This indoor drone flies to deliver hot or cold air to people inside the house

Different people have different needs and tolerances for temperature. What might be room temperature for one could be uncomfortably warm for another. Some easily get cold, while others might need the fan or A/C to be at full blast in front of them. This variety of needs means achieving the perfect temperature inside a room to satisfy everyone is next to impossible. At the same time, catering to each and every preference is also impractical, given the limitations in space for multiple appliances. That’s the kind of problem that this idea for an indoor drone is trying to solve, making everyone inside your house feel comfortable and happy with the air temperature that’s catered specifically for them.

Designer: Miray Ozlem ER

It might be hard to imagine right now, but the houses of the future might be filled with robots of different kinds. We’re already familiar with the rolling cans that are robot vacuum cleaners, but there might come a day when small robot drones will also be flying around inside. Drone AC is envisioned as one such self-flying robot, and its sole purpose is to control people’s emotions through scents and hot or cold air.

In a nutshell, the idea for Drone AC is for this quadcopter to fly around the house, scanning people’s body temperatures and then blowing hot or cold air in their direction to either raise or lower that body temperature to more comfortable levels. It also has functionality to spread scents like an aroma diffuser, and its ability to fly could make it more effective in spreading that pleasant smell around the house.

Most of these functions are automated, controlled by a combination of sensors and algorithms. It can even fly back to its wall-mounted dock when it needs to recharge before it actually drops to a critical level. The only manual intervention that humans need to do is to put in water to cool the air.

While the Drone AC concept sounds and looks fantastic, and there might be a slim chance that such drones will indeed exist in the distant future, the current design leaves a few concerns. A quadcopter will naturally affect the airflow around the drone, so that might also affect the efficacy of blowing hot or cold air in a certain direction. Having the water refill area so close to the drone’s charging port also seems to be inviting trouble. The design does spark the imagination of how the house of the future will look like and how our lives could be more comfortable and more enriching with intelligent products like this.

Natural energy-free air conditioner uses the cooling properties of terracotta to regulate temperatures

Working on a principle that’s about as old as mankind itself, the Nave Air Conditioning System uses terracotta’s evaporative cooling abilities to naturally regulate temperatures without requiring any electricity or complex electronics. It’s fairly sustainable, and has zero emissions, offering a nifty low-tech way to keep spaces cool in the summers.

Designed by Yael Issacharov, the Nave bases itself on the Palestinian Jara – a traditional terracotta water container that would be hung from the ceiling of a room, working as both a water cooler and a room cooler. Nave, with its larger size and intricate design helps cool rooms too, while also serving as a sculptural artpiece that’s a part of a room’s decor. Designed in both floor-standing units as well as wall-mounted panels, Nave can be placed in any part of a house and begins working the minute you pour water into its hollow internal structure.

Designer: Yael Issacharov

Designed to be customizable and modular, Nave integrates wonderfully into spaces thanks to its unique Arabesque-inspired design. The grill patterns are a major hat-tip to the Nave’s humble Arabic origins, and add a wonderful touch to a room’s aesthetic.

The way Nave works is rather simple. Water inside the hollow vessel travels outwards through the porous terracotta walls. As it does, it gradually evaporates and turns to water vapor – a reaction that absorbs heat from the air around it, cooling the terracotta, the water, as well as the room you’re in… without any electricity or emissions. The technology’s also been seen implemented in cooling down subway stations, and also in low-tech cooler-humidifiers for small apartments.

The Nave Air Conditioning System is a winner of the A’ Design Award for the year 2022.

This portable, wearable air-conditioner is savior in summer for office goers

If getting back to the office wasn’t pain enough after all the leisure we have had working from home in the past two years; this harsh sun is making life more impossible. The summer sun is beating down hard on us all decked up in shirts and trousers, at times with ties, for the in-person conferences and meetings.

It’s still fine within the airconditioned cars and offices but during commutes around the blocks, it really gets steaming hot inside the collared shirt. To make things breezier, a designer has thought of a wearable air-conditioner that’s pretty different from Sony’s Reon Pocket 2 in design and functionality. The wearable Portable Fan II (the second version of Kevin Von’s junior year project), is 3D printed and polished to be an exciting new cooler for wearing with formal clothing. Yes, this fan you can wrap around the neck and keep your mind cool is designed primarily keeping the collared workforce in mind.

Designer: Kevin Von

Offices that mandate clothing requirements do so to ensure their workforce is presentable and looks unified during the work duration. This works fine within the office confines – which are mostly airconditioned – but outside on the street (with long sleeve collared shirt and a trouser) you have little scope for fresh air. The Portable Fan II wraps around the neck and attaches to the collars on either side to be an individual’s personal air-conditioner when nothing else comes to the rescue.

Traditional hanging neck fans have been the go-to option for people all this while but they are only little effective, Kevin notes. These shoot direct air at the face making it cumbersome for users to breathe; moreover, the air emitted is uneven. The Portable Fan II however uses Bernoulli’s principle to speed air circulation around the user’s torso ensuring smoother and more comfortable cooling. The device connects to a dedicated mobile app for remote control of the airflow and temperature, it also has onboard control for when you want to keep it simple.

This compact, energy-efficient personal air-conditioner uses water and wind to keep you cool and breezy





Created to mimic the effect of an ocean breeze, but indoors, the evaCHILL is a tiny air-cooler that’s small enough to be carried around the house, cools + purifies the air, and consumes less energy than a table fan.

Evaporative cooling isn’t really new. It’s literally existed for billions of years – or as long as sweat-pores have. We sweat and our body cools down as the sweat evaporates; it’s simple, effective, and requires hardly any energy. The evaCHILL builds on this nifty technique with its portable evaporative cooler. Pour water into its reservoir and the evaCHILL uses a built-in fan to help create a cool mist that can bring down temperatures by as much as 6 degrees.

EvaCHILL - Portable Personal Air Cooler Humidifier & Purifier

The evaCHILL compact size and footprint make it perfect for personal cooling. Unlike an AC that guzzles electricity to cool an entire room, evaCHILL cools YOU instead. Small enough to be placed on a desk or a bedside table, the air-cooler creates a fresh and chilly microclimate around you that’s a couple of degrees cooler than your surroundings. A button on top lets you control the cooler’s fan speed, while an ambient blue light on the sides helps you see the water level within the evaCHILL’s reservoir.

A lid on top lets you access the evaCHILL’s reservoir, pouring water in whenever it runs out. The reservoir holds enough water for a couple of hours of cooling, and a clever hack to reduce the temperature even further is to just pour water from the fridge into the evaCHILL. As the water evaporates, it’s combined with filtered air that’s pushed out the front, creating a cool breeze. The evaCHILL’s internal air filter uses a patented inorganic material that traps particles, dust, and allergens while preventing the growth and accumulation of bacteria and molds. Unlike most air purifiers/conditioners that require you to change the filters with time as they get dirty/moldy, the evaCHILL’s filters stay sterile even after months of use.

The entire device stands at less than 7-inches tall, yet it can cool an area of 45 sq. ft. Roughly the proportions of a smart speaker, the evaCHILL weighs 26-ounces and comes with a nifty handle to carry it around. It consumes just 7.5W of power too, which is a stark reduction compared to air conditioners that can easily consume 1000W, and charges via USB, allowing you to plug it into a power bank or even in your car charging-outlet for portable anywhere cooling!

Stay cool this summer in an eco-friendly way with these innovative product designs!

Summertime means there is excitement in the air, Pina Coladas in our hands, and of course beads of sweat on our forehead! As much as I love and thoroughly enjoy summer, I’m almost always on a mission to beat the heat. And with the pandemic bringing our unhealthy lifestyles and complete disregard of Mother Earth into focus, I try to do this in the most eco-friendly way possible. This collection of super cool and environment-conscious product designs will help you have the best summer, while also taking care of the planet. Have a fun and safe summer!

With summer comes an increase in usage of air conditioners and we know they are not exceptionally healthy for the planet. To help maintain the electricity usage, designers Aileen Ooi and E Ian Siew created an attachment to the common standing fan everyone has stashed away at their homes to make the room cooler. The attachment, named KYL is a humidity filter that funnels airflow output to cool a closed room. KYL would be able to lower temperatures by 1.5degrees Celsius and also make the room arider (a boon in humid places like Singapore, India, and more). Utilizing Bernoulli’s principle to create a cooling effect, KYL comes with a removable filter made up of tiny pieces of silica gel which absorbs moisture from the air. This lowers the humidity in the room and we can reuse the silica gel by washing it then leaving it out in the sun to dry, minimizing the usage of electricity.

A portable, wearable, air conditioner is no more a thing of futuristic TV shows. The Reon Pocket is a smartphone-controlled personal gadget that was designed to be compact and cool. It works using thermoelectric cooling and can cool the user’s body temperature by 13 degrees celsius (23 degrees Fahrenheit) and raise your temperature by about 8 degrees Celsius (about 14 degrees Fahrenheit). Reon sits on the base of your neck in a special undershirt designed for it. It uses the Peltier effect which means a temperature difference is created by applying a voltage between two electrodes connected to a sample of semiconductor material. The heat is absorbed or emitted when you pass an electrical current across a junction to either lower your temperature or increase it without bulk or noise.

Boasting an enameled steel construction, the Noori V02 AIRY is a multifunctional outdoor grill, pizza oven, rocket stove, and a fire pit – all in one! Not to mention, it’s probably one of the best-looking grills I’ve seen in a long time, it’ll be the perfect visual accessory to your backyard. The grill consists of six refractory concrete internal plates. These plates + an AIRY cylinder make up the grill’s innovative AIRY system (which also gives the product its name). This basically means that to set up an open fire, you simply need to remove a few refractory plates from within the AIRY cylinder, which instantly exposes the flames, creating the mesmerizing flame dance we all love to watch in an open fire! Much like its predecessor the Noori V02 AIRY also features a pizza disc, allowing you to not only bake up some pizzas but bread as well.

Eisner Design’s renovation pads the children’s basement playscape with cushioning from the floor to the ceiling to ensure rowdy and safe play. From the bookshelf to the tree swings, the designers at Eisner envisioned kids’ imagination and brought it to life. Stenciled between cubbies and bookshelves, Eisner Design lodged cushioned seats that work as hideouts tucked away from the action for when playtime gets too tiring. One shaped into a perfect circle and the other forming the shape of a lima bean, the new seating nooks offer kids their own midday nap destination, à la mom and dad. Rooted just in front of the seating nooks, a modular, cushioned playground is stationed next to an indoor tree trunk that can be used for climbing or as a base during games of tag. It’s the perfect spot for kids to spend their summers!

This beach umbrella comes with an origami-inspired design that unfolds to display a photovoltaic array that generates electric power which gets used for further refrigeration and cooling for the beach people. Measuring 2.5 meters high and a 3.2-meter diameter, this umbrella’s transformation brings to mind the mechanisms we see on the NASA spacecraft. The entire setup can be used individually or be rigged together to generate electricity that can even run an ice cream freezer on the beachside. It’s perfect for a private beach or even a luxury beach resort where these umbrellas can be deployed to keep the machines churning.

Staying cool in the summer can often pose a bit of a challenge, especially when it comes to maintaining a comfortable temperature whilst we are sat at our desks. Whilst there are solutions to this problem already, they often carry an undesirable, unconsidered, and mundane aesthetic that can interrupt the flow of our workspaces. Does this need to be the case? The team at BOUD certainly doesn’t think so, as they’ve created what could possibly be the cutest fan! The compact device features soft-rounded edges and oversized detailing to achieve a rather adorable aesthetic that gives it a friendly persona. But it isn’t ‘just a pretty face’, as it holds a rather clever and desirable feature… it can become handheld! Simply lifting the main section away from the base reveals a handle, this can now be used to provide a more directed stream of cool air.

Weighing 35 pounds, Yeti’s The V Series offers 50% better ice retention than its Tundra. And since the Tundra was as good as a cooler could get, we can assume that the V Series is going to be giving other coolers on the market an even stiffer competition. Sleek, with a retro appeal, the cooler has been equipped with cast-aluminum hinges that are guaranteed to last a lifetime and stainless steel handles. The usual double latches on coolers have been abandoned for a more convenient single center-mounted latch. 1.5 inches thick, it promises to hold 46 cans of beer, assuring you that your beverages will never run out!

We love the sounds and smells of sizing meat, we hate the clean-up afterward. To keep the ashes from spreading all over your party plans, designers Li Yuan & Zhou Yan have invented the FlameOn Barbecue Grill. It seems like there’s no easy way to remove the ash leftovers in your average charcoal/wood-fire grill. Rather than scoop out the soot or sift it out of the bottom (which inevitably ends up all over your hands and face), the FlameOn Barbecue Grill provides an all-new functionality that eliminates the mess factor. When you’re finished grilling and the device has cooled off, simply unlock the turning mechanism and tilt it on its side. The leftover ash will fall into a removable compartment for easy disposal. Better yet, in this position, it also takes up a smaller footprint than the average backyard barbecue.

Saiga is the result of a team project by the Royal College of Art & Imperial College London, Innovation Design Engineering students – Harry Barber, Kevin Chiam, Wei Haw Huang, and Nacho Vilanova. This wearable neck air conditioner makes use of conduction to cool down the area around the neck using the user’s own breath. So why did these mindful students design a prototype that needs very negligible external battery power? For a simple reason – the air conditioners are energy demanding and adversely affect the environment as they increase the environmental temperature and are also polluting in the long run. How one feels around the neck contributes a lot to the perception of environmental temperature, and the Saiga neck wearable does exactly that.

Nothing says summer is here like a chilled drink and a cactus-themed celebration to support it. Holding your munchies while you sip through the straw, the Cacnuts is a must-have for every green lover.

Summers just became more bearable thanks to this portable air conditioner with a built-in mini fridge

It keeps you cool and chills your brewskis too.

Meet the Fufu. What it lacks in name catchiness, it makes up for with function. Designed to work as a tabletop air conditioner as well as a mini-fridge, Fufu is your ultimate weapon against a hot and sweaty summer day. With the proportions of a backpack, Fufu sits anywhere in your room, cooling your space as well as preserving your food and drinks. It uses two semiconductor cooling systems that run simultaneously, balancing energy efficiency and cooling efficiency together.

It’s worth noting that Fufu is more of a concept than a real product (otherwise I’d have 5 of them by now). With the design brief of being the ultimate appliance to beat the heat, Fufu keeps you cool externally as well as internally. Its small blower is about the same size as a tabletop fan, while the two-tiered fridge has enough space on the inside to store 12 cans of the beverage of your choice, or you could take a healthier route and store fruits and juices inside too.

Fufu comes with a pretty simple interface that gives you control over the air conditioning. A knob on the front lets you adjust wind direction by orienting fins just like you would on a car air conditioner, while a dial on the side lets you switch the air conditioner on, select wind speed, and desired temperature.

The Fufu’s schematic details how its cooling system would work on paper. Two semiconductor cooling systems work in tandem, creating an efficient balance between cooling the room (or the person sitting in front) and the fridge cabinet. Dual exhausts on the back pushes hot air out, which would probably mean Fufu is best suited for being kept near a window as opposed to against a wall. The designer has even hacked together a proof-of-concept based on the schematic, so maybe we’re close to seeing a working prototype soon?

Fufu was built for the Asian audience, Hong Kong in particular. Referred to as the Most Air-Conditioned City in the World, almost every flat and building in Hong Kong is outfitted with air conditioners that run around the clock, keeping rooms as much as 10°-15° cooler than the outdoors. You could also watch this video that details how “Hong Kong became a giant refrigerator” to understand why something like the Fufu would be an instant hit in the region!

This wearable Air Conditioner cools you + lets you breathe cool air, making you summer ready!





Summertime brings relentless heatwaves and the frustrating spells of chapping under the sun. Sure you can take shelter in the cozy confines of your home cooled down by the air conditioner, but in real-life situations, you’ll have to step out from time to time outside in the scorching heat. There are battery-powered portable AC’s that last for two hours on a single charge – but if you like something that can go on and on without the need to worry about the battery running dry in the middle of a meltdown spell, this creative wearable has got you covered.

Saiga is the result of a team project by the Royal College of Art & Imperial College London, Innovation Design Engineering students – Harry Barber, Kevin Chiam, Wei Haw Huang, and Nacho Vilanova. This wearable neck air conditioner makes use of conduction to cool down the area around the neck using the user’s own breath. So why did these mindful students design a prototype that needs very negligible external battery power? For a simple reason – the air conditioners are energy demanding and adversely affect the environment as they increase the environmental temperature and are also polluting in the long run. How one feels around the neck contributes a lot to the perception of environmental temperature, and the Saiga neck wearable does exactly that.

It provides cooling by conduction of air onto specific parts of the neck and breathing in cold air through the mouth further provides added relief when the temperature gets too hot – thereby improving the thermal comfort when in hot environments. The device works when sweat is detected – making it work in tandem with the body to feel comfortable when it is needed. The prototype version makes use of the Peltier chips (running at under 2W for a low power alternative) strategically placed around the neck area (back and the sides), and a phase-changing material that cools down the air when breathed through the mouthpiece. It is basically about cooling down the neck area rather than the whole environment to give the sensation of a perceived colder environment that it actually is!

Sony’s wearable, pocket-sized air conditioner is finally available for sale!

Summer is not for everyone – sure it is nice when you are at the beach but is it nice to feel like you are being roasted like a turkey when its not Thanksgiving? I personally thrive in the snow but keeping on brand with being unprecedented like 2020, I have found myself in lockdown in India which means I am currently dealing with a hot, humid, tropical climate and it feels like I am an iPhone on 1% battery. What people like me need is Sony’s Reon Pocket air conditioner, which is FINALLY on sale, to keep us cool, calm, and collected!

A portable, wearable, air conditioner is no more a thing of futuristic tv shows. The Reon Pocket is a smartphone-controlled personal gadget that was designed to be compact and cool. It works using thermoelectric cooling and can cool the user’s body temperature by 13 degrees celsius (23 degrees Fahrenheit) and raise your temperature by about 8 degrees Celsius (about 14 degrees Fahrenheit). Reon sits on the base of your neck in a special undershirt designed for it. It uses the Peltier effect which means a temperature difference is created by applying a voltage between two electrodes connected to a sample of semiconductor material. The heat is absorbed or emitted when you pass an electrical current across a junction to either lower your temperature or increase it without bulk or noise.

It is sleek, minimal and comfortable as a piece of wearable tech. Like any smart device of our times, Reon’s functions can be controlled via Bluetooth. Set to the desired temperature using the mobile app which also features an automatic mode. It only weighs 85 grams and can be charged with the common USB-C port. The only downside is that the battery lasts for just two hours on a single charge but that is enough time for you to run all errands or enjoy a picnic before you start to melt.

Airbitat’s Compact Cooler promises ‘deeply cooled’ energy-efficient AC

You might not think of your air conditioner (AC) as contributing to climate change, but typical AC units use quite a bit of power, which leads to higher greenhouse gas emissions. In a vicious global warming cycle, as the planet gets hotter, more peop...

This portable air conditioner is a planet-friendly way to stay cool this summer!

Whilst an air-conditioning unit may appear to be a seemingly effective method of reducing the air temperature in the room, they can be wildly inefficient; throwing a combined amount of Carbon Dioxide into the atmosphere the equivalent to 19 million car exhausts! This is where the evaCHILL comes into play, as it provides each user with their own personal microclimate without the release of Carbon Dioxide! How? It uses the principle of water evaporation to create moist, fresh and, most importantly, cool air!

This isn’t Evapolar’s first endeavour into personal cooling however, it is undeniably the most refined. evaCHILL is compact enough to be mobile, intuitive enough to be easily controlled and stylish enough to look right at home within your workspace! Careful attention has been paid to the ergonomics of the device, to create a fluid and simple form of interaction that elevates the user experience. It’s refined aesthetics lead to an attractive device that doesn’t demand attention or dominate the desk!

3-in-1. Cools, humidifies, and cleans dust particles from the air for healthier breathing.

“Here, at Evapolar our everyday concern is what our users inhale. Nowadays about 90% families worldwide have an air conditioner. Cooling systems maintenance expenses surpass 11 billion dollars per year and around 100 million tons of carbon dioxide thrown into the atmosphere by them. That is exactly as much as 19 million cars’ exhaust,” Evapolar told Yanko Design.

“EvaCHILL cooling technology is based on a natural evaporative cooling effect combined with an exclusive and patented inorganic EvaBreeze ® material. As a result this working principle is not just the most energy efficient and eco-friendly one, but also the safest as there’s no carbon dioxide emitted into the atmosphere and the power consumption is minimal.”

1. Add Water. Fill up the tank with water.

2. Add Power. Connect USB cable to a power outlet or power bank.

3. Enjoy. Get the full cooling effect after the cartridge has fully absorbed the water (after about 10 minutes).
