| All the electric motors, less the DC motors, would have to be changed 
out to ones which would run at the higher frequency. That would be one 
way to lower the unemployment rates..hi hi....... One would have to use 
120 Hz to make the RPM match up in the end I would think. If the speeds 
were increased, the torque drops so they would have to use the same 
speed motors that is currently being used. If the motors run at X2 the 
speed, the torque would be 1/2 what it supposed to be thus any hoists or 
cranes would only be able to lift 1/2 the load but X2 as quick. Same 
thing in any other machinery too. That would end up a very expensive 
change over =)

 Isn't the natural frequency for nervous system about 40 Hz? I 
remember talking to a guy who was investigating the use of 
electromagnets to help with healing, and if I remember correctly, he 
said it was at 40 Hz. I can't remember to be honest, does anyone know?
 
 
 
 
 Will, there is no 'natural' frequency for any mammalian nervous 
systems. There *are* several well-known rates devolving from varsious 
neurlogical processes, but the rate and frequency of action-potential 
propagation in the nervous system depends on the originating stimulus.
 
 If you grab the wrong end of a soldering iron, that particular group 
of impuses may only fire once or twice, although there will be a good 
number of parallel processes, from jerking your hand away to filling 
the nieghboring air with Fanciful Language.
 
 In the case of the optic nervous process, then the potentials are 
firing quite rapidly, upward of 100 Htz for each nerve in the optic 
bundle.
 
 But the main reeason for my alarmed screed  is still the very 
dangerous lack of a basic understanding of the hows and whys of 
electrical safety (as it applies to our rather dangerous hobby) 
evidenced by the original posting's premise that shock hazards and 
electrocution danger could in any way be mitigated by raising the 
mains frequency.
 
 Not to mention that a line F of 1Khtz would make my old clocks run 
really really fast, and there's barely enough time to get Stuff done 
as it is.  Perhaps that's my subconcious reason....
