The smallest motor in the world

A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor ...

Intelligently recovering and recycling balsa wood

There are 30,000 wind turbines in operation in Germany, many of which are starting to age. In 2019, 2000 rotor blades had to be discarded; in 2024, this figure will shoot up to 15,000. But where to put these up to 90-meter-long, ...

Ion wind technology breakthrough takes flight

A new spin on propulsion is taking flight in a SUNY Oswego lab, leading to electrical and computer engineering faculty member Adrian Ieta and the SUNY Research Foundation pursuing a patent on this promising technology.

To improve drones, researchers study flying insects

The unmanned aircraft known as drones, used by hobbyists, researchers and industry to take aerial images and perform other tasks, are growing ever more popular—and smaller. But that miniaturization, which has produced drones ...

Improved control of big power in little motors

Little motors power everything from small comforts, such as desk fans, to larger safety systems, like oven exhaust systems—but they could be more precise, according to a research team from Mitsubishi Electric Research Laboratories.

Toward urban air mobility: Air taxis with side-by-side rotors

In this high-resolution visualization of NASA's side-by-side, intermeshing rotor air taxi concept, researchers are working to understand complex rotor air flow interactions, simulated using high-fidelity computational fluid ...

Improving drone performance in headwinds

The prevalence of multi-rotor drones has increased dramatically in recent years, but in headwinds, they pitch upwards unpredictably. Engineers from Tohoku University, Japan, have shown that angling the rotor blades of a quad-rotor ...
