Lol! I have found a recipe for fake moon dust.It was put together at Cornell university  pre-1969 moon landings.When the real moon dust and this fake moon dust was put side by side they were found to be almost indistinguishable in appearence and electrical and thermal properties.I don't what the electrical properties (or thermal) of moon dust is.The fake moon dust is composed of portland cement,charcoal,and hairspray.I thought this might be of interest here.My source is" Broco's Brain" by Carl Sagan cc.1974 page 233.

Sorry about posting the same message three times.I had a problem with this computer.I wanted to say that I do not know what the electrical and thermal properties of moon dust are.And was trying to correct my post when the computer started freezing up on me.triffid

G'day all

@triffid:  Funny you should mention Portland cement. One of the cells I made today contained 40% white buiders cement. This is similar to portland cement but much more refined like plaster of paris. I'm getting very good voltages from these.  0.757V with a surge current of 1.5mA.

@all: It appears that the electrostatically polarized cells get stronger after they have been shorted multiple times. That is with the formulas I use anyway.
The PP+SiC cell is putting out a steady 60uA or so across an AVO8 meter and has been doing this all day and all night. This is unlike the other cells who's current dwindles down to almost nothing after a few minutes.
However, the curing of any type of cement is a chemical reaction and therefore these cells are still galvanic. I will let you know how they stand at the end of the week.

Ok, move along please, nothing more to see here

MAP update:
Made a large MAP cell 12cm x 14cm. Left it shorted out for a few days.
I still get  over 600 mV.  A 10k resistor stays at a steady 60uA. which is the correct current at 0.6V.
A 1k resistor runs a little short at 400uA.  It should be 600uA.
So the cell seems to have a max. current rating of 400uA.
My MAP cell is made of a stainless steel pan with map in it and a piece of Aluminum foil on top.
The SS pan is the positive.   I heated it on the stove till the MAP melted and then placed the foil on top.
I zapped it with about 10kV from a flyback transformer circuit I built years ago.

For newbe's info "MAP" stands for "monoammonium phosphate". It is a piezoelectric material.
It is a common fertilizer sold at the Co-op for about $850 a ton.  I purchased a 100 pounds of it.
I place the MAP in 2 layers of coffee filters and tie it off. 
Then I put that into a pot of distilled water and boil it till the water is well saturated with MAP.
I poured the liquid into a SS pan. And evaporated it with a convection oven so a thin coating of MAP crystals where left.
