Home nuclear reactor: Sci fi or possibility

Disclaimer: i’m not planning to do anything of this. I don’t suggest trying any of this stuff without proper guidance ,knowledge and preventive measures.

Main questions:
 is it possible to make a safe, small scale reactor capable of providing energy for a medium class home? How much would be it’s price ?
How much knowledge would be needed to handle such a device? Would a housewife be able to handle it with newly developed technologies?

And if an accident happened:
How large would be the area of effect?

>>2784959
Definitely beyond the capabilities of a phoneposter.

>>2784959
There's proposals for neighborhood sized pebble bed thorium salt reactors with no maintenance.

You can't really go as small as ypu want because you need a certain amount of containment and fuel and downsizing has diminishing returns at a point and you go small enough and the fuel can't even function because there's not enough to react

>>2784962
I know haha
>>2784963
Thanks a lot. Very informative and interesting

If you can afford a nuclear reactor you better use that money for something else...

>>2784959
They already piloted pace makers with nuclear power in the 60s and 70s.
It’s not a hard or unsolved problem.
The issue is getting nuclear material in hands of citizens.
This is only legal in the U.S. if you are going to use the nuclear material as an armament and use it to kill other american citizens (originally it was only for killing the brits, should they invade or impose taxes).

>>2784979
nigga my smoke detectors have nuclear material in them

>>2784997
Nuclear decay and nuclear fission aren't the same.
Radioisotope thermal generators (plus something like a Stirling engine) are far more realistic and "safer" than nuclear reactors.
Still not reasonable or safe though.

Dont do it man big oil will hillbillary your ass<br>I made a funnel out of a heet bottle and big funnel is trying to get me bushwhacked over it

>>2784959
>is it possible to make a safe, small scale reactor capable of providing energy for a medium class home?
The RTG would be the size of a car.
The technology will be prohibitively expensive.
You'd need a masters degree in nuclear physics.
No. The housewife will be too busy in the kitchen.

>>2785016
Fission is a type of decay, just very rare in nature.
>>2784959
In theory, something like a radioisotope which generates heat from natural decay, you could use it to heat water. But to do so safely would probably be more expensive than something like a ground source heat pump.

>>2785205
that's spontaneous fission, i'm talking about induced fission by neutrons and in a chain reaction

All these comments, and no one mentioned LENR or the Thunderstorm Generator / Malcolm Bendall. Martin Fleischmann Memorial Foundation quantumheat.org

Short answer: nah
Long answer: Nope, it would be to expensive, even if you try to make ot the most compact design the reactor alone would be the size of one and a half cars give or take.
Second, you would need someone capacitated to run it, a nuclear reactor is not your good ol' diesel generator, between all the shit that need to be regulated, maintained and operated, there are maybe degree requirements in 17 diferent specialisations.
Next up, the components would be hell of expensive, the nuclear fuel alone (uranium, or thorium if you're based) are worth more than the house itself. There are cases of some guy's successfully making a nuclear reactor at their garage with minimal cost, like this guy (I don't remember the name, sorry) who brought a shit tone of smoke detectors to extract the radon to use as fuel.
Wich leads to the most important issue, security, modern nuclear power plants have self destruct mechanisms to prevent a reactor to going into meltdown and create a radioactive fallout.
But guess that, that's hella expensive and degree requesting too, I'm going to be honest, I can't just guess how far the contamination would extend in this scenario, but I guess is reasonable to assume that it would be really bad if it happens.
Unless a mayor advance in technology happens to make the technology more secure, compact and easy to operate (and I mean, sci-fi levels of technology advance) that will remain impossible.

> Neutrinos?
I doubt that. Neutrinos are picked up underground by huge water tanks usually.
It’s star-trek FUD to scare people into not messing with any of this stuff.

>>2784979
Also, D.U. rounds are plentiful, and shall not be infringed.

Ok here's my idea. You get a metal vacuum chamber like this, with an insulating pillar going into the middle. Down the middle of the pillar is a wire. On the pillar is held a piece of beta emitting isotope, especially nuclear waste like Strontium 90. The half life of this isotope is 28.8 years and the molar mass is 89.9g/mol. So for 1g of the stuff you'd start off getting 5.11E12 decays per second. Each electron emitted has an energy of 546keV so you'd get 2.79E18 eV/s, which is equal to 13W. Constantly, for a single gram, for decades. A kilogram could power a few houses. That assumes 100% efficiency of energy capture. Ideally, the electrons would charge up the outer shell to 546kV, so each electron that follows converts all of its kinetic energy into potential energy as it moves against the electrostatic field, preventing the heat buildup that makes RTGs so inefficient.

Also don't inspect gauss's law too closely.

>>2784997
>>2784979
Smoke detectors and pace makers?
I thought it was harder to contain it
At some point there will be night lights and wireless headsets powered by the same stuff

>>2785198
>You'd need a masters degree in nuclear physics.
I mean you don't.

>>2785867
not likely, we never even got to production level for vehicle sized. just too much bias. you should really look up david hahn he built a reactor in his shed, it's about the most based /diy/ story of all time.

>is it possible to make a [...] small scale reactor
yes, and the most well known example has been posted in this thread
>...[safe]...
how safe?
could you make it so no one dies? almost certainly, if it is very small
could you make it so it would pass inspection? with the skills, equipment and budget available to you: no
>capable of providing energy for a medium class home?
RTGs have been mentioned, but for a normal fission reactor: no this probably isn't practical for a single home for any amount of money, the smallest economically viable reactor would be too large
>How much would be it’s price ?
interesting question
it depends on whether this is a one-off where you eat all the R&D and procurement costs, or whether it's a large commercial enterprise
Rolls Royce is working on SMRs, small reactors, suitable for powering remote towns/villages and large single factories
they're less economically efficient than normal PWR/AGR/Gen IVs, but they overcome a big problem in nuclear finance, which is the high buy in price
in other words, you can invest in them without putting all your eggs in one basket, and it opens up nuclear investment from just government to commercial
>How large would be the area of effect?
depends on scale of reactor, means of containment, and how the contaminants are spread around which is affected by wind direction, but more so by whether you are moving the reactor around, and whether you realise it has failed
see the goiania incident, it was only so harmly because the scrappers kept taking it places
for another example here, governments do not consider a dirty domb a legitimate physical threat, it's only a psychological threat due to the radiation fear it would cause in the population

>>2785198
>You'd need a masters degree in nuclear physics.
in my opinion it's not the physics knowledge that will hold you back, reactor kinetics is hard but not prohibitive for one man to learn
the engineering capabilities and economics will be the bigger hurdles, plus the fact that as it stands you would have to make this undercover whilst you shine a big beaming light (radiation) to any government agency who cares to look
>>2785312
>I've heard that nuclear reactors give off very distinct neutrino emissions which can be picked up by watchdog satellites.
gamma yes, neutrinos no
i'm not sure if it's satellites, a plane or helicopter works just as well
>>2785572
what you will get from this is called 'low grade heat'
it's not useful for power generation, because of the carnot equation, maximum efficiency = (tHot - tCold) / tHot
so if tHot and tCold are close, the numerator is almost small, remembering that those are in kelvin
so say you had 50C waste (normal temperature for a waste barrel at the start of storage), and 25C water (it must be room tempoerature otherwise your wasting another round of efficiency on generating the power used to cool it), you would have 323K and 298K
so your efficiency is (323 - 298) / 323 = 7%, and that's your maximum
for scale, PWRs get around 40% efficiency at best, so 100% is a very high assumption even under the best of conditions
this is why AGRs and most of the Gen IVs aim for higher temperatures: higher carnot efficiency

>>2784962
you should know most of us post from phones and desktops / laptops nowadays, we aren't so poor as to only have one or the other

Post fissionable material or GTFO

>>2784959
Look up the aqueous homogeneous reactor and codyslabs uranium refining video, you will use the latter to make the former which is just a propane tank full of uranyl nitrate heavywater brine submerged in a pool. Once you have your uranium you extracted from several semi trucks worth of hi quality pitchblende ore(codys was dog shit), the main issue you will encounter is that natural uranium cannot undergo fission because the fissile isotope concentration is too low. However you can bypass this with heavy water, the reactor is a breeder type so the concentration will improve with time and you can use normal water or graphite as the moderator if you wish. To make the solution, pour nitric acid on the uranium metal powder to make the uranyl nitrate salt. Then stir it into heavy water and pour it into your tank then submerge it in a swimming pool. The water is your neutron reflector and radiation shielding, electroplating beryllium on the inside of the tank will help it if you want. Be sure to monitor the pressure, the radiation will split the heavy water into hydrogen and oxygen via radiolysis, once it does that its probably time to use a graphite moderator

>>2785976
>what you will get from this is called 'low grade heat'
Did you read my post where I said:
>each electron that follows converts all of its kinetic energy into potential energy as it moves against the electrostatic field
I'm not saying to generate power from heat, I'm saying to generate power by charging up a capacitor to 500kV.

>>2786109
Your idea is a good idea. It's called betavoltaics. Yes, it works. It isn't very efficient.
>>2785976
This is not a thermal process, so Carnot can go pound sand. Shockley and Queisser are the ones ruining the party here.

Didn't the feds raid the home of a kid in Texas that did exactly this

>>2786123
>betavoltaics
No that's shooting beta particles at photovoltaic cells. They produce a fixed amount of energy per particle, equal roughly to their bandgap. Each electron will give you maybe 1~5eV of energy, depending on the semiconductor of choice. All the rest of the electron's energy will be turned into heat, be that 3eV or 3MeV. My method has each electron giving 546keV of energy each.

My idea is the opposite of a linear accelerator, like the one in a CRT TV. Instead of a slow electron getting accelerated by an electric field, a fast electron gets decelerated by an electric field. It's mostly elastic. The work you get is equal to:
>F = q*E
>W = F•d = q*E•d
As electrons leave the centre conductor, it charges up to a positive potential. The more electrons leave, the greater this potential. At the limit, the voltage difference will be 546kV, at which point the electrons will be so slow as to be stationary when they hit the outer wall. At this voltage, the power output capacity is zero, but the thermal output is also zero. The more current you draw from this system, the further the voltage difference will be from 546kV, and the faster the electrons will be when they hit the outer shell. This speed turns into heat. Again not going to be 100% efficient, but the efficiency is only dictated by the geometry of the system, mostly of particles being absorbed by the beta source itself.

They're betavoltaics and stopped by shielding nuilt into the pacemaker.

They also make fuck all current. Someone asked the last time beta voltaic were in the news and you'd need like 150k $ worth of them to run a cellphone and it'd be a giant brick.

Too bad

>>2784979
RTG Nuclear batteries are the absolute worst type of battery for anything that needs a lot of power all the time. The problem with nuclear is that for it to work you basically pick your half life. If you want lots of power it's going to get hot as shit and blast out radiation and last not long. If you only need a trickle of power you can get away with long lasting batteries but it's like microamps and for the size you could have just gotten a silver watch battery and it will last 10 years anyway.

>>2785312
Read "The Killing Star" that's how aliens find and destroy earth (though it's not from reactors)

>>2788280
I still think there's a compromise to be made. You can get past a century half life and still get half-decent power output instead of being a retard and using carbon 14 like the diamond battery fuckos.

>>2788280
How many small, long lasting reactions are needed to achieve the power generated by one that is short lived and has lots of power?

>>2788879
Generally, double the half-life, halve the instantaneous decay rate, and hence halve the power output. Assuming decay energies are equal. Ideally you want really high-energy beta decays at a long-ish half-life, but there aren't any uranium 235 fission products with half-lives longer than 100 years but shorter than 200,000 years. Samarium 151 has a half life of 88 years, but it's a low energy emitter, and not nearly as common in nuclear waste as Strontium 90, the 24 year half-life isotope. Maybe you can use Technetium 99, but the power output would be pretty low.

>>2784959
you wouldnt be able to make it yourself but RTGs are pretty small
good luck getting plutonium or americium

Pic is a man holding a mock fuel rod from the Hanford B, an early natural uranium reactor. The real thing was "uranium" (not sure if metallic or some oxide) encased in aluminum, which would then be placed in a graphite brick. If such an assembly can reach criticality on it's own, why can't a small reactor be made with just one or a few? Not enough heat? Additional engineering problems like SCRAM, sensors, shielding, etc.?

>>2790228
Such an assembly is specifically designed to not reach criticality on its own.

Nuclear engineering is complicated. You gotta have a couple fuel rods and enough that you can keep a reaction going while you replace one and you gotta have a bunch more to slow neutrons down and then a bunch more to control the reaction quickly

>>2790242
That explains it. I'd assumed that the neutrons didn't permeate the graphite and reach other rods. Explains why it's called a "moderator" and not a "reflector", too.

In the first-ever nuclear reactor (built in a school gymnasium in Chicago with a manual labor force of football players and high-school dropouts), the complex five-part safety mechanism consisted of the following:

>An axe

>>2784959
You could build a hydrogen fusor at home.

If you're building a nuclear power plant start with a steam generator that runs on coal or oil first.

>>2784997
Not the right kind of material and you'll need to refine it into a useable form . You'll also need metric tons of smoke detectors. You might as well just buy raw uranium rock and gaseous centrifuges.

>>2785284
Nuclear boy scout didn't make a reactor, he made a neutron source.

>>2784959
I don't understand this, why bother with fission if you can have fusion power at home?

And you actually can, the sun is a huge fusion reactor. All you need are cheap solar panels to harvest this energy.

https://en.wikipedia.org/wiki/Richa<wbr>rd_Handl<br>A swedish man tried this too but he made the fatal mistake of reporting himself to the radiation safety agency, inquiring about whether or not his experiments where illegal.

Someone would try and stop you I'm sure but something like the SNAP reactor (pic related) which is cooled with NaK would be small enough... jut mind the risk of fires.

>>2784959
Unfortunately most don't really scale down well, the closest would be a kilopower reactor like what NASA has had designed for the Moon and Mars.

Yes, it's technically possible to make your own nuclear reactor. Assuming you have the capital to fund it, the engineering, physics, and electrical knowledge to construct and operate it without killing yourself and your neighbors, and the means to attain the fuel and dispose of the waste properly. However getting thrown into federal pound-me-in-the-ass prison for a long time isn't really worth doing something that might break even in cost in like 2 or 3 decades.

legal, and nuclear material aside, constructing and safely operating a nuclear reactor requires extremely precise machining, expensive, exotic materials, and destructive quality checks. this is outside the ability of one person. maybe a government funded team.

>>2792680
Solar either requires either that you only need to use power during sunny days, or that you can store energy for entire weeks of bad weather. If you're in the middle of a desert then you might only need to plan for one day of bad weather, but the rest of the world necessitates some sort of medium-term storage. You can somewhat reduce the maximum no-generation period by supplementing with wind or micro hydro, but those are also weather dependant, and you might not live somewhere with a convenient stream or enough exposure for wind generation. And small mechanical generators means more stuff to go wrong. Energy storage on this sort of scale just isn't cost effective for most cases.
Also cheap PV doesn't last that long. 20 years if you're lucky.

Lithium battery chemistries exist because they're lightweight and energy dense, which means they're much more expensive than necessary for home storage. Sodium ion cells aren't in mass adoption yet, maybe they'll have good cycle lifetimes but we've yet to see that in practice. Flow batteries require infrastructure that scales up well but probably isn't practical for homes. Thermal energy storage and molten salt/metal electrochemical storage also get more efficient at larger scales and probably don't make sense for individual homes. Lead acid doesn't last enough cycles. Compressed air is inefficient and complex.

Hydropower or making heat for a steam turbine doesn't have this problem. Not that using nuclear is particularly practical for a home either, it has a different set of problems.

>>2784959
Ultimately your problem is getting ahold of materials, or parts, rather. Nuclear material slugs, graphite moderator, boron alloy control rods, proper shielding, coolant (water) pumps. The particle physics and thermo aspects aren't so abstract that someone couldn't figure out how to build one. if you were rich and resourceful you MIGHT be able to come up with the graphite and boron steel, but good luck getting your chosen fuel. It would have to come from an enrichment facility, things don't fall off of those trucks.
The better question is could an amateur figure out how enrich a meaningful amount of material within reasonable time/cost? If you could make that a yes, then things could get pretty silly.

Small scale/Personal Reactors have the "Flying car" problem.

We had the technology to build Flying cars since the 50's. Otherwise known as "helicopter". Look at how the average person drives.... The real issue is that operating a multi ton machine in 3 dimensions over a suburb is beyond the ability of most people. Do you want Bubba crash his Modified Chopmaster 9000 Raptor cockreplacement into your kids bedroom?

Same goes for reactors. Even if technically possible, the real issue is giving "regular" people access to something as energy rich, not just for the risk of abuse or terrorism, but simply because the "average" human is incapable.

>>2797231
Nowadays, people started experimenting with self driving cars. I don’t see why people won’t try for a self operating nuclear battery/reactor.

>>2792680
That’s an entire different thread to be had
“ what would happen if the goverment issued an order to have at least 1 solar panel on every buildings’s roofs?”

At most, there would be a disscount, but it would dissappear at some point because electric companies would raise their prices to compensate

>>2786075
>Once you have your uranium you extracted from several semi trucks worth of hi quality pitchblende ore
what about the method of turning thorium into usable urannium like that boyscout did?

>>2797273
I'm not sure if this is meant to be assurance that driving is getting safer and hence nuclear reactors should be safer too, or if you're saying that people are already experimenting with dangerous shit so restricting nuclear reactors doesn't really make sense

>>2797231
there's also the issue of cost
helicopters are much, much more expensive than a car. like 100x as expensive to purchase and operate. it makes more sense to just buy a car and spend a little more time on the road than to try flying everywhere
personal nuclear reactors would have the same problem. it makes more sense to just buy (what is already extremely cheap) electricity from the power company than laying out millions of dollars to purchase and operate a one-family reactor.
on top of this, there are already technologies that will let you generate and store electricity using fossil fuels and batteries which are much safer and cheaper than nuclear power

TRIGA reactor configured to make power sounds like what you’d want, but that (particularly the fuel rod assemblies) isn’t the sort of thing you could DIY

if you wet it, until it's a bit damp, add some non toxic glue (paper glue works just fine), put the cartons in a vague mold form and repeatedly hit it with a hammer, it will stick together. if you let it dry, you have first class, long burning fire briquettes
alternatively you can store eggs in it.

>>2798430
If the measurement being obtained is how loud a sound is outside the room it's happening in, then egg crates inside the room aren't going to change that measurement very much. What they're going to be better at is dampening the high echoey noises inside the room, when measures from inside the room. Also they look cool.

>>2791602
You'd be surprised what can be reused effectively.
These can be cut into individual cups and packed with sawdust and wax for better firestarters than you can get at a store.

But you don't care about reusing things, you want to shekel out for every single thing and beg your kike masters for more things to buy.

>>2798440
So, still no explanation? How can it dampen echoes but not noise? I would have expected multiple reflections where each reflection is a little lossy would do the trick. If that were right, stacking egg cartons would improve the performance.

When the wave (the sound wave) hits the curved surface it distorts the wave making it incoherent thus unable to be heard as "an echo".

However what the egg carton does not do is significantly reduce the "amp" or energy of the wave thus there is still *background noise* that is unintelligable.


Every farmer needs a real hoe.
Sure, there's plenty of mass production brands out there at the stores.
Those work OK if you're dainty with them.
But does anyone know where one can get heirloom quality hoes?
Hoes that can take a real man working the dirt with them

Had one for like 10 years, it takes a beating no diff

No offense but fiskars ain't exactly the wrought iron forged classic hoe of yore I was hoping to find suggested here. I need something to plow true grit. The kind of soil most men would take one look at, walk 360 degrees away and never come back to if they were planning on homesteading somewhere. The kind of frozen alaskan tundra that not even a kodiak grizzly could muster a foxhole in. Preferably something hand made, from a real blacksmith forge. Thick wooden handle. No fiberglass sissification please.

>>2790307
Well when you get done larping, go get a Fiskars

>>2790313

Prohoe/rogue hoe. Made on missouri. roguehoe.com. Don't listen to the inventory warnings. Get it from an established distributor,s who can order the item you want.

Morgan County Seed is a distributor who ships and will accept cards over the phone. 573-378-2655.

Caution that USPS, which used to be cheap to ship hoes and other oblong objects, switched to dimensional weight about a year or two ago. It is a hokey system that adds weight to the calculation - if something is odd-shaped, like a hoe. Even if it only weighs ~ 5-10 lbs, e.g. their 6" wide turnip hoe has a 60" fiberglass handle (that I think you can get in ash wood), the 60J, it runs the shipping costs up.

For the 40HX42 and 100CR, one of which is 60" handle, shipping together was cheaper with UPS vs USPS, which wanted something like $68 vs $50.

The tools are well worth it though. Buy once, cry once. Their tools have a welded collar. They are meant for dealing with the ozark hard clay and rock, so anywhere else is even better.

>>2790297
honestly just buy a big block of steel (preferably tool steel or even just a decent medium carbon alloy), a plate of 4140 steel, and make a coal forge. heat the plate and hammer against the bigger block of steel until it's a hoe, dunk the tip of it in water after last heat and let the rest cool in air. take a torch and heat the tip after it cools until it's straw colored, then get a wood handle (sold everywhere) and shove it in the appropriate hole. cheap and cool like my working class balls

Numb Diggers rise up

True temper or razorback for a good forged shovel. Stamped shovels are bullshit. I also bought some good hoes from the local 2nd hand farm scrapyard place. They almost look like someone took a disk blade and wedged it up into pie sections and then welded a pipe socket onto it to accept a handle. But I think they are factory made by someone.

T. Farmer that actually uses shovels not some home gamer larping faggot.

No, I have never seen a shovel like that in the wild. Long handled forged irrigating shovels are what is popular around these parts. I suppose in different areas of the world you would find different form factors of tools preferred due to different environmental factors.

Kind of how there are a vast difference in farming techniques for different areas too depending on weather, irrigation styles, and soil types.

There is nothing on this planet that's self sharpening. It's always a gimmick.

>>2790376
Self sharpening in relation to anything that goes into the ground is a meme, sharpening with a file is a must - makes a huge difference and won't take all that long. If you really care about efficiency improvements, you could also buff off any rust and coat with wd40 to reduce friction as much as possible. Sharpening will make the biggest impact tho.

>>2790664
who the fuck sharpens a hoe
one with good steel and thin blade will not need it, and whatever edge you put on is gone the second it hits a rock
as i understand, self sharpening means it abrades the edge rather than rolling over

>>2791913
Tell us that you've never used a hoe for actual work without saying it exactly like that... When you're out chopping weeds in the summer because it's too hot to dig (trees, that is, nursery work) and you spend the last five minutes or so of lunch sharpening up from chopping all morning, that first swipe when you start back, and it just sails through some horse weed or goldenrod or something, it feels so damn good. You just feel like a real hoer.

>>2791926

>>2793488
I just use steel instead since I use my hoes harder than a Chiraq pimp. I found grounding rods with a vertical pull handle like Ames ergo rakes work great for raking thicc piles like when burning waste wood.

For a wooden handle socket cutting and splitting a section of pipe as you describe would work and to get an uninterrupted handle you could zip disc a wedge out of the pipe then heat and torch bend it together as a tapered socket.

WTF? no every farmer does not need a hoe.
>if you're dainty

>a real man working the dirt
hoes don't work in the dirt.

The one and only purpose of a hoe, is to "dainty" drag/scratch and pull up weed sprouts, once a week. You wanna dig? then get a sharp spade, You wanna peel clay?, then get an adze. Hoes don't dig or work in dirt. So get a lite weight floppy plastic hoe. who cares.

I used a few bunch when I would weed an acre of corn since we didn't herbicide and the stuff wasn't super densely packed.
Having a dull one sucks. I have thin skin and could never develop calluses, so I usually wore gloves. Wooden handles suck, but the ones we had were super cracked and old. We had one with a soft cushion covering, but those never last long. Then i've seen cheap plastic hsndles which felt like cheap compacted fiberglass, and those broke quickly.
Anyways, i suggest wrapping your handle and then it's easy to grip with gloves if you have mire strength than your skin can handle.

I just got mine from my grandparents, whenever the handle breaks i just go get another handle for it. you can find old hoe heads at local junk yards and shit idk bro a hoe is a hoe, to be honest a lot of the ones from 1930s and back are way more fragile than what you can buy at walmart today, they were trying to use as little metal as possible to keep cost down and so the "neck" or whatever you wanna call it of the hoe is usually pretty thin and the metal is typically not amazing quality.

Ok, well I can't speak for mexico or squatamala, but it's common practice by electricians on the States. Like I said it's not actually Code, it may be an insurance requirement. Does insurance vary? Yes. Do things get grandfathered in? Maybe.

>>2791465
> 'electrician'
Was the wiring upgraded to 12/2 (US, 120v AC)? If it was properly wired to begin-with, the 15 amp breaker was to protect all wiring downstream, which would have then been 14/2. If a 20 amp is now installed, then why wasn't one used originally?

99% chance that it means the wiring was not rated for it. The price is the same between a 15 amp and a 20 amp, so if it was originally wired correctly, a 20 amp breaker would have been used. Congrats - you have likely increased the chances of an electrically caused house fire.

I could be off by a little - like not considering outlet limitations. Correct me if I am, if you are at a Journeyman or higher, or equivalent.

>>2791505
technology connections tore open a 20 amp outlet and the internals were identical to a 15 amp outlet made by the same manufacturer

>>2791364
In addition to the others said, power supplies and PDUs in server/network racks sometimes use them. What bugs me more is that whoever built my house had the good sense to use all 20A circuits with proper 12AWG wiring but used the 15A outlets. I mean, it'll never be a problem but it still bugs me. I understand since you can get a whole box of the 15A receptacles for the cost of one 20A receptacle.

>>2791505
> 99% chance that it means the wiring was not rated for it.

He told me that 14ga wire was fine for a 20A fuse. When I questioned him, he literally said “look, I’m the one that passed the electricians test ok?”

It was too bad too, I really liked the guy up until that point. Oh well, home he’s not out there burning down too many homes.

>>2791526
>I understand since you can get a whole box of the 15A receptacles for the cost of one 20A receptacle
Yeah, it's cheaper and code allows it since it's rare you'll ever plug in something that draws >15 amps at a single outlet.
Be happy you got 12 gauge wiring to all your outlets at least, my company uses 14 gauge anywhere they can get away with it.

>>2791506
All the ones I have worked with are substantially heavier than a 15 amp. Maybe he bought some cheap retail shit, or didn't consider the density/strength/weight, just the looks.

They will 'look' very similar internally. i wasn't talking about that, but if you are mostly concerned with looks, I'm sure the chinese have some second-rate non-UL outlets that look the same, that they'll sell you. Your call.

>>2791547
In the circumstance, that the 20 amp breaker is on a single-outlet convenience circuit, next to the main breaker panel, hung on a wall and run through metal conduit, how I would do it, it should be 'ok'. If there was an overload condition, the wire is so short, that wire heating will be secondary to the breaker tripping. Although it won't be current Code.

> electrician test
They tend to be proud. It's experiences, though, not a test, that sets an electrician apart. That answer was something (((YOU))) can google. Who paid the electrician for his work?

>>2791592
> is on a single-outlet convenience circuit,

Haha, no just one of the two “garage” fuses. I did google it, learned about how even though 14ga is rated at 20 amp or whatever you have to fuse at 80%. Forced him to come back and swap the 20A fuses for 15. I paid him, because his job was to replace the old 15A fuses, which he did. He just thought he was doing me a solid by dropping in the 20A ones.

On one side of the plug there's a bunch of pixies all cramped up in a tight space and they wanna spread out.

On the other side there's a whole bunch of space for them, but no way to get there.

If you build a good enough bridge for the pixies, they'll do whatever it takes to get across it.

If too many pixies cross the bridge too quickly it'll heat up and catch fire.

We increase resistance to tell the pixies to slow the fuck down and take their time or someone might get hurt.

>>2791364
Yes. Continuous use power draw devices (longer than 3 hours) derate the capacity to 80%. A 15 amp circuit is only designed to run 1440W for over 3 hours even though 15A is 1800w.
20a is 2400w, or rated for continuous use of 1920w.

Its a question of if you want to use that 15a device for more than 3 hours, not if your device actually needs 20a

Error correction

I want to implement an error detecting and correcting system to keep my data perpetually.

I would need it to work through the deaths of individual drive, and I should be able to varry the amount of redundancy

It would also be great to know where there is already error correction in my data

Do y'all know any good resources, programs, etc?

Thanks

I have a similar situation. How do I know when to oil my bike chain, and what is the best oil to use?

And another question: when I was in San Francisco every restaurant served delicious sour dough bread, and since then I've searched high and low for advice on how to make sour dough bread at home. Any tips would be appreciated.

I guess OP accidentally left SQTDDTOT out, but that's fine. I bought some GE silicone sealant in the caulk tube format a year or two ago, and just got around to using it. It seemed a bit runny but otherwise ok. Now, several days later, it's as gooey and runny as it was the first day. I did my entire bathroom, so please tell me it's going to cure eventually and I don't have to clean it all up. THANKS!

>>2791587
>I would need it to work through the deaths of individual drive, and I should be able to varry the amount of redundancy
What you want is a RAID array on a NAS. Depending on your needs and cost restraints you will need to pick a raid level (see picrel)
Raid is only one part of keeping data perpetually, and should follow a 3-2-1 backup plan:
3 copies of your data
2 Different storage media (HD + Disc, HD + Tape, HD + SSD, etc)
1 copy off-prem (Stored in separate physical location to avoid catastrophe like fires or floods

Error correction is built into plenty of filetypes, but data should probably be re-written every 2-3 years on a hard drive to meet industry best-practices. there are drive cloning tools you can use to do this (I use Clonezilla). Obviously you need two disks if you are using cloning to rewrite your data periodically. IMO, many people have had data on hard drives for decades, but your risk tolerance is up to you. If you are okay with your data being non-ready you could always archive them with 7zip or winRAR. The compression algorithms have built in error correction on decompression, but obviously if you want to use the files you would need to decompress it.

I hope that helps. People love to scream that physical media is dead, but if you're looking for long term storage and don't mind paying a bit, you can always get a used LTO5 drive and write 1.5tb per tape. Those data tapes are still used for a reason- if stored well and kept in a controlled environment, they will last 30+ years. Biggest problem with tape is that the read/write hardware is often hundreds and hundreds of dollars, even used.

Let me know if you need me to elaborate on anything. this might be a better question for >>>/g/

traditional bread has the starter formed from what's in the environment. Look up grape rust. That's how san francisco sourdough got started. It's the same if you could tour over france a hundred years ago; variation, and deep flavor. With the advent of quick yeast, an engineered yeast that rises very quickly, it does not properly interact with the dough, to properly pre-digest it. Like a meat chicken, it's a frankenyeast.

You can buy san fran sourdough yeast. But it's not the same as what would have been naturally occuring throughout the region. Look into something like friendship bread, where the starter is handed-down through multiple people over an extended period of time.

>>2792487
Are you autistic? When people are talking about backing up data on physical media they're 99% talking about making disks or tape backups- things you control. Of course cloud storage uses physical media but from a data backup plan perspective it's not physical media controlled by you, it's hosted storage governed by whatever cloud storage provider you want's SLA. That's like arguing "What do you mean you're going to take an uber home from the bar? SOMEONE is driving!" you fucking retard.

take a look at snapraid
it gives you a lot of control over parity
it can mix different sized hdds
common raid systems like raid5 are focused more on availability (server does not go down) than on reliablity

so here is the thing, if you look into this the real problem isn't the degradation of your data it is the loss of encryption type. there are already image types that can no longer be decoded because variations on .jpg have gone defunct. it will happen to .jpg, it already is with .webp. kids these days don't know .gif was the o.g. transparent image. a dozen other formats have been lost. did you know there was a .jif image format? document types, images, movies - they will go the way of flash programs before your data degrades so what the fuck is the point?

Say I wanted to get into using microfilm, what would be the entry cost?
Is this medium compatible with error correction software?

I'm guessing you'd want a reader too considering you'd need to verify the setup and clarity of the result. $200 isn't awful tho, not sure about film costs.

>I want to implement an error detecting and correcting system to keep my data perpetually.
The only thing that comes into my mind is what NASA did to stop computer memories in space from flipping bits due to cosmic radiation, which is just relying on parallelism by building 4 computers checking each others. If one goes nuts, the others take control and correct the errors. They avoided 160 bit flips with this and kept stuff operational.

So you could just do something like a RAID-1, copy the same file on more memory devices, and check the integrity of each bit against its counterparts on other drives. If one bit is 0 but you have 10 registers telling you said bit should be 1, you can recognize it's an error.

Microfilm is not film like data tape, it's a physical photograph of whatever you want to capture, but stored on very very small (Micro, if you'd believe it) film slides. You can then use a special projector to view the microfilm. It's an entirely analog medium and it was created to store large volumes of print information in less space, before digital was even a thing. Each microfilm slide is 1/25th the size of whatever the source material is, so if you have 25 sheets of paper, it will take up about the same space as 1 sheet which was pretty good back in the day.

I have a Dell R620 server, it has 10 SSD drives in a RAID60 configuration. when a drive goes bad it starts flashing the R/W light, I pull it and replace with one of the spares I have on hand.

>>2797649
How much does this setup cost? Isn't having to change entire SSDs every time there's an error wasteful?
Is this even error correction?

>>2797892
Nta but I have a similar setup for my nas except it’s different hardware and a lot more drives with a mix of ssd and spinning drives. Oversimplification but the error is not just like “oh there was a teeny issue” it’s like “oh the drive is on its way out” and you pull it from the array and replace it so it’s contents can be rebuilt. It’s not a backup solution because sometimes the rebuild process reveals that 3 more drives were about to die as well and then the whole array is fucked but that’s not super common

>>2791587
ZFS.
You can set it up so it will constantly scrub the data and fix any errors as they appear. Look into it, it's basically what everyone in this thread is trying to re-invent.
