Pelty bluetooth speaker powered by a candle

The inventor Gianluca Gamba has a new way to make your candlelight dinner more elegant: Pelty wireless speakers are assembled into tower candle holders, and the speaker is located beneath a tea wax, where the heat output provides Bluetooth speaker power.

The idea behind the candle is very simple - the inventor discovers that the traditional portable Bluetooth speaker becomes inappropriate in his elegant dinner arrangement, so he sets about making his own choice. As a result, a ceramic base unit has a glass envelope and a thermoelectric conversion element. The candle/speaker combo took Gamba about 18 months to create. With the small tea wax feature above the picture, the integrated 3-inch driver will run for up to 5 hours. The "charging" device is very simple, just replace the candle.
It promises that almost all of the candle heat will be used to power the device, and the audio quality and loudness must be high. A month or so later, the device has received more than 15% of its funding target through Indiegogo.
