GN Drive Tau

GN Drive Tau are known as false solar reactors (疑似太陽炉, Giji-Taiyou-Ro?) and/or false solar furnaces, generally known as GN Drive [T]. GN Drive Taus are poor imitations to real GN Drives and incapable of semi-perpetual energy generation or storage because they lack TD Blankets, a component relevant to GN particle generation and utilization. The GN particle energies that derive from such drives disperse orange-reddish hues and have toxic effects upon human exposure.

The technical designs is believed to be originated from Ribbons Almark, who in turn sent them to Linear Train Industries for Laguna Harvey. Laguna Harvey used the designs to develop the Throne Gundams and later the GN-X's for the UN Forces. After the formation of the Earth Sphere Federation, the technology already has been mass-produced in great numbers to the Federation Army and A-Laws.

GN Tau Particles
Just as the GN Tau Drive used by the Gundam Thrones and GN-X models is an imperfect version of the true GN Drive, so are the GN Tau Particles imperfect versions of the true GN Particles. Generated by GN Tau Drives, they share most properties with GN Particles (including radio disruption, use in beam weaponry and propellant applications), but do not allow for enhancement of quantum brainwaves. More viciously, GN Tau Particles can cause cellular damage, which cannot be repaired through 24th-century medical science. Louise Halevy's inability to regenerate her hand was caused by exposure to GN Tau Particles from Nena Trinity and her GNW-003 Gundam Throne Drei, and it is possible that her current health conditions also stem from the cellular damage caused by the attack.

GN Tau Particles are a blood-red color, which can change to a bright orange when multiple GN Tau Drives are used at once.
