Task: Sentiment Analysis
Input (English): Fluff book with no practical advice . This book uses a lot of buzz words and offers very little substantial advice when it comes to actually designing your own house.  It touches a little on straw bale and reused materials and barely grazes cob/clay/rammed earth.  It doesn't even mention geodesic domes as far as I can tell.  The book advocates on one page (p.72) that people should live in small humble buildings, only having the square footage they absolutely need.  Then a few pages later (p.79) it shows a 4000+ sq. ft. home, with the title "an excersize in efficiency."  I fail to see anything efficeint about a 4000 sq. ft. home, especially when it's a standard A-frame building (granted, it's for a family of 6, but then again there's nothing "green" about having 4 children).    It does cover some good stuff like gray-water use, rain collection, alternative heating and cooling, but it glosses over all of this and takes up a lot of space with strange-angled shots of rooms and floor plans.  I KNOW the floor plan I want, and there's very little that a floor plan has to do with green building (it's more about orientation to the sun for passive solar use).  What I'd prefer to have seen was simple diagrams of how the systems of the house work.  There's a spot that explains how one house has the pool hooked up to the AC such that the hot exhaust from the AC heats the pool.  Now THAT's something I can get into, but I want more than a couple sentences about it.  That deserves a diagram
