The most widely used method uses Neon Sign Transformers, 12 or 15 KV, and places
the silver electrodes just above the water's surface, so that the voltage pulls
the water up and around the elecrode.  This results in a crude voltage 
regulator,
since as the voltage decreases, less water will get pulled up around the
electrode, increasing the resistance, and vice versa.  This regulation is
necessary since the bulk conductivity of the water/CS starts off very high, and
drops by several orders of magnitude as ions are generated and diffuse into the
water.  If you just submerge the electodes, then there will be a wide range of
current from start to stop, generating a poor quality product.

The method I use, which I have applied for a patent on, submerges the electrodes
inside of pyrex or quartz tubes.  Only the tip of the electrode is exposed
outside the tube under water, and is adjusted to be about .1" long.  Then water
is cooled to just above freezing and pumped through the electrolysis cell at a
constant rate (about 3 gallons per hour per 100 mA).  The amount of electode
exposed is adjusted real time to maintain a voltage of between 9 and 11 KV at 
all
times.  The CS leaves the chamber at about 105 F.
