Hello, I'm new to this forum and hope that I'm posting in the correct sub-forum. My apologies if not. I was wondering if anyone has ever heard of anyone making a "perpetual" clock powered by batteries made with potassium chloride? In the past I found a website from someone who made and experimented with this type of clock. They had a working model of it. The clock wasn't really perpetual, but apparently was expected to run for a lifetime (or close to it). If I remember correctly the batteries were made in cardboard tubes and arranged around the clock. I also think that there might have been a glass dome covering the clock. I can't remember what the clock mechanism consisted of, but since I planned on building one, I would assume that it was just a regular purchased clock mechanism. I'm sure that the chemical was potassium chloride because that's what the "no-salt" seasoning is made from and is readily available. We have it in our cupboard right now. Because of this I was thinking that it would be a good project to make. This was a current project made with modern materials. I was sure that I had saved the link and sent it myself in an email but I can't find it anywhere. I came up empty searching the internet. I can't even seem to find any mention of a Potassium chloride battery like the one that I'm almost positive that I remember correctly. What I remember was a dry (or slightly moistened) powder that was pressed into a cardboard tube. A current internet search finds batteries that seem completely different and are made with a liquid in a jar. If anyone has any knowledge or information that they could share I would greatly appreciate it. It kills me that I can't find the original web-page. Thank you in advance. Regards, Tim
