Both here and in http://www.NicaLiving.com I keep seeing what I would call modern snake oil ads a lot more of the time than I like. They are not tonics and such but all too many have to do with Alternative Energy. And they are probably less useful than snake oil.
A lot of them are about a book or guide, delivered electronically that will allow you to cut your electricity bill in half for only a $200 investment or some similar scheme.
The site seeks to raise interest in and appreciation of wild lands and wildlife, while examining the impact of emerging trends in climate, technology, economics, and finance on conservation and development
Lots of really good "we did it like this" info on biogas, hot water and more. Warning: while it is supposed to be a blog, clicking the link downloads zillions of photo files and takes forever on an "ordinary" internet connection.
