Juice

In my quest for juice (electric kind), I tried a few things.I took a HDD apart and instead of removing the magnets, I left them intheir steel bracket assembly. I took the head assembly out and brokeoff the heads, leaving the coil. I soldered some leads to the flexprinted circuit, and ran them several inches to a red LED. What's coolis I can wiggle the coil in the magnet and it lights the LED brightly.I get pulses of light when the head is moved in one direction. Man, I'mmaking juice! :o)Not very practical, tho. Then I got this idea from reading a sciencefair project for grade school; I decided I would try to make juice witha homemede battery. I cut off the bottom of a plastic bottle and Ifilled it with water and white vinegar in 2:1 mix. I put a piece ofaluminum and a piece of copper into this, with leads attached to a DMM.I can get about a half volt open circuit, and with the meter on currentrange, it will give about 4 or 5mA of currnet thru the DMM. I'mguessing that both voltage and current will be somewhat lower when aload is put on it. I'm making more juice! But I'll have to put 3 or 4of these cells in series to get enough power to do something useful.My q is, what should I do to improve the cell's output? Should I changefrom copper and aluminum to copper and zinc? Or some other metal? Ifso, where do I get a nice piece of zinc? The size of the copper andaluminum pieces is a few square inches. I guess using larger pieceswill give more current. But I'll have to put them in a bucket! Whatkind of electrolyte should I use? Is there something better thanvinegar? I had thought about battery acid, but it's so nasty and eatsholes in everything. I have CuSO4 tree root killer crystals. I coulduse that I suppose. But is there something other than lemon juice (usedin these science fair projects) that's a better choice? Thanks, Iguess. I may end up making a real mess!--@@F@r@o@m@@O@r@a@n@g@e@@C@o@u@n@t@y@,@@C@a@l@,@@w@h@e@r@e@@###Got a Question about...

I read in alt.binaries.schematics.electronic that Tim Williams wrote (in ) about '~~Juice~~', on Mon, 14 Mar 2005:

Since my equation shows K2O being formed, I don't see what you doubt. The 'gas' in this case is H2O. K2O doesn't 'burn' in air but it *might* attract more oxygen to form KO2.
