Um, the reason algae is a good solution is that it can grow just fine in salt water, it does not require potable water like ethanol and normal BD are.
you fail to realize that you can make potable water from saltwater or greywater. i dont know if you are educated about things such as osmosis or distilation but that pretty much solves the clean water problem. The internet is not always a really good place to find reliable information. I you go to any professor at a better school and say your going to use the internet for source information their going to laugh you out of the room.
You should inform China about that, they are panicking about their water situation, apparantly its just that simple.
The truth is that greywater is simply water recycling, and it only works to a point(and has nothing to do with wasting water on farms), and saltwater is NOT easily desalinated, the process is energy, space and time intensive, its not suitable for large scale water production. We are coming up on a water crisis, even in the US, and that has nothing to do with 'internet sources', plenty of respectable scientific magazines are publishing articles about this on a regular basis now.

But then I suppose you might not want to get 'laughed out of the room' by your college professor...
