1. The Juicero (2016)

The Juicero

Inventor: Doug Evans

Why It’s Bad: Imagine paying $400 for a juicer that requires Wi-Fi to function, only to find out you could achieve the same result by squeezing the juice packs with your bare hands. It’s the ultimate symbol of Silicon Valley’s knack for solving problems that don’t exist. Spoiler alert: it didn’t last long, but the memes will live forever.

2. Google Glass (2013)

Google Glass

Inventor: Google X (now X Development LLC)

Why It’s Bad: Ah, Google Glass—the gadget that made you look like a cyborg and alienated you from polite society. This wearable tech was supposed to make us all feel futuristic but ended up being an expensive way to invade privacy and get weird looks. If you wanted to be labeled a “Glasshole,” this was your golden ticket.

3. Hoverboards (2015)

Hoverboards

Inventor: Shane Chen (original design)

Why It’s Bad: Hoverboards were the must-have gadget that promised to make us all look cool while zipping around town. Instead, they made headlines for spontaneously combusting and sending users flying. Banned from airlines and sidewalks alike, these rolling fire hazards turned a hot trend into a literal hot mess.

4. Samsung Galaxy Note 7 (2016)

Samsung Galaxy Note 7

Inventor: Samsung

Why It’s Bad: Samsung’s Galaxy Note 7 was the explosive device you didn’t want in your pocket. With batteries prone to catching fire, it was more likely to land you on a no-fly list than help you multitask. The recalls and bans turned this “must-have” gadget into an infamous pyrotechnic display.

5. Amazon Fire Phone (2014)

Amazon Fire Phone

Inventor: Amazon

Why It’s Bad: Amazon’s Fire Phone had all the gimmicks and none of the substance. It boasted 3D visuals and a dedicated button for Amazon shopping, but lacked essential apps and usability. It’s a classic case of trying too hard to be different and ending up on the clearance rack.

6. Theranos (2003-2018)

Theranos

Inventor: Elizabeth Holmes

Why It’s Bad: Theranos promised to revolutionize healthcare with just a drop of blood. Instead, it delivered one of the biggest frauds in Silicon Valley history. Faulty tech and deceit put patients at risk and turned its founder into a cautionary tale about the dangers of unchecked ambition.

7. Oombrella (2016)

Oombrella

Inventor: Wezzoo

Why It’s Bad: The Oombrella was marketed as a “smart” umbrella that could notify you of weather conditions. Apparently, checking your phone was too much effort. It was an overpriced, over-engineered gadget that solved a non-existent problem. Thanks, but I’ll stick to my regular old dumb umbrella.

8. Quibi (2020)

Quibi (1)

Inventor: Jeffrey Katzenberg and Meg Whitman

Why It’s Bad: Quibi aimed to change the way we consumed media with short, mobile-focused videos. Despite a high-profile launch, the lack of compelling content and the audacity to charge for something we get for free on YouTube led to its rapid demise. It was a billion-dollar idea that flopped faster than its 10-minute episodes.

9. Kohler Numi Toilet (2018)

Kohler Numi Toilet

Inventor: Kohler

Why It’s Bad: The Numi is a toilet that costs over $6,000 and comes with features like a heated seat, foot warmer, and built-in speakers. While it might be the throne of your dreams, most people found it ridiculously overpriced for a place to do their business. It’s a royal flush of money down the drain.

10. Jibo Robot (2017)

Jibo Robot

Inventor: Cynthia Breazeal

Why It’s Bad: Jibo was designed to be your friendly home robot. Despite its charming personality, it couldn’t do much beyond turning its head and making small talk. For its hefty price tag, you’d expect a lot more functionality. Instead, it quickly became a fancy paperweight with a cute face.

That’s a Wrap

And there you have it—the crème de la crème of American ingenuity gone awry. These inventions remind us that not every idea is a winner, and sometimes, even the best intentions can lead to the most spectacular failures. Here’s to hoping the next decade of innovation brings us fewer flops and more triumphs. Remember, folks, if at first you don’t succeed, maybe check if your invention really needs Wi-Fi. Until then, we’ll be here, ready to laugh at the next big flop. 

Ask someone what they know about farming, and you may get outdated answers. Many people will talk of the infamous red barn, maybe some cows roaming the fields, or a straw hat. But, in reality, farming is far from outdated. In fact, farming is often one of the first industries to adopt new designs, technologies, and practices. And there’s no clearer way to see it than when you consider the design and evolution of farm and field equipment.

The earliest known farm implements date back as far as 5500 BC. In fact, the first plow is considered to be the “forked” sticks dragged through dirt in the region of southern Mesopotamia (now south-central Iraq). These sticks created the trenches in which seeds would be planted. As history shows, with increased technology and resources comes change and farming equipment changed greatly from these first “plows.”

18th Century

This century was really the time in which farming machinery became more mechanized. Wood was still a major material for farming equipment, but cast-iron metal was making gains as well. Although the first patent for the cast iron plow wasn’t issued until 1797 to Charles Newbold, it was during the 18th century when the use of cast iron as a material really took off. This century also saw the invention of replacement parts, saving farmers time and money by allowing them to repair and replace their machinery more easily, rather than having to buy new.

19th Century

Farm equipment and farm equipment technology really made great leaps starting in the 19th century. It was during this century that agricultural equipment turned away from horses and oxen as power sources and toward steam power. Then, at the end of the 19th century, steam power was replaced with combustion engines (using kerosene or gasoline) which weighed less, required less human interaction, and were also more efficient in general. That was just the beginning.

20th Century

During these years (1901-2000), we saw additional changes in farming equipment that really set the tone for what was to happen next. Diesel powered tractors were invented, giving way for more fuel efficiency and longer engine life. Hydraulics were introduced, giving farmers more versality in the ways in which the equipment could operate, move, and control implements. And Power Take Off (PTO) was also introduced which gave farm vehicles the ability to directly power their implements from the engine. Toward the end of the 20th century even more changes came when mechanical components were being replaced with electrical systems and devices. This laid the foundation for what would come next.

21st Century

This century has seen huge gains in the technology used in tractors. GPS was introduced, sensors were added everywhere, vision systems became available, and smart farming was born along with autonomous tractors. GPS is the backbone of autonomous tractors because it uses real-time location data to guide the tractor within defined parameters. Sensors detect changes on the ground, like soil conditions, and in the environment, like weather or plant health. They also provide critical information regarding the overall operational health of the tractor, allowing farmers to address maintenance issues before they’re too big to handle in the field. Lastly, although autonomous tractors guide themselves, we still need the farmer to monitor the operations, and 360-degree vision cameras are just the tool to do so.

22nd Century

Where and what farming equipment will be in the future is hard to predict but can be done with a little creativity and consideration for history. Farming equipment has really followed the trends from Industry 1.0 to 4.0 and with the prediction for Industry 5.0 to focus on societal values and wellbeing over economic values and welfare, we’ll likely see some changes in this realm. Meaning we’ll likely continue to see machinery and humans collaborating for the wellbeing of all while also squaring in on eco-friendly practices and reducing environmental impacts.

Of course, these are summaries of changes in the agricultural industry as a whole. That includes all types of operable equipment as well as the implements and other tech used in farming. But one piece of equipment stands out no matter what type of farming is being done. That’s the tractor. It’s synonymous with farming and agriculture. So, for some fun, below is a timeline of some of the biggest moments in the birth and life of what we call the tractor.

1892: A 43-year Iowa man named John Froelich is accredited with inventing the first successful gasoline-powered engine. The engine could be “driven” backwards and forwards so although it wasn’t called a tractor at the time, it essentially was the first tractor ever invented. John and others attempted to manufacture and sell this tractor (out of Waterloo, Iowa) without much traction so production turned to stationary engines only and John moved on.

1901: Two mechanical engineering students at the University of Wisconsin (Charles Hart and Charles Parr), founded the Hart-Parr Gasoline Engine Company in Madison, Wisconsin. They produced traction engines which coined the term “tractor”, and the first commercially successful tractor rolled off their assembly lines in 1901, kicking off the 20th century and so much more in tractor technology.

1902: This was a big year for farm tractors and agricultural machines as a whole. It was this year that five agricultural equipment manufacturers merged to form International Harvester. And, in 1905, International Harvester manufacturers its first tractor.

1904: Benjamin Holt develops the first crawler tractor, out of California. The change with this tractor is that rather than wheels, it was equipped with tracks. They named this tractor the “Caterpillar” which would also be the name by which his company was named!

1920: Massey Harris purchases Wallis Tractors to create the first four-wheel drive tractor. Fun fact – Wallis Tractors was founded by Henry Wallis who was actually the son-in-law of Jerome Case, the founder of the Case Corporation, a major player in ag equipment manufacturing.

1923: John Deere produces their legendary Model “D” Tractor, one they produced for nearly 30 years. During this same year, the International Harvester Farmall tractor was produced, another legendary tractor because its rear wheels were set further apart while the front wheels were narrow.

1928: SAME, an Italian tractor manufacturer secures credit for producing the first diesel powered tractor. Two short years later in 1930, it can be said that 15% of farmers are using tractors on their farm operations.

1931: Caterpillar manufactures their first diesel-powered track-type tractor.

1932: Allis-Chalmers (a company first formed in 1901), collaborates with Firestone to introduce pneumatic rubber tires to tractors, changing the tractor game as it relates to traction and fuel economy. Within five short years, these tires replaced the majority of steel wheels used up until this time.

1935: International Harvester combines diesel engines and wheeled tractors into one.

1941: Minneapolis-Moline introduces the world’s first factory-produced LPG (liquified petroleum gas) tractor, claiming 10% more power but fewer operating costs.

1954: Tractors officially outnumber horses and mules on farms.

1958: Minnesota farmers John Steiger and sons designed and built a tractor in their own barn and painted it lime green. Soon after they were officially in business by 1963 and had developed the very first tractor with a rear PTO option on articulated four-wheel drive tractors. They even pioneered electronic control systems for tractors, as well. After 32 years in business, Tenneco (parent company of Case International Harvester) purchased the Steiger brand.

1959: Allis-Chalmers creates technology for electric fuel cells. Although it didn’t take off in tractors, it can be considered technology that gave NASA the ability to “put a man on the moon”.

1960: Case creates the first tractor cab. Later, in 1963, Steiger introduces the first 4WD tractor with an enclosed cab. Enclosed cabs became a very popular addition to tractors in the next few years.

1961: Allis-Chalmers introduces their D-19 tractor, the first mass-produced tractor with a turbocharged diesel engine.

1966: Versatile is the first to mass-produce 4WD tractors and are able to price them out at a rate similar to the cost of smaller 2WD tractors that are currently being sold.

1969: Kubota Corp. introduces it’s very first tractor in the United States with instant success. Kubota Tractor Corp. is formed in 1972 to expand its presence in the market.

1973: Allis-Chalmers designs and manufacturers load-sensitive hydraulics for two of its tractor designs.

1985: Case and International Harvester merge to form Case IH.

1986: Massey Ferguson introduces the very first electronic lift control 3-point hitch, and it comes standard on all of their tractors. This technology gives farmers much more control over height, rate of drop, and depth (as well as speed) for implements and attachments.

1987: Caterpillar manufacturers tractors with rubber tracks, greatly reducing soil compaction.

1988: The first tractor engineered by newly combined Case IH is released with 100,000 produced in the first 15 years. What tractor was it? The Magnum tractor.

1990: AGCO is formed after a buyout of Deutz-Allis from KHD, starting the first of many acquisitions, leading AGCO to become the third largest producer of ag equipment worldwide.

1991: This was the year that the world’s first tractor with a full suspension system, and the ability to operate at 35 mph road speeds, came to be with JCB’s Fastrac tractor in Great Britain.

1992: RTK (real-time kinematic) technology debuts this year, one of the most important pieces of technology aiding in agricultural equipment guidance and movement.

1994: GPS and satellite technology is introduced. Case International rebrands to Case IH.

2004: Fendt introduces the Tractor Management System, software that monitors and controls engine speed relative to ground speed.

2010: Case IH manufactures and ships the Magnum series tractor which is the first unit from all manufacturers to meet EPA Tier 4A emissions standard for ag equipment.

2013: CNH Global N.V. and Fiat Industrial S.p.A. merge, making CNH Industrial N.V.

2020: Monarch Tractor showcases the world’s first fully electric smart tractor which is operated on a single electronic platform and with or without a driver. At the same time, Soletrac comes onto the market with a battery-powered tractor specific for orchards and vineyards.

2022: John Deere lets the world know that they have a fully autonomous tractor ready for production.

2023: New Holland is the first of the major ag OEMs to introduce an all-electric-powered tractor.

As we look back over the centuries, it’s clear that the fields of agriculture have always been a fertile ground for innovation. From the rudimentary stick plows of ancient Mesopotamia to the high-tech autonomous tractors of today, farming equipment has undergone a remarkable transformation. Each advancement reflects not only technological progress but also a deeper understanding of efficiency, sustainability, and the needs of both the land and those who work it.

As we venture into the future, with a vision sharpened by Industry 5.0 and its focus on societal values, the next chapters of agricultural innovation will likely be even more transformative. The ongoing evolution from mechanical beasts of burden to intelligent companions in the field highlights a pivotal shift in our relationship with technology and nature. These tools, once simple extensions of human effort, are now partners in a dance of productivity and stewardship.

In embracing these changes, we not only continue the legacy of innovation that defines human progress but also ensure that the future of farming—and by extension, our world—is as fruitful as the fields our forebears once tended. Let’s continue to watch, learn, and grow as the next generation of tractors and beyond redefine what it means to work the land.

Whether we like it or not, Artificial Intelligence is starting to change the landscape of modern life. If you’ve read a few emails or blogs from your favorite companies, there’s a good chance some of that content was written using AI. In fact, in a recent survey, 57% of enterprise marketers reported using AI in email campaigns. A whopping 99% of those respondents reported that the results were either extremely or somewhat positive.

Why are you seeing this from a manufacturing services provider? Because every company out there needs to communicate with their target audience. Whether you’re a manufacturer who’s bidding to build components for a commercial airline, or a dog groomer looking for furry clients, you should always be looking for new ways to communicate.

There are AI tools for creating video and images, too, but this blog is intended to be a basic guide on how to get started and use ChatGPT for written communication.

Limitations With AI

Before you get started, it’s important to understand that there are limitations to these tools.

For instance, in ChatGPT, the data and knowledge are only as current as 2021. Any output should be thoroughly reviewed for technical accuracy before being used.

You will still need to create a prompt and tell the AI what type of content you are looking for. This part of human creativity may never be replaced.

Advantages to Using AI

AI can help you refresh or transform old content. For example, you could prompt AI to update your summer themed email campaign to instead have a winter or holiday theme.

If you need to target multiple audiences, AI can quickly help you rewrite content that is more appropriate and appealing to each audience.

If you experience “writer’s block,” ChatGPT could be used to generate new ideas or help write a tricky part of your content.

Getting Started

All you need to do is create a username and password on the ChatGPT website: chat.openai.com

The Prompt

This is the fun part! You can enter as much, or as little, information in your prompt as you want. If you add more details, context and specifics, the output will be closer to what you’re looking for. With each AI response, you can enter a new prompt to either continue a conversation or modify what was already generated.

I recommend you experiment with all sorts of prompts to get an idea of what you get out of it.

  • Ask a question: “How do I write the best email?”
  • Copy/paste content you already made and ask AI to change it: “Re-write this email with a Christmas theme” – or – “Re-write this blog in the voice of Stephen King.”
  • Request new content: “Write a safety-first post about pool parties on the 4th of July.”
  • Rewrite a prior response: “Rewrite that, but change X to Y and add Z.”

Below is a prompt that I entered in ChatGPT followed by the output that was generated. Before (or after) you read what ChatGPT generated, check out the original Top 7 Travel Essentials blog written without AI. Who did it better?

Example Prompt:

Write a blog about the “Top 7 Travel Essentials” for a FlexTrades technician. There should be a short introduction, a brief explanation of each of the 7 items and a short conclusion. Write in the voice of Eddie Murphy.

  1. Sleep essentials and comfy clothes
  2. Cooking Supplies
  3. Video Games
  4. Entertainment, Streaming, Movies, Music
  5. Laptop or Personal Computer
  6. Tools
  7. Pets

Tis the season for snow! With that, we thought we’d make our monthly installment of the How It’s Made article about snow. There are two types: natural and man-made. We’ll outline both below.

Natural Snow

The Earth’s atmosphere is filled with water and water droplets. At times, these droplets will combine with dust, bacteria and other items floating in the air. When temperatures in the atmosphere drop to very cold levels, the water/dust/bacteria-combined droplets freeze and become tiny ice crystals. A snowflake is created when 2-200 of these ice crystals bond together. With the help of gravity snowflakes fall from the clouds to the ground, a distance of nearly 20,000 feet and a journey that lasts approximately an hour!

Man-Made Snow

When I say man-made snow, I’m talking about the snow you see at ski resorts. To ensure their success on a seasonal basis resorts must create their own snow. This snow is denser than natural snow and doesn’t melt as soon as  when packed down on the trails and hills. So, how do they make it?

Key Components

  • Snow Guns or Fan Guns
  • Power Connections and Power Pedestals
  • Air Compressors
  • Water Connections Snowmakers

Snow guns and fan guns are the large pieces of equipment that blow the manufactured snow onto the mountains. You can find these on top of poles and at ground level. Although the two types of guns perform the same task, they operate differently.

  • Fan guns require the use of electricity and power connections. As a result, an electrical distribution system is created through the use of power pedestals (electrical boxes) and power cords.
  • Snow guns do not utilize electricity. Rather, this type of gun operates through the use of compressed air. Air compressors create the power that propels the snow out of the guns.

Regardless of gun type, both types require water. Water connections consist of what is essentially a large fire hose that can withstand a high level of water pressure (PSI) in addition to many miles of water pipeline underground and hydrants at each fan gun hookup.

Finally, snowmakers! Yes – you can create a career (at least seasonally) by being a snowmaker. These workers evaluate weather conditions first and foremost. Then, based upon weather conditions, they manipulate, coordinate and control the operations of the making systems. This happens by creating the “just right” mix of water, temperature, and air. These mixes vary on each hill, as well, helping to create the various difficulty levels of each ski run.

Check out the video below to learn how the experts do it.

Other Key Components

  • Snowmaking ponds (water sources)
  • High-powered turbine pumps (for pushing water throughout the systems)
  • Air coolers (cooling the compressed air)
  • Computers (for monitoring and adjusting the making process)
  • Weather stations (sending weather and humidity to the computer)
  • Groomers (for compacting and grooming to ideal conditions)

With all that said, I can’t say I’m signing up to be a snowmaker anytime soon but I might try to be a snowflake maker. Below are links that will bring you to templates and instructions for making paper snowflakes. Try it if you’re ever stuck inside on a snow day!

It’s the heart of summer now and that means many things – shorts and t-shirts, barbecuing and grilling, backyard pools or trips to the beach and, in non-COVID-19 times, professional baseball games. It also means celebrating Independence Day by setting off large explosives in the sky (a.k.a. fireworks). That got us thinking – how are fireworks made? And that, of course, brought us to this month’s How It’s Made article.

Before we get to the specifics, I want to point out that fireworks can be placed in three general categories:

  1. Sparklers
  2. Fountains
  3. Aerial Shells

About Fireworks

Sparklers are hand-held fireworks, fountains are ground-based fireworks, and aerial shells are the large ones that you see exploding in the sky. You can break these categories down even further but, for the sake of this article, we’ll leave it at these three types. Regardless of the type, each firework contains key elements in various levels or combinations.

Those key elements can be seen in the image below which can be found at Compoundchem.com. Key elements of fireworks include:

  1. Metal Compound Pellets (or Stars) – These produce the colors you see when fireworks are lit.
  2. Fuel/Bursting Charge – This creates the burn/blast of the firework.
  3. Oxidizers – In combination with the fuel, this produces the blast.
  4. Binders – Required to hold the mix of elements within the firework.
  5. Chlorine Donors – These are used to deepen the effects of certain colors.

As I mentioned, different combinations and different levels of these elements are used depending upon the type of firework and intended effect of the firework.

With all that said, let’s get to it.

Below are short summaries of the way in which each of the three types of fireworks are made. As we move through the categories, each type gets a little more complex in nature and the way in which they are built.

Sparklers

How Are Fireworks Made (1)

These slow burning wands of sparkles are made of a metal compound (depending upon color), black powder/gun powder (fuel/bursting charge), and a binder. When these elements are mixed with water, a slurry is created. Once the slurry has been concocted, the wand is dipped in the slurry then dried. This is the end of the wand that, when lit, emits the sparkles. When the fuse is lit, the powder ignites. This, in response, pushes the metal compounds out, creating the sparks.

Fun fact: The end of the wand can reach temperatures upwards of 2900° Fahrenheit!

Fountains

How Are Fireworks Made (2)

Fountain fireworks are a bit more exciting than sparklers and, as a result, have more elements as well. Fountains consist of the following parts:

  1. Base
  2. Tube (made of paper or plastic)
  3. Clay Plug and Choke
  4. Metal Compound and Fuel
  5. Fuse & Protective Paper

For these, imagine a rocket. A mixture of the metal compounds and fuel are placed into a tube (the rocket), which sits on a base. The mixture is, of course, based upon the desired effect. Also, inside the tube is a clay plug at the bottom and a clay choke at the top. A fuse is placed through the clay choke at the top and then wrapped in protective paper. When lit, the flame travels down the fuse into the tube (the bottom of the rocket) to ignite the metal compounds and fuel which creates the display and sparks. Note: due to the nature of this setup, it does not “launch” the firework.

Aerial Shells

How Are Fireworks Made (3)

Bigger doesn’t always mean better but, in the case of fireworks, it usually does. Aerial shells are the largest in size when it comes to firework types. As a result, aerial shells are slightly more complex than the others in build.

It’s important to remember that, unlike other fireworks, there are two bursts that happen in aerial shells:

  1. The lifting charge – to lift the shell into the air
  2. The bursting charge – creating the burst of color and sound

To generalize the makeup of aerial shells, consider that of the fountain firework as aerial shells are similar. Where the differences lie is in the number of fuses, the purpose of the fuses, the number of chambers, and the design patterns.

Aerial shells have two fuses: the time-delay fuse and the fast fuse. It might not sound like it but each fuse takes the same amount of time to ignite. The difference between the two is that the timed fuse ignites the charge/cache of powder that launches the shell. After launch, this fuse continues to burn until it reaches the fast fuse. The length and burn time of the time-delay fuse is calculated very carefully to ensure that the shell is at the appropriate altitude for full ignition. When the fast fuse is lit, it ignites the metal compounds and sets the burst into the sky.

It might seem simple enough but, to add to the effects and complexity, multiple chambers of gun/black powder will be built into the shell. These chambers go off at different times creating the many effects of light, color, or sound. Additionally, the explosive shells/stars can be strategically placed inside the tube in a desired shape (say a flower) to then explode in the sky in that same shape (a flower).

Extra Information

Now, if all that sparked (see what I did there?) more curiosity in you, I’ve linked some great articles below for you to check out:

Keep in mind on this last one: your typical 20-minute show, set to music, can cost upwards of $40,000. Also, they’ll often put this show on twice in one day!

Must Watch Before You Go

A reader of our How It’s Made articles asked if we could share our knowledge about recycling. As a result, we adapted our How It’s Made article this month to an article titled “How It’s Done.”

In recognition of National Recycling Day on November 15, this edition will focus on what happens in a recycling facility. Before (or after) you read on, check out an earlier article we posted to help you understand just What Can Be Recycled.

As you read through the process below, keep in mind that states and cities vary in their abilities to recycle. However, the general process outlined here can be followed for mixed material recycling centers.

How is Recycling Done (1)

Step 1: Collection

Recyclables are collected from curbside or drop-off locations then delivered to the recycling/recovery facility.

Step 2: Facility Arrival

The trucks unload recyclables into a yard or storage area.

Heavy equipment pushes the material onto a conveyor belt or into a hopper which then feeds a conveyor belt.

Step 3: Presort

In this area, workers manually remove materials that are not recyclable or would damage the facility equipment.

Examples include: dirty paper/cardboard, scrap metal, plastic bags, bulky & oversized plastics, e-waste, hoses, toys etc.

Step 4: Screening

Throughout the entire process, large rollers screen out materials.  These rollers are essentially augers with blades. The build, size, and spacing of the blades pushes forward desired recyclable materials and undesired materials downward.

Often, the first material screened is large cardboard. These screens can also filter out materials considered too small for recycling.

How is Recycling Done

Step 5: Sorting

Workers manually sort non-recyclable products from mixed materials. Workers will also pull out any materials that are difficult for equipment operations.

As a result, we have sorted various products into specific materials. These products are now moving on a series of conveyors to specific places within the facility. Those products include:

  1. Newsprint
  2. Mixed Paper
  3. Cardboard
  4. Plastic

So, what else is left? Glass and metals.

How is Recycling Done (2)

Step 7: Metal Magnification

Giant magnets pull tin cans, iron containers, or steel containers from the conveyor belt. After this, another conveyor belt takes these containers to a specific area of the plant. Plastic, aluminum, and glass containers continue down the line.

Step 8: Screening

In this step, screens break the glass and separate it from plastic. A conveyor takes the broken glass to the glass processing department. This department breaks the glass down even further for additional processing or shipment out.

Step 9: Eddy Current Separator

This sorts aluminum from the mixed product through the use of an electric current. In addition, a conveyor takes the aluminum product to another area of the plant for processing.

Step 10: Sorting

More manual sorting by operators within the facility occurs here to gather any other products which are not recyclable.

At this point, plastic containers and small pieces of paper or film are all we have left.

Step 11: Optical Sorting

In this area, machines determine different types of unsorted materials. The machines identify different materials based on how light reflects from the material’s surface. This step determines the material type, color, and shape. Air pulls recognized material downward (or upward) onto another conveyor belt.

This step uses optical sorting machinery. One sorter will target paper. Another sorter will target plastic film. Upon completion of optical sorting, we should be left with just plastic containers. Therefore, each type of product or material has been sent to its own storage area. For instance, plastic bottles and containers are in one area. Similarly, cardboard is in another area.

So, what happens next?

Step 12: Baling

Baling machines operate with very high levels of pressure to compact materials into bales. Yes, like hay bales but made of different materials and square in shape. Wire wrapped around ensures the bales stay together.

Fun fact: These bales can weigh as much as 1 ton!

Baled product is ready for pickup and delivery to recyclers specialized in the materials. For an understanding of those processes, check out the links below:

As wild as it seems, we can trace back the invention of jet engines to 150 BC with the development of the aeolipile. And it is truly the aeolipile’s technology that allowed Dr. Hans von Ohain and Sir Frank Whittle to invent the jet engine as we know it today, albeit it separately and unbeknownst to each other. Additionally, it was Sir Frank Whittle’s jet engine that provided the United States of America the initial technology to build their own jet engines.

Sir Frank Whittle was an English aviation engineer as well as a test pilot in the Royal Air Force. It was in 1930 that he received his first patent on turbojet propulsion and, in just ten short years, he was able to construct, prove out, and secure his first contract of purchase for what was then called the W1 Whittle engine. It was May 1941 when the first historic flight with this new technology occurred.

This leads us to the fall of 1941 when a group of GE engineers in Lynn, Massachusetts received a secret present from King George VI via wooden crates on aircraft, as part of a contract from the U.S. War Department. Inside of the crates were parts of the first jet engine ever flown by the allies; a Whittle engine. The goal of this gift? To improve the handmade engine, bring it to mass production and help win the war.

Over 1000 people worked on the clandestine project, but only a select few knew the goal and what was being built. Those that did know were told they couldn’t talk to anyone about the work being performed. If they did, the consequence was death. As a result, they were called the “Hush-Hush Boys.

With a timeline of 6 months, the team of engineers and technicians were tasked with redesigning the jet engine for commercialization. The accomplishment was completed in five months and in the fall of 1942, the first official aircraft flight occurred, powered by two jet engines, producing a total of 2,600 pounds of thrust.

The Jet Story:

 

How It’s Made – Plastic

Plastic has been around for much longer than most of us know. In its earliest form (some say as early as 1600 B.C.), plastic was produced by Mesoamericans who harvested latex from the Panama Rubber Tree and processed it with liquid from the Morning Glory Vine. However, the production of plastic (as we now know it) started many years later when Polyvinyl Chloride (PVC) was invented during the 1930s. Since then, there have been other types of plastic discovered and invented with each having its own strengths and weaknesses, which ultimately determine the end use.

So, how is it made?

Step 1: Raw Material Extractions

Crude oil and natural gas are extracted (drilled) from the ground then transported to a refinery.

Step 2: Refining

During the refining process, these natural materials are turned into multiple products including ethane and propane (which are the foundation of plastics). The refining process is very similar to how gasoline is made. With the assistance of a high-temperature furnaces, as well as pressure, ethane and propane are broken down into smaller molecules creating ethylene and propylene.

Step 3: Polymerization

In this stage, catalysts (a.k.a. chemicals) are added into the process and bond individual molecules into a polymer. When heated, polymers are incredibly moldable, making them great for plastic products. There are two ways in which this polymerization process can occur, and each way makes its own polymer (or resin), and each resin has its own set of pros and cons (which ultimately determines the end product it’s used in). You can find resin types in the Resin Identification Codes (RICs) on plastic products. Resins include Polyethylene Terephthalate (PET), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC) and Polystyrene (PS) among others. PET is the most commonly used plastic in the world.

Step 4: Nurdle Making

You read that right… now it’s on to nurdle making! Nurdles are little plastic pellets made from the resins created in the polymerization process. The process to do so is through melting and cooling operations. Once these lentil-sized pellets are produced, they are shipped from a petrochemical refining facility to manufacturing facilities where they are melted down and formed into a final product.

Step 5: Plastic Forming & Fabrication

Manufacturers compound, mix, and melt the plastic pellets with other ingredients to very specific recipes. When followed, these recipes determine the characteristics and properties of the plastic product. The melted plastic is then formed into shape by plastic forming machinery, which is determined by the application of the product.

Common Machinery Used to Form Rigid Plastic Products Includes:

  • Injection Molding
  • Extrusion Molding
  • Blow Molding
  • Compression Molding
  • Thermoforming
  • Rotational (Roto) Molding
  • Polymer Casting

Candy Corn, that’s right, let’s talk about it. 

The sweet treat that divides the nation remains a mystery to the masses. Today, we’re going to tackle a few questions and figure out what candy corn is, how it’s created, and most importantly – where it goes after Halloween. 

Candy Corn Ingredients 

Candy corn has four main ingredients: 

  1. A “slurry” (as they call it) is similar to a buttercream. This is created with vanilla and sugars. 
  2. Food coloring is used to individually color each layer with yellow and red dyes. 
  3. The surprise ingredient – (and my personal favorite) marshmallow! Marshmallows are broken down into the slurry to create the light and fluffy texture of the candy corn itself. 
  4. Lastly, the confectioner’s glaze. This is made of honey, gelatin, sesame oil, sugar and salt. 

The Process 

The slurry is taken from a large industrial mixer and placed into three different containers; each container holds a designated layer of the candy corn: yellow, orange, and white.  This container continues to mix the solution so that the slurry maintains the same consistency.  

Wooden trays are dusted with dry cornstarch and then loaded onto the belt where each layer then fills the candy corn imprints. Due to the liquid nature of the material, there is no wait time in-between. Each layer is immediately placed on top of the other to dry. 

Each wooden tray holds 1300 corn pieces, and the machinery can produce 25 boards per minute! 

Once this process is complete and the candy corn is fully formed, they’re tossed into a rotating bin. In this rotating bin, technicians then toss the confectioner’s glaze onto the candy corn pieces until they’re evenly coated. The drying and coating process can take 4-5 days to complete.

Alright, so where does it go? 

Whether you love candy corn and are eager to find it year-round, or you can’t wait for candy corn to leave the shelves, you must wonder where the leftovers go. 

 

Last year, 35 million pounds of candy corn was produced across the United States. Only 70% of all candy corn is effectively sold before Halloween. Where does it all go then? 

 

We did some digging. 

Despite popular belief, “the trash” isn’t the main answer. 

In fact, the answer may surprise you. 

 

Once Halloween concludes, candy corn sales resume. The day after Halloween, candy corn is wiped from the shelves for highly discounted prices, and resellers will snatch up the leftovers. 

 

Candy corn stays fresh, if unopened, for around nine months! In fact, you can find candy corn year-round with online retailers like Amazon.  

 

Well, there you have it! This sweet treat has many layers – from its creation in the 1880s to mimic corn kernels for industrial times, to secret ingredients like marshmallows folded in to guarantee its shape. While candy corn is consumed by many year-round, Halloween is simply the best time to grab them in-store! 

On September 11th, 2001, the unthinkable happened when four airplanes were hijacked by militants associated with the extremist group al Qaeda. Of the four planes, two were flown into the twin towers of the World Trade Center in New York City.  Almost 3,000 people were killed during these terrorist attacks resulting in not only major US initiatives to fight terrorism but also paths of grief for all Americans. To recognize that grief and commemorate the victims of these 9/11 attacks, the U.S. Navy commissioned the USS New York (LPD-21), one of six Navy ships with New York in the name. This ship was different though. This ship, the USS New York (LPD-21) is a massive ship with 7.5 tons of steel recovered from the World Trade Center and Ground Zero. The steel is forged into its bow of the ship which is significant. It symbolizes the strength and resiliency of citizens as the ship sails forward, around the world. In fact, the motto of the USS New York (LPD-21) is “Strength forged through sacrifice. Never forget.”  

Although named after New York, the USS New York (LPD-21) was not constructed there. This mighty ship was constructed at the Northrop Grumman Ship Systems/Avondale Shipyard in Avondale, Louisiana.

Avondale Shipyard sold, now called Avondale Marine | WorkBoat 

The steel from Ground Zero was melted down at Amite Foundry and Machine in Amite, Louisiana. Not only was Amite Foundry and Machine close to the shipyard, they also had the capacity to do a job of this size. You could say the foundry specializes in jobs of this size. They’ve been known to turn down molding jobs for product weighing less than 1,000 pounds and are also known to make mold products that weigh as much 119,000 pounds. Depending upon the economy, Amite Foundry and Machine has a goal of producing 24 million pounds of metal per year. How did they make the bow stem? By melting a total of 24 tons of steel (7.5 tons of that being from Ground Zero) and molding it into the bow stem. With the bow being front and center of the ship, the steel from Ground Zero will lead the way everywhere it goes.  

With the bow completed, the rest of the ship was constructed. To construct a ship, the process starts with steel plates longer and wider than an average bus. These plates are cut into panels, bent on hydraulic presses to match the shape of the ship (or rolled to form the needed contour). Once formed, these panels are painted then welded together to form sub-assemblies of the ship. Once complete, the sub-assemblies are moved by large cranes and transport vehicles across the shipyard to the final build location of the ship. While all of this is occurring, the ship is also built out with internal mechanisms, equipment, cabling, etc. You can find a great video of this process (and really understand the sheer size of the process) here. Once the ship is close to being completed, it will be launched into the ocean where the final touches are added internally and it’s prepped to start sail.  

Final touches include:  

  • A New York City subway sign from the station beneath the World Trade Center  
  • A display case of hats and uniforms from first responders (including a firefighter’s helmet) 
  • A mural of the twin towers with the words Never Forget 
  • A banner with the many  names of the victims of 9/11 

A general timeline of the USS New York (LPD-21) is as follows:  

  1. August 2002: New York’s Governor (George e. Pataki) receive approval for his request that a United States surface warship bestow the name of New York to honor the victims of 9/11. 
  2. August 2003: Northrop Grumman Ship Systems is awarded the contract to build the USS New York (LPD-21). 
  3. September 2003: Amite Foundry and Machine melted steel down to form the bow stem of the ship.   
  4. March 2008: the USS New York (LPD-21) was christened in a ceremony at shipyard. 
  5. August 2009: the ship was delivered to the Navy. 
  6. October 2009: the ship set sail for Norfolk, Virginia.  
  7. November 2009: the ship passed the World Trade Center site for the first time. 
  8. November 2009: a commissioning ceremony took place in New York City.
     

From the very beginning to the very end, it took 7 years to build out this magnificent ship. There were many hands involved in the process including those who poured the metal at an unheard-of foundry in Louisiana to every welder who brought the plates together down to the last crew member to board the ship. This 9/11, let’s remember those who made this memorial ship possible in addition to the first.
