This is one of those pages that I am completely rewriting in 2012 - a decade after the Solar Energy page on our free CDs. The efficiency of using solar power for creating electrical energy has improved perhaps several fold in the last decade. Unfortunately, solar panels operate only during daytime. On days that are cloudy, and in locations not near enough to the equator so that you get proper sun angles and that you have long nights, they are less efficient still. Consequently, for us in Canada, commercial solar panels presently have a payout of many decades, which means, given interest rates, the value of money, the life expectancy of the panels themselves, and human life expectancy - they just are not a practical way to go in most situations. They have application for some small off-grid power requirements in very remote locations but that is about it in many parts of the world. In outerspace with 24 hour sunlight they may be the cat's meow - but nothing that we need to concern ourselves about in a nuclear recovery situation.
After a nuclear war, solar power for making electricity is probably not going to be an option unless one happens to find some salvagable solar panels. I obtained books on the subject of making "hobbyist" solar panels. The panels are so terribly inefficient that it is just not a practical way to go at all. However, sunlight is a great power source for stills, solar cookers and as a means of heating water. Those are the applications that are treated here.
The focus of our website has greatly changed. Twice. First we were oriented towards telling people how to prepare to survive. How to build fallout shelters and so forth. Then we progressed to providing thousands of links to information about skills that would be needed in a Recovery stage. While remnants of these activities remain, our focus is now on the subject of Reconstruction of Society after nuclear WW3 or some other destruction of on a similar scale.
