A Promethean Thought Experiment
The Alstom made X40 electric passenger train has a powertoweight
ratio of 12 watt per kg (2.400 kW / 205 tons) and a maximum speed of
200 km/h (
fig. 9,
fig. 10).
Suppose one would flatten an X 40 electric passenger train into a disk
of 205 tons with a diameter of 20 meters, fit it with inwheel electric
traction motors and put it on a pivot and a circular rail (
fig. 1,
fig.
2). Would the powertoweight ratio of 12 watt
per kg of X 40 train, which has a maximum speed of 200 km/h, be enough to give the disk a speed of 45 km/h
(measured at the disk's edge) and rotating it 12 times per minute?
Would this be possible? Why would it not be possible? The disk has the same weight as the X40 electric train and is
subject to rolling resistance, aerodynamic drag etc. just like the X40
train is. Therefore, the 12 watt per kg powertoweight ratio should
work for both.

Next, by fitting permanent magnets on the edge of the disk and by
building an ironless stator around the disk, the disk turns into a
generator (
fig. 3,
fig. 4). Will a 12 watt per kg powertoweight
ratio (2.400 kW) still be enough to spin the disk at 12 rpm, giving it at a speed
of ~ 45 km/h (measured at the disk's edge)?
If this is possible, it just
generated excess energy! Please do not feel fooled and continue reading.
The details like the disk's diameter of 20 meters, the disk spinning at 12 rpm and the
disk's speed of 45 km/h measured at its edge, are not random picks,
but are data from a science paper on a wind turbine generator (
fig. 7,
fig.
8). The generator's rotor has the same diameter, rpm
and travels at the same speed as the disk.
This generator (rotor and
stator)
weighs
145 tons and
can
generate 10 MW (10.000 kW). The disk / rotor (
fig. 1,
fig.
2, (
fig. 3 ,
fig. 4)
weighs
205 tons and
consumes
2.400 kW power. This means there is a net output 7.600 kW of excess energy.
The
laws
of thermodynamics rule out excess energy. So, where did all the
power go? Surely, there is some mechanical loss created by the disk
spinning around the pivot, but does that gobble up 7.600 kW?
Rolling
resistance and aerodynamic drag are already covered by the
powertoweight ratio of 12 watt/kg (2.400 kW). Furthermore, full power
(2.400 kW) is only needed to drive at its maximum speed of 200 km/h. The
disk / rotor only needs to drive at 45 km/h in order to generate 10.000
kW.
Do forces like hysteresis or eddy
currents create an "electromagnetic drag" that takes 7.600 kW of power
to overcome? That is enough power to run another three X40 electric
trains! Each X40 electric train weighs 205 tons! The margins look large
enough to suggest up to 7.600 kW of excess energy is plausible.
It is possible to increase these margins by remodeling the way the disk is
powered (
fig. 4,
fig. 5). The wheels are made stationary and fitted in a circle, just like the wheel train in
fig. 11. The electric motors are fitted with a pinion gear that drive an internal ring gear
or pin gear (
fig. 12 ,
fig. 13) fitted on top and close the edge of the disk. This saves quite some weight since electric motors and steel wheels are heavy.
What
do you think? Did the thought experiment make the generation of
excess energy plausible? If you want to share your views you can do so via
