The lightweight paper frame holds certified solar filter material that reduces the sun's intense radiation to safer viewing levels. The European Space Agency warns that ordinary sunglasses are not suitable for looking directly at the sun, and recommends proper eclipse glasses instead. What makes these glasses fascinating is how advanced protection can be built into such a basic design. The frame is lightweight and inexpensive, while the most important technology is hidden inside the specialized filter. During a total solar eclipse, the glasses can briefly be removed only when the sun is completely covered, and they must be worn again as soon as sunlight returns. This simple combination of practical design and specialized filtering makes eclipse glasses an essential tool for experiencing one of nature's most spectacular events safely. Anduril Thunder introduces a different approach to military aviation by combining rotorcraft design with autonomous technology and onboard computing. Developed as an uncrewed attack rotorcraft, Thunder is intended for missions close to the ground where traditional crewed aircraft can face significant challenges. Instead of simply adding automation to an existing helicopter, the aircraft is being designed around autonomy from the beginning. Its concept connects autonomous flight, advanced sensing, software-defined systems, and local computing into a single platform. Anduril's Lattice technology emphasizes processing information close to the point of operation, helping autonomous systems remain functional when communication links become limited or unreliable. This can reduce dependence on distant control infrastructure while supporting faster responses to changing conditions. Thunder reflects a broader shift in aerospace engineering, where software and autonomy are becoming fundamental components of aircraft design. The result is an unusual military aircraft concept built around uncrewed operation, onboard intelligence, and autonomous capabilities from the ground up.

Pulling carbon dioxide out of ordinary air sounds simple in theory, but doing it at industrial scale requires enormous amounts of engineering. Climeworks Mammoth in Iceland is designed for exactly this purpose, using direct air capture technology to remove CO2 from the atmosphere. The facility features 72 modular collector containers and has a designed capture capacity of up to 36,000 tons of CO2 annually. Air passes through specialized collectors where solid materials capture the carbon dioxide. The captured gas is then processed and sent to CarbFix, where it is dissolved in water and injected into underground basalt formations. Over time, the CO2 reacts with the rock and becomes permanently mineralized. Mammoth operates using Iceland's low-carbon energy resources, including geothermal power. The facility is also an important real-world test of modular carbon removal technology, providing operational experience that could help future projects scale towards significantly larger facilities capable of removing much greater amounts of atmospheric carbon dioxide.
