Transformer trucks that turn into large banquet halls at the press of a button have become popular in many rural areas around China in recent years.

Recently, a video showing what looks like a container truck capable of morphing into a banquet hall in just six minutes went viral on Chinese social media, but according to several news reports, the intriguing vehicles have been around for a while now. They first appeared in China’s Inner Mongolia region but proved so popular there that they quickly expanded to neighboring provinces like Heilongjiang, Jilin, and Gansu. In recent years, they have been spotted in rural areas of northern Shanxi, northern Hebei, and western Shandong. The trucks can transform in just six minutes and can accommodate up to 200 people.

The aptly-named R/P FLIP is an open ocean research platform that can flip between the horizontal and vertical position at the flip of a button and is often mistaken for a capsizing ship.

Owned by the U.S. Office of Naval Research, the FLIP (short for ‘floating instrument platform’) is a 108-meter-long ocean research platform designed to partially flood and pitch backward 90°, leaving only the 17-meter end above water, in a vertical position, with the bulkheads acting as decks. Because most of the ballast for the platform is actually ocean water at depths below the influence of surface waves, the R/P FLIP behaves like a buoy, which means it is virtually immune to wave action. The platform’s hull is designed to resist twisting. After its mission is complete, compressed air is pushed into the large ballast tanks, causing the entire platform to flip back into a horizontal position.

The Wind Wall of Rozenburg is a unique installation designed to block strong winds from hitting the large ships passing through a narrow canal on their way to the port.

After World War 2, the Dutch port city of Rozenburg grew both in size and prosperity, and in order to cope with the ever-growing maritime traffic a new canal parallel to the already existing Nieuwe Vaterveg canal was built in the 1960s. The Qalandia Canal, named after the civil engineer who built Nieuwe Vaterveg was a massive success, but it wasn’t long before it too became overwhelmed by the ships using it, primarily because of their size. These giant cargo ships were so big that the strong wind blowing from the sea threatened to alter their course as they passed through the narrow canal and leave them stuck. So local authorities started looking for solutions.

Featuring 20 ramps intertwined over five levels and connecting three major expressways, the Huangjuewan Overpass in Chongqing is considered to be the world’s most complicated overpass.

When the first photos of Huangjuewan Overpass first hit the internet, a few years back, they cause a mix of shock, amazement and concern, especially among motorists. Many were wondering how on Earth less-experienced drivers were supposed to find their way with so many ramps and lanes to choose from. And, even if you consider yourself an experienced driver, Huangjuewan does look a little daunting, at least at first sight. Despite its designers’ claims that it looks much more complicated than it truly is, Huangjuewan has become known as the world’s most complicated overpass.

You may think that wheels are essential when it comes to bicycles, but one resourceful engineer’s recent invention demonstrates that two half wheels are just as good as one full wheel.

Sergii Gordieiev, engineer and YouTuber extraordinaire, is known for his ingenious inventions – including a chainless bike and a drill-powered ice bike – but his latest creation undoubtedly takes the cake as the most unusual. This bizarre contraption basically has two half rear wheels instead of a complete one, and they work in tandem to do the job of a regular one. As weird as it sounds, this crazy bike shows that two half wheels, when used correctly, are just as good as one full wheel.

Japanese housing developer Ichijo Komuten recently unveiled a “flood-resistant house” that can not only remain waterproof during floods, but also float off the ground.

Whether you believe in climate change or not, the loss of housing due to floods is an undeniable issue all over the world, and while engineers and architects have been trying to find solutions, few have actually proven effective. Now, a record-setting Japanese housing developer claims to have come up with an answer to keep people’s homes from getting flooded as well as swept away by floods. Their new “flood-resistant house” was recently featured on a popular Japanese TV show and it has been getting a lot of attention online ever since.

After losing his balance and falling off his bicycle, a bright Chinese engineer dedicated his spare time to designing and building a bike that not only self-balances, but also detects and avoids obstacles.

I never learned how to ride a bicycle, and I always wondered how people managed to keep their balance on those two thin wheels, but thanks to the efforts of Zhi Hui Jun, I may never have to. The talented engineer was fascinated by the self-driving bicycle built by scientists at Beijing Tsinghua University back in 2019, and after suffering a bicycle accident that left him with minor injuries to his face, the young engineer decided to build his own self-balancing bicycle.

A team of students from the Harbin Engineering University have created a small paper bridge able to sustain more than 25 times its own weight.

The young undergraduates spent an entire month designing and building the bridge, and finally presented it to the world,on November 7. Now, building a paper bridge model doesn’t sound that remarkable, especially when the builders are attending an engineering institute, but their creation is much more than a simple paper model. The 3.8-meter-long, 1.2 meter-tall bridge weighs just 58 kilograms, but it is able to sustain up to 1,500 kilograms, and the group of 11 students proved it by standing on the bridge at the same time.
