I was so impressed when I first saw the crystal cells being touted as INFINITY CELLS or FOREVER BATTERY that I just had to look a little deeper.
I found a site that showed how some of these crystal cells are made. The components were as follows:
Copper Pipe
Magnesium Rod
Magic Powder (Equal parts of Epsom Salt, Alum, Potassium Chloride and Borax).
I had all the parts with the exception of the magnesium rods so I used aluminum rods in place of the magnesium. It was suggested that aluminum would work but at a lower output voltage.
On April 2, 2015, I made my first crystal cell with the aluminum rod, copper pipe and the magic powder. I used a torch to lightly warm up the copper pipe so that the magic powder would dissolve and sort of melt into the space between the copper pipe and the aluminum rod in the center.
When this crystal cell #1 was cool enough to pick up with my hand, I put a meter on it and it read 0.536 volts. Over the next few days the voltage ranged from 0.619 volts to 0.633 volts.
On April 6, 2015, I made two more crystal cells using the same components and ingredients as crystal cell #1.
For #2 crystal cell, I used a different method of construction. I used a section of PVC pipe that just fit between the copper pipe and the aluminum rod. I put some magic powder and compacted it with the PVC pipe. To get it well compacted, I used a mallet to pound it in with lots of pressure.
For #3 crystal cell, I used the torch method to melt the magic powder into place.
In summery, the output voltage for the 3 crystal cells on April 6, 2015 were as follows.
Crystal cell #1 = 0.622
Crystal cell #2 = 0.522
Crystal cell #3 = 0.555
