[Greenbuilding] low flow shower heads

[lee Weaver]

 >>I am not preoccupied with costs in financial terms as much as in the 
materials and energy that are ground up in the process. Low entropy 
isn't something you can buy back with money.

This may be the statement that may "Shine a light"  for me.  Are there 
non sustainable materials used in purification?

I'm not worrying about the energy since i believe that we will soon 
solve the energy issues we have,  and finally break free of fossil fuel 
consumption.
