I found this very useful website, I was searching the net for a very long time for something similar. A lot of good documentaries are here and with very good quality, mostly about 9/11 but skip to the end of the page and you'll find a lot of even more interesting documentaries.
Make sure you check the one on "Zero Point Energy" which is what I was looking for in the first place... I first knew about this a little more than two months ago and it is still mind boggling to me.
