Tribophysical waveform macro-kinetic extrapolator

The Tribophysical waveform macro-kinetic extrapolator utilises mass amounts of energy and then wraps the user in a protective bubble allowing them to ride the shockwave of power away to safety. Blon Slitheen intended to do this to escape early 21st century Cardiff. (DW: Boom Town)

It was subsequently utilised by the Doctor and Captain Jack Harkness to create a force field around the TARDIS by utilising the energy from the Daleks' missiles. Following that use, it was used to protect the upper floors of the Gamestation from the Daleks' transmats. (DW: The Parting of the Ways)

When the Doctor used it to move the TARDIS 200 feet away from the Racnoss it appeared to have been morphed into the TARDIS systems almost growing itself into its systems. (DW: The Runaway Bride)
