Vortex energy

Vortex energy, also rendered as Vortex Energy, was dangerous, "unrefined" temporal energy from the Time Vortex. 
It flowed through the Heart of the TARDIS, (TV: The Halloween Apocalypse) but it was dangerous to try and power the TARDIS directly with vortex energy, which could cause power surges in the TARDIS control console. (GAME: Lost in Time)
The Tenth Doctor found traces of vortex energy in Heather McCrimmon's DNA. (COMIC: The Chromosome Connection)
When Rose Tyler attempted to get the TARDIS to start to reunite her with the Ninth Doctor on the Satellite Five in the year 200.100, she forced open the Heart of the TARDIS from the TARDIS console, which caused Vortex energy to flow into her via her eyes, which gained a golden glow to them, and created the Bad Wolf, which destroyed all the Daleks that were present and revived Jack Harkness. The Doctor then noted it would kill Rose and was forced to sacrifice himself by absorbing all the energy into himself, and released it back into the TARDIS. (TV: Bad Wolf)
The Slitheen Blon Fel-Fotch Passameer-Day Slitheen, disguised as Margaret Blaine, was forced to look into the Heart of the TARDIS, into the Vortex energy, and as a result was relieved and regressed into an egg. (TV: Boom Town)
When the Flux was approaching the TARDIS, the Thirteenth Doctor unleashed vortex energy from the TARDIS console at it, however the energy appeared to have no effect. (TV: The Halloween Apocalypse) The collision between the energy and the Flux caused the TARDIS and its occupants to fall through time, intially sending them all to the Crimea in 1855 and subsequently sending Yaz to the planet Time and Dan to Liverpool in 2021. (TV: War of the Sontarans)
Space-time Waypoints were points in time and space that became supercharged with vortex energy. During a temporal crisis which grounded TARDISes and similar machines throughout the universe, the Doctors realised they could only travel from one Waypoint to the next, draining each of vortex energy to temporarily, messily re-power their TARDIS before depleting their reserves with the next hop. 
These Waypoints included UNIT HQ, which became charged with vortex energy due to "almost passing through the event horizon of a black hole" (GAME: Lost in Time) when Omega transported it to his anti-matter universe, (TV: The Three Doctors) Atlantis (frozen in its final moments in a time eddy) because of the Crystal of Kronos, the Dalek City on Skaro at a early point in its history that future Daleks had visited, the Panopticon on Gallifrey, the place in Nevada where Clara Oswald parted ways with the Twelfth Doctor, the Underhenge right before the Eleventh Doctor was placed in the Pandorica, and the Minyan spaceship.
