"The day spent at the Akron Zoo workshop was outstanding! Like most adults 50 years old, I have endured too many soul draining seminars and workshops in search of knowledge and enlightenment. Your workshop was awesome! The combination of "tech speak" combined with man on the street explanation was a perfect fit for me. Thank you for an informative, entertaining and valuable workshop."

Stewart Brand wrote "We are as gods and me might as well get good at it" in the first Whole Earth Catalog. Well Jay is good at it. He has interpreted the technical, governmental and human nature involved in designing solar voltaic systems to be understandable. The first day really sucked me in with Jay's views of the energy business and reinforced my thoughts on the topic. His teaching method was spot on with this complicated subject. Jay broke each section down so it could be understood. He would often digress into some humorous stories that often had me laughing. Solar technology is changing rapidly and Jay gave us many ways to keep up with it. The price of the class will be paid back many times over the next few years.

Thanks again for the course last summer. Looking back its hard to believe its been a year since Yellow Springs. The course really was like drinking out of a fire hose and at times I wondered what I had gotten myself into. I honestly didn't think I had passed the test. Yet year later I here I am. Hell, I've only been in this new position for a few months and I've made lead site surveyor of the team.
