## Abstract

A transport and power system having a plurality of tubes or tunnels, a magnetic levitation and linear motor train, and a superconducting power cable. One of the tubes can be an escape, power distribution, and maintenance tunnel. These tubes can be above ground, below ground, at ground, or under water.

## Claims

### Claim 1

A system comprising:
a tube infrastructure that includes one or more tubular structures disposed along a path;
a transport subsystem, disposed within the tube infrastructure, that includes a magnetic levitation mechanism for supporting and moving one or more magnetic levitation cars within at least one of the one or more tubular structures; and
an electric power distribution subsystem, disposed within the tube infrastructure, that distributes electrical power to locations along the path, and that also provides power to the transport subsystem's magnetic levitation mechanism, the electric power distribution subsystem including one or more electrical transmission lines;
wherein the tube infrastructure is shared between the transport subsystem and the electric power distribution subsystem,
wherein the one or more cars have an active seal system of seal structures disposed on the outside thereof such that each of the seal structures is not in contact with a wall of the tubular structure when an interior of the seal structure is at less than a local ambient air pressure, each of the seal structures is in contact with the wall of the tubular structure when the interior of the seal structure is at the local ambient air pressure, and each of the seal structures is in closer compliant contact with the wall of the tubular structure when the seal interior is above ambient air pressure.

### Claim 2 (depends on 1)

The system of claim 1 wherein:
the electric power distribution subsystem gives rise to associated magnetic fields; and
the associated magnetic fields electrical power are also used by the transport subsystem.

### Claim 3 (depends on 1)

The system of claim 1 wherein one or more train cars store energy in the form of kinetic energy.

### Claim 4 (depends on 1)

The system of claim 1 wherein:
one or more cars are provided with linear motors; and
at least some kinetic energy of a given car having a linear motor is returned to the electric power distribution subsystem as electrical energy in a process of regenerative braking using that car's linear motor.

### Claim 5 (depends on 1)

The system of claim 1 wherein one or more cars are operational in a closed tunnel or tube associated with the tube infrastructure.

### Claim 6 (depends on 1)

The system of claim 1 wherein:
the electrical transmission lines include one or more superconducting elements;
air is removed from one or more of the tubular structures to
obtain a low air pressure and reduce or eliminate air friction in connection with moving one or more cars,
improve the electrical isolation of electrically charged system elements, and
provide thermal isolation to maintain a constant temperature around the electrical transmission lines and any superconducting elements thereof.

### Claim 7 (depends on 1)

The system of claim 1 wherein:
air is reintroduced into one or more of the tubular structures from which air had been removed; and
the reintroduction of air into one or more of the tubular structures from which air had been removed can by itself cause one or more moving cars to come to a near complete stop.

### Claim 8 (depends on 1)

The system of claim 1 wherein:
one or more cars is provided with one or more passive sealing members; and
one or more of the passive sealing members cause the motion of the car to move and compress gas and/or air in the direction of the motion, and create a partial vacuum in the opposite direction.

### Claim 9 (depends on 1)

The system of claim 1 wherein:
one or more cars is provided with one or more active sealing members; and
one or more of the active sealing members cause the motion of the car to move and compress gas and/or air in the direction of the motion, and create a partial vacuum in the opposite direction.

The system of claim 1 wherein:
at least one car is provided with one or more active sealing members;
at least one car is provided with one or more passive sealing members; and
