I talk about this stuff often in tiny house workshops, whether for The Tumbleweed Tiny House Company, or for the workshops and speaking engagements I've done on my own. In fact, July 6-9th at Tiny House Summer Camp, four days of tiny house learning, building, and well, doing, we'll most likely mess with a little bit of what you see in this video- solar cooking, and passively heating water for showers with the sun. Its a simple idea, and one that will enable you to cook, and shower, without using up heat-producing utilities in the summer- a time when you usually won't want your tiny, tiny house to become overheated.
After all, who wants to cook a 4 hour pot roast in an oven, in the summer, when your home is already too warm....herein, lies the avoiding solution.....
