Well done!

Neat I will try it next time I make that trip to fraight

[smellanalan]

Very very cool! I actually understand this one haha, and I will show some friends, thaks pyrolytic!

[pyrolytic]

@smellanalan Thanks. Actually, one could substitute plain old liquid bleach in the cloth instead of the salt water solution (electrolyte) and have even a better battery

cell....if.....one could stand the strong noxious bleach smell....or move it outside of the

house to dissipate the smell.

@pyrolytic See you keep filling my brain with more! I look forward to more experiments!

I guess it is a little impracticle, but still neat!

[pyrolytic]

@COBladesmith80 Yes; it is definitely impractical from the economics standpoint;

everything involved is much more expensive than just buying or having a common (and much more powerful) battery. It's more directly in the line of a temporary, student, "science fair" type thing.

Cool! How long will it last?

[pyrolytic]

@jmwnycprr As long as the saturated salt/water cloth is kept moist (without drying out); and/or when the magnesium block eventually oxidizes completely (probably measured in ~ a month or more). As shown this is a short term (?~hours) battery. A added adjacent jar filled with saturated salt water and extended cloth capillary action can be added to extend the battery for extended battery operation. Of course; it's cheaper to just use a commercial battery. ;>)

Cool!!
