DENJIRO: For today’s experiment, I’ll teach you how you can easily make a charcoal battery at home. It’s actually quite powerful. Now, let me teach you how to make a charcoal battery.
NARRATOR: You need four materials: saltwater, Binchotan charcoal, parchment paper, and aluminum foil. First, wrap parchment paper around the Binchotan charcoal. Then, pour saltwater on it. Lastly, just wrap it with aluminum foil.
DENJIRO: It’s complete. I’m going to attach a motor to the Binchotan charcoal and aluminum foil. The motor is running. Let me explain how electricity is generated.
When aluminum foil melts in saltwater, electrons are produced. When air inside the Binchotan charcoal receives the electrons, a flow of electricity is created. Charcoal batteries are very easy to make, so try making one yourself and experimenting with it.
The charcoal used has to be Binchotan charcoal. When Binchotan charcoal is made, it is heated to over 1,000 degrees Celsius. Charcoal baked at a high temperature conducts electricity, and therefore can be used as a battery.
NARRATOR: Even if you use regular charcoal, it will conduct electricity if it is baked at a high temperature.
DENJIRO: Now, I’m going to heat this charcoal with a burner. Furthermore, I’ll heat it up even more with a blower. I’m going to attach a battery and lightbulb to the part that was heated.
BOY: The lightbulb turned on!
DENJIRO: The lightbulb is on. That’s because the charcoal is conducting electricity. By heating the charcoal, the molecular structure of carbon changed. That’s why it was able to conduct electricity like Binchotan charcoal.
Take a look at this. I’ve connected large charcoal batteries in a series. I’m going to try and put on a light display.
BOY: It’s beautiful!
NARRATOR: By using large Binchotan charcoal, there is more electricity flowing. Therefore, the lights can be turned on.
DENJIRO: I hope energy will bring you all happiness. Our magic word is "Happy Energy!"
