OK. Half the pulses, half the power. Forget the time. Same thing.

Let's say you have a steam engine with one single action cylinder.
Assume a perfect flywheel, no parasitic loads (such as bearings),
an unlimited supply of steam at a constant pressure (the functional
equivalent of our 60 hz power), and a static load such as a coal 
elevator conveyor (the resistance of our filaments).

In operation, the single action cylinder pushes through one half
revolution and coasts through the other. Now you either convert
the cylinder to double action, or add another single action cylinder
to "push" on the other half revolution while the first cylinder is
"coasting".
The load of coal will now have to be doubled (dissipating more energy)
in order to maintain the same RPM as before, or the conveyor will
run twice as fast...either way you get twice as much coal. The engine
will NOT generate THREE times the power and give you three times
the amount of coal.

Adding the second cylinder action in this example is the same thing as
"removing" the diode in our electronic equivalent. That is why a V8
engine (for the most part) only generates eight times the power of
a single cylinder engine of one eighth the displacement. Otherwise,
instead of generating, say, 240 HP, it would generate 540 HP.

And so we end up here in the back stretch talking about horses...
