Have you ever looked at a telephone pole and noticed those glass or porcelain pieces on top? They might look like just decorations, but they actually have an important job in communication. These helpful items are called insulators, and they help keep our electrical wires safe and our phone calls clear.
Safeguarding the Flow of Electricity
Insulators have a key job: they stop electrical wires from touching the pole or the ground. Imagine trying to make a long-distance call, and your voice suddenly cuts out after a little while. That wouldn’t be fun, right? Insulators make sure all the electricity stays in the wires so our important phone calls can keep going without any problems.
The Variety of Insulators
These simple objects come in many different styles and colors. While a lot of the older insulators were made from glass or porcelain, some were made from wood and glass, and even animal parts! You’d be surprised at some of the unusual materials used. The size of the insulator is important too. Smaller ones are used for telephone and telegraph wires, while larger ones are made for high-voltage electrical wires. It’s like having a special section for insulators based on how much voltage they can handle!
Keeping Voltage in Check
When it comes to power lines, the voltage affects how big the insulator needs to be. Electricity can be a bit tricky and might try to jump across a distance. That’s where the design of insulators helps out. Insulators with wide “umbrella” shapes and large lower parts act like careful bouncers at a nightclub, keeping the wires away from the pole and stopping any accidents from happening.
A Surprising Hobby
Believe it or not, collecting insulators is a popular hobby! This started becoming popular in the 1960s when utility companies began burying their wires, leaving a lot of old insulators behind. As the saying goes, one person’s trash is another person’s treasure. People who collect insulators come from all different backgrounds. Some like these glass pieces for how they look and use them to decorate windowsills and gardens, adding a bit of shine to their space. Others look for specific types of insulators. Prices can vary a lot; you might find one for less than a dollar or even get one for free at flea markets!
A Historical Touch
Most insulators that collectors have are between 70 and 145 years old, and some types haven’t been made since the early 1900s. Anything that’s old and no longer being produced often becomes collectible, and insulators are no different. They hold a piece of history and connect us to a time when communication was just starting to grow.
Appreciating the Role of Insulators
The next time you see one of those interesting glass or porcelain insulators on a telephone pole, take a moment to appreciate how important they’ve been in the history of communication. They might seem like old items, but they’ve made a lasting impact on how we connect with each other, whether through a phone call or a quick text message. Who knows? You might even feel inspired to start your own collection and join the many people who find beauty and history in these simple artifacts!
Uber driver saves up for 8 years to build a genius expandable container home
Imagine dreaming of an expandable container home that can travel with you, unfolding into a comfortable living space quickly, and equipped with all the essentials.
That’s exactly what Kamal Kadhar dreamed of ten years ago, inspired by innovative designs he discovered online.
Despite lacking formal construction training, Kamal started a journey fueled by determination and passion.
Using his earnings from eight years of driving for Uber, Kamal built a compact yet expandable container home measuring 7.5 feet by 24 feet.
The beauty of his creation lies in its portability – it can be towed by a 4×4 vehicle, eliminating the need for cranes or forklifts.
Kamal’s journey began in a field outside Tiruchirappalli, a southern Indian city, where he constructed his first prototype.
What sets Kamal’s creation apart is its simplicity and resilience. He opted for mechanical winches instead of complex hydraulics to ensure ease of deployment in remote locations.
As Kamal describes it, the expandable container home is like an octopus – small when needed, expandable when necessary, and can withstand disasters like fires, hurricanes, or floods.
The relocation process is as easy as moving a shipping container, making it legally transportable anywhere in the world using a 4×4 SUV.
The journey wasn’t without its challenges.
After investing almost a decade of hard work and facing financial strain, Kamal’s family was on the verge of giving up.
However, witnessing the prototype changed everything. Realizing the idea’s value brought relief despite the personal and financial sacrifices.
Kamal’s unconventional path involved learning everything from YouTube, combining his experiences as an Uber driver with visits to construction sites and apprenticeships at a builder’s shop.

His creative mindset was founded on his father’s small scrap metal shop, where he played with metal and aluminum, shaping the project to resemble a regular shipping container.
The main structure starts small at 7ft 6in and expands to 20ft.
The expandable container home takes less than 2 hours to build, with a foundation not required.
It can be adjusted on uneven surfaces using built-in leg jacks.
The roof opens with stainless steel hinges, both mechanical and electrical components, avoiding hydraulics for reliability.
The roof opens to add solar panels, maximizing power generation for personal use or resale to the government by connecting to the grid.
The sides expand mechanically, controlled by a hinge, making it easy to pull and open with just one finger.
The kitchen, also expandable, is attached to the bathroom facility. Utilities run down the middle, and it’s designed to hook up to city sewage.
The living area is spacious, with a total interior size of 300 square feet, and the bedroom features a foldable bed.
This house has been tested in a remote village, and even non-professionals helped build it confidently.
You can expand it and adjust the interior to make it more spacious.
