You know, sometimes I’m grateful that my first summer in my graduate lab, at the impressionable age of 22, my main assignment was to design and build a full closed-loop water cooling system, with a chiller whose heat exchanger had to also be connected to the building cold water system (which, if you screwed it up, had enough water flow that you could flood the whole lab). And I gained familiarity with all the main types of hose, tube, and pipe connectors and how to install them.

I also learned the very important life lesson of, if all else fails, a blow torch can solve nearly any problem. I think I solved three different problems with a blow torch that summer.

No home plumbing I might undertake will match the disasters I ran into that summer.

Demystifying Mechanical Seals: A Comprehensive Guide

Welcome to our blog, where we delve into the intricate world of mechanical seals. If you've ever wondered what exactly a mechanical seal is and how it functions, you've come to the right place. In this guide, we'll break down the basics, explore the importance of mechanical seals, and shed light on Omega Seals Company's role in this crucial industry.

What is a Mechanical Seal?

Let's start with the fundamentals. A mechanical seal is a device used to prevent fluid leakage between two mating surfaces in a mechanical system. These surfaces can be rotating or stationary, and the seal is typically installed in equipment such as pumps, compressors, and agitators where the containment of fluids is essential. Mechanical seals provide a higher level of sealing compared to traditional packing seals, offering greater efficiency and reliability.

How Do Mechanical Seals Work?

Understanding the workings of a mechanical seal is key to appreciating its significance. Essentially, a mechanical seal consists of two primary components: a rotating element (typically attached to a shaft) and a stationary element (housed within the equipment). These elements are held together under mechanical pressure to create a tight seal. The seal faces, usually made of materials like carbon, ceramic, or silicon carbide, come into contact to prevent fluid leakage. Additionally, a secondary sealing mechanism, such as an elastomer O-ring, provides further protection against leakage.

Importance of Mechanical Seals:

Mechanical seals play a critical role in various industries, including oil and gas, chemical processing, pharmaceuticals, and wastewater treatment. Their ability to withstand high pressures, temperatures, and corrosive environments makes them indispensable in ensuring the safe and efficient operation of equipment. By preventing leaks and contamination, mechanical seals help maintain product quality, minimize downtime, and enhance workplace safety.

here's what I've learned to never pay full price for, because people are giving these items away for free or almost free on Craigslist, Nextdoor, Facebook, at Goodwill, and on eBay (which has a local pickup section) in every sufficiently populated location in the USA.

cost of acquiring these items ranges from "carrying it home from the sidewalk" to "getting a friend with a car to help you pick it up" which is the same amount of effort as going to IKEA for worse quality that costs more, with the notable exception of it being a pain in the ass to coordinate with craigslist sellers, and you often have to wait and watch for what you want to actually show up. it took me about a year to find an acceptable gamer chair left out on the sidewalk, for example. but they cost $100+ new, so I chose to wait.

a lot of this stuff is the kind of thing you don't necessarily intend to keep, just to use in transitional housing or until you can afford a better one.

1. printers of any kind. basic office inkjets are free. ink is easily refillable or has generic ink cartridges way cheaper than brand name for any inkjet up to about 2015, not sure how difficult the newer smart printers are to hack but there's no reason to own a newer one because printing technology has not improved since about 2005. you want a color laser for making zines and wheatpastes? it's on Craigslist RN and someone's mom is desperate to get rid of it

2. bedframes

3. desks

4. tables

5. chairs

6. bookshelves, nice oak bookshelves that don't bend like al dente spaghetti when you put books on them, are rotting on sidewalks rn because they didn't fit in someone's house. go get them

7. scanners. I find a working scanner by a dumpster at least once a quarter, and I don't pick them up because I already have one that I picked up from a dumpster years ago

8. hot tubs. everyone thinks they want a hot tub and that the maintenance and upkeep will be worth it, and they are wrong. Craigslist.

9. sofas, with the caveat that if you are in a bedbug region like New York State you need to be very confident in your bedbug screening skills

10. quality leather shoes. these last forever and are expensive new. eBay is best for these

11. plates, glassware, silverware. all of these are able to be sterilized to whatever standard you feel comfortable with but if you eat in restaurants you've already put a fork in your mouth that hundreds of people have drooled on so try not to fool yourself

12. televisions and computer monitors

13. houseplants. similar to the bedbug warning above, you need to screen these for pests like fungus gnats and mealybugs

14. dressers, wardrobes, china hutches, cabinets, chests of drawers, etc

15. mirrors

16. clothes hangers

17. moving boxes

18. mattresses to a certain extent. I don't like secondhand used mattresses but unstained, unused mattresses are surprisingly common, especially since the foam mail order mattress boom started and people keep getting told by the mattress companies to just get rid of/keep any mattresses they want to return for flaws or wrong sizes or whatever. bedbug warning on this obviously

19. sheets and towels. you gotta launder them obviously

20. basic clothing, especially for kids. normie type clothing is so numerous people often just throw them away because they can't get anyone to take them

21. kitchenware like cooking utensils and pots n pans. don't use chipped or scratched Teflon/nonstick if you can help it. everyone needs one basic steel chef knife, which can be sharpened and maintained indefinitely. people throw these away CONSTANTLY

22. household consumables like laundry soap and dish soap. people often accidentally buy the wrong brand, scent, or develop allergies and want to get rid of extra

23. pet supplies like collars, leashes, dog crates, litter boxes, litter itself, dog beds, toys, carriers, etc

24. medical equipment of all kinds. people who take care of all kinds of patients end up with tons of leftover, sealed, miscellaneous stuff when that person recovers or dies, and they often give it away. adult diapers, hospital beds, IV stands, crutches, walkers, wheelchairs, fracture boots and splints, knee braces, canes, catheter packs, ice packs, heat packs, sterile paper sheeting, gauze, slings, over-the-door stretching and rehab pulleys, mattress protectors, etc

25. washers and dryers, both the basic household cube type and the small twin tub or rock tumbler type. people upgrade these when the old ones are still working, just squeaky or a little weird or sometimes just old

26. vacuum cleaners. secondhand ones are sort of icky but you can get rid of the ickiness by wiping them down with a rag and isopropyl alcohol inside and out. use an exacto or utility knife to slice off the hair and string wrapped around the roller. buy a new filter on Amazon. people throw away vacuums that work perfectly all the time because they don't actually know how to clean them out or do maintenance. bedbug and pet hair warning obviously

27. microwaves

28. refrigerators

30. lamps

31. any kind of exercise equipment including stationary bikes, ellipticals and weights/weight benches

32. any kind of piano. there's a grand on my local Craigslist for free rn

33. scrap wood and lumber

34. pallets

35. wood shipping crates

36. newborn, toddler and baby equipment like breast milk pumps and storage, bottles, bottle racks, diapers, etc. anything a little guy will grow out of fast will end up being given away

37. air conditioners, humidifiers and dehumidifiers. these will be most numerous during their respective off seasons

list updated 2/13/24 based on recent Craigslist trawling

38. jars, both canning type jars and clean food jars like from pickled or jelly bought at the store

39. rugs. most of my rugs are sidewalk finds. rugs will almost always be dirty. a decent consumer grade rug cleaner costs under $100, it's cheaper to just buy one if you have the space to store it. flushing the scavenged rug with soap, hot water, vinegar, alcohol, etc will clean almost anything but huge bedbug and allergen warning on this item

I was a scientist and engineer for DuPont's and General Motors' Missouri-based industrial chemical development brand Kinetic Chemicals, Inc (officially dissolved, though really spiritually reformed with the founding of Chemours in 2015) when Teflon™ was being modified for use as a potential coating in pipes in certain government projects I can't name. Now, these pipes were conveying depleted uranium hexafluoride; uranium waste produces highly corrosive uranyl and hydrogen fluorides when exposed to moist air (those Tennessee summers at Oak Ridge got pretty damn moist), so those naughty little tubes needed something slick to help everything wash down alright. It was a miserable success -- I mean it only takes a single mistake in a diagnostic test before before you can't hold up a Geiger counter to the foreman without getting a headache. Miss that poor guy, strokes are awful. So are radiation burns. Anyway, turns out some of the refrigeration units next door to the employee lounge were leaking Freon™ we were producing (see McCaffrey v. Kinetic Chemicals, Inc for more). Being in the summery youth of our scientific careers we naively sealed those babies up with some experimental Teflon™ spray, and long story short that little bit of polytetrafluoroethylene made it into every water cooler and sink on campus, both above- and underground. Forgot where I was going with this, but moral of the story is kids these days can handle a little microplastic.

I know you don't like Twitter, and I'm not sure how much of this has leaked into the mainstream, but Republicans are *freaking out* because gas stoves aren't all that healthy for kids and aren't great for the environment. And obviously electric stoves are terrible. Someone started talking about induction burners, and isn't that what you use? Or did once? Does it work really well? Or was it just better than what you had?

Yep, when I moved out of my old place (gas stove) and into my new place (elderly electric stove in a much smaller kitchen) I bought an induction burner and set it up. FWIW, Republicans are not the only ones freaking out -- pretty much every news outlet I've seen has covered the issue, some ongoing for weeks now. So it behooves us to talk about alternatives!

Point to know: the study found that gas stoves are dangerous because they tend to leak significant parts per million into the air when not turned on -- ie, they don’t have good seals against leakage when they aren’t in operation. In a well-ventilated home this is not a huge deal, but it’s still not great. What this means is that simply buying and using an induction burner instead of your gas stove is not a solution -- you need to have the gas line capped and/or gas turned off completely, in order to solve the issue.

Anyway, you can get a full induction stovetop (they're not cheap) and I've never worked with those, but the more common setup is a single induction burner that plugs into the wall, basically like a hot plate, but with the control, heat, and speed of a gas burner. That's what I have; I'm on my second, since my first wore out. They run about $40-$100 for a single burner. I got a decent one from Ikea of all places. When not in use, I hang it on a hook on the wall to make counter space, which is nice. 

Induction burners do not in themselves get hot; they use magnetism to heat the pan sitting on them, which does get hot. Food cooks at roughly the same speed as it would on a gas stove, and you can control the heat in much the same way, although most induction burners have a digital touchpad where you raise or lower the temperature rather than a knob. The single burners can be a bit noisy -- “have to turn my podcast up while cooking” noisy though, not like “jet engine” noisy. 

I don't really understand how they function other than “magnets are involved”. The downside of an induction burner is that there are limits to the pans you can use. The pan has to be made of a metal that is reactive to magnets -- so I can't use my lovely spun aluminum pans or the ceramic pans I have, and most nonstick pans don't work (teflon's bad for you anyway but sometimes you just need a damn nonstick pan). If you have an induction range or want to cook on an induction burner you need to take a magnet with you if you shop for pans, because if the magnet won't stick the pan won't work on the burner. Cast iron does work on induction burners, as do most steel and steel-clad pans.

I love my induction burner. I'd love to get a full induction stove but it just wasn't in the cards this time around, and electric stoves have come a long way so I’m not displeased with my electric stove. The induction burner I have works great, heats fast, functions like a gas stove in pretty much every respect, it just doesn't have an open flame and some of my pans don't work on it. Can recommend, especially if you are sensitive to gas or live in a home not piped for gas, it's a great way to go. Not cheap, but worth the cost.

Astronaut's 'science of opportunity' experiments help prepare for launch to the International Space Station

Science ideas are everywhere. Some of the greatest discoveries have come from tinkering and toying with new concepts and ideas. NASA astronaut Don Pettit is no stranger to inventing and discovering. During his previous missions, Pettit has contributed to advancements for human space exploration aboard the International Space Station resulting in several published scientific papers and breakthroughs.

Pettit, accompanied by cosmonauts Alexey Ovchinin and Ivan Vagner, will launch to the orbiting laboratory in September 2024. In preparation for his fourth spaceflight, read about previous "science of opportunity" experiments Pettit performed during his free time with materials readily available to the crew or included in his personal kit.

Freezing ice in space

Have you ever noticed a white bubble inside the ice in your ice tray at home? This is trapped air that accumulates in one area due to gravity. Pettit took this knowledge, access to a -90° Celsius freezer aboard the space station, and an open weekend to figure out how water freezes in microgravity compared to on Earth. This photo uses polarized light to show thin frozen water and the visible differences from the ice we typically freeze here on Earth, providing more insight into physics concepts in microgravity.

Space cup

Microgravity affects even the most mundane tasks, like sipping your morning tea. Typically, crews drink beverages from a specially sealed bag with a straw. Using an overhead transparency film, Pettit invented the prototype of the Capillary Beverage, or Space Cup. The cup uses surface tension, wetting, and container shape to mimic the role of gravity in drinking on Earth, making drinking beverages in space easier to consume and showing how discoveries aboard station can be used to design new systems.

Planetary formation

Using materials that break into very small particles, such as table salt, sugar, and coffee, Pettit experimented to understand planetary formation. A crucial early step in planet formation is the aggregation or clumping of tiny particles, but scientists do not fully understand this process. Pettit placed different particulate mixtures in plastic bags, filled them with air, thoroughly shook the bags, and observed that the particles clumped within seconds due to what appears to be an electrostatic process. Studying the behavior of tiny particles in microgravity may provide valuable insight into how material composition, density, and turbulence play a role in planetary formation.

Orbital motion

Knitting needles made of different materials arrived aboard station as personal crew items. Pettit electrically charged the needles by rubbing each one with paper. Then, he released charged water from a Teflon syringe and observed the water droplets orbit the knitting needle, demonstrating electrostatic orbits in microgravity. The study was later repeated in a simulation that included atmospheric drag, and the 3D motion accurately matched the orbits seen in the space station demonstration. These observations could be analogous to the behavior of charged particles in Earth's magnetic field and prove useful in designing future spacecraft systems.

Astrophotography

An innovative photographer, Pettit has used time exposure, multiple cameras, infrared, and other techniques to contribute breathtaking images of Earth and star trails from the space station's unique viewpoint. These photos contribute to a database researchers use to understand Earth's changing landscapes, and this imagery can inspire the public's interest in human spaceflight.

Installing a UV Water Purification Light: Step by Step Guide

Welcome back to Base Camp WNC. Today, we embark on an informative journey on how to seamlessly install UV lights in your existing water systems. UV lights are essential for purifying water, ensuring that it is free from harmful microorganisms.

Getting Started with the UV Light System The UV light system we're focusing on today is a 55-watt, 110-volt unit, designed specifically for the United States. It comes equipped with two holes at each end, accommodating water fittings. Versatility is key with this design; it can be mounted horizontally, vertically, or at any desired angle. The kit includes a slender glass tube, reminiscent of an elongated test tube. When assembling, slide this tube into the provided ring until it slightly protrudes from the other end. Ensure the ring's pyramid-shaped fixture is correctly aligned to secure the tube. This is a delicate procedure, and I have some tips to prevent the glass tube from breaking.

Assembly Tips

Slide the glass tube gently to ensure it doesn't snap.

The flange present will accommodate a seal, which when pressed, ensures a tight fit. Just let the glass tube protrude slightly and secure it hand-tight.

When sealing both ends of the tube, do not use pliers or exert excessive force. Gentle hand-tightening is sufficient.

Water flows between the glass tube and the metal frame, getting purified as it passes by the UV light, before exiting from the other end.

The kit I’m showcasing comes with one glass tube and three UV light bulbs. An important note on the longevity of these bulbs: while they may still emit heat and light after a year, their purification capability diminishes. Hence, an annual replacement is recommended. Handle these bulbs with care and avoid touching them with bare hands.

Installation Essentials For the perfect fitting, I've innovated with a shower fitting, designed to accommodate the PEX pipe. Applying two wraps of Teflon tape in the direction of the screw ensures a smooth slide. This is especially crucial with PVC components that may have residual bits from the molding process. Add a layer of pipe dope for a tight seal. The location of installation plays a vital role. In my setup, the spring below the house feeds a tank, which then directs the water towards the house. The UV light system sits in between. To ensure a sturdy installation, mount a board (like a 1 by 4) on the wall as a base. Once set, the PEX pipe is clamped onto this board with two plastic clips. This setup allows easy access for future maintenance or bulb replacement. The UV light system's transformer has an indicator – a green light – to show it's functioning.

Wrapping Up Installation can be swift with a bit of experience – it takes me about 15-20 minutes, having installed numerous before. But even if you're new to this, with the right guidance, it's a straightforward process. Thank you for joining us. If you found this guide useful, please like, share, and subscribe. For any further queries or if you need specialized assistance, feel free to shoot me an email or drop a comment on YouTube.  I offer free advice and guidance online, but consultations or installations at specific locations would be a paid service.

Until next time, stay informed and stay safe!

In a fume hood break open an ampule of the liquid and transfer the whole contents to several previously labeled 1 ml REACTI-VIAL vials from PIERCE (catalog 13221Z; $69 for 12 vials; the cap liner must have a Teflon face to contain these materials). The transfer is safest with a positive displacement pipet (Gilson Microman M250). DO NOT use an air displacement pipet (Pasteur or Gilson Pipetman). Close each vial with the special cap provided. Wrap the cap with a strip of Parafilm. Each vial is stored inside a 50 ml polypropylene centrifuge tube with a plug seal screw cap. Cover the cap with Parafilm. Store each individual centrifuge tube inside a larger container (glass jar or metal) sealed with parafilm and label it EXTREMELY TOXIC. These compounds should be stored in a freezer to minimize their vapor pressures. No food should be stored in this freezer.

Reach out to each other 💛 Two kitties float inside of fresh, transparent egg yolks while their eggs fry (as if cracked in the pan). One kitty sleeps soundly, while the other is beginning to stir and puncture its yolk sack in order to reach toward its sibling.

Acrylic paint and craft glitter sealed in epoxy resin on a recycled 12" Teflon frying pan. Felted bottom to prevent wall scratches.

To be honest, I am extremely proud of this piece. In a very direct way, it represents what i hope to accomplish with my art - breathing new life to "trash", keeping plastics out of the water supply (in this case, Teflon), and transforming something ordinary into a unique experience.
