It’s not difficult, but it is expensive and inefficient. There are very few financially viable battery technologies on the market currently, and although incremental improvements are happening on that front, there are also roadblocks (lack of raw materials like cobalt, toxic metals, thermal runaway fire risks), we really need a big breakthrough before we’ll see large adoption of batteries.
There are literally countries that went all in on nuclear power (france and switzerland come to mind), that now regret that play and are trying to transition away from them. Not for safety reasons, just because they are extremely expensive to operate and they become a money pit when renewables eat away at the base load that they were built to supply. You have nuclear plants paying people to take their power during the afternoons because they cant shut down quickly when the sun comes out.
As others have commented, the open source home assistant project can take voice commands and perform smart home functions like turning lights on and off, reading off the forecast, taking down notes, etc etc. But it does have limits, you will have to script any kind of complex commands, like pulling headlines from an RSS feed, or playing spotify playlists, or really anything that requires fetching info from an API, it won’t do those kinds of things out of the box.
The other factor which others have called out is that it doesn’t currently handle wake word functionality, though that’s been on their road map this year and the Oct update might fix that. That being said, running a dedicated wake word app to fill in that gap is very much possible. See my thread here for more info: https://community.home-assistant.io/t/setting-up-a-100-local-smart-speaker-on-an-android-tablet-using-tasker-and-snowboy-to-handle-wake-word-detection/611435
Same, including an IR led is such a simple thing, why did this ever go away. Though I’m pretty sure most Chinese phones still have them, Xiaomi phones do for sure
Hell yes, just jumped on the ulefone train myself!
I actually meant to reply to your comment but replied to the main thread by mistake, I had the same frustrations with modern phones losing features, and even fairphone dropping the 3.5mm jack was a wtf decision to me. See my comment on the ulephone 18t, it had virutally everything I wanted in a phone.
I’m going to chime in here to plug the ulefone power armor 18t I just got. I was pretty nervous to get a chinese phone as I’ve only had samsung and lg phones before, but this thing legit blows me away. Not only does it fully support every band that my carrier uses (rare even for phones made for the US market), but it has:
Replaceable battery that lasts 3+ days between recharges
Extremely rugged, IP69 waterproof and designed for underwater photography (physical shutter button and diving camera app)
3.5mm jack, sd card slot, FM radio (with built in antenna - no headphones need to be plugged in), and an RGB notification led
Dimensity 900 chipset that beats a lot of the snapdragon chips on the market.
12 fucking GB of RAM… yes, 12…
Wifi 6(ax)
Wireless charging and reverse charging
A fucking 60x magnification microscope? (Why???)
A FLIR thermal camera (Just because, why the fuck not)
Runs mostly bloat free stock android
All that for under $600 (on aliexpress)
The only thing it’s missing is an IR blaster, otherwise this is the best phone I’ve ever had, bar none. It is a chonky beast though, be warned.
This has really changed my view on Chinese electronics, especially at a time when phones for the western world are losing features and functionality all the time (including stuff from South Korean). Turns out capitalism isn’t that great for innovation!
Because color is photons in a narrow range of wavelengths/energies visible to the human eye. Atoms have electrons that can emit and absorb photons under certain circumstances, but don’t have any intrinsic color themselves.
Color charge is a property of quarks thats trinary in nature, and is usually described in terms of red, green, and blue, since color is a useful analogy to how it functions. Despite the name, colored light and color charge are not actually related outside of the analogy.
The answer is no, but if you take an imaginative view of color charge in quarks then yes!
Could it be worse than giving them to power hungry octogenarians?
Reducing dependence on their aging expensive nuclear power infrastructure has been a campaign promise of every French president for the last decade. Switzerland just voted via referendum to shutter their nuclear fleet, Germany has phased out nukes almost entirely.
The reality of it is: They’re expensive. They generate waste which could theoretically be reused or even locked away in underground vaults, but it’s frequently just stored on site in reality. And whether the danger is real or perceived, no one wants to live next to a nuke, because if things go wrong, they go very wrong.
Don’t get me wrong, I would love to see nukes make a comeback, I think they’re a valuable part of the energy mix. I actually know a guy in crypto who is trying to set up financially strained nuclear plants with on-site crypto miners to help them gain back some of that lost revenue from paying people to take power during light load periods. Which I think is a fantastic use case and a great way to make Bitcoin less environmentally destructive. There are other dispatchable loads that could fill the same niche (water desalinization, green hydrogen production).
But the unfortunate reality is that nuclear plants are dying right now, and unless something big changes they’re going to be driven out of existence by wind and solar.
