Background Art. Nowadays there are several ways of producing electricity but all with some kind of problem: water, wind and sun aren't always available everywhere and, in some places where they are available, they often depend on weather conditions; fuels like coal, oil and others, besides polluting the environment, aren't endless.

The magnetic-powered engine is expected to give an answer to all the problems mentioned in the previous paragraph. To build it you need three main things: gears, nonferrous metals-like certain types of stainless steel-because they aren't affected by magnets, and permanent magnets. It is easy to find the gears and the nonferrous metals that you need. Permanent magnets are the most important part of the engine and you should try to find the most powerful type that can operate in the repulsion position, and the company or firm that can magnetize the largest size possible. It is also important that the axis of the magnet be in the shortest edge so that the magnetic south and north poles, i. e., the main attraction/repulsion surfaces, would be the largest sides: for example, if you have a size 150mm x 100mm x 20mm axis magnet, its magnetic south and north poles will be the ones with the 150mm x 100mm size. According to recently gathered information neodymium permanent magnets are the most powerful available that can function in the repulsion position.

These magnets will only lose their power if they reach the temperature of approximately 100 degrees centigrade, which is very unlikely to happen as the engine isn't expected to reach even half that temperature. Taking into account nowadays technological evolution you should pay attention to new discoveries in the permanent magnets field.

Disclosure of Invention. The magnetic-powered engine should have one main axis/cylinder and at least one secondary axis/cylinder, each axis/cylinder-both main and secondary-having at least one arm fixed in a perpendicular/oblique position to the axis. At the furthest end of each arm there will be a permanent magnet : the magnets of the main axis/cylinder should be fixed to one side at the furthest end of the arm, while the magnets of the secondary axes/cylinders should be fixed to the furthest top of the arm. The secondary axes/cylinders should be placed preferably in a parallel position all around and at the same distance from the main axis/cylinder.

All axes/cylinders should have a circular movement around their own axis in such a way that the secondary axes/cylinders would move in an opposed direction to the main axis/cylinder, i. e., if the main axis/cylinder has a clockwise movement, the secondary axes/cylinders must have an anti-clockwise movement and vice-versa.

These movements should be controlled by a gear-toothed wheels with or without chain (s)-in such a way that the movement of the secondary axes/cylinders would preferably be two, three, or more, times the movement of the main axis/cylinder, i. e., the toothed wheel fixed to the main axis/cylinder would have two, three, four, or more, teeth than the toothed wheels fixed to the secondary axes/cylinders.

During these controlled movements each magnet of the secondary axes/cylinders will meet regularly at a very short distance the same magnetic pole surface of a main axis/cylinder magnet-either a south pole surface will meet another south pole surface or a north pole surface will meet another north pole surface, according to the position of the magnets, and cause a repulsion force in two opposed directions. The force over the secondary axis/cylinder will be in the direction of its axis, which acts as an obstacle, and will have almost no effect over the whole movement. The force over the main axis/cylinder will be perpendicular/oblique to its arm, making it withdraw and have a circular movement, causing this way the whole engine to move round.

Each opposed force created when two magnets move very close to each other can be considered an impulsion point/moment in the engine. You can create stronger or weaker impulsion points/moments: the bigger the magnets are, the stronger the impulsion points/moments will be. You can also decrease or increase the number of impulsion points/moments, and make them act one at a time or several at each moment, by varying the number of secondary axes/cylinders and/or the number and position of their arms.

It is still possible to give the engine different accelerations to its movement by varying the proximity of the magnets in their impulsion points/moments. There are several ways of controlling the engine acceleration.

One of the main reasons for the secondary cylinders arms to move faster is that they will have to follow a moving main cylinder arm with enough speed to reach its magnet in the impulsion position. Besides, this can also improve the engine acceleration.

As the central toothed wheel can have two, three, four, or more, teeth than the surrounding toothed wheels in the gear, you should, respectively, use two, three, four, or more, arms lined in the same line of action in the main axis/cylinder and separated from each other by the same angle. This way, each secondary cylinder arm can meet two, three, four, or more, main cylinder arms at their impulsion points/moments.

There is also the possibility of having several series of arms, each series lined in the same line of action, and organize the position of all arms in the engine to synchronize the impulsion points/moments. For example, imagine you decide to build an engine in which the central toothed wheel of the gear will have three times more teeth than the surrounding toothed wheels, so that it would turn once while the others would turn three times, and you also decide to build four series of arms. You would have three secondary axes/cylinders, with four arms each, surrounding one main axis/cylinder which would have four groups of three arms-a total number of twelve arms-, being these three arms separated by 120° from each other. In each series you would have six arms creating impulsion points/moments among them-three arms in the main axis/cylinder and one in each of the three secondary axes/cylinders.

Finally you could still build separate engines and join them later, thus creating a more complex and very strong structure. There are many possibilities.

Brief Description of Drawings. So that this invention can be better understood, here is a brief description of the drawings.

Fig. 1 shows a possible magnet-powered engine consisting of one main cylinder (MC) and two secondary cylinders (SC1 ; SC2). The main cylinder has got four pairs of arms making a total number of eight arms, while the secondary cylinders have four arms each. To control the movement of this engine you could choose one of the two types of gears (Gl ; G2) which would cause the secondary cylinders to move round two times while the main one would do it only one time. At this moment in this figure you have two impulsion points/moments at the same time: one is caused by the proximity of two magnets (MI ; M2) at the end of two arms (A1 ; A2), and the other is caused by the proximity of two other magnets at the end of other arms (A3; A4).

These four arms (Al, A2, A3, A4), which belong to the same series, are in the same line of action and cause two impulsion points/moments at the same time. The other three series of arms belonging to three different lines of action will act in three different moments, and will create two impulsion points/moments at the same time each. According to the figure, the main cylinder is supposed to have a clockwise movement, while the secondary cylinders should have an anti-clockwise movement.

Fig. 2 is here to show that when you shorten a cylinder arm you decrease the speed of its furthest end, which can cause some problems. In a circle with an anti- clockwise movement, dot 1 (Dl) is slower in its movement to dot 2 (D2) than dot 3 (D3) in its movement to dot 4 (D4), because the distance is shorter but takes the same time to be run. You should be careful if you have to shorten the length of a secondary axis/cylinder arm because it must follow a main axis/cylinder arm with enough speed to be in time in the impulsion position. To avoid this problem, for example, instead of using in the gear a central toothed wheel with two times more teeth than the others, you can choose one with three or four times more teeth but not forgetting to make all the necessary changes to the whole engine.

Fig. 3, Fig. 4, Fig. 5 and Fig. 6 are intended to help describe different ways of creating an acceleration structure which would vary the proximity of the magnets in the impulsion position.

One of the acceleration structures is based on wedges but it can be a little complex or even fragile. Fig. 3 could be an example of part of a secondary cylinder where you can see an axis (AX), a metallic tube (T), a supporting piece (S), an arm (A), and a wedge (W). The wedge would move between two ball-bearings-one fixed to the supporting piece and the other fixed to the nearest end of the arm-and make the arm and its magnet move forward or backward. Fig. 4 could be an example of a main cylinder (MC) where you can see two wedges (Wl ; W2), a metallic piece (P) fixed to a large arm, and another small arm (A) with a magnet. In this case, wedge 1 (W1) would move between two ball-bearings-one fixed to the cylinder and the other fixed to the base of wedge 2 (W2)-making wedge 2 move between two ball- bearings-one fixed to the metallic piece (P) and the other fixed to the small arm (A) -making this arm and its magnet move backward and forward. Fig. 5 shows a wedge structure with four wedges (W) fixed to a ring (Rl)-which could be used at the top of a cylinder and move round with it-, and another ring (R2) with four ball-bearings (B)-which could be used to push the first ring (Rl). Notice that you could avoid the second ring and its ball-bearings by using a ball-bearing that permits lateral pressure.

Fig. 6 is supposed to show two different and better ways of accelerating the engine. This figure shows a main cylinder that would have a central cylinder or axis (C/A), and an outer cylinder (OC) where the arms would be fixed. One of the solutions would be by causing the outer cylinder to make very short movements (MV1) to the left or to the right around the central axis. Another solution would be by causing the outer cylinder to make a movement (MV2) along the central axis, thus approaching or withdrawing from the line of action where the secondary cylinders arms are expected to move and have impulsion points/moments. Nowadays technology permits both movements (MV1; MV2).

Fig. 7 is an example of an engine with a main axis/cylinder (MC) and four secondary axes/cylinders (SC1 ; SC2; SC3; SC4). In this case you would have four impulsion points/moments at the same time. This figure doesn't show the number of series of arms lined in the same line of action, which could vary according to your needs.

Fig. 8 is similar to Fig. 7. The difference is that the arms of the main cylinder (MC) are longer.

Fig. 9 is similar to Fig. 8, but the secondary axes/cylinders have two different impulsion moments: two secondary cylinders (SC1 ; SC2) have an impulsion at the same time while other two secondary cylinders (SC3; SC4) have an impulsion together at a different moment from the previous two.

Fig. 10 has 8 secondary cylinders acting four together each time in two different moments: four cylinders (SC1 ; SC2; SC3; SC4) act together in one moment; four cylinders (SC5 ; SC6; SC7; SC8) act together in another moment.

Fig. 11 shows a different structure that could be useful in certain situations where space has certain limitations. The secondary cylinders (SC) function perpendicularly to the main cylinder (MC). The pieces (AX) are supposed to be the axes of the different cylinders. The number of secondary cylinders (SC) could vary.

Best Mode for Carrying Out the Invention. Taking into account that this engine can have many different structures to reach different needs, it isn't easy to define the best mode for carrying out the invention. Anyway it is possible to give some advices.

The most important thing in an engine is the power of the magnets, which can be limited by the space available. The bigger the magnets are, the stronger they will be. Now imagine that you have size 150mm x 100mm x 20mm axis magnets. If you join the magnetic south surface of one of them to the magnetic north surface of another, they will attract each other and form a size 150mm x 100mm x 40mm axis magnet, i. e., they will form a more powerful magnet. But you can join another magnet to get a size 150mm x 100mm x 60mm axis magnet. This means that you can build stronger magnets than those that you got. Now you only need to enclose them in nonferrous metals, for example, nonferrous stainless steel. But notice that you can't use heat to enclose the magnets because they will lose their power if they reach a certain temperature.

Another important thing is the number of impulsion points/moments at the same time. The more they are, the stronger the engine will be. It can depend on your needs and on the space available.

The acceleration structure based on wedges, mainly in the smaller engines, should only be used if there isn't another solution: besides being a little complex or even fragile, the structure of the secondary cylinders, as shown in Fig. 3, would limit the length of the main cylinder arms and the engine power. The main cylinder arms should move as near the secondary cylinders axes as possible.

For smaller engines, a good structure would be one based on Fig. 8 or Fig. 9 with four series of arms.

Industrial Applicability. This magnetic-powered engine can be used in two different ways.

It can be enclosed, as a source of motive energy, in an electric generator to produce electricity for an electricity-supplying company/firm, a city, a town, a village, a group of buildings, a factory, a house, or even some means of transport where there is enough space available like ships, trains, planes, and so on.

It can be used alone as the only source of motive energy to move certain machines or devices, for example, to move a structure of buckets/vessels to take water from a well/pond/river.
