The electricity aligns all the molecules in a very ordered pattern which is what causes the geometric seam pattern when it starts to melt. As for why it prevents bubbles, I'm not entirely sure, but my guess is that it excites the molecules enough to release any air dissolved in the water.

I think it causes slow transport of the crystaline nucleation sites... not much different from using microwaves? I do know that + vs - ions can cause directional freezing with impurities pushed to one side. Also, anything that slows freezing tends to make clearer ice because air bubbles have longer to escape.

Interestingly enough, water is actually a terrible conductor of electricity. Electrical current jumps through water piggybacking on the various mineral impurities in the water, not the water itself. For that reason, using distilled water might actually work against you if you try to make the water have a negative charge with electricity. The current might not be able to go through the water properly if there's a lack of minerals.

That's correct. Really pure water generally has high resistance. However, electrolysis of salted water can separate water into Hydrogen and Oxygen even using something as wimpy as a 9V battery .

Where's an electrical engineer when I need one!? :/

Well, I'm a Professor in Electrical and Computer Engineering... but that doesn't help me much with this (I'm really a computer engineer). Maybe somebody involved in battery chemistry?
