetooth adapter that almost always works properly with my phone. I use it in my Mazda 3 that doesn’t have Bluetooth built in. My 2017 VW Golf (one year older than the MPOW adapter) does have Bluetooth and it frequently gives me trouble. However, I’m typically able to get the connection to work by disabling then reenabling Bluetooth on my smartphone. Resetting the VW head unit typically doesn’t help, which is the opposite of what I’d expect if the problem was with the car. The VW has Android Auto over USB, which I thought would be the end of my Bluetooth woes, but that has enough of its own problems that I just keep putting up with the Bluetooth.
How about a version that successfully connects to my car’s sound system right away, every time?
Okay, district heating with a heat pump makes more sense to me if there are processes that require cooling and can act as the source, like lowering the temperature of treated wastewater before adding it back to a waterway. However, the heat supply for the water treatment plant should still probably come from cogeneration. District cooling with a central heat pump system also makes sense, especially if it eliminates noisy condensers on the sides of buildings.
What about when you don’t have excess solar power? People need heat when they need heat, not just on sunny days. So, you’d need a massive battery for that, which has some undesirable implications. Instead, a thermal plant (be it solar, geothermal, or nuclear) can be designed to reliably satisfy heating and electricity demand with excess electricity going to hydrogen production for emissions-free steel, fertilizer, and vehicle fuel.
Nothing wrong with putting nuclear power plant next to where people live and work. They produce good steam for residential and industrial uses.
I guess this is cool, but even though it’s an efficient heat pump it’s still a poor use of electricity. It would make more sense to use cogeneration, to use the incidental heat from a thermal power plant, for district heating.
Thank you!
Mechanical engineer here self-hosting my own Lemmy and Pixelfed instances in a Yunohost VM on an old Ubuntu box. It just feels better being my own admin.
Or a brand new set of DNA altering forever chemicals.
I know it’s okay to throw away traditional alkaline battery cells in the trash or the ocean or whatever, but I always thought that doing so was improper, so I’ve just been collecting a bag of them thinking that I’ll eventually figure out how to dispose of them properly. The article implies that it’s proper to just throw them in the trash. Is that true?
I think Yunohost is great. It was easier for me to set up that trying to figure out Docker. I run a few sites including AdGuard Home as well as personal Pixelfed and Lemmy instances with it in a VM on an older Ubuntu box. That said, I’m stuck on Lemmy 0.18.2 without pict-rs because the update script to the latest version available on Yunohost (0.18.3 with pict-rs) is broken. Oh well!
We can barely build and deploy fast charging infrastructure. It just doesn’t make sense trying to use BEVs for long distance travel.
Then take mass transit or get a car that runs on fuel. Having all this extra battery mass everywhere is just bad all around.
At the very least, vehicle batteries and fuel tanks should be limited to prevent drivers from driving too long without a break. It’s kind of reckless to put 600 mile battery in a personal vehicle.
A big tank in a fueled personal vehicle makes sense because you don’t want to have to stop and fill up every day. However, big battery in an EV doesn’t really make sense since it should be plugged in every day when you get home for a few hours.
