There are many ways to get energy for free,after the intial investment. Solar,wind and hydroelectric are just a few ways.Here is a website where you can buy turned key systems or do it yourself kits,books and components. www.magnet4less.com Also they have water softener magnetic systems. These you can purchase from them or I will tell you how to build your own. Take two large long ceramic magnets,one on each side of water pipe,put in the attraction mode,turn north ends toward you water outlet(spigot),then tape or tie onto pipe. It will break down minerals in your water and and make it softer. Softer water requires less detergent for dishwashing,washing machine and taking a shower-bath. It not only will save you money on cleaners but also the water will taste better and be better for your body. Also when it breaks down the lime,which is a problem in some areas,it will keep your water pipes and heater from accumulating deposits in them. Your entire system will work better.
