Tealight fire tornado candleholder

FIRE!! Or disperse the scent of a scented candle faster, if you're not a pyromaniac.
  [vote for,

I watched a great many videos by [Big Clive] the other day. (I highly recommend his channel to halfbakers: [link]. I also recommend watching YouTube videos of that sort at 1.5× or 2× speed, the option for which is in the gear menu at the bottom right of the player.)

A few of them were on scented candles, wax melters, and the like. One video was on melting wax with electric heat to help it burn: [link]. It mentions a particular scented candle product by Glade, which seems to try to conduct heat from the flame to the wax with metal legs, though ineffectively. Comments on the video also suggested adding copper wire to a normal candle to conduct heat down from the flame to melt the wax at the edge of the candle to help it get burned, because sometimes it remains unmelted.

All of this also reminded me of one of [wbeaty]'s ideas, that of putting multiple paper wicks into an existing candle to produce a several-inch-tall roaring flame: [link]. (I have done this and it works.)

Here is my idea: A candleholder for a tealight, votive, or other wide candle, particularly a scented candle, that consists of a base where the candle sits, with a vertical tube of borosilicate glass or other heatproof and preferably transparent material mounted above it, with a gap between the candle's upper edge and the tube's bottom end for air intake, with a durable heat- conducting wick assembly, which contacts the top of the candle between its center (where its own wick is) and its edge and extends upward and toward the center, mounted inside the bottom of the tube in such a way that it can slide vertically.

The tube may, preferably, have aerodynamic features to promote swirling of the airflow as it ascends. The tube may also be mounted to the base in such a way that it can slide up and down to maintain its position relative to the top of the candle as the candle is consumed, if the candle is a caseless type (i.e. not a tealight). The wick assembly may be in the shape of a cylindrical helix, a conical helix, a pyramid, etc., and may be made of fireproof fabric wrapped around metal, metal with micro-grooves or other capillaries to draw the wax up, or some other material or composite that fulfills the purpose. The base may have anti-tip-over features such as a wide base area or wide legs. The tube or other parts may be equipped with a safety cage or other features to prevent damage or spread of fire if the candleholder is impacted or knocked over. The top of the tube may also be equipped with a disperser, which directs the flue gas outward both to disperse scent more effectively and to avoid inflicting thermal insult to any object above the candleholder. The disperser may send the scented air farther by forming it into vortices, as commercially available vortex air circulator fans do. The disperser may also function as a soot filter or adsorber, or electrostatic precipitator, similar to [tchaikovsky]'s Soot Shield idea: [link]. If it is an electrostatic precipitator, it may be powered by the heat of the candle via a thermoelectric generator, as commercially available heat-powered fireplace fans are.

Operation is as follows: Raise the wick assembly up out of the way of the candle. Insert the candle and seat it on the base. Lower the wick assembly to rest on top of the candle. Light the candle's own wick (which is already impregnated with wax). Wait for it to melt some wax, which will be wicked up by the wick assembly. This will happen quickly, because the wick assembly collects heat from the flame and conducts it down to the wax. Soon a tall, roaring, swirling flame will fill the tube. As the candle is consumed and gets shorter, the wick assembly (and the tube, if so equipped and/or configured) will slide down to follow it.

The purpose of this is to facilitate the rapid dispersal of scent from a scented candle, the enjoyment of fire, or both.
