I think you have the Edison account backwards.
This from memory - may be faulty memory of course :-) - He used DC
distribution and touted it's safety compared to AC. So much so that a number
of his linemen died from excessively believing his spiel.


>This sounds a little impossible as AC would alternately contract and
release your muscles forcing you to release it! This is one of the reasons
we have AC supplied to our home and not DC, among ather obvious reasons.

If you have ever found yourself attached to an AC source of significant
potential you may have found that letting go is difficult notwithstanding
the cyclical contraction and release of muscles. 50 Hz is rather fast and
reversals effectively occur at 100 Hz. Numerous people will tell you stories
about not being able to let go from an AC contact.

> Edison pushed for the use of AC by demonstrating on a horse. He'd fist hit
it with AC and watch it bolt. When caught he'd again shcok it with DC
killing it stone dead.
