Hi All, I'm a 67 year old Designer. I build prototypes for energy and environmental projects. The last project resulted in a quarter million gallon anaerobic digester. Currently I'm involved in hydrogen generators and thermal optics. But I need less good guesses and more definitive science! Check out www.terradesic.com I spend my fun time surfing in the Eastern U.S. and Central America. Looking forward to joining the group here!!
