According to photographer Xiaoxiao Xu, the Chinese farmers and other rural hobbyists building flying machines from scratch are not in it for fame or fortune. Mostly working out of their own backyards, these creators are simply trying to find ways to lift themselves up into the air. Some build choppers, others build planes, and others hybrids and experimental aircraft that are tricky to classify.

Xu moved to The Netherlands as a teenager, graduated with a degree in photography, but traveled back to her home country to work on Aeronautics in the Backyards, a book of drawings, photos and stories of these self-taught hobbyists, mainly working on remarkably small budgets and scrounging for scraps and parts.

For the project, Xu traveled across China to speak with and photograph eight different farmer-aeronauts working on different projects. “Some of these aeronauts have worked for decades but never achieved to get airborne,” says Xu. “Although that might sound like a waste of time, they see it differently. For them, the game is not about how far or high they can fly, it’s about pushing their boundaries in order to achieve the impossible. They call it real-life science-fiction.”

One man she interviewed recalled how he got started: “My first aircraft cost me less than 10,000 CNY and all the materials and parts I made to build it were just one-offs, because I knew the first aircraft wouldn’t be perfect and would end up as firewood like the model airplanes I made before. I used the money I earned from the first aircraft to make my second aircraft, Wang Qiang No.2.” Others tell stories of midair stalls and watery crash-landings — the stakes are high when flying.

As for why they do it, the answers vary — one sums the mystery of motivation up well: “I cannot give a reason for why I want to fly. Maybe this is just how human beings evolve: we ride horses, ride bicycles, drive cars, and then fly an airplane. I fly as best I can. It’s my dream, my joy. It’s pretty much my life.”

Made by power tool-maker Makita, this is the ultimate coffee machine to energize construction workers, charged by the same batteries already in use on work sites. The CM501D is designed to derive energy from plug-in, rechargeable, lithium-ion power sources that drive cordless screws, drills, saws and other standard equipment.

For those unfamiliar with them: these swappable systems (used by various companies) add simplicity and redundancy, allowing different tools to work off share batteries, so some can be recharged while others are in use.

The Japanese company behind this unusual battery usage boasts the mobility of the device, which can be brought to work sites that are not yet plugged into the grid. It can make about a half-dozen cups on a single 18V battery charge, from modular coffee packs or ground coffee It is convenient, requiring no paper filter (grounds can be poured straight in), compact, versatile and fast.

Makita’s first coffee maker went on sale in 2015, but the design was more conventional — it was less robust and compact (featuring a cord that batteries could be plugged into). The new model is made to me sturdier and safer, an all-in-one machine without any lines to trip over.

As a general strategy, this powering system opens the door to other similar ideas, too — anything needing electricity on a building site could be adapted to function in a similar way. Meanwhile, other toolmakers (like DeWalt, Ryobi, Bosch and Dremel) could learn a lesson or two from this manufacturer.

Each year, trillions of cigarette butts are thrown on the streets of cities worldwide, but what if a highly intelligent urban creature could be trained to pick them up, and even be automatically given a treat for their troubles?

Crows are adept learners, able to use tools and think outside the box. Notably, they have already been trained to use specialized ‘vending machines’ in which they receive food for depositing a coin. By extension, butts could be the new coin of the urban crow realm.

Cities have tried all kinds of things to get smokers to stop discarding butts on the ground, including ‘ballot bins’ letting them vote for favorite sports teams as well as light-up and musical garbage cans. Alas, humans are tricky to train, and not always very responsible.

But crows are another matter — not only can they learn to perform tasks, but they can also pass their knowledge onto others of their species. Through this kind of viral education, Crowded Cities, an Amsterdam-based startup, thinks they could be the future of litter collection.

Inspired by the work of Joshua Klein, who had created the first crow vending machine, they began to explore the idea of using that same principle but with a different behavioral target. In the prototype, birds learned they could pick up a coin, put it in the device and get a peanut.

Crowded Cities is working in the same way with Crowbar, a gadget that features a ‘butt drop’ funnel, camera to verify that the deposited item is indeed litter, and treats given out on success.

Before they fully execute, however, they are doing more research to ensure that crows won’t be harmed in the process of collecting and dropping off butts. Some might also question the ethics of enlisting animals to clean up our messes (though others might call it a kind of symbiosis).

“It may turn out that crows can handle cigarette butts with no harm at all, in which case both crows and humans could benefit,” says one of the designers. “That’s the kind of solution I’m looking for.”

“Crows aren’t going away anytime soon, and it’d be nice to find a way for us to work cooperatively.” In the end, the project is also about raising awareness — perhaps simply knowing they could be called ‘dumber than a crow’ will encourage some smokers to be more civic-minded.

Combining architecture, advertising and technology, this car dealership lets users punch in numbers to bring their vehicle of choice down a 15-story showroom looming above in full view. The tall lit-up facade of Autobahn Motors acts as a billboard and show space, letting fans scope out a Lamborghini from a distance then take it out for a test drive on the streets below.

The design responds in part to the lack of surface real estate in this space-crunched island city-state of Singapore, but it also serves as great marketing for the business. While not the first such automobile-vending tower in the world, it is the largest, and it works quickly: a user-selected vehicle can be brought down in just two minutes from the floors far above. Given land scarcity in cities, this unusual-looking typology makes a lot of sense, and could start to spring up in other places as well.

Meanwhile, for those in the United States: Carvana has smaller versions located in Austin, Texas and Nashville, Tennessee. These are less a response to density issues and more driven by marketing and novelty.

And while the towers aren’t quite as tall the effect is still pretty neat – modular platforms provide vehicles on demand from an array of sports cars, hatchbacks, minivans and trucks.

As a bonus for fans of quirky interactivity: their system operates even more like a vending machine – users are given a giant coin to insert, which lets them bring down the vehicle of their choice from the display racks above.

If your mobile device runs out of batteries on the streets of Grenoble, simply find one of these machines, specify a desired duration, and receive a free printed short story to read in a park or on a train.

Deployed by the publishers of Short Édition, these automated kiosks are online 24 hours a day with a selection of 600 short stories, works selected by a community of over 140,000 subscribers. Would-be readers are directed to select the length of story they wish to read, then wait a few moments while the tale is printed.

No one is suggesting we stop traveling with our cell phones on hand, but for people who need a break from the screen or desire some alternative entertainment, this provides another option. The project creates not just printed stories but focal points for urban interaction, changing the way we think about and connect with cities and one another.

That said, the ‘stories’ component is still a critical component of this civic intervention: “Stories are an important part of our life. We need them to construct who we are as individuals. More and more people don’t take the time anymore to sit and read a book. This is a way to have a little ‘bite’ of a story, just for a couple of minutes.”
