How To Power Everything From The Sun

Are you a self reliant do it yourself-er in most areas of your life? Do you care about the well being of the environment and do you have an interest in sustainable energy? If you answered ‘yes’ to the above questions, this book called, “DIY Solar Power: How to Power Everything from the Sun” could be precisely for you. We like this book because it promotes the concept of self reliance combined with solar power. In this book, you’ll find the basics of how solar power works, a detailed explanation of the components used in solar power, the different types of solar power systems from mobile to large scale solar installations, grid tied and off grid systems and it concludes with examples of solar power projects. Here is an excerpt from the book:

The practice of using mirrors to reflect and concentrate the sun’s energy isn’t just applicable on large scale projects like massive heating towers. You can collect solar energy at home too, and without needing to generate any electricity! Many people all over the world use solar ovens to cook food. By using the same concept of redirecting and concentrating the sun’s energy, people can boil water or heat food with the power of the sun instead of burning wood or charcoal. This also helps by reducing pollution from thousands of cooking fires, as well as decreasing deforestation in many sensitive areas of the world.

Solar cookers and ovens come in many different varieties. A common solar cooker setup uses a curved mirror that looks like a satellite dish. A pot is placed in the center and the entire apparatus is pointed at the sun. The sun’s rays are reflected off of the interior of the dish and concentrated on the pot in the center, heating it to cook food or boil water.

Solar ovens are usually boxier, but have a wide top with reflective panels that collect sunlight and bounce it into the box. A glass top helps keep the heat in, creating a greenhouse effect. Reflective walls inside the box ensure that light reflects until it hits the food in the center of the box, cooking it similarly to a conventional oven.

Other uses of solar energy for heating include passive solar water heaters. Israel, a country with limited traditional energy resources but an abundance of sun, has one of the highest rates of solar powered water heaters in the world. After experiencing a significant nationwide energy shortage in the 1950’s and 60’s, many people turned to passive solar water heating to provide hot water for their homes. This worked so well that the Israeli government eventually passed a law making it mandatory to install passive solar water heaters on all residential buildings, a decision that has saved hundreds of millions of dollars ever since.

Solar water heaters are simple devices that require no electricity at all, and can be used effectively in many parts of the world. Municipal water flows up to a tank on the roof of a home, where it then flows through a series of pipes, usually painted black, which are angled towards the sun. The intense heat of the sun quickly heats the water in the pipes, which becomes less dense as it gets hotter. The hot water then reaches the tops of the pipes and flows into the storage tank. When it’s time for a shower, the hot water on the roof is supplied and the homeowner gets a nice, hot shower without the need for any electricity.
