Hi Mike,

My guess for NOT doing this would be the exhorbitant cost of changing the
entire power grid to higher frequency not to mention EVERY electrical ap-
pliance that you own would suddenly become obsolete. Also, I'm sure there
would be excessive skin-effect losses with trying to run  several kHz on
long distance transmission lines, not to mention the larger insulator re-
quirements.
