these facts were also testified to in Congressional Hearing in 1906 and the oil
industry was never able to refute the information.

THE AMOUNT OF WORK IT TAKES TO LIFT A ONE-TON BLOCK IS THE
SAME WITH OR WITHOUT A PULLEY!!!! If you lift a one-ton block 1 meter off
the ground, you have applied the same amount of energy to that block with or
without a pulley!!!! With a pulley, it took twice the amount of TIME to do it, therefore your energy PER SECOND decreased, but the TOTAL AMOUNT of work
done IS THE SAME!!!!!
A 1-ton block that is 1 meter off the ground has the same amount of potential
energy NO MATTER HOW IT GOT TO BE ONE METER OFF THE GROUND!!!
If you lifted it directly, or if you lifted it with a pulley, IT HAS THE SAME
AMOUNT OF POTENTIAL ENERGY!!!!!!!!
Reply from MARC:
You made a good point, separating the difference between "energy" required
and the "force" used in the example of lifting a block of cement. However, in
doing so you help prove the point as to how and why BTUs are irrelevant for
internal combustion engines.
One of the 3 characteristics that are different in an ethanol-optimized engine is
that it has a longer piston stoke. The longer piston stroke provides more force.
Gasoline, even with its higher BTUs can't effectively push the piston in an ethanol-optimized engine. With this extra force, an ethanol-optimized engine/car
can travel faster and further on the same volume of liquid fuel (ethanol vs. gasoline).
Conversely, ethanol doesn't effectively utilize the shorter piston stroke and
spark timing of a gasoline-optimized engine, so it uses more fuel to accomplish
the same task.
Therefore, it is as I've maintained, engine optimization and not BTUs is the key.
And the example that higher BTU diesel fuel can't be used in a gasoline engine
