This video is about 9 1/2 minutes long and, unfortunately, includes commercial interruptions.  It is a quick overview of at least some of the competitors of Tesla in the energy storage market and it also has some mention regarding solar cell and solar roof competitors as well.  It goes pretty fast and there isn't much in way of dead space of "fluff".  I think he gives an overall slant to Tesla, but I wouldn't say he is slamming the competition either.
