Screams were heard from within a wall at a Georgia county jail in January 2024, triggering security concerns and confusion by prison guards. Clayton County Sheriff Levon Allen said the man attempted his escape through the HVAC system of the facility. “This is just unbelievable," Allen said. "That young man did something that nobody has done in 24 years.” Now, the sheriff is putting new security measures in place in hopes of preventing this from happening again. Read more

The Korea Energy Research Institute has developed, for the first time in the country, a refrigeration technology that uses air as a refrigerant instead of freon gas, hydrofluorocarbons and other refrigerants that cause global warming. Researchers have successfully developed an ultra-high-speed integrated compression and expansion system using advanced design technology. The system is capable of cooling down to -100°C (-148°F), so it is expected to have wide applications in semiconductor processes, biotechnology, pharmaceutical storage and more. Read more

The top-hatted “drinking bird,” once a fixture in science classrooms for demonstrating the basics of thermodynamics, is making a surprising comeback as the inspiration for a new clean-energy generator that could one day power your watch and phone. Scientists in Hong Kong and China have used the famous toy to develop an engine capable of using the power of water evaporation to generate electricity, according to a study published on March 14. The new method works by converting the energy produced by the bird’s characteristic back-and-forth movement into electrical power. Read more

Several parts of The United States could be underwater by the year 2050, according to a map produced by Climate Central. The map shows what could happen if the sea levels, driven by climate change, continue to rise at rates of 2 mm and 4 mm. Read more

In the suburbs of northeast Paris is a giant terra-cotta-colored warehouse with a labyrinth of windowless corridors inside. This past summer, a deafening whir emanated from behind rows and rows of anonymous gray doors and under white striplights, disposable earbuds were available to protect passersby from the noise. These were the uncanny innards of one of France’s newest data centers, completed earlier this year, which was being used to heat the new Olympic Aquatics Center—visible from the data center’s roof.

Heating and lighting buildings requires a vast amount of energy: 18% of all global energy consumption, according to the International Energy Agency. Many buildings’ HVAC systems are outdated and slow to respond to weather changes, which can lead to severe energy waste. Some scientists and technologists are hoping that AI can solve that problem, despite its energy-intensive nature. However, experts argue that AI can also be part of the solution by making large buildings more energy-efficient. And early efforts to modernize HVAC systems with AI have shown encouraging results.
