Suprock Technologies has created a thermoelectric generator that produces useful electricity from low heat sources. In this video, we demonstrate a tea candle running a high power LED to produce light many times the intensity of the candle. We call this the Candela Amplifier because it takes waste heat from the candle and turns it into useful luminous intensity! Imagine that in the 21st century, candles can be re-purposed to replace chemical batteries!

This is redundantly awesome.

Well, yea. Hook this up to the headlights in your car.

@Joshuab213 want me to scratch your head for you? cos I think i can just reach if i open the window!

this would be a clever spin on those old lanterns that uses a flame.

would also work well on a wood stove.
How well does it fair against the inevitable candle soot that builds up?

Wow. Nice job on this. =)

"Suprock Technologies has created a thermoelectric generator" you mean you took a Peltier chip, soldered an led and attached a CPU heatsink to it?
AMAZING I did this for my 6th grade science fair...

I'm hot happy with the thermal design of this. Convective cooling requires vertical fins.

This is a very cool project. I think the candle puts a lot more energy in the IR band than the LED. It does beg the basic questions:
1. Is there more energy in the heat produced in a candle flame than in the light it produces? (I suspect maybe yes...)
2. If the candle light were focused to the same radiation pattern as the Cree X-Lamp would the luminous energy be higher?
I would not want to speculate on the latter, but it would be an interesting bake-off.

@lumpyren
The claim is that the LED produces a higher intensity (W m^-2) than the candle.
"light many times the intensity of the candle"
This is probably true within the beam of the LED - indeed, one could drive a laser diode and have an intensity many orders of magnitude higher than that of the candle!
The original claim, I think, is legitimate.
