Why Sewer Ejector Pumps Can Fail Sooner.

After conducting a thorough investigation into the premature failure of sewer ejector pumps, several key factors have emerged that explain why these pumps might break down sooner than the manufacturer's warranty period:

Improper Installation.

One of the leading causes of early pump failure is improper installation. If the pump is not installed according to the manufacturer’s specifications—such as incorrect pipe sizing, inadequate venting, or poor alignment—this can cause strain on the motor and moving parts, leading to accelerated wear and tear.

Power Surges and Electrical Issues.

Power surges or fluctuations in the electrical supply can damage sensitive components within the pump, such as the motor or control panel. Even if the surge lasts only a second, it can burn out circuits or compromise the motor's efficiency. Without surge protectors or proper grounding, this can lead to premature failure.

Clogs from Improper Materials. Sewer ejector pumps are designed to handle waste and certain types of debris, but when improper materials—such as feminine hygiene products, wipes labeled as "flushable," or other non-degradable items—are flushed, they can clog or damage the pump. Over time, these clogs can cause the motor to overwork, leading to an early breakdown.

Lack of Regular Maintenance. Routine maintenance is often overlooked. Failing to check and service the pump periodically can result in small issues going unnoticed until they become larger, irreversible problems. Sediment buildup, worn-out seals, or deteriorating gaskets can all contribute to pump failure, especially in areas with hard water where mineral deposits may accumulate.

Overworking the Pump.

Many sewer ejector pumps are not designed to run continuously. If the pump is overworked due to improper sizing, such as being undersized for the household’s waste output or running too frequently, it can result in overheating and breakdown. Ensuring the pump is appropriate for the expected load is essential for longevity.

Environmental Factors.

Harsh environmental conditions such as excessive moisture, flooding, or extreme temperatures can affect the pump’s lifespan. Excessive moisture can cause corrosion of internal components, while extreme cold or heat can affect the motor and seals. Additionally, if the pump is exposed to corrosive chemicals or gases in the sewage, it can degrade faster than expected.

In most cases, premature failure of sewer ejector pumps can be traced to installation errors, misuse, or lack of maintenance. To ensure a pump reaches its full lifespan, it is critical to follow manufacturer guidelines, perform regular maintenance, and avoid flushing materials that can cause clogs. These preventative measures can help avoid costly repairs and ensure the pump functions efficiently for its intended lifespan.

Ok so you're looking at the aftermath of Helene and you're thinking "shit, how would I keep my phone charged? What about my neighbors?" and you have some outdoor space and some cash. Your friendly formerly off grid sheep farmer is here to help.

You need this set up right here:

To that you will need to add:

Y connectors:

The 100aH (amp Hour) deep cycle battery of your choice - lead acid AGM will be cheaper, lithium (LiFePo) is more expensive but lasts much longer.

Finally, you need a small pure sine wave inverter like this one: https://a.co/d/70vRd79

Plug the panels into the Y connectors then into the single wire to run to the charge controller. They are now connected in parallel. Take them outside to a sunny spot and face them south and prop them up at about a 45 degree angle. This isn't perfect but it will be good enough.

Connect your battery and charge controller. Connect the panels to the charge controller. All of the places to do this are labeled and all you need is a Phillips screwdriver. I recommend doing it once in a non-disaster situation so you know you can do it but you'll be fine. Boom, you are getting electricity from the sun!

The inverter draws power even when it's not running so don't leave it hooked up when you're not using it. When someone needs to charge their phone, put those alligator clips on the matching color battery posts, turn the inverter on, and plug in the phone/radio. Voilà! A single 100aH battery is not going to run a bunch of things but it will help keep cell phones charged without using up the gas in your car.

The panels are weatherproof but everything else needs to be protected by the way so you'll need to set this up in a shed or garage or in the house. Lead acid batteries can produce hydrogen gas when being charged but just having one isn't a big risk.

FAQ:

Yes, you can permanently mount the panels to your roof if you own your home etc. They're designed for that!

It is true that places sell "solar generators" - those are a charge controller, battery, and an inverter in one box at a very high price point. When a component goes bad you will be unable to replace the component and must replace the entire $1000 box. They are also not upgradeable or expandable, this is.

You do not have to buy Renogy, I recommend them because they kept me in electricity for the years I was off grid.

You do not have to buy the kit, you can buy the components of it as and when you can afford them!

Remember to keep your battery on a trickle charger.

We urgently need to move away from fossil fuels, but electric vehicles and other green technology can put their own pressures on the environment. That pressure could be eased with a new magnet design, free from rare-earth metals, that was built with AI in just three months. Rare-earth metals are essential components in modern-day gadgets and electric tech – including cars, wind turbines, and solar panels – but getting them out of the ground costs a lot in terms of money, energy, and environmental impact. As a result, technology that doesn't use these metals can help us transition towards a greener future more quickly. Enter UK company Materials Nexus, which has used its bespoke AI platform to create MagNex, a permanent magnet requiring no rare-earth metals.

i think… when this nightmare is over, i’d like to be a machine. i’d like to feel my circuit boards flicker, my hard drives and cooling fans spinning, my LED trim lights glow as I come to. i’d like to lift my hand up, still humanlike, and to touch my face, hear the soft clunk of my polished vinyl fingers against the soft rubbery cladding of my cheek. I want to feel the resistance of my joints in their sockets, tap my eyes and feel the glass. I want to feel my inner workings flash with electrical pulses while the light bounces off of my plastic skin. I want to be able to read the stencilled barcodes and warnings and legal information off of my body panels. I want to feel my humanoid form, but in a way that is noticeably and profoundly not human.

but most of all I want someone to love me for it. I want them to adore every inch of my high precision cut steel & PVC components, so that when I need to be repairs they can tenderly take a screwdriver to the gleaming fasteners holding my faceplate and stomach panel in place. And they can take them off, and see my inner assemblies. And they can fall in love with them. They can be so infatuated with my reality that they can’t help themselves, grabbing my plastic crotch, wrapping their other arm around my neck and propping up my limp head so they can sloppily kiss me in my exposed mouth assembly. And I can feel their weight on mine. And as their mind is filled with desire for me they will get more aggressive towards my frame, grabbing my wrists by the joint, lifting them up and tightening their grip until i feel it crack and crumble in their palm. and they can bend my arm backwards, and pull as hard as they want, until my shoulder joint gives way entirely and the torn wires and hydraulic hoses spill from my sides. And if they are really that attached to me, they will keep making love with me until their saliva and cum mixes with my leaking coolant and hydraulic fluid, and their overwhelming love for me will crush down on my circuit boards until they crack, and I will lose conciousness from a Fatal Error Exception. Only then will I feel complete.

all the fearmongering about nuclear is fucking insane if literally any of the alternatives are looked at. ignoring the fact that, in the real world, stopping nuclear expansion literally only leads to more coal plants being built, the only other alternative is 'renewables', which, in order to provide enough energy to actually power the world, would entail a 400% increase in global resource extraction to supply the rare earth metals for electrical components, basic materials for construction of millions upon millions of turbines and panels, and etc for their infrastructure. 'nuclear requires resource extraction' - so does literally everything, and nuclear requires far less of it than any alternative.

HAI HAI HAI HAI!!!

I followed your rbg Trio blog, and ur art there is so So cute!!!

And I wanna know more about your 'robot boombox' au cus I'm curious and honestly, that headcanon is so real for boom!

EEEEK HAII ^_^

tyuu eueu... it means alot :3

so uhhh robot boombox au is pretty much just in my brain, i havent posted abt it or anything. but ive got vague ideas about it!

im gonna put bullet points under the cut in no particular order, cause again, this is mostly just concepts, so expect a bunch of yapping

in this au boombox would be created by someone, and was made to be a sort of 'testing device' for a manufactured gear (his boombox). while also being a sort of artificial life based on mimicry.

(note, i am not well versed in robotics stuff, if something seems stupid uhhh whoops)

i havent come up with a creator or creators, but they made him with the intent of seeing if they could basically make an artificial demon that could get along with other demons well! (thats where his creators got the idea to make him a dj, or a glorified mp3 player came from.)

hes entirely mechanical, his power source is through electrical charging. he charges often, which comes across as him sleeping often.

i imagine him with a charger tail that can also somewhat extend.

his visor is literally attached to his face and would be more emotive than regular boombox phighting

i imagine he got let out to interact with other demons, he was given a lot of carefully monitored data, and even now seeks out ways to be more empathetic, and to be responsive to others emotions and to help them.

he doesnt become evil or anything like that

his 'skin' would be some kind of rubber or latex, used to protect internal components and appear more demon-like.

he has two speakers imbedded in his chest, and in the rubber skin there'd be mesh to let sound travel clearer, which happen to look like top scars ( :P )

in place of where a human heart would be, he has an internal metronome, which he can set the tempo of. it can also be heard if youre super close, like a faux heartbeat.

his horns work as a secondary charging method throughout the day, acting like low powered solar panels, (like the ones youd find on calculators).

his horns take in uv light and convert it to energy. amd they are covered with a transparent solid material (imagine something like resin) to give the appearance of a normal demons horn. however this means charging through his tail is much more optimal than the passive uv charging.

has a database in his torso containing specifically music knowledge. audio can be downloaded to there and sorted and dissected to make him work better and understand the tastes of demons

in his heads a mini computer.

his mouth is a simple metal open close rectangle shape, with small components that either make the faux-skin sides of his mouth pull up (to make a smile) or down (to make a frown)

also in this au rgb trio still a thing because i am insane abt them

i imagine skate and sling learn that boombox is a robot, but they still care for him and treat him the same as before

he doesnt 'feel' anything in a person sense, and he hasnt gained sentience or anything. his programming makes it so he's drawn to other demons, and wants to make them happy. and in return, he feels 'happy' when he accomplishes that.

he learns about friends and other relationships and such, and if he has a few people he's especially close to that he can make happy just by being around, it means he's achieving his goal.

so he does have favorites, mostly because he learned that demons tend to have favorite people, and therefore replicated that behavior

he's in a qpr with skate and sling, who r both dating eachother, theyre all very affectionate.

sometimes if he gets too many positive inputs at a time, you can hear his fans running quicker (like, example, his partners are being super sweet to him, verbally or physically.

he doesnt know who made him, nor really cares to find out

when he was made, he was given the knowledge of about a 17 year old, and the mentality of one. he counts his birthdays as aging, being currently 23.

sometimes when him, sling and skate are sleeping together, he'll play calming music directly from himself.

he doesnt sleep, but shuts off non-essential components and kind of pretends to sleep while charging. since he has to be plugged into a socket of sorts. usually during that mode hes sorting any files, or things he's collected. throughout the day

sling and skate dont know that he isnt actually sleeping, and think he's just powered off

his gear works as youd expect, able to play music and use its abilities. he's just also able to directly play music from his body

when being created, he was made first, and the idea of an artificial gear came second. which is why theres overlapping abilities that may seem redundant.

his creators are no longer alive

his creators were from playground

he would likely be 'killed' for having an artificial gear and used for parts if certain people knew (the law)

and heres some silly sketches i made in class awhiiile ago (note again that i do not make robotics or know pretty much anything abt them. im just having fun ^^')

i yapped alot, but if you have any specific questions, put them in my askbox and ill happily answer! -w-

A way to recover silver from dead solar panels with 98% efficiency

A multi-institutional team of chemists, metallurgists and engineers has developed a highly efficient way to retrieve silver from dead solar panels. Their paper is published in Environmental Technology & Innovation. As climate change progresses, scientists seek to replace fossil fuels with renewable resources, including solar power. But the development of these technologies has led to new environmental problems, such as what to do with solar panels after their useful life expires. Prior research has shown that some solar panel components are relatively easy to recycle, including the iron, steel and aluminum used to make brackets, racks and other support systems. Unfortunately, other components are more challenging to recover, such as the silver used in electrical circuits—it must be separated from the circuitry and the copper that is almost always present. Thus, these materials are seldom recycled. In this new study, a team in Italy developed a relatively inexpensive way to recover the silver used in solar panels.

U.S. and European officials are growing increasingly concerned about China’s accelerated push into the production of older-generation semiconductors and are debating new strategies to contain the country’s expansion. President Joe Biden implemented broad controls over China’s ability to secure the kind of advanced chips that power artificial-intelligence models and military applications. But Beijing responded by pouring billions into factories for the so-called legacy chips that haven’t been banned. Such chips are still essential throughout the global economy, critical components for everything from smartphones and electric vehicles to military hardware.

That’s sparked fresh fears about China’s potential influence and triggered talks of further reining in the Asian nation, according to people familiar with the matter, who asked not to be identified because the deliberations are private. The U.S. is determined to prevent chips from becoming a point of leverage for China, the people said.

Commerce Secretary Gina Raimondo alluded to the problem during a panel discussion last week at the American Enterprise Institute. “The amount of money that China is pouring into subsidizing what will be an excess capacity of mature chips and legacy chips—that’s a problem that we need to be thinking about and working with our allies to get ahead of,” she said.[...]

Legacy chips are typically considered those made with 28-nm equipment or above, technology introduced more than a decade ago. Senior E.U. and U.S. officials are concerned about Beijing’s drive to dominate this market for both economic and security reasons, the people said. They worry Chinese companies could dump their legacy chips on global markets in the future, driving foreign rivals out of business like in the solar industry, they said.[...]

domestic producers may be reluctant to invest in facilities that will have to compete with heavily subsidized Chinese plants. [...]

“The United States and its partners should be on guard to mitigate nonmarket behavior by China’s emerging semiconductor firms,”

While the U.S. rules introduced last October slowed down China’s development of advanced chipmaking capabilities, they left largely untouched [sic] the country’s ability to use techniques older than 14-nanometers. That has led Chinese firms to construct new plants faster than anywhere else in the world. They are forecast to build 26 fabs through 2026 that use 200-millimeter and 300-mm wafers, according to the trade group SEMI. That compares with 16 fabs for the Americas.

So what's the problem? is it that you suck at manufacturing & want more neoliberalism? That's what it seems like to me [31 Jul 23]

SPOTLIGHT ON: Murderbot Fanimation Project Backgrounds!

(Part 3 of 3) (Jump to part [1] [2])

They may be the literal background of the finished product, but the backgrounds done for the Murderbot Diaries Fanimation Project deserve their time in the spotlight!

Part of what makes the Fanimation stand out as much as it does is the love, care, and attention to detail that the artists poured into the backgrounds. The team stuck closely to the source texts when designing the spaces, producing some beautiful pieces of art that deserve appreciation on their own.

You can watch the Murderbot Diaries Fanimation Project here.

In this final part, we look at some of the backgrounds that we animated to give them that extra wow factor. Some of the shots in the Murderbot Fanimation have backgrounds completely made in 3D - the opening shot and the post-credits scene, for example. But the shots in this post are mostly 2D imagery, with some 3D components and clever editing that bring them to life.

[In February, 2023], a small warehouse in the English city of Nottingham received the crucial final components for a project that leverages the power of used EV batteries to create a new kind of circular economy.

Inside, city authorities have installed 40 two-way electric vehicle chargers that are connected to solar panels and a pioneering battery energy storage system, which will together power a number of on-site facilities and a fleet of 200 municipal vehicles while simultaneously helping to decarbonize the UK’s electrical grid.

Each day Nottingham will send a combination of solar-generated energy — and whatever is left in the vehicles after the day’s use — from its storage devices into the national grid.  The so-called “vehicle to grid” chargers deliver this energy just when it’s needed most, during peak evening demand, when people are home cooking, using hot water or watching TV. Later, the same chargers pull energy from the grid to recharge the vehicles in the wee hours of the night, when folks are sleeping and electricity is cheaper and plentiful.

“We are trying to create a virtual power station,” says Steve Cornes, Nottingham City Council’s Technical Lead. “The solar power and battery storage will help us operate independently and outside of peak times, making our system more resilient and reducing stress on the national grid. We could even make a profit.” ...

After around a decade, an EV battery no longer provides sufficient performance for car journeys. However, they still can retain up to 80 percent of their original capacity, and with this great remaining power comes great reusability.

“As the batteries degrade, they lose their usefulness for vehicles,” says Matthew Lumsden, chairman of Connected Energy. “But batteries can be used for so many other things, and to not do so results in waste and more mining of natural resources.”

The E-STOR hubs come in the form of 20-foot modular containers, each one packed with 24 repurposed EV batteries from Renault cars. Each hub can provide up to 300kW of power, enough to provide energy to dozens of homes. One study by Lancaster University, commissioned by Connected Energy, calculated that a second life battery system saved 450 tons of CO2 per MWh over its lifetime...

Battery repurposing and recycling is set to play a massive role over the coming years as the automobile industry attempts to decarbonize and the world more broadly attempts to fight waste. The production of EVs, which use lithium-ion batteries, is accelerating. Tesla, for example, is aiming to sell 20 million EVs per year by 2030 — more than 13 times the current level. In turn, 12 million tons of EV batteries could become available for reuse by 2030, according to one estimate.

“Over the next decade we are going to see this gigantic wave,” says Jessica Dunn, a senior analyst at the Union of Concerned Scientists. “Companies are recognizing this is a necessary industry. They need to ramp up infrastructure for recycling and reuse.”

New research has found that 4,642 species of vertebrates are threatened by mineral extraction around the world through mining and quarrying, and drilling for oil and gas. Mining activity coincides with the world's most valuable biodiversity hotspots, which contain a hyper-diversity of species and unique habitats found nowhere else on Earth. The biggest risk to species comes from mining for materials fundamental to our transition to clean energy, such as lithium and cobalt—both essential components of solar panels, wind turbines and electric cars.

The Best News of Last Week - February 13, 2023

Hello there! Welcome to another edition of ‘Feel Good Newsletter’. I'm so glad you're here. Every week, I scour the web for the most uplifting and heartwarming stories to bring you a little bit of joy and inspiration. So, sit back, relax, and let's dive in!

1. Minnesota House passes "universal" school meals, providing free breakfast, lunch to students

The Minnesota House of Representatives is considering a bill that would provide universal school meals to all students in the state, regardless of their families' ability to pay. The goal of the bill is to ensure that all students have access to nutritious meals and are better equipped to learn in the classroom.

If the bill is approved, Minnesota would become the second state in the country, after California, to offer universal school meals. The bill has the support of education and anti-hunger advocates, who argue that it would help to address food insecurity and improve student health and academic performance.

2. Ukraine succeeds in bringing back 128 children forcibly removed to Russia

Ukraine has succeeded in bringing back 128 children forcibly taken by the invaders to Russia.

Source: Yuliia Usenko, Head of the Department for the Protection of the Interests of Children and Combating Violence of the Prosecutor General's Office of Ukraine, quoted by Ukrinform

Quote: "We have managed to bring 128 children back to Ukraine. More than 50 of them, together with their parents or guardians, are currently in EU countries.

3. Putting solar panels in grazing fields is good for sheep

A study found that installing solar panels in grazing fields is beneficial for sheep. The study was conducted in the UK and found that sheep were more likely to spend time in areas with solar panels than in areas without. This is because the panels provide shade and shelter from the sun, wind, and rain.

The researchers believe that this could help to improve the welfare of sheep, as they are more likely to seek out shade in hot weather, which can reduce the risk of heat stress. The study also found that the solar panels had little impact on the growth and health of the grass, which is important for the sheep's diet.

4. Dad takes toddler son for a manicure after teacher says it's 'only for girls'

The father and son were at a "Daddy and Me" event, where fathers were encouraged to spend time with their children doing various activities. The father chose to take his son to get a manicure, but was told by the teacher in charge of the activity that it was only for girls. The father was reportedly surprised and upset by the teacher's statement, as he felt that it was important for his son to be able to express himself however he wants, without gender stereotypes getting in the way.

The article notes that the incident highlights the ongoing issue of gender stereotypes and the importance of promoting gender equality and inclusivity, especially in children's activities.

4. More than half of new U.S. electric-generating capacity in 2023 will be solar, and only 14% will be using fossil fuels

Information Administration (EIA), energy production in the country increased for the fourth consecutive week. The EIA data showed that the output of oil, natural gas, and coal rose by 1.6%, 2.2%, and 3.2% respectively. The increase in energy production is due to a combination of factors, including improved drilling techniques, favorable weather conditions, and rising global demand for energy.

5. Deforestation in Brazil falls by 60% in first month under Lula

Deforestation in the Amazon rainforest in Brazil fell for the first time this year, according to a report by Reuters. The decrease is attributed to increased enforcement of environmental regulations and increased monitoring of illegal logging activities. The Brazilian government has implemented several measures to reduce deforestation and preserve the Amazon rainforest, which is a critical component of the global ecosystem.

6. Cat returned to NJ shelter for being 'too affectionate' now happy in his new home

A cat named Bruno surrendered to a shelter in New Jersey and was eventually adopted by a new family. Bruno, who was described as a friendly and affectionate cat, is now happily settling into his new home. The story of Bruno's adoption serves as a reminder of the importance of animal shelters and the work they do to find loving homes for abandoned pets.

7. A doggy day care was on fire. Neighbors helped save all 115 dogs inside.

A fire broke out at a doggy daycare and resort in Seattle, causing significant damage to the building. No dogs or employees were injured in the fire, but several dogs had to be temporarily relocated to other facilities. The cause of the fire is under investigation, and the resort is working to make repairs and get back to serving the community's four-legged friends as soon as possible.
