At the very crux of engineering is the desire to problem-solve, optimize, and squeeze out every bit of efficiency possible from the system being built. Aircraft design and aeronautical engineering ...

Sharrow's extraordinary looped propellers were already some 30% more efficient than traditional designs – and now the company has put two of them together into a coaxial, contra-rotating prop that ...

We interviewed the core team at Norway's World Wide Wind to learn more about its floating, tilting, contra-rotating, double turbine design, which it says can unlock unprecedented scale, power and ...

World Wide Wind, a Norway-based company, is now developing a new type of floating Vertical-Axis Wind Turbine (VAWT), as reported by Interesting Engineering. Engineers believe that the VAWT can make a ...

Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ...

Integrating sensors into rotational mechanisms could make it possible for engineers to build smart hinges that know when a door has been opened, or gears inside a motor that tell a mechanic how fast ...
