BACKGROUND
In regard to the contents of:
http://www.mtaonline.net/~hheffner/CasimirGenerator.pdf
the lateral Casimir force between a square plate edge and an adjecent
parallel plate is not the same as for a beveled plate edge and
opposing plate, and thus a net energy gain is feasible from a Casimir
effect motor, provided the edges of the plates are appropriately
shaped. I showed, by comparative analysis, that the lateral Casimir
force due to forces between a square plate edge and an adjecent
parallel plate is not the same as for a beveled plate edge and
opposing plate, and thus a net energy gain is feasible from a Casimir
effect motor provided the edges of the plates are appropriately
shaped. It is thus feasible to build a motor rotor consisting merely
of a parallelogram shaped lobes, and stator which is merely a flat
surface near which the rotor rotates. The gap between stator and
rotor have to be very small.
SMOOTH SURFACE ROTOR CONCEPT
It might of use to make the stator a surface with non-symmetrical
cross section grooves or fairly closely spaced parallelogram cross
section "blades". Call this the activator surface. Such a surface
could be relatively large in area. Then the rotor or armature need
only provide a closely mated smooth surface at a very small distance
from the stator. The activator surface could be planar, or
cylindrical, or conical, etc., with the *rotor* (armature) shaped to
mate surfaces.
PENDULUM CONCEPTS
It is easier to build oscillating arm (pendulum)
MicroEletroMechanical system (MEMS) devices than similar devices with
rotors because it eliminates the need for bearings, and the
construction can be achieved using existing electronic chip making
technology. A linear motion armature pendulum could be activated by
changing the distance between the stator and armature in one
direction, the y direction, in order to initiate free energy motion
in the other. An x axis moving armature (drone plate) sandwiched
between two physically connected activator (drive) plates that move
together in the y axis, one growing closer to the armature as the
other recedes, each activator plate with groove shapes oriented to
cause forces on the armature (drone plate) in a direction opposed to
the other activator plate, would cause the armature to oscillate in
the x direction, with net energy gained from each oscillation. Since
the y axis force times distance curves integrate to the same energy
value of zero, no net energy is required to drive the activator plate
pendulums, other than heating due to friction and torsion. The
physical linkage of opposed driver plates reduces the electrical
energy required to drive them. Electrical energy can be extracted
from the induced x axis linear armature motion by having it change
the separation between charged capacitor plates, or by having a
connected dielectric material move in and out of the volume between
two charged capacitor plates, i.e. by driving an electrostatic AC
generator. Similarly, some of the generated energy could be fed back
to capacitively drive the motion of the activator plates.
MACRO AND SYNCHRONOUS MOTION CONCEPTS
There is a potentially practical means to derive macro levels of
energy from an array of MEMS devices similar to those described
above. This practical means is to use capacitive linkages to drive
the y axis oscillations of all the paired driver plate pendulums so
as to synchronously drive all the pendulum oscillations in a large
array. This synchronous action of all the pendulums then will cause a
macro level vibration in the array which can be used to obtain macro
levels of free kinetic energy. Such energy might be converted to
electrical energy by driving piezoelectric crystals connected to a
very large array. Electrical energy so obtained can then be fed back
to the oscillator driving the driver plate pendulums. Alternatively,
the synchronously oscillating drone places could drive capacitive
generators to produce a synchronous current output. Elements of the
array could be joined in series and parallel to obtain useful power
levels. The power output of such a MEMS array would be radio
frequency.
LARGE PLANAR MASS PENDULUM WITH PIEZO DRIVEN STATOR (LPMPPDS)
A macro sized x axis moving planar mass pendulum armature, supported
by numerous flexible supports, arrayed in the xz plane behind the
pendulum mass plane, could be driven by a y axis approach of a stator
plane containing numerous parallelogram shaped grooves. The stator a
armature surface planes lie in parallel xz planes. The stator plane
could be driven via piezo effect. Fig. 1 shows a cross section view.
A principal advantage of this design is the degree of precise control
of plate surface (Z and M) separation, and surface approach rate, of
the stator to the pendulum surface, obtained by use of the
piezoelectric effect to control spacing. A second advantage is that
the pendulum supporting pillars draw the pendulum away from the
stator if motion becomes extreme, thus providing some degree of
control. A third advantage of this design is that the pendulum
motion area and motion is coordinated at a macro level. The pendulum
material M, or even the substrate S, can be connected to an
electrostatic or piezo electric generator, which provides feedback
power to the stator piezo drive.
