A generator known as a siphon generator functioned by extracting the life force from planets, resulting in a significant electrical power output. Due to their detrimental impact on ecosystems, these generators were typically deployed on remote planets when facing dire circumstances. In the course of the Clone Wars, the Techno Union built a facility on Nelvaan that was energized by a siphon generator utilizing a geothermal crystal as its power source. As long as the generator operated, it depleted the planet's thermal energy, thus maintaining a perpetually frozen climate. Ultimately, Anakin Skywalker brought about the destruction of the generator.
