This video is made by a physicist who, before #911, was working on the same type of technology that was used to vaporize the twin towers.

It is fairly high level but also extremely in depth, worth watching for sure.

The video also explains how Richard Gage, the guy who came up with the "controlled demolition" narrative was a key player in the cover up of cold fusion in the late 1980's. So this Richard Gage covered up cold fusion after the famous experiments in the 1980's and covered up cold fusion as the cause of 9/11.
