Participants will build a solar collector for the Learning Center’s gathering space using copper tubing and flashing, connected to an elevated hot water tank. This system--in which water circulates by gravity through the copper grid and directly heats the water tank--can be used during frost-free dates. A limited number of students may be able to build a system to bring home, at an additional cost. Please inquire if you are interested. Discount available as part of Sustainable Building series.
