I don't believe that statement is entirely accurate.
Take one of those little hobby motors for R/C cars...
Put A/C on one of those and it'll just sit there a jiggle...depending on the A/C frequency of course...and the voltage...as stated above it could become a backlight...and a short term heater...and possibly a insect defogger...or get rid of annoying kids...
