The fan has a small gnome creature permanently jailed for his crimes between the bottom foot and top fan. When you heat the bottom he bounces around Mario 64 style and rotates a small crank attached via string. This motion generates enough energy to spin the fan at like 3 rpm. The gnome cannot be released under any circumstances.

It detects when you are in heat, and turns on.

the heat actually vibrates the blades of the fans at a special frequency that allows it to communicate with the undead.

using a special set of mircoscopic engravings on the back of every odd numbered blade, it communicates with the vengeful spirits and asks for a man named 'josh'.

once the fan hits 100°c, and josh is successfully conjured, he utilizes his insanely strong arms to push the fan in a counter-clockwise direction.

upon the cooling of the fan, josh relieved of his duties, and sent to the break room. another spirit is premoted to a 'josh' to take his place.

Ghost blowing on it like a pinwheel.

Straight up magic

It gets hot, then it blows you- what else is there to know?

Why is the gauge missing rpm?

And when will this tech evolve for human body heat?
(I want to fly using by buttplug!)

Wind turbine for Jesus farts.

It's steam, like almost all power obviously.

There's a little guy in the hub and as it gets hotter he begins running trying to escape which creates rotational energy to spin the blade

The 5G sends theta control waves to humanoid brains and the closest human to the fan reflects some of those control waves onto the collecting fins on the body of the fan, thereby resonating and making the fan blades spin.

Obviously.

There are little gnomes inside and when it gets hot they start hopping. That hopping powers the fan.

It aligns itself with the magnetic field of metal of the stove and starts a transduction of capicitive resonation that interferes with the polaritive vibrations of the planetary magnetic field.

This in turn creates a localized pulse of geomagnetic interference that the fan blades are sensitive to, and their shape works to create a single direction rotation that both pushes air and traps the interference and creates a perpetual motion at the same time.

Brilliant engineering, honestly.

When it's hot enough, the blades start melting. As metal slowly drops, they get lighter on the inner edge (thinner part, melts faster), and start rotating because they're not balanced anymore.

Quite simply, as it says, when things get heated, such as during a fight with your spouse, the fan will start trying to escape which causes it to spin.

This also works if you start yelling at it yourself, although you need to be genuine. It can detect if you're lying, so get angry!

It doesn't work. It's an optical illusion, but is so compelling that yiu hallucinate feeling the air move.

This was first used on gas stoves, which is where the term gaslighting came from.

You rig it to a boiling pot of water and the fan creates electricity from the boiling water to power the fan

There's obviously a group of very small people trapped inside a hamster wheel style contraption. As the fan structure heats up, the floor of the wheel grows uncomfortably hot, and forces the little people to continuously run to avoid getting burned (continually cycling the cooler top of the wheel down to the bottom). This in turn turns the fan blades.

I am honestly appalled that you would buy such a thing; it's cruel.

Thoughts & Prayers ^TM^

This object is stationary. It's base is full of LSD, Magic Mushroom and a choice, proprietary cocktail.

Eat the drugs and you spin, while the fan just watches you and silently approves.

When air is warm, it rises. As the air attaches to the blades, the air is tricked into accepting a new definition of "up" which rotates with the blades, endlessly propelling them.

As that air cools, warmer air is drawn in and entrapped, continuing the cycle.

Love

Heat power like the box says, duh!

Witchcraft! Sorcery and devil's work!

Its a worp engine

It converts the vibrations from me shagging your mom in the kitchen.

Charle's and Boyle's gas laws. PV = nRT. As the temperature rises it creates a sudden increase in the volume and pressure of the immediate air. The increase pressure and volume in a closed room forces the fan blades to turn.

Little men with packets, inside these packets, they carry an electron. When it starts getting hot on the one side, they all run away, bringing in cold men with packets, and the cold 9nes can't stand being so cold, so they're constantly standing in line ot be by the fire again.

The stove is hot so the fan is just trying to cool itself down. Duh.

It's a fan powered by the thrusting of people in heat who are fucking because they're stuck inside on a cold winter night. It thus harnesses the unlimited power of horney people to keep homes warm and well circulated.

Tiny gnomes.

Spite

The hot air from the stovetop move the blades like a windmill obviously

The picture is misleading. It's actually a fan of stoves who eats heat and prefers the heat created by stoves, hence being a huge fan of a stoves.
