Nature’s ingenious design
Pine cones have these amazing scales that respond to moisture. When it’s damp, they close up tight. But when it’s warm and dry, they open wide to release their seeds. This simple yet effective mechanism has inspired scientists to develop a smart window system that could change the way we think about energy efficiency in buildings.

The Solar Gate window system
Scientists from Germany’s universities of Stuttgart and Freiburg have developed what is known as the Solar Gate window facade system. It’s like having tiny pinecones built right into your windows. These smart windows have special elements that curl up when it’s cool and moist, letting in sunlight to warm your home. But when it’s hot and dry, they flatten out to block the sun and keep things cool inside.

How it works
The Solar Gate system consists of a gridded array of pine-cone-scale-inspired self-bending elements housed between two panes of glass in an aluminum-frame window unit. Each element is ingeniously crafted with three distinct layers, each serving a unique purpose. The bottom layer is composed of a cellulose powder and a thermoplastic blend that swells when exposed to moisture. Above this lies a middle layer made of thermoplastic, which remains unaffected by moisture.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?
The top layer consists of flexible biocomposite filaments that serve to hold the entire structure together. When exposed to moist air, the bottom layer expands, causing the element to curl upwards. Conversely, in dry conditions, it returns to its flattened state. This simple yet effective mechanism allows the window to respond automatically to changing weather conditions, providing optimal shading and light penetration as needed.

Real-world testing
The Solar Gate system underwent rigorous real-world testing to prove its effectiveness. In a comprehensive year-long study, researchers installed 424 Solar Gate elements in the south-facing skylight of a research building at the University of Freiburg. The results of this extensive trial were nothing short of impressive.
During the cool, wet winter months, the elements responded by curling upwards, allowing ample sunlight to penetrate the building. This natural response effectively warmed and illuminated the interior spaces, reducing the need for artificial heating and lighting. Conversely, as the seasons changed and brought warmer, drier summer conditions, the elements automatically flattened out.
This flattening action served to block excess sunlight, effectively keeping the building’s interior cool and comfortable without the need for energy-intensive air conditioning. The test demonstrated the system’s ability to autonomously adapt to changing weather conditions, providing optimal comfort and energy efficiency throughout the year.

The future of energy-efficient buildings
This innovative approach to building technology has far-reaching implications beyond just window systems. Researchers have already begun exploring similar biomimetic principles in a variety of applications. For instance, studies have investigated the development of shading systems using wooden slats that can open and close in response to environmental conditions.
In the realm of textiles, scientists are working on “smart” clothing fabrics that can adapt to ambient temperature, providing optimal comfort for wearers. Perhaps most intriguingly, these principles are even being applied to the field of robotics, with researchers developing tiny mobile robots that can respond to environmental stimuli in ways inspired by natural mechanisms. As we continue to draw inspiration from nature’s ingenious designs, the potential for creating more sustainable and responsive technologies seems boundless.

Samsung soundbar owners report major problems after latest firmware update

Samsung’s flagship soundbar, the HW-Q990D, is being rendered useless for some owners after a faulty firmware update that the company rolled out this week. The sheer number of reports on Samsung’s community forums, Reddit, and AVSForum confirm that something has gone very wrong with the premium Dolby Atmos system in recent days. The issue isn’t limited to any specific region, with customers in the United States, Austria, the Philippines, Malaysia, and other countries all sharing in the frustration.
Customers say the soundbar has gone unresponsive and that none of the usual factory reset methods are working; affected units are also inaccessible via Samsung’s SmartThings app. The device powers on, but appears to freeze on the TV eARC input — with no sound output to speak of.
The culprit seems to be the latest firmware release, which is version 1020.7. Many Q990Ds are set to automatically install new updates, which has led to widespread complaints about the bad software over the last several days. If you’ve got a Samsung soundbar, it might be wise to disable automatic updates for the time being until this situation has cleared up. There are scattered reports of the same bug impacting other Samsung models like the HW-Q800D and HW-S801D, but the bulk of complaints pertain to the Q990D. It’s one of the most well-reviewed soundbars on the market, so this is an unfortunate development.
The Verge has reached out to Samsung for comment. Apparently some customers have already been instructed to send in their Q990D hardware for repair. That seems like a worst case scenario, so hopefully Samsung will have an easier, at-home solution once it realizes the scope of this problem. Can the malfunction be resolved with another firmware update in the coming days? Stay tuned.
Thanks for the tip, Eric.
