Toroidal vortex gun Make a toroidal vortex 'gun' that shoots doughnut-shaped vortices you have to see to believe. Video: Sleek Geeks Toroidal Vortex (Science Online Video) ...

These strangely-shaped twisted-loop propellers look like a revolutionary (sorry) advance for the aviation and marine sectors. Radically quieter than traditional propellers in both air and water ...

Despite being integral to aviation for more than a century, propellers have changed remarkably little since the Wright Brothers. A team at MIT’s Lincoln Lab has developed a new propeller shap… ...

Toroidal vortices, common in fluid dynamics, are newly explored in electromagnetism as two distinct forms: vector toroidal pulses and scalar phase vortices. This work proposes hybrid ...

Toroidal electromagnetic pulses can be generated using a device known as a horn microwave antenna. This electromagnetic “vortex cannon” produces skyrmion topological structures that might be employed ...

Toroidal inductors are often used in passive filter and equalizer circuits in the 1- to 100-MHz range. For appreciable relative permeabilities and moderate circuit selectivities ...

The obvious solution was to adapt the toroidal shape for a PC fan. He was familiar with the idea from similar screws on boats that are commercially available. You can see his tests in the video below.

The reason toroidal propellers may be quieter is because of their complex shape – it minimises the strength of the vortex (a spiralling movement of air, water, or another fluid) that naturally ...
