## Abstract

An electrical generator powered by the rotation of a central shaft. A gear train rotates with respect to the central shaft and is in operable connection to a generator for producing electrical energy. The shaft can be rotated by falling weights connected to longitudinal arms. Alternatively, a motor can be used to rotate a relatively large wheel in operable connection with the series of gears or gear train. Additionally, the shaft can be rotated by a renewable energy source, such as wind or water.

## Claims

### Claim 1

A device for producing electrical energy, comprising:
an electrical generator provided with a plurality of poles and coils, and a first rotatable shaft;
a gear train including a plurality of intermeshing gears, a first of said gears in rotational communication with said first rotating shaft of said electrical generator;
a lever connected to said first rotating shaft; and
a vehicle directly pushing said lever along a circular track and thereby causing rotation of said gear train, the rotation of said first rotating shaft transferred to said electrical generator by the rotation of said gear train to produce electrical energy;
wherein the speed of rotation of said first rotating shaft is a function of the number of poles and coils provided in said electrical generator.

### Claim 2 (depends on 1)

The device in accordance with claim 1, wherein said electrical generator is provided with two poles/coils, thereby requiring a rotation speed of said first rotating shaft to be 3600 rpm.

### Claim 3 (depends on 1)

The device in accordance with claim 1, wherein said electrical generator is provided with four poles/coils, thereby requiring a rotation speed of said first rotating shaft to be 1800 rpm.

### Claim 4 (depends on 1)

The device in accordance with claim 1, wherein said electrical generator is provided with 100 poles/coils, thereby requiring a rotation speed of said first rotating shaft of at least one rpm.

### Claim 5 (depends on 1)

The device in accordance with claim 1, wherein said vehicle is moving along a circular track, and further wherein said electrical generator is surrounded by said circular track.

### Claim 6 (depends on 5)

The device in accordance with claim 5, wherein said vehicle is a locomotive.
