David- I have not been able to get that study I told you about in a transmittable form for you. I know the California Solar Center did it, and I went to their site and could not locate the study, but I know it is there, somewhere. It is called The Potential for Solar Electric Generation in SF and it was done 6/1/01 for SF State Law School Environmental law and Justice Clinic, in case you want to look for it. I found another, more current url: http://sf.solarmap.org/ Which gives estimates for solar potential for any address entered in to it. Kinda neat, I would be interested to see what it says for your place, compared with other studies you have done. Mine says I could install up to 5 KW, produce over 9000 KWH/year and save up to $1500/year, now if I can only get the landlady to go for it.

Marx said it best in 1843: "Human emancipation wll only be complete when the real, individual man (sic) is absorbed into himself the abstract citizen; when as an individual man, in his every day life, in his work and in his relationships, he has become a species-being (politically accountabe to the whole); and when he recognizes and realizes his own power as social powers, so that he no longer separates this social power from himself as political power."
