The strange thing about the bug is that it wasn’t directly powered. It was actually a resonant cavity that only worked when it was irradiated with an external RF energy. Most of the video is background about the bug, with quite a few details revealed.

The video at the link below has a lot of background of how it came about, as well the recreation exercise for the BBC. But the article also contains some links out to further sources on the reasons why the bug actually works.
