In 1997, Robert and his wife built a passive solar home in Santa Cruz County and outfitted it with an off-grid solar photovoltaic system. He has been living with solar energy since then, always looking for new ways to apply solar in his daily life. He drives a solar-charged Plug-in Prius, heats his water with a solar water heating system, and bakes his bread in his solar oven. He has served as host to hundreds of people who have toured his home to see his solar exploits firsthand.
