The Hypercoil is a DEW (Directed-Energy Weapon) that is able to generate approximately 1.21 gigawatts of electric current and channel it into a beam of pure electricity. It was invented by Nikola Tesla, and was used by Will Grey to electrically restart The Ark's engines by charging up the propulsion generators on the side of The Ark; the engines had failed because these generators had caught on fire and thus were not working correctly.

It is able to overcharge Watcher vessels with electricity, such as Watcher Flying Discs and Archons (only on the Archons weak points, though). After enough overcharging, the weapon causes these vehicles to explode.
