Advanced power generation unit reverse-engineered from alien technology, and widely used by Stargate Command and the Atlantis expedition (and related Earth research). The generator is powered by a small amount of the mineral naquadah, and runs cleanly with a significant output of energy.
A single generator can be used to power a Stargate without a D.H.D. for manual dial-out, and has also been adapted to power many other devices (often of alien origin) -- including the modified virtual reality unit and Merlin's phase device. A smaller version of the unit has been adapted to power a hand-held rifle weapon, the X-699 plasma cannon. The technology has been heavily relied upon by the Atlantis expedition to supplement the Z.P.M. power systems of the Ancient city in the distant Pegasus Galaxy.
A naquadah generator can also be set to overload, resulting in a sizable explosion.
Learning Curve - Earth's prototype naquadah reactor is developed when the Orbanians share the technology with Stargate Command.
Lifeboat - Carter brings a naquadah generator to P2A-347 to recharge the power systems of the Stromos and revive the individuals sleeping Talthuns within.
Space Race - The S.G.C. loans Warrick a small-scale naquadah reactor to power his ship, the Seberus, in the 59th Loop of Kon Garat. Carter accompanies the device to participate in the race.
Lost City, Part 2 - O'Neill requires a small naquadah generator to modify the rings on a Tel'tak bound for Proclarush. He eventually the uses device he builds to drill a hole in the ice of Antarctica, gaining access to the Ancient outpost of Atlantus.
Rising, Part 1 - The Atlantis expedition brings naquadah generators to the Pegasus Galaxy, where they are used to power the lost city of the Ancients -- though they can't come close to matching the power output of Zero Point Modules.
Critical Mass - Auxiliary naquadah generators are reactivated to augment the power supply in Atlantis when the Z.P.M. is disconnected.
Ethon - Carter and Captain Marks attempt to rig a naquadah reactor to augment the damaged Prometheus's sub-light drive, but the ship is destroyed before they can implement their work.
Line In the Sand - Sam uses a naquadah generator to power Merlin's phase technology, putting her and Mitchell out of phase when the Ori invade a village.
The Road Not Taken - While experimenting further with the generator-powered phase technology, Sam is pulled into a parallel reality.
