Stephen Chastain has just completed his latest project, a combined heat and power plant! Most generators are only about 25% efficient, making them too expensive to operate on more than an emergency basis. Steve’s home-made generator set with an inverter system, powers the house plus provides heat and hot water for about 70% efficiency! If you wanted to move out to the woods but didn’t want to give up your air conditioner and satellite, now you can! Order the new generators and invertors book now and start building power!
