Power this elegant Bluetooth speaker with a candle (Wired UK)



If you, like Gianluca Gamba, have ever found yourself in the
nightmarish position of not having a wireless Bluetooth speaker
elegant enough for your Italian terrace dinner parties, fear not:
the Pelty is here.

Named after its power source, the Peltier effect, this speaker
uses the heat of a candle placed inside its ceramic and glass
surround to charge the thermoelectric generator — the Peltier
cooler. This generator is incredibly inefficient (the reason this
is possibly the first time you’ve heard of it) as it relies on the
creation of an electric current through a vast difference in heat
between two metals. But after a few seconds to warm up, there is
enough power for a speaker, which can then be connected to any
smartphone or tablet, bringing music and mood to anywhere you


Pelty – Play your firePelty

The Pelty has been brought to Indiegogo by three Italians working out of Milan.
The inventor, Gianluca Gamba, chose ceramic and glass not only for
their elegance, but because both have excellent thermal insulation
and acoustic properties. These help give the 3″ full-range speaker
an impressive frequency response, and loudness “to rival any other
Bluetooth speakers” at 90-95dB — loud enough to cause hearing
damage after six hours of exposure. Luckily, the candles usually
burn out after five.

You can back the project, which is a quarter of the
way to its $100,000 goal, for between $5 and $4,500 (£3 and £2,600)
with the lowest tier to receive the speaker coming in at $229
(£133). That may seem a mite expensive, however each speaker is
hand-made from Italian ceramic. That tier also only nets you a
black or white speaker-cum-candelabra, so if your terrace party has
a more vibrant colour scheme, you’ll need to up that pledge to $265
(£155) for one of the 6 other coloured variants.

For Gamba, the Pelty represents more than just an alternative to
trailing wires and mountains of rechargeable batteries: “The fire
in a brazier or the flame of a candle has always warmed the body
and soul of people, making them think, discuss, pray, laugh and

“This is the revolutionary aspect of Pelty: it combines these
two elements, the magic of the flame and the poetry of music, since
the latter is generated by the energy of the first.”
