do u know that you’re on a lemmygrad community lol
10 from 700…
lemmy.ml. a more generalist instance run by the communist developers of lemmy
holy hell its almost to 500
the main point of fission is that it’s a clean form of power generation that is very consistent unlike solar or wind. batteries are supposed to help, but you still want a consistent form of power in case of a long stretch of bad luck with weather. Fusion is still decades off of being price competitive barring a major breakthrough in something like a roomtemp super conductor.
We also have reactors that do not have the ability to melt down, with the development of molten salt and thorium coming ever closer.
the first one just opened so I think it’s safe to say it’s now finally here!
try and pay attention to China honestly. the seriousness they treat climate change with is the only thing that gives me hope that we’ll beat it. some examples from very recently:
China’s embrace of rail and EVs stalls holiday petrol demand
China adds new clean power equivalent to UK’s entire electricity output
Shanghai to fully switch to new energy buses, taxis by 2027
China is on track to reach its clean energy targets this month… six years ahead of schedule
that’s actually crazy, has the Indian government tried to crack down on this or is it just an open secret?
ah thank you for the info! seems like something i should have learned in school, although I learned very little about protecting the environment in school tbh so it’s not that surprising
i had no clue sand was even a resource we could overuse, is it more of an exhausting local resources problem and we could pull from the like the sahara forever if we worked out the logistics/maybe need special types of sand or are we literally in danger of actually beginning to pull too much sand from literally everywhere?
been playing cs2 ( 🤢 ) and geometry dash

havent played any single player games in a bit
Capitalists still haven’t found a way to provide water to all of the 8 billion inhabitants of Planet Earth.
your mistake here is thinking they want to. if they wanted to, they would.
funny that my response to you directly was so similar! I would say, back of napkin math, that desalination being over 150x efficient than these new machines would make up the deficits so extremely quickly that it’s not even worth considering the long-term costs between the 2, the desalination plants beat these dehumidifiers that much more quickly.
to give you an idea of the level of efficiency we’re aiming for desalination with the latest tech rn, this paper from 2020* is saying that these news techs are shooting for under 3 Kwh/m3 power usage. so we would need a bare minimum 158x reduction in power usage just to match the most experimental of desalination techs. Now, it doesnt need to get quite this low to match desalination because of the problem with dealing with all the waste products from desalinating waste water, but it still means we need to get pretty close to that. so, what could be done to make this practical? a leap in tech akin to the level of progress we’ve seen in semiconductors, which seems very unlikely to me at this point in time. so, we will needs at bare minimum, 2 or 3 decades, if not centuries (if it’s possible at all) to match that.
*I admit this is just one paper I found in like 10 seconds of searching, but this matches with other stuff I’ve read about desalination vs de-humidification in the past. still, maybe we’ll all be super surprised and there’s some secret to easily drawing water out of the atmosphere that we’re all missing and we’ll discover and it will usher in a new age of easily accessible fresh water.
right but is this actually better than desalination plants and pipes to pump it further inland? my gut says no, this is just like several other previous machines promising to do the same thing with horrific efficiency compared to desalination plants that already struggle with efficiency. maybe 20, 30+ years in the future we will be able to use machines that directly suck water out of the air efficiently, but desalination still seems like your best bet, especially since desalination continues to improve.
cool tech, but I’'m sure it’s not anywhere near as effective/efficient as desalination plants and pipes to pump them further inland
I know this is you joking but for anyone unaware I imagine the read/write speeds are much much lower than NVMe SSDs so this would be bad to play games on comparatively
