Re: Saltwater ballast

I did that some years ago, but wouldn't do it again for several reasons:
1st: The combination of saltwater and electricity is quite dangerous as you
can imagine, one must have a very good container with some isolated handles
to move the electrodes and that prevents the saltwater from spilling around
2nd: you can't use a sealed container because of the gases that develop,
that means there will allways be a chance of spilling some water and by that
getting in contact with the AC line
3rd: the gases are mainly oxigen and hydrogen in the best ( or worst )
mixing ratio ( 1:2 ) known as detonating gas, thats very likely to explode
if any arcing occours.
4th: from the salt in the water ( NACL ) you will get chlorine which is not
only noxious but will cause metal parts to corrode very fast.
5th: for TC use: this is a pure resitive ballast, which means you will waste
a lot of power and loose secondary voltage, it might only work well in a
combination with some kind of inductive ballasting.....
I have to admit, this saltwater thing really seemed to be undestroyable, but
for the above reasons I wouldn't recommend it.
