Meyer type WFC - from design and fabrication to test and development.

Not yet been able to get another ali tube with which to test a full ali only cell.

But I am now wondering if the fact that my ss/ali test cell would not hold a charge is due to the ali being a very good conducter whereas ss is not.  Ali is at least 20 times better at conducting than ss, so it would have more free electrons.  Could it be that a lack of free electrons in my full ss test cell is what causes the voltage to remain?

I.e., I have ions on the plates from the water but not enough free electrons within the plates to react with once the power is turned off!

More food for thought.

You might want to check my last post http://www.overunity.com/index.php/topic,3742.new.html#new when using aluminum tubes. Aluminum will be sacrificed if there is any other metal in your process.

Hi,

w.r.t. using water as dielectric medium

Remember that water molecule is a dipole. This means that water molecules between charged plates will allign themselves with layers of dipoles between the plates, forming themselves small capacitors.

So in effect you will have a series of water "molecule layer" capacitors between the electrodes.

This is partly I think why it will take some time to drain the capacitor when shorting the "outer" electrodes....

Further to our discusions on other threads, I thought it more appropriate to continue this experiment here.

As I write I have my large test cell sitting in tap water with an added 1/2 teaspoon of calcium hydroxide (approx 1/2 teaspoon per 2 litre of tap water)

This calcium hydroxide is otherwise known as 'slaked lime' or 'hydrated lime', and is readily available from local builders merchants.  Note: It is an alkaline and an irritant so some care is needed when using it.

I only wanted a cupful of the stuff, but it was not available in any smaller amount than 25Kg bags. Anyhow, as it only cost ?8.50 for the 25Kg bag this was not a problem.

I've mixed in the calcuim hydroxide which immediately makes the water look milky.  Current through my test cell also immediately went up, so some of it obviously ionises.

Time will tell, but I'm not yet convinced doing it this way will work as the chemistry might be wrong. What I mean is that simply adding the calcium hydroxide to the water may not create the right reaction to cause it to deposit on my electrodes, as the stuff normally deposited on my electrodes is a product of a reaction, probably with calcium carbonate.  What I think that I really want to do is increase the amount of calcium carbonate in the water.  Perhaps some limestone and a pestle and mortar are the way to go...  But hey, I'm getting ahead of myself, my test cell has only been operating in the solution for 2 hours!

Ok, just a quick update.

After 5 hours at around 8 volts and .26 amp, my test cell does not appear to be showing any signs of getting the required coating after being immersed in the calcium hydroxide solution. Took it out and let it dry, but it actually looks cleaner than it did before I started, suggesting as I suspected, that this is not the way to proceed.

Anyone want to buy 25kgs of hydrated lime? (minus 1/2 teaspoon, that is)

Tomorrow I'm going to try again, this time by grinding up some blackboard chalk to see if things improve.

I really think it's possible to speed up the conditioning process, it's just a matter of getting the chemistry right.
