As industries across the board strive for greater efficiency and cost savings, a new technology has emerged as a potential solution: the toroidal propeller. This innovative propeller design, inspired ...

Dipole toroidal modes are a unique set of excitations that are predicted to occur in various physical systems, ranging from atomic nuclei to metamaterials. What characterizes these excitations, or ...

Imagine two toroidal permanent magnets arranged such that one is floating above the other for year after year. Where is the energy that powers this effect coming from? A couple of months ago, I penned ...

The basic configuration of traditional propellers has not fundamentally changed since the first powered flight by the Wright brothers in 1903. However, as engineers learn more about aerodynamics and ...
