Hydrogen Flame Detection Methods:
NASA rockets rely on liquid hydrogen and oxygen for fuel, maximizing tank volume for lift. But if the highly combustible hydrogen leaks, it can lead to a massive explosion.

NASA struggled with hydrogen leaks, grounding the Space Shuttle program for months during the "Summer of Hydrogen." Hydrogen's invisible flame in daylight posed a challenge.

Engineers used a low-tech solution during the Apollo missions—walking with a broom. When the broom touched burning hydrogen, it combusted, revealing dangerous areas.

Later, NASA employed sensors and ultraviolet cameras for leak detection, providing better accuracy. However, visual indicators were still lacking.

Collaborating with the Florida Solar Energy Center, NASA developed chemochromic tape that changes color in the presence of hydrogen, offering immediate leak detection.

Hydrogen leaks remain a concern, as seen in the aborted Artemis 1 mission. NASA must address the challenge of the most efficient fuel being the most dangerous to prevent future leaks.

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
