Gas consumption

what i am interested in is the full cost of making and back to original eliments do compact florescents really save the enviroment as they are being touted as. i do use them and try to recycle them as well as regular light bulbs, and most of the other product that we can.

here is a question for all of you does any body know of a bear proof compost bin or system? now that we have ower own house we would like to have a garden and use the composted kitchen scraps. but the bears will get in it and i don't think that our new neighboures would be all that impressed with use for that.

as for the acetone i'm not sure but if it will dry out the rubber what about using methal alcohol?
