Furthermore, in addition to carbon-free power, one of the benefits was supposed to be flood control, but we are now seeing that … More Small-Scale Hydropower?
Last year I built prototype solar panels and summarized the preliminary data gathered in some test runs (see this project’s archive here). Yesterday I provided the plans and schematics for this build. Today I’m going into some of the nitty gritty installation details. Burying the Supply and Return Lines The supply lines are buried 2 … More Installing Solar Hot Water Panels, Part 2 — Lab Note 1.07
Last year I built prototype solar panels and summarized the preliminary data gathered in some test runs (see this project’s archive here). Here I will outline the plans drawn up to get a building permit from our local municipality. Schematic Plans These show the basic operation of the system. It is a schematic and not … More Installing Solar Hot Water Panels, Part 1 — Lab Note 1.06
