I knew flames conducted electricity, but not they rectified it!

I'm not very familiar with the physics, but I suspect the effect is similar to a vacuum diode.

You can apparently even insert a grid and make a triode, interesting stuff. There are some vids on YouTube from a few different people if you look around.

Some good reading here. http://www.sparkbangbuzz.com/flame-amp/flameamp.htm

Yeah. A vacuum diode makes a cloud of electrons. A flame makes a cloud of ions. They are all charged particles, which will only drift in a particular direction in an electric field. As someone else said, you can use a grid to make a triode from a flame. You can also put plates around the flame and wiggle the ions with an audio signal, making a loudspeaker.

In the end it's just polarized dark fluid. :popcorn:
