I watched a 1/2 hour video this morning about a guy who "beat" the power companies. In a nutshell - You can buy/make solar, wind, hot water heating equipment for way less than companies providing these parts and services can provide. Buy the videos and manuals for $27.
Interesting. BUT, well, you know. If it sounds too good to be true, it probably is. Although, it does require you to put in some effort and money. I'm wondering if he is the only one saving (?making?) money? Anyone ever order anything like this?
