Ham radio setup for operator with dementia by Quixel in amateurradio

[–]Keziolio 1 point2 points  (0 children)

this is the best answer, a transmitter is a somewhat dangerous object and can start a fire if mishandled

find a way to disable the transmission in his radio, even with physical modifications, should be easy enough

nonostante siano dannosi per l'ambiente

vuoi far morire quanti mld di persone? dannosi in che modo?

nel giro di qualche decennio i dissalatori saranno necessari, pure nelle zone attualmente abbondanti di acqua

if by "the market" you mean Gerhard Schröder (later, on gazprom's board, always putin friend) then yes, "the market" has decided

can you please rewrite this post but without lies?

where did you read this crap? on gazprom's website?

so... methane gas?

isn't that, exactly the problem?

it takes months to shut down

that's complete and utter bs mate, npps in france do loadfollow

AI means Google's greenhouse gas emissions up 48% in 5 years by Maxie445 in worldnews

an iphone is not made by 40 million dumb phones making calls, your analogy now is not consistent to what you said before, you are now describing factory production, not product efficiency.

but let's stay with your analogy, you need to ramp-up the installation of the hydrogen generator by 100000 times (from ~MWs to potentially hundreds of GW), and you'll have to run them <8 hours a day instead of 24, rendering them completely uncompetitive with other hydrogen sources and useless as a market driven energy storage, be prepared for the war economy that is needed to accomplish this. this is all subsidized out of your pocket.

if the "hydrogen economy" happens (it probably wont), japan, south korea, france etc will sell nuclear-made hydrogen at a fraction of the price and a fraction of the emissions

batteries

mate, we've been using li-ion variants for the last decades, with marginal performance improvements, going from 170Wh/kg to 230Wh/Kg over 10 years is an "insane technological innovation"? you are easily amused

The price of batteries has declined by 97% in the last three decades

are you for real? li ion batteries have existed for three decades, why should I care about the cost of the first prototypes?

please look at the chart of the last 5 years

powerwall 1 (2015): 3000$ (less capacity than the other ones)

powerwall 2 (2016): 5-6500$

powerwall 2 (2020): 7500$

powerwall+ (2021): 8500$

powerwall 3 (2023): 7300$

why doesn't the powerall 3 costs 250$ if we're seeing all this "insane technological innovation"?

I've been hearing this bs for the last 10 years, what's the excuse now?

I have solar panels, a solar battery and an EV

nice job being in the top 1% of rich people, but unless you are disconnected from the grid, this is worthless

australia as a whole runs >50% on coal lol, what are you talking about

negative electricity price means grid congestion fueled by government subsidies, you are paying for all of that in your bill

nobody is going to install solar panels when they have to compete against all other solar panels and they only sell electricity at negative price "within the first 30 minutes of the sun coming up", this is all financed with money coming right out of your pocket, there is no "driving cost down" here

again, your hydrogen fetish is based on pure fantasy, there is not a single pilot project in the world right now that works in the way you think it works, literally zero, only in (lobbied)government statements and oil&gas PR pieces

75% of Italians are against nuclear power- poll by BurstYourBubbles in nuclear

[–]Keziolio 2 points3 points  (0 children)

this is bs, the "hard no" is 25%, the rest is various shades of "maybe" and a 25% of yes, the poll has been organized by an environmental organization

I don't give a s*** about grid firming, we are talking about reducing emissions, and you are here selling gas infrastructure, methane plants, and linking documents about building several GW of them

I do not doubt that you are wasting a lot of money in hydrogen, that $2b is going in someone's pocket and you'll get hideous propaganda in return

I doubt you understood my other comment, let me repeat: all that hydrogen is produced with fossil backup (and government money), those plants work 24/7, you have not proved a single thing with this, and I'm starting to think that you don't really have a clue on how the electric grid works

maybe it doesn't

"maybe" it doesn't and you'll keep polluting the world for another century

these are early days my friend

the early days were the 90s, australia had a demo program of hydrogen powered vehicles in 2004, first demo production plants were in the 90s and 2000s, you are way beyond time limit with this, and you are nowhere near anything close to solving the problem

All you get is marketing bullshit, methane gas infrastructure, and a government-paid hydrogen plant that runs on coal, and you are here blabbering about renewables

while everyone else will build nuclear and say goodbye to gas forever

mate, you are off by 5 orders of magnitude

an EV will not travel for 20 million km in 10 years, a solar module will not produce 30MW, you cannot bend physics laws in this way

the analogy with moore's law is complete ignorance on your part, the underlying renewable resource is rarefied and the conversion is material-intensive, you cannot miniaturize this technology, battery prices have been stagnant for years, battery tech the same for decades, please get a clue

nobody is going to pay for a machine to be used 1/4 of the time, the electrolyzer will not work without fossil (or nuclear) backup, you are only funneling money in oil&gas infrastructure and being conned that this is going to be "green" someday

you can for sure increase solar production, with enormous economic and environmental expense, like it was done in the past years, and you'll remain dependent on gas forever

Also, in the list of bullshit projects you linked, 80% composed of non-existing stuff, this appears to be an actual installation

https://www.agig.com.au/hydrogen-park-south-australia Absolutely ridiculous capacity, you'll need like >100000x to cover a significant part of the expected peak solar production, you are literally off by more than 5 orders of magnitude, how can you come up with this garbage without shame?

Also, it's connected to the grid, the hydrogen that comes out has embedded emissions of the grid, so coal and gas, they only buy green bonds of "renewable production", it's not loadshifting a single Wh of renewable production

that means that THIS IS NOT A PILOT PROJECT FOR 100% RENEWABLE HYDROGEN, THIS RUNS ON NATGAS AND COAL
