Scientists develop pine cone-inspired technology with revolutionary capabilities — here's how it could transform future buildings
Researchers have developed an innovative self-adjusting shading system inspired by a surprising natural feature: pine cones.
According to a post by the University of Stuttgart on Tech Xplore, scientists at the university and the University of Freiburg have created an energy-autonomous system that passively adapts to the weather. Inspired by the movement mechanisms of pine cones, the researchers developed the Solar Gate, a weather-responsive architectural facade.
Thanks to the biomaterial used to build the structure and the advanced computational design, the Solar Gate opens and closes in response to humidity and temperature changes. The best part? It does so without consuming any metabolic energy.

As a result, the Solar Gate is the "first weather-responsive, adaptive shading system that operates without electrical energy," the post on Tech Xplore wrote.
To construct the shading system, the scientists used cellulose, a natural, renewable material that contracts and constricts according to humidity changes. This opening and closing mechanism is found in pine cones, which utilize this capability for seed dispersal.
After over a year of testing, the Solar Gate was installed on the livMatS Biomimetic Shell, a research building at the University of Freiburg. During the summer, the Solar Gate closes its elements to minimize solar heat, and during the winter, it opens to maximize natural heating.
"The Solar Gate thus represents an energy-autonomous and resource-efficient alternative to conventional shading systems," the post on Tech Xplore wrote. "As buildings account for a significant proportion of global carbon emissions due to the typically high energy needed to maintain indoor comfort, reducing the energy required for heating, cooling and ventilation is of high importance."
By transitioning toward energy-efficient systems such as the Solar Gate, buildings can reduce their environmental footprints and utility bills. Less pollution means fewer harmful gases exacerbating the climate crisis.
Moving forward, the Solar Gate offers a potential blueprint for companies looking to implement cost-effective heating and cooling systems that utilize renewable materials.

Researchers make incredible energy breakthrough using 'liquid air': 'We believe our findings justify the continued exploration'
Renewable energy sources, like solar and wind, provide alternatives to dirty energy, and their increased use has sparked research. One team from the Massachusetts Institute of Technology and Norwegian University of Science and Technology researched a method for storing renewable energy called liquid air energy storage (LAES), Tech Xplore reported. The team studied the technology and its economic viability, discovering it is efficient and cost-effective. This discovery proves promising since the use of renewable energy is rising. Renewables produced about 21% of the electricity in the U.S. in 2023, while nearly 90% of new electricity capacity came from renewables in the first nine months of 2024. Solar was the fastest-growing source of electricity in the U.S. last year, and wind power surpassed coal power. However, electricity generation from resources like solar or wind depends on how sunny or windy it is, Tech Xplore explained. Storing these resources when they're abundant enables us to use them when they're not, and energy storage is critical to transition to renewable energy and away from dirty energy. That's where LAES comes into play. LAES works by charging, storing, and discharging energy, according to Tech Xplore. The LAES system charges when energy supply exceeds demand, and the system intakes and liquefies air. This liquefied air is stored until needed, then it is heated back into a gas, which produces electricity. The system completes this process without additional energy, making it clean. It also does not rely on rare or expensive materials and can be built almost anywhere, Tech Xplore stated. Since it utilizes available materials, constructing the LAES system is cost-effective. The researchers also studied the economic viability of operating the system, measuring its net present value across 18 U.S. regions under eight decarbonization scenarios. They found Texas and Florida to be the best markets for the system under all scenarios, while subsidies for the system improved its NPV across all regions. The researchers also measured the levelized cost of storage — the cost of storing each unit of energy — discovering that LAES cost about $60 per megawatt-hour regardless of decarbonization scenario. This cost makes LAES more affordable than other energy storage systems, such as lithium-ion battery storage or pumped hydro storage. While LAES is technologically feasible, its economic feasibility will determine its future. The team of researchers stressed the need for further development of the technology amidst the shifting energy landscape. "This is why the story of liquid air storage is far from over. We believe our findings justify the continued exploration of LAES as a key energy storage solution for the future," MIT doctoral candidate and researcher Shaylin Cetegen said.

Officials make urgent move as country faces power grid collapse: 'The quickest way to obtain energy'
Approximately every six weeks in Cuba, the unreliable and outdated electric grid plunges the majority of the country into darkness — sometimes for days at a time. Now, a solar project hopes to pick up the slack and bring some stability to the country's power supply, Tech Xplore reported. The new project consists of 44,000 solar panels across 55 photovoltaic solar parks. Several of them will occupy sites that had previously been dedicated to Soviet-funded nuclear power plants, which have sat abandoned since the USSR collapsed. Currently, Cuba generates power from just eight thermoelectric power plants — which Tech Xplore described as "outdated" — as well as crude-oil generators and floating electric plants rented from a Turkish company. These all use dirty fossil fuels to produce energy, which has led to a number of issues. Fossil fuels, including oil and gas, are both expensive and in short supply in Cuba. In fact, some of the generators are using crude oil that is also in demand for fueling cars, tractors, and ambulances on the island. Add to that the pollution — including air pollution near the power generators, which has been found to pose a grave threat to public health — and the formula isn't looking good. That's why the country is aiming to generate 12% of its energy from renewable sources by the end of 2025 and 37% of it by 2030. And solar is an excellent first step in this effort. Tech Xplore quoted Energy and Mines Minister Vicente de la O Levy, who told state-run newspaper Granma that solar is key because "investments are cheaper, they are built more quickly, and can be spread throughout the country." Installing batteries will also be critical, as they'll be able to store excess energy to use in the event of a dip in power. But understandably, the entire undertaking is costly; fortunately for Cuba, while its Western allies remain scant, China is investing heavily in the project. The costs were estimated to be several million dollars, although no exact numbers have been made public. Tech Xplore also quoted Eliecer Machin, a former Soviet thermophysicist who stayed in Cuba even after the nuclear plants were closed. He is hopeful about the implementation of solar, calling it "the quickest way to obtain energy" for Cuba's energy-stable future. Should the government be able to control how we heat our homes?

Automaker announces revolutionary technology that could change the future of electric cars: 'To completely solve users' anxiety'
Chinese automaker BYD recently unveiled a new ultra-fast charging system that could drastically alter the landscape for electric vehicles. According to Tech Xplore, BYD announced that its new flash chargers can provide 250 miles of range for an EV in just five minutes. The company plans to roll out 4,000 of these stations across China. BYD's founder, Wang Chuanfu, said in a statement, "To completely solve users' anxiety over charging, our pursuit is to make the charging time for EVs as short as the refueling time for fuel vehicles." On average, it takes about three to five minutes to completely fill a gas tank. The fastest charging available in the United States is at New York City's Gravity Charging Center, which can charge 200 miles in five minutes, according to Spectrum News. However, only 24 spots are available, and the nearest mass-market equivalent to BYD's charging stations takes around three times longer. These developments in fast-charging technology are hugely significant in encouraging more consumers to adopt electric vehicles. According to PBS, a poll found that half of Americans are reluctant to switch to an EV due to concerns about range. Although the U.S. has over 200,000 charging stations, coverage is patchy in some areas. Research shows that range anxiety is largely overstated, but ultra-fast charging stations will go a long way toward alleviating that concern. EVs still have some manufacturing issues, but they're a significantly better option for the environment than gas-powered cars. China leads the way in EV adoption, and BYD surpassed Tesla in annual sales in 2024. However, a 100% tariff imposed by the Biden administration last year has effectively shut BYD out of the U.S. market. This means offerings such as the $11,500 Seagull won't be available to American consumers. Still, the impact of China's massive market transitioning more toward fully electric vehicles is a significant boost for the country's long-term pollution reduction goals. As battery technology improves, range increases, and fast charging becomes more accessible, the future of electric vehicles is exciting.
