Perpetual motion machine #3
How it doesn't work
As I explained in my description, the problem with this machine is not
the three ficticious devices. They are theoretically possible. However,
what is not possible is to move light upwards in a gravitational field
without it red-shifting. The weight at ground level would be converted
to light with a certain energy. As the light moved upwards it would become
less energetic by the exact amount equal to the potential energy it would
gain by its mass equivalent moving upward. Therefore, when the one ton
weight is converted to light at ground level and back from light at
a higher level, it weighs less! The maximum energy that can be extracted
from the machine is the energy that 1 ton has when converted to light.
Oh, and for the pedantic, yes, strictly speaking 1 ton is a weight, not a mass.
