The locomotive carries a small portable nuclear reactor that heats a fluid to boiling, and passes it through electric turbine engines to produce electric power. The fluid/steam then recirculates through cooling radiators condensing it back to liquid before it passes back into the reactors again. The electric power is used to power and cool the onboard electromagnets, which oppose passive permanent magnets or magnetic coils in the roadbed. The onboard reactor is capable of providing greater electrical power than previously described maglev systems. This, in turn, provides greater power to the superconducting electromagnets, which translates into greater lift capacity and greater speed. | 11-19-2009 |
| 20090165667 | Apparatus and method for electromagnetic levitation on an uncharged and non-magnetized arbitrary surface - Methods and systems for levitation on uncharged and non-magnetized arbitrary surface are disclosed. The system comprises a stack of conducting power plates, a high frequency high voltage (HFHV) source, a force feedback step-up transformer (FFST) and an uncharged and non-magnetized arbitrary surface. The secondary coils of the FFST charge a stack of conducting power plates. The charged conducting power plates switch its polarity in a controlled manner. Due to kinetic inertia of the effective dipole moment of the uncharged and non-magnetized arbitrary surface, the dipole moment cannot maintain the changes in response to the changes in polarity of the stack of conducting power plates and thus, a repulsive force is generated between the stack of conductive power plates and the non-magnetized arbitrary surface. The controlled repulsive force initiates and maintains the desired level of levitation with respect to the uncharged and non-magnetized arbitrary surface. | 07-02-2009 |

| 20110061560 | Apparatus and method for using electric fields to cause levitation on an uncharged and non-magnetized arbitrary surface - Methods and systems for levitation on uncharged and non-magnetized arbitrary surface are disclosed. The levitation system generates electric fields in order to cause dielectric polarization on the surface on which levitation is to be caused. Methods and systems are disclosed in which the polarity of the electric field that is produced by the system is switched in a controlled manner. Due to kinetic inertia of the effective dipole moment of the uncharged and non-magnetized arbitrary surface, the dipole moment cannot maintain the changes in response to the changes in polarity of the electric field that is produced by the levitation system and thus, a repulsive force is generated between the levitation system and the non-magnetized arbitrary surface. The controlled repulsive force initiates and maintains the desired level of levitation with respect to the uncharged and non-magnetized arbitrary surface. Additionally the source of electric fields is made to have a large area in order to increase the repulsive force on the levitation system. | 03-17-2011 |
| 20090320713 | People & Cargo Transit Systems & Vehicles - The Application discloses People & Cargo Transit Systems & Vehicles (PCTSV), using Narrow Vehicles (NV), which can have the form of a Bus, Train, Tram, Maglev, Mono-Rail or even Car or Truck. A preferred version of which is Single Seat Wide or below 70 cm wide, preferably a Bus type to need no Rail, using Dedicated Narrow Lanes adjacent to Curbside of existing intra-city streets or limits of inter-city roads. Said NV and Lane have Anti-Roll Over Means to stabilize such a narrow vehicle, which also eliminate NV Swaying even when NV is a Bus or Car with has no inherent Sway Limiting. Being Ultra Narrow with No Sway and Running at Curbside results in Negligible or No Blocking of other vehicles by NV.Said Lane/Tack, Anti-Sway & Anti-Roll Structures all Allow being Run Over by other Traffic and have structures not to be damaged, thus can be crossed over at Crossroads and other entrances and exits along said Lane. NV has enough Doors and is Narrow, hence each Passenger can reach a seat or exit, with No Isle inside it to walk along. So it can have Low Profile, like a Sports Car, some 120 cm tall. Hence it is easy to have Covered Trenches at cross roads for non-stop crossing. Trenches can run along most or all the Track, in which case adherence to streets and roads is relieved. Such Narrow and Shallow Trenches take a tiny fraction of time and costs of Skyways or Subways. Each Passenger thus can have her own door, own seat, in a small Cabin, which can be opened and closed to next Cabin, have reclining seats to join to that of next Cabin to sleep on, have laptop tray, etc. All those make PCTSV much more appealing to user's, even better than private transport. There are many Variations other than above. There is an NV Car for the last mile and or long distance use, which can integrate with NV Public Transit. Also modifications to NVs for use in Cargo and Parcel Transit. | 12-31-2009 |

A stator current is supplied to the stator to produce a propulsion force on the maglev track, the propulsion force acts upon the maglev car being determined by the magnetic coupling between the magnetic stator field and the magnetic levitation field. An oscillating movement of the maglev car in relation to the magnetic stator field is dampened by changing the magnetic coupling between the magnetic stator field and the magnetic levitation field on the car side. The levitation magnets are operated on the car side with at least two different individual levitation magnetic fluxes. | 05-27-2010 |

| 20100064929 | INDUCTRACK III CONFIGURATION - A MAGLEV SYSTEM FOR HIGH LOADS - Inductrack III configurations are suited for use in transporting heavy freight loads. Inductrack III addresses a problem associated with the cantilevered track of the Inductrack II configuration. The use of a cantilevered track could present mechanical design problems in attempting to achieve a strong enough track system such that it would be capable of supporting very heavy loads. In Inductrack III, the levitating portion of the track can be supported uniformly from below, as the levitating Halbach array used on the moving vehicle is a single-sided one, thus does not require the cantilevered track as employed in Inductrack II. | 03-18-2010 |
