Greatly updated second version! Four of the original topics greatly expanded with images and information, how-to info, details and Q&A's, and more. The non-electric solar topics include: 1) how to make a solar oven, 2) how to design a solar water distiller, 3) how to design a passive solar house, and 4) how to make air conditioning earth tubes. These topics are built on each other in concept, going from easier to harder, with the exception of earthtubes, which are supplementary to passive solar house design and involves passive cooling rather than passive heating (the latter of which is done through the design of the house itself). These four subjects are also great for people who live off grid or plan to live where there is sunshine but want to reduce their power bills. There is no reason why utility bills have to be outrageous when the design of your building projects can utilize renewable energy to bring you purified water, hot cooked food, warmth during winter, and a way to keep cool in summer. I have personally built all of these projects and you can too. Everything I can think of is covered here on how to do it.
