A New Age of Materials Is Dawning, for Everything From Smartphones to Missiles

“Shifting substantial portions of what we make and use from steel and plastic to composites—which are amalgamations of a variety of fibers, embedded in a variety of plastics—could bring new kinds of transportation, more terrifying weapons of war, and lighter and more durable smartphones, wearables and other consumer electronics.

All of that is possible because composites, while they have their challenges, are often able to perform just as well as high-strength metal parts, but with a fraction of the weight. Composites are the reason modern jetliners are so fuel-efficient, and the entire wind-power industry would be impossible without enormous turbine blades made from composites.” (The Wall Street Journal)

Russian group adapts hoverboards into four-wheeled combat robots for use in Ukraine conflict. A Russian team is repurposing hoverboards to create makeshift four-wheeled robots for military applications in the ongoing Russia-Ukraine war. These improvised machines are designed for various combat roles, including kamikaze-style attacks, supply transportation, and smoke screen deployment. This development is part of a broader trend in the conflict, where both sides are increasingly utilizing improvised unmanned vehicles across different domains. While aerial drones and uncrewed maritime vessels have been widely reported, these hoverboard-based robots represent a new frontier in improvised ground-based autonomous systems. (via NewsScientist)
