I love it. I did this when I was younger, I tried aluminum steel and copper, the metals that were handy

I have been building batteries in my shop for just a little while, progressing from one experiment to another looking for the ideal non toxic homemade battery. Interesting you only have the two videos on the subject. Your tests are clear, concise and well presented, unlike some I have seen. Keep up the great work. I wonder, what do you think about wrapped cell using copper and aluminum screen material with an insulated paper or plastic separator? Something like how a capacitor is made.

dont all batteries need dis similar metals for anode and cathode tho?

If it can be dry then somehow do a dry mag battery

If you only use sand with no electrolyte do you still get .5v ?

Thank you for your great experiment! Very helpful 👍 Erich from New Zealand

What containers do you use for the batteries? They look like film canisters. I am looking for easily built batteries that rival the Edison battery - long life, renewable, rechargeable, moveable without spillage, and cheaper to build than lead acid technology. "Kitchen chemistry" batteries. Where do you source the copper and aluminum? How thick are each plate and what concentration of electrolyte are most efficient? I am looking to use prescription bottles as containers and a wooden box to hold the cells together. What temperature range will the cells tolerate for full output. Or, should I imitate the Edison cell technology for efficiency? Have you tested your cells for current output? How do you recharge the cells (constant voltage and current)? I will bookmark this video for comments that I can return to at a later date and view.

This little stunt got me exiled to the out of doors. Made the kitchen smell of chlorine and started eating the spoons. Stainless doesn’t like chlorine. Now I know. On the bright side it generated about a volt before I dumped it. The Epsom one settled down to about a volt. Still cycling charge and discharge.

I just did a quick Google on stainless steel, found quite a long explanatory article so I am pasting a short extract - Stainless steels are iron-based alloys primarily known for their generally excellent corrosion resistance, which is largely due to the steel's chromium concentration. There are several different types of stainless steels. The two main types are austenitic and ferritic, each of which exhibits a different atomic arrangement. Due to this difference, ferritic stainless steels are generally magnetic while austenitic stainless steels usually are not. A ferritic stainless steel owes its magnetism to two factors: its high concentration of iron and its fundamental structure. -- I will add a link to the article in my video description for reference 😁 👍

That is a great comparison 👍👍👍

Liking it already and only one minute in 😍👍 great idea using the sand 👍
