Copper Zinc Tap Water Fuel Cell

Each cell used a 4 1/2” x 1/2” galvanized steel triple coated conduit; 4’ of 14g copper wire and bottled drinking water.

Nice,
I am glad you did this.
They are handsome too.
In the plant battery experiments I learned that I could increase the mA a surprising amount by adding a longer length of copper.
This means the sacrificial metal is kept to a minimum.
At 7 cents this is not a problem as you say. ( )

My hope is to use this as a power source to learn and build a good joule thief.  That thread is so huge, so much to learn.

Go to the joule thief 101 thread started by resonanceman.
If you copy/paste my several entries, you will get my suggestions for how to get going on a joule thief etc. (Of course, it is my take on it.)

Great stuff.
Thank you,

jeanna

I certainly understand how space and money constraints can impede participation in the many directions being explored here at overunity.  Never underestimate the value you give to a newbie like me when you exchange ideas, experience, and suggestions as you have.  Kudos to you!

@jeanna
Thank you for sharing your plant battery experience with me.  This information validates a statement made in reply #7 â€" “A small anode (zinc) and a large cathode (copper) will result in high current density in the zinc, hence a high rate of corrosion.”  More test cells need to be constructed and monitored.
I will definitely take you advice and start with the joule thief 101 thread.  Since you were one of the pioneers of this technology â€" I will gladly follow your “take” on this subject.
Thanks â€" Brad S

@all
Perhaps some of you need a good laugh today at the expense of a newbie.  I humbly offer myself to you.  I want to make certain that any results posted on these galvanic cells have been performed correctly.  Attached is what I think should be the correct measuring method with my multimeter.  Would a kind member please confirm or reject this?
Thanks â€" Brad S

You betcha, and thanks to you.  Let's all learn something while we're here.
