that’s no problem at all, systems like that are in use

It’s easier to freeze water than to cool rock borehole

still 84% to go

Not really, there are also polyesters and polyamides. These used here are hydrocarbons, and turns out there’s a tool for that. You see, in oil refining there’s a lot of stuff manufactured that it’s useless without further processing, as in, after distillation and vacuum distillation you might end up with half of weight of oil or more as asphalt or heavy oils that barely can be sold. So in order to make them useful, these products are broken down into smaller molecules, and then are separated again. What they’re doing is similar to process called hydrocracking that is commonly used to turn heavy vacuum distillates, think something like motor oil or other greases, to diesel

If one were to make hydrogen producing solar farm specifically, this could have made sense if there were efficiency gains compared to pv + electrolyser. But there ain’t, and from what i understand won’t be

Ye i’ve seen that before. Perennial problem with this aporoach is that efficiency is capped below what pv panel can get and also now instead of wiring you need to install purified water + hydrogen plumbing. Also while you just can use only excess of generation for electrolysis, this is always on

no no no no it’s on by default so it’s opt-out, and switch for that isn’t even implemented yet

can you pull ethernet cable along power cables, wherever they are?

regular ethernet should work on this kind of distance, but it means digging

Mate do i have just the right thing for you, but it requires some soldering. It’s also probably cheapest solution working over longer range than you need

First you need two directional antennas. Use this https://lea.hamradio.si/~s53mv/wumca/cup.html the 13cm design specifically. Design of the dipole element is on another page https://lea.hamradio.si/~s53mv/wumca/sbfa.html They’re using hard to get semirigid coax but you can really just use common RG178 with braid tinned to make it stiff. This way you don’t have to leave D section they way they did, you can just solder core to the shield at the end while preserving total length (or ~1-2 mm less, because wifi is slightly higher frequency; 53-52 mm total). That dummy cable thing can be just any stiff piece of wire. Good way to get this would be getting a pack of u.fl-SMA pigtails, which you can also use for connection.

You also don’t need special aluminum housing like they do, cookie tin of the right size would be sufficient, or any other container of similar nature. If you can’t weatherproof it, putting it inside on windowsill is also fine

Then, plug TL-WN722N into it, or some other single-antenna thing, and you’re set. This one connects over USB and has removable RPSMA antenna, so you can connect it easily with correct cable (SMA plug - RPSMA plug)

to your new directional antenna. This thing works well over 200m distance, provided clear line of sight, and probably more than that

in my country it used to be like this for 50 years, you get flat rate per day, counted up to fractions of day, separately for accomodation and food + everything else. you only have to keep transportation tickets

behold, disruption

it’s straight up still not good enough

right after fusion power goes commercial, which also will power it all

neuralink endgame

lol nope they can’t do that because “guardrails” aren’t anywhere near reliable, and they won’t because it would cut into their profits userbase numbers, based on which they raise vc money. delusional chatbot user is just a recurrent subscriber

check again, works for me just as usual

it might be reddit just fucking up, i got the same error while logged in

i guess that fb does store keys after all; they do respond to police requests

i also found this: https://www.reddit.com/r/privacy/comments/v7tsou/is_whatsapp_lying_about_its_endtoend_encryption/

Encryption in WhatApp is actually a fake, because the encryption keys are generated and stored on Facebook’s servers, accordingly, they can read any of your messages as plain text, and the intelligence services obviously have access to them.

Also a few months ago there was a leaked slide from an FBI training course or something where they compared different messengers in terms of how well they cooperate with the police, guess who came first ?

WhatsApp provides data to the police in near real time (about 15 minutes from the time of the request)

The message from WhatApp at the beginning of the chat - that your data is not available to third parties is the height of hypocrisy.
