Vice President

Hans grew up on Pewaukee Lake, and after a period away, for school and work, returned and has now resided on the lake for 40 years. He also spent 22 years living on Eagle Springs Lake in southern Waukesha County. A life-long sailor, he has competed in numerous one-design and ocean racing classes in the US and Europe in addition to cruising in the Atlantic, the Pacific, the Caribbean and the Mediterranean. He was twice designated All American while sailing for the University of Michigan and was one of eight selected for the US Intercollegiate Team to represent the US in a 27-match series held in the United Kingdom. Hans graduated from the University of Michigan with a bachelor’s degree in aeronautical engineering and immediately out of school began working in collaboration with Buckminster Fuller, perhaps best known for his geodesic domes. One of Fuller’s principal tenants was that mankind needed to learn to live off its ‘income’ energy, the sun, not its ‘savings account’ energy, fossil fuels. While this was far from mainstream thinking in the 1970s and 1980s, time has added perspective. This collaboration led to the formation of a company dedicated to building wind energy systems, solar electric systems, and battery energy storage systems along with the power electronics equipment necessary to interconnect these systems to the utility grid. Today that company exists as the Power Electronics Division of S&C Electric. Later, Hans started and operated a 70 acre ‘choose and cut’ Christmas tree farm in Eagle, Wisconsin….a ‘happy’ side-line business. In the early 2000s he purchased an amphibious seaplane and earned his land and sea pilot certificates. Over the years Hans has served on the boards of the Solar Electric Industry Association, The Buckminster Fuller Institute, the Eagle Spring Lake Sanitary District and the Pewaukee Yacht Club.

Secretary

Scott is a lifelong Wisconsin resident, who had the privilege of growing up on Big Cedar Lake in Washington County. As such, he has been active in fishing, scuba diving, snorkeling and underwater photography on the lake for many decades. It was in the summer of 2021 that Scott noticed significant changes to the deep weed beds on the South End of Big Cedar, namely their disappearance. A friend mentioned to him a study North Lake did, that highlighted the potential of enhanced wake boat waves disrupting underwater vegetation in water as deep as 17 feet. That began his journey to compare his extensive underwater photography from a decade ago, with the same areas in 2022 and 2023. He is a Wisconsin resident with strong private sector work experience and a graduate of the University of Wisconsin Law School.
