I tell you what. Why don't you build one of these magic modulators, show us
that it works, and then we'll believe you.
If it does, I might be encouraged to have a go at making that machine I
invented at the age of about seven, even though my dad told me it wouldn't
work. My plan was to use an electric motor to turn a dynamo, which would
generate electricity, which would then be used to power the electric motor.
After it had been patiently explained to me that the amount of electricity
generated would not be enough to power the motor, my next idea was to
interpose some gears or pulleys so that the motor would turn the generator
a little faster, thereby generating more electricity. My understanding of
the physical world had some way to go, but we all have to start somewhere.
Rod.
