Thermal Discouragement Beam

The Thermal Discouragement Beam is a technology used in the Aperture Science Enrichment Center several centuries after Portal, and slated to appear in Portal 2.

Overview

 * The Thermal Discouragement Beam, created from at least 1998, aims at "discouraging" threats such as Sentry Turrets, thus burning / destroying them with a laser. The beam can be redirected using Weighted Pivot Cubes into awaiting receptacles.


 * "Thermal Discouragement" is a registered trademark of Aperture Science.

Behind the scenes
The Thermal Discouragement Beam was first introduced during the Portal ARG, in one of the ASCII art images given by the BBS, that later appeared to be a diagram depicting its use with a Weighted Pivot Cube, as revealed by the April, 2010 issue of Game Informer. An updated and moving diagram was revealed during E3 2010.
