The recycling shower: If NASA can do it, why can't we?

At the turn of the last century I became concerned enough about the so-called impending "water wars" that I started to experiment with ways of recycling my shower water.

A number of years ago I implemented a refinement of the ideas I tried in Los Angeles California (where drought is an ever present threat)at the L.A. Ecovillage in 2000 through 2003, in Sonoma County in 2005 with Frank DiMassa Utility Consulting, and in my home in Germany from 2008 (where water costs about 3 Euros a cubic meter, one of the most expensive water costs in the developed world.)

Dispelling myths surrounding the domestic dragon

1.  Does biogas pose a climate change hazard? Isn't biogas methane, the same gas that is 25 times more potent a greenhouse gas than carbon dioxide?

2.  Does biogas scale up? Can we use waste water treatment facilities to treat our food wastes?  If so, why wouldn't that be better than trying to do this at the home or community scale.

3. Could biogas be generated IN the kitchen, under the sink for example? Could it be incorporated into new kitchen designs?
