The toroidal design of the object allows for efficient flow of energy.
Toroidal → It is formed from "torus" (from Latin *torus*, meaning a rounded or circular shape) and the suffix "-oidal" (from Greek *eidos*, meaning form or shape). The word "toroidal" describes something that has the shape of a torus, which is a doughnut-like structure.
Imagine a doughnut shape, which is what 'torus' refers to, and remember that 'toroidal' means something that has that rounded form.
