Gliders are the most efficient flying machines ever built—and the most advanced among them come from Germany. Aerospace engineers around the world know this well; time and again, they draw on ideas from glider technology when building their latest aircraft. Even the fast-moving air taxi industry is eager to benefit from the expertise of the gliding community.“Vertical takeoff” doesn’t just describe a flying machine lifting straight into the sky. It’s also a phrase for any career—or breakthrough—that takes off steeply ...

From leaf blowers and electric cars to massive grid storage systems—lithium-ion batteries are the undisputed stars of the battery world. But their environmental impact is coming under increasing scrutiny. As a result, researchers are racing to refine and even replace them.Last year, a battery came online in California’s Mojave Desert that is nothing short of colossal. The Edwards & Sanborn project consists of 120,000 battery modules, capable of storing roughly 3.3 gigawatt-hours of electricity. At its heart: lithium-ion cells. Currently, ...

Reinforced concrete components are typically bulky and heavy. That is starting to change: components reinforced with carbon fiber are enabling entirely new forms and unprecedented lightness. At the same time, the environmental footprint of these structures is improving.Balcony slabs are usually made from reinforced concrete. On average, a typical slab measures two by five meters and is 30 centimeters thick, tipping the scales at around 7.5 metric tons—about as much as a small delivery truck. The supporting framework needs to ...
