by waves, undulations, the streams etc. The device according to
the invention, aims at supplying a means of Navigation's
appropriate (clean), easy to practice; it can be Additional in
the other means of navigation's.
The device according to this invention allows the navigation. By
converting the Bi-directional Kinetic energy of movements, the
oscillations, right-left an/or front-back and/or high/down .To a
Uni-directional (one-way) horizontal push. These energies are
free,renewable undeveloped in navigations up to day. They have

In fact, any variation of the boat level is attenuated and
converted to a uni-directional(One-way) horizontal push. This
device converting the Bi-directional Kinetic Energy (up/down),
to a horizontal Kinetic Energy (one-way) A similar device is
used in the aviation for a century with the success. But in a
opposite applications. The Aircraft manufacturers, the power
developed by Engines, reactors pushing in front the Air-plane.
The arrangement of wings and the position of lids, convert a
part(party) of this power in a vertical push. Also Gliders
convert the current of the ascending air(sight) and or while

Francois Kneider's Wave Powered Boat Working Principles
While about a month ago I was presenting an article about
Suntory Mermaid II, a boat powered only by the movement of the
waves, I am now presenting an inventor, named Francois Kneider,
who in his seventies, continues to amaze the people who know him
by the number of ideas he has and the innovations he brought to
life. In 2005, he focused on building wave powered systems for
He has made concepts that shouldn’t work according to
conventional theories and practices. When examining his
demonstration of his cold cathode tube, the head of an
electrical company told him, “It should not work!” while
admitting that it did. Kneider compared this achievement
to Newton’s apple remaining suspended in the air, as opposed to
landing on his head.
Kneider’s idea was to convert a vertical moving wave to push the
boat on the horizontal. The following images demonstrate the
Mr. Kneider is disappointed by the current progress in battery
technologies (as of 2005), instead he says we should use
self-generated power onboard our boats, because this kind of
energy usage is the greenest and the most efficient (nothing is
lost as heat or other forms of energy).
Below is an example of a boat modified to suit the idea of
self-power. The first example is the boat with the blades set
for powering it, and the second is the case when, during a
storm, the blades are raised for not being torn apart (the
energy is higher than the system can bear, like in the video of
the wind turbine torn apart by high velocity winds) – click to

Mr. Kneider also put a comment on this blog for me to check out
his website and inventions posted on PESN. I thank him for that
matter. Great inventions!
Motor for sailing using wave energy

IPC: B63H1/36; B63H19/02; B63H1/00
Abstract -- The invention relates to a device
for sailing using wave energy, by converting the up-down linear
movement into a horizontal directional thrust. The element B can
tilt and is fitted with two stops K and L. Any thrust generated
by the element A is converted into a horizontal thrust by the
element B in the direction of the arrow F. The device according
to the invention is particularly intended for moving boats by
Present invention relates to a motor of navigation functioning
with the energy of the waves, swell, floods, corrugations etc. ,
sailing on a sea, a lake, an ocean, or any water surface
agitated by waves. One knows already the technical ones used in
the field of the navigation, using power plants, and sailboats.
The heat energies are generally crude and generate pollution.
Sailboats are very widespread, but they present also have
disadvantages, for example: to go against the wind, and
difficulties of management. The energies of the waves are
practiced only on the surfing in a way very limited for
The apparatus described in this invention, aims at providing
means of navigation that is clean and easy to practice, and it
can be complementary with the other means quoted above.
The apparatus in accordance with the invention particularly
makes it possible to be freed from constrained from the heat
energies, and the disadvantages of the navigation with sail and
the difficult character of surfing. With this aim, the invention
proposes essentially navigation means with the energies of the
waves, more exactly the energies generated on a floating member
giving it a straight movement of high downwards, and the low one
upwards; this straight movement of high downwards, and low
upwards conceals a substantial source of potential energy not
exploited before this invention. This phenomenon of straight
movement present a maximum amplitude with the water surface, and
progressively attenuates while going towards the depth, this
attenuation is relatively progressive, it will reach agitating
zero with a few metres of the water surface, therefore there is
a difference in agitating going of high to the bottom, that is
to say a potential difference in energy.
The apparatus in accordance with the invention aims at
exploiting this potential difference by proposing a practical
and economic apparatus converting this energy resultant of the
straight movement into an horizontal thrust in a given
direction, from where a motor functioning with the energies of
the waves, by attenuating the high-low movement.
The present invention is characterized as follows: It includes
member A (see PL1 Fig.l) floating with the water surface being
at the maximum point of agitation, a second member B placed in
the submerged part at some distance from the agitating maximum,
towards zero agitation .
B, represents the converter element of the rectilinear energy
giving directional thrust. To understand the object of the
invention, we suppose that the part B is submerged with the
vicinity of agitating zero. The part B consisted a member
resembling with a pivotal plank on an axis C, being between the
center of gravity of this plank and its end. Any thrust of
member A of high to the bottom generates a thrust of the member
B in the same direction, tilting the plank B and by positioning
the high part D compared to the part E bass, that one would
cause an horizontal thrust in the direction of the arrow F (see
PL1 - Fig.l)
Any thrust of member A, low to the top would rock the member D
of the plank B to the bottom, and the part E to the top would
continue a thrust in the direction of the arrow F, so each
high-low straight movement and vice versa causes a thrust in the
same direction. To choose its direction, it is enough to
position the plank B via the member G in the wanted direction,
independently of the direction of the waves and winds. Speed of
displacement of this boat, boat etc, depends on the members
following: the amplitude of the waves, the surface with element
B and the angle of its pivot, its optimum depth, and resistance
of the whole to the movements. This angle of swivels perhaps
lies controlled by fixed stops and/or variable, placed to have
the angle getting the optimum thrust. (see PL2 3-4). The angle
the zero, i.e. plank B remaining immovable on its axis causes a
thrust of the for these equal in two opposed directions, from
where thrust EGA is zero. The change of a given angle would
involve one thrust in the indicated direction and the proximity
of it B compared to the point of agitating zero lies determines
pushed. The member B is described in only one member for faci
liter the description and the comprehension of the invention.
The member B perhaps carried out in 1-2-3-4, etc., infinite
numbers of elements. Numbers of the members and theirs sizes can
be given by requirements of price, weight, effectiveness, size
of the boat, ship, etc. Speed and the cost of construction will
determine the numbers of members B and their sizes.
The adaptation of several members B directed in way that the
thrusts being opposed the ones to the others in a skilful way
generated the fixity of member A independently of the waves and
The member H is presented in a pivotal bar, which perhaps
realized by a fixed bar or flexible rope.
The apparatus in accordance with the invention cannot function
without the agitating of the waves. One can assist it by a motor
auxiliary which would be used for at this time to enter and
leave ports in particular.
The apparatus in accordance with the invention can find a
considerable application in the field of the navigation, boat,
boat, vessel, building, ship, platforms, etc., serving either
with their movements or with their fixing. The overall
construction can be carried out with steel, wood, synthetic and
various products, for example: semi-flexible materials
like the fins (used by divers) by the fact of their semi-rigid
constitution, would make member B funtion without a pivot,
although the efficiency is lesser.
