Swiss startup Sirius Aviation AG has unveiled the pioneering Sirius Jet, the world's first hydrogen-powered vertical takeoff and landing (VTOL) aircraft for sustainable passenger transport. Developed in collaboration with leading aviation partners BMW Group's DesignWorks, Sauber Group, Alfleth Engineering, and ALD Group, the Sirius Jet claims to transform...
Space elevators have long captured the imagination of scientists and science fiction writers alike for their potential to revolutionize space travel. Rather than using expensive, single-use rockets to escape Earth's gravity, space elevators would transport payloads and even human passengers using cables anchored to the ground and extending...
UCLA engineers have unveiled a novel solid-state thermal transistor capable of rapidly switching heat flows on and off using an electric field—a long-sought innovation that could usher in a new era of advanced heat management technologies. The research team's room-temperature thermal transistor demonstrated record-high speeds, switching cycles, and...
