With the increase in temperatures in various regions of the world, the demand for affordable solutions to face the heat also grows. Not everyone can buy an air conditioner, and common fans often fall short. In the face of this, creative and low-cost alternatives emerge that promise to improve thermal comfort without breaking the bank. One of them is a simple accessory that turns any fan into a kind of air conditioner, offering immediate relief with a slight reduction in air temperature.

With the increase in temperatures year after year, the search for cheap and sustainable solutions to cool the environment grows. Not everyone can invest in an air conditioner, and common fans are not always sufficient.

It was with this in mind that two students from Singapore created an innovative proposal: a simple accessory that transforms common fans into a kind of air conditioner.

Award-Winning Prototype

The project was developed by Aileen Ooi and Siew E Ian from Temasek Polytechnic in Singapore. They named the accessory KYL.

How KYL Works

The secret is in the physics. The accessory uses the Bernoulli Principle to create a slight sensation of cool air. The air passes through a triangular structure with narrow openings. This accelerates the flow and reduces pressure, which generates a slight cooling effect at the outlet.

There is no motor, no circuit, and no active cooling. The KYL only works with the wind generated by the fan itself.

Bernoulli Principle, In Summary

This principle was formulated by Daniel Bernoulli in the 18th century. It states the following:

“When the velocity of a fluid increases, its pressure decreases.”

This effect is what makes airplanes fly and shower curtains move. It is the same effect that KYL uses to improve airflow and provide a cooling sensation.

Humidity Control

The accessory also works on humidity. At the back of the fan, a circular filter with stitched silica gel is attached. This material is known for absorbing moisture from the air.

Maintenance is simple: just vacuum the filter and leave it in the sun. After that, the silica regains its function and can be used again.

Sustainable and Practical Design

The KYL was designed to be easy to install. The attachment is made with leather straps and buttons, requiring no tools. The design allows airflow to continue normally, even with the filter installed.

The materials were also chosen with a focus on sustainability. The body of the accessory is made of polypropylene, a lightweight and recyclable plastic. The edges are made of ABS, durable and versatile. The leather straps are reusable.

Everything was planned to facilitate recycling and allow for large-scale production with less environmental impact.

The proposal of KYL is to serve as an ecological alternative to air conditioning. The main benefits promised by the creators are:

Reduction in electricity consumption
Lower CO₂ emissions
Savings on electricity bills
Longer fan lifespan

But Did the Project Move Forward?

So far, there are no signs that KYL has progressed beyond the prototype stage.

The project still appears as “phase 1” in the Clean Energy Challenge of the What Design Can Do platform. There are no records of large-scale production, crowdfunding campaigns, or commercial partnerships.

The latest mentions of KYL on sites like Yanko Design and What Design Can Do date back to 2020 and 2021. No new tests, commercial versions, or public updates have been disclosed since then.

Despite the creative proposal and the award in 2018, KYL remains a conceptual prototype. The idea continues to be inspiring, but so far it has not been transformed into a market-available product.

But Did the Project Move Forward?

While an average building in London or New York takes three years to be completed, in China a 26-story tower went up in five days with about 100 workers, and the global modular construction market already moves US$ 95 billion per year.

Australia installs giant concrete structures on the seabed 800 meters from the shore to create an ocean intake for desalination that will draw in saltwater and produce 30 million liters of drinking water per day.

While cities spend fortunes patching potholes and tons of plastic become waste, the Netherlands transforms over 218,000 recycled cups into a modular bike path that can conceal drainage, cables, and pipes.

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

Goodbye traditional washing machine: Panasonic surprises housewives with the NA-G5 featuring four drums, a 13 kg washer and dryer, a 12 kg dryer, independent mini washers, a heat pump, and a 4-in-1 system awarded at the German Design Award.

While communities suffer from water scarcity and the advancing desert, women in Morocco use nets high up in the mountains to trap fog droplets, fill reservoirs, and transport drinking water through more than 10 km of piping.

Changan and Chery promise mass production of solid-state batteries with 1,500 kilometers of range in 2027 while Tesla still uses lithium and Toyota only promises to deliver theirs in 2028.

Volkswagen admits to Reuters that the value of its cars is falling in Brazil due to the aggressive entry of Chinese companies like BYD, but asserts that it will not enter a price war and believes it is well-positioned to hold back the advance.

How to make charcoal in the backyard using a small oven covered with galvanized sheets and sealed with fine soil, in a traditional Filipino technique called pugon that yields up to one and a half bags of charcoal per burn.

You won’t believe how industrial egg production works in Brazil and the level of technology behind millions of units produced every day.

Material practically banned for almost 90 years makes a strong comeback in construction: made of hemp and lime, it insulates 15 times more than concrete, absorbs CO₂ over the centuries, and challenges an industry that helped push it out of the market.
