of Bernoulli's principle a low-pressure region is created at the inlet of the hoop. This pressure difference induces more air from behind to the front of the bladeless fan. The air coming out of the bladeless fan is as a result of sucked air, induced air, and entrained air which is more than only sucked air, thus the air is multiplied.
The fan is equipped with a thermoelectric module, also known as a peltier device. This module consists of two different types of conductive materials placed between a hot and cold surface. The base of the fan (the hot side) absorbs heat from the stove, while the top of the fan (the cold side) is exposed to cooler air in the room.
