I've only recently returned home from work and haven't had a great deal of time yet to explore metals further and many I do not have available but by filling one icecube 'cell' with mere tap water these are the results I've managed so far:
Silver/Aluminum: 0.63V
Graphite/Aluminum: 0.34V
Silver/Nickel: 0.33V
Graphite/Steel: 0.30V
Nickel/Aluminum: 0.22V
Silver/Copper: 0.15V
Nickle/Graphite: 0.12V
Silver/Graphite: 0.04V
Copper/Graphite: 0.00V
Gold/Graphite: 0.00V
Now I understand that metals are considered on a scale from least noble to most noble. My question is this: Have any of you tested Gold/Magnesium and would that be the highest potential since Magnesium is least noble and Gold is most noble? If that wouldn't give the highest potential do any of you know what would? Now I'm just experimenting on a basic level with water right now because it is a quick way to discover which metals work best together so I realize an optimal electrolyte would give more efficient results. Actually, now that I'm thinking about it, what are the best known electrolytes for efficiency in relation to some of the metals I've been testing this afternoon that will not eat the metals away too rapidly? I know I can figure it all out on my own eventually but any shortcuts are appreciated since time is often not my friend and I'm sure most of you can relate to that! Thanks for reading me.
