This book provides the fundamentals of working with solar energy to the extent that you can build the projects included in the book. The projects range from simple science fair type projects to converting a home to run on solar electricity. This book follows the pattern of the other books in the series. There is a short section describing the theory of operation of each project followed by schematics, parts lists, and detailed instructions. All of the projects are the size of table-tops, but they can be enlarged to scale if needed.

The book begins by discussing the reasons to develop devices powered by solar energy. Economics and efficiency comparisons are made to standard energy sources. Among the projects discussed are two model solar water heating systems, a solar oven for cooking food, a basic solar water distiller, and a simple solar furnace. The solar furnace generates temperatures high enough that paper products can be ignited and low temperature metals can be liquified. Information is included on commercial solar furnaces. Next readers are shown how to build a simple thermoelectric generator that transforms heat into electricity. You are shown how to power the generator using the solar furnace from a previous chapter. Next readers are shown how to build a homemade photovoltaic cell using a copper sheet. Photovoltaic cells generate electricity directly from sunlight. This is followed by an advanced photovotaic cell construction project. Here you make a solar cell that uses photochemistry to mimic photosynthesis using photosensitive dyes that promise cheap solar electric power. The reader is taught how to build a solar engine, which is useful for tasks such as pumping water for storage and irrigation. Solar collector efficiency can be improved by tracking the sun, and to that end the author includes a simple electrical feedback system that tracks the sun across the sky. Also included are five or six smaller projects to more fully demonstrate the capabilities of solar energy. These include a rechargeable flashlight, special lights for illuminating a walkway, and simple solar cells. The following is the table of contents:

This book isn't by any means a textbook on solar engineering, but it is a great projects book to accompany the standard texts on the subject that almost never provide the kind of practical experience you can get by building the projects in this unique little book. If you want a good textbook to supplement this book of projects, I heartily recommend "Principles of Solar Engineering" by Goswami. That book has all of the mathematics and theory that really don't fit into this one. That text assumes little in the realm of mathematical maturity, but if you are lacking prior knowledge of thermodynamics, heat transfer, and thermal circuits, you might find yourself a bit lost.

I have been a solar electric and solar hot water installer for 3 years. I can design and install a system with ease and confidence, but the projects in this book increased my understanding to a whole new level. It was like learning about solar from the inside out. I always enjoy it when I can learn about something I know well from a different angle. Some of my friends bought the book for themselves after thumbing through my copy. I recommend this book for anyone who likes to have a hands on approach to solar in many different areas.

The author of this book was 19 years old when he published it. What an amazing 19 year old! He truly is a genius! My 15 year old daughter and I really enjoyed this book. One amazing project after another. Easy to understand instructions, easy to obtain materials--the author tells you how to order what you don't have--, and projects are easy to do. I especially liked the solar ice maker! I strongly recommend this book.

If this book included instructions on how to actually build the projects it discusses, it would be worth buying. As it is, there are only some vague guidelines and not-very-useful sketches. If you want to build any of these projects, you would in almost every case, be much better off using a search engine to find a page online that actually tells you how; It's free, and you're more likely to get detailed information.

The only reason I give this book more than 1 star is that there are at least a couple of projects that I haven't encountered online--so it seems to be at least somewhat original.

Though I must commend the author, who at 19 published this book, for his forward thinking and embrace of diy projects I found this book lacking.
As others have mentioned the projects are missing key details and can hardly be called projects. Most projects consist of one page or less detailing how the item is supposed to work and construction techniques.

Technical drawings consist of basic outlines and the photos printed in the book are of terrible resolution (remember the days of 1 megapixel cameras and vga dispaly? think that kind of quality)

The book seems meant to give a very cursory knowledge of solar energy and its uses; if you already have a basic idea of how solar panels work and what they can be used for I suggest you flip through this book at the library or bookstore before purchasing it. Many of the projects in the book are simply taken from other sources, most of them available free online, and though credit is given where it's due it can hardly be considered an original text.

100% a great book to check out of the library and return in 3 days once you have seen what it offers.

This book was a tremendous disappointment. The instructions are at best vague and are too general to be of much use to anybody. In many cases key information is simply missing. Much better sources are available for free on the web (and are also better written). There may indeed be 50 projects described in the book (if you count a "hot dog cooker", "a marshmallow melter","building a solar cooker" and "building a solar camping stove" a 4 separate projects) but really I think that is stretching things.

The only spark of "genius" shown here is that Mr. Gavin D.J. Harper was able to convince a publisher to actually print this manuscript. It throws into question McGraw Hill's reputation.

No more Gavin D.J. Harper for me.

[Note: the illustration of the title page shows "30 projects" while the cover of the book sent to me indicates "50 projects"]

Solar Energy Projects for the Evil Genius

This is a good book for a 10 year old maybe. Was expecting some neat, unconventional uses for solar energy based on the title, but this was just a collection of things such as distilling water with saran wrap and the like. Very disappointed.

I was disappointed in this book. It's hard to tell who the book is aimed at - an electronics buff or a middle school science teacher. There is almost enough information to complete many of the simpler projects, but not enough to tackle the more interesting ones. And some of the projects have no directions at all!

I would buy this book if I wanted to get inspired and play around with some simple projects, but if I were interested in constructing a photovoltaic system or a solar hot water heater, I would find another book. The book, Green Energy Projects for the Evil Genius, has more complete directions for more interesting solar projects that this book.

You can get the information in the book online for free..
* Black and white photos
* Phases of work you need further clarification
*Book gives an overview of the project .

This is a general overview of alternate energy products. Some items are speccific like how to build solar heaters and solar water heaters. I would have liked to see more specifics such as what fluid medium is recommended for the water heater and a bill of materials and tools required.
for all the projects.

Over all though this is a great book for a beginner. i liked it.
