The water hand-pump
with pendulum
Veljko Milkovic is a Serbian inventor living
in Novi Sad, who has several inventions and patents in the field of
alternative energetics and ecology. He has demonstrated his invention in
practice on all major technical reviews in Serbia. On the Tesla-festival in
October 2002 held in Novi Sad he has demonstrated a working model of a water
hand pump with a pendulum, which delivers more energy than what is required
for its operation.
The device has been made of exclusively
recycled materials to show that it can be realized with extremely cheap
materials in an environment friendly way. It consists of a commercial water
hand-pump, a double lever, and a pendulum as shown in the picture below.
The double lever is made of a reused 3/4
size kid’s bike-frame, and the pendulum (red) is an old piston of a big
diesel motor combined with a heavy block of iron.
Significant manual work is required from the
operator to pump the water directly with the hand-pump, and one is getting
tired after continuous prolonged pumping. The same pumping work can be
accomplished with much less invested energy if the arm of the pump is
attached to one side of the double lever, and the pendulum at the other side
is kept in motion by manually giving a slight push to it every few cycles
(10-20 sec.).
Milkovic states that his double pendulum (or
multilevel oscillator) generates about 12 times more output energy than the
manual input energy required to keep the pendulum swinging. The rough
translation of some excerpts from his Serbian patent (from the book
“Perpetuum Mobile” by Veljko Milkovic and Nebojsa Simin) is given below.
Water
Hand-Pump With Pendulum
The essence of the invention:
The essence of the invention is that the
vertical up-down moving of the piston through a system of levers is done
indirectly with the help of a pendulum attached to the end of the double
lever, where otherwise with the already existing solutions we would act with
hands.
In order to move the piston and lever up and
down it is necessary only to give the pendulum a push that represents much
less effort than the direct action on the lever, since this way besides
human power, the power of gravitational potential is also used as driving
power. The action of the hands is required only now and then due to the
friction resistance to maintain the amplitude of the oscillation for a
continuous intensity of water flow. The pump is functional with all
amplitudes, but the best performance is achieved with an amplitude of about
90° . Additional advantages of this pump compared to the already existing
solutions are:
 | After giving a swing to the pendulum both
hands are free to handle the water. |
| The pendulum can also be a children’s
swing, so that useful work can be also done through playing. |
Detailed description of the invention:
The figures show the water hand-pump with
pendulum, which is made of cylinder (1) with the piston (2), the system of
levers (3), see-saw (4), and pendulum (5).
In order that the see-saw and the piston
would also oscillate together with the pendulum, the side with the piston
should be heavier than the side with the pendulum, and for the best
performance about 50% heavier than the centrifugal force of the pendulum,
which appears when its swinging amplitude is 90° . If the two sides of the
see-saw are not of the same length, it is necessary to do calculations
through the moment of forces around the point where the see-saw is resting
on the support.
In accordance with the spirit of the
invention, when the pendulum is in rest, or during the swinging it is at the
upper points of the amplitude, the piston with the system of levers will
overweigh the other side of the see-saw with the pendulum, and it will fall
into the lower point. The piston will rise to the highest point when the
pendulum passes through the bottom vertical position during the swinging,
because in these moments the centrifugal force of the pendulum will also act
besides the weight, and since their sum is bigger than the weight of the
piston, they will overweigh on the see-saw and in this phase the piston will
push the water out of the container (6) into the outlet pipe (7).
In accordance with the preferred embodiment
of the invention, in order to start the flow of water from the pump it is
necessary to move the pendulum out of the equilibrium, after which an
oscillatory movement of the piston is established, and a continuous flow of
water results. Due to the friction resistance, the pendulum should be pushed
by the hands only now and then in order to maintain the amplitude of
swinging and continuous intensity of water flow.
The pump is functional with all amplitudes
of the pendulum, but primarily with an amplitude of 90° .
The advantage of this invention compared to
the already existing solutions of hand-pumps are: less manual force needed
to operate the pump, less waste of water, and both hands can be used to
handle the water.

CONCLUSIONS
Models of perpetuum mobile and inertial engine described
in this book are based on the effects of the forces of inertia. In fact, ten
inventions are described which are, in mechanical sense, multi-level
oscillators operating together. The first oscillator in the series is a
physical pendulum or an eccentric fly-wheel, the second is a lever or a
wheel, and the third is the base (the ground, a vehicle or an aircraft). The
movement of the first oscillator causes forced oscillation of the next
oscillator in the series.
The author of the first nine inventions is Veljko Milkovic. These
inventions are actually different possibilities of application of the
multi-level oscillator:
1. Water hand pump with pendulum
2. Fan with pendulum
3. Mechanical hammer with adaptable pendulum weight
4. Press with pendulum and magnets
5. Water pump with pendulum and electromagnets
6. Electrogenerator with pendulum and magnetic buffers
7. Wind propelled electrodynamo and gravitational potential
8. Electrodynamo with elastic pendulum handle
9. Electrodynamo with double lever and eccentric mass windmill.
The author of the tenth invention is Nebojsa Simin. This invention is a
universal device for power generation and movement by inertia:
10. Electrodynamo with eccentric flywheel and electric motor.
The perpetuum mobile is based on the work of the second oscillator which
obtains power solely due to the movement of the first oscillator it is
connected to, and not its work. That is how the law on preservation of
energy loses its validity. This occurs due to the fact that the first
oscillator is connected to the second one via the reference point of the
system of reference in which the second oscillator moves. The force of
inertia that causes forced oscillation of the lever or the wheel is the
centrifugal force of the pendulum or the eccentric fly-wheel which is
responsible for the oscillation of the lever or the wheel, but does not
perform work in order to cause oscillation of the physical pendulum or
rotation of the eccentric fly-wheel.
The inertial engine operates thanks to the centrifugal
force which affects the mass center of the wheel during forced oscillation
around the determined balanced position. Therefore it also affects the base.
The work of this force of privileged direction does not affect the
oscillation of the wheel, so its operation in the reference system in which
the wheel oscillates is equal to zero. However, the same force affects the
reference body of the system in which the wheel oscillates, that is the
base. In this way, the wheel together with the base accelerates in reference
to an imagined inertial system of reference. In relation to the Earth the
direction of this acceleration can either be horizontal or vertical. In case
it is horizontal the engine can be used in ground transportation. In case it
is vertical, it is an anti-gravitational engine. In fact the inertial engine
accelerates in relation to any point in the Universe, in other words it can
operate even in the conditions of zero gravity. This means that this engine
can move an aircraft in a desired direction without using reactive fuel.
The perpetuum mobile and the inertial engine do not use external sources
of energy except at the moment of starting its operation. This significantly
changes the situation concerning power supply and environment protection in
relation to the currently known one.”
