A spherical assembly for vehicle propulsion comprising:
- a propelled vehicle frame;
- a stationary solid spherical outer enclosure connected at its top pole to the propelled vehicle frame by pivoted connection allowing its movement around its vertical centerline through springs and shock absorbers and partially concentrically encasing;
- a sealed spherical inner assembly touching the ground and allowed to rotate around a fixed stationary centerline connected to the stationary outer enclosure and comprising:
- a first electric motor connected to a first unbalancing weight and to the spherical inner assembly;
- a second electric motor connected to a second unbalancing weight and to the spherical inner assembly;
- a third electric motor connected to a third unbalancing weight and to the spherical inner assembly;
- and
- a fourth electric motor connected to a fourth unbalancing weight and to the spherical inner assembly, wherein said first weight, the second weight, the third weight and the fourth weight are equal in weight, and their centers of gravity rotate at equal radii;
- and a controller in the propelled vehicle, operatively coupled to the first motor, the second motor, the third motor, and the fourth motor, and configured to:
- cause the first motor to rotate the first weight in a first direction at a first rotational speed based on a rotational speed of the spherical inner assembly;
- cause the second motor to rotate the second weight in the first direction at the first rotational speed;
- cause the third motor to rotate the third weight in a second direction at a second rotational speed based on a rotational speed of the spherical inner assembly;
- cause the fourth motor to rotate the fourth weight in the second direction at the second rotational speed;
- cause the first and second rotational speeds to be the rotational speed of the inner assembly wherein all the weights are configured and arranged such that their centers of gravity remain in only the forward one half of the spherical inner assembly in spite of its rotation;
- cause the first motor and the second motor to rotate the first weight and the second weight such that the first weight and the second weight simultaneously provide a greatest moment of gravitational force to a point along the fixed center line of rotation of the spherical inner assembly simultaneous to when the controller causes the third motor and the fourth motor to rotate the third weight and the fourth weight to simultaneously provide a greatest moment of gravitational force to a point along the fixed center line of rotation of the spherical inner assembly causing it to rotate at the maximum speed of rotation that the gravitational forces, acting upon the weights, can provide.
