Might want to recheck your science books Water is not a conductor. Pure water has an extremely high resistance. It is the minerals and salts that ionize in a water solution that cause it to conduct.
Yup, agreed. Just didn't get how you got that water had to have salt specifically in it.
I have no idea how much mineral content is in snow though.
Apparently not very much, since most electric fences don't get sufficient open current from ground when there is snow. Mind you -- the ground itself is very dry in the winter, which is another issue. The less moisture in the ground, the less ground you get. [/quote]
"A" DC charger... How many joules ? How much wire? What type of terrain Have you ever actually tested the current in the wire with all this brush you mentioned ? DC chargers that use a deep cycle car battery sized battery can do the job but do you really wanna be hauling 70lb batteries back and forth to recharge them ?
I'd have to go check how many joules. It was a $150 charger from Princess Auto -- "the better one" LOL. Terrain is clay / rock / swamp / gravel with trees, underbrush, clear areas. Yes I have tested the current. It is equal charge for the full length. And, yes, I do use either a car battery, large marine battery or even a large truck battery. As for hauling it around -- during the summer, I change out the battery only once. No big deal. During the winter, I don't know how often I have to recharge. Can't remember, but it's not a big deal to put the battery on a sled and drag it up to the shop. Hopefully soon I will have my power back and then I run a trickle charger on the the battery when needed.
High tension cable will get your job done and deer and bears can't break it.
Agree again, but in some situations that is just too much work or impossible. Here it is just about impossible to get a post in the ground that will stay in position through the freeze-thaw cycles because of the clay. I've never seen ground heave like this stuff. The first spring we were here I was shocked. Literally 5 foot heaves! It's wild.
