This device produces many gallons of distilled water a day while it charges batteries, makes domestic hot water and heats space. Distilling spirits and food cooking are additional functions for this system. It employs an ordinary household pressure cooker or a small water tube boiler on a low simmering fire. Its closed-loop system recycles the exhaust heat and maintains the water level in the boiler for high efficiency. This model steam engine operates the system on 2.5 to 30 psi of steam pressure. The system is scalable for larger requirements. License is available... The boiler plans are for a safe water-tube boiler that may be used with a variety of fuels such as gas, wood, pellets, or other bio-fuels. The boiler in the plans is easy to construct with readily available materials. The plans include the boiler feed pump that recycles the water for efficient and economical operation. The boiler may be scaled for large or small engines.
