Hi
I remembered a perfect example of resonance in our real life: The child's Swing.

The swing has a natural frequency at which it oscillates. This frequency is formed by the length of the rope and the acceleration of gravity(g) (so much like a pendulum). So we just use the correct impulse at the right time to make the swing go faster and faster each time. This is what makes us use very small amount of energy for making the child swing faster. We never push the child when he is coming towards us, but when it is "starting" to move away. This is the resonance frequency of the swing.

So Pulsing or applying a sine wave force to a natural oscillating element with its resonant frequency is the most wise thing to do!! When we aren't we are just wasting energy by pushing and pulling to shape the natural world around us and making things difficult, instead of applying an impulse at the right time and being one with it.

Bedini's Battery chargers seem to work like this too, but I have never understood exactly how he found the resonant frequency of the batteries to pulse them at the right moment. I only remembered somewhere reading about this fact. He never told us clearly, but I think that what he meant by pulsing the battery at the right time and tuning the chargers, was this. It would be nice if someone could explain how he found the resonance frequency of the batteries.
