We are a manufacturing company located in the middle of the US heartland in the Greater Chicagoland Region.  We're a renewable energy company, developing products at the water/energy nexus. Our products are meant to make people's lives better, to promote independence, and to make people richer. From refrigerators that use little to no electricity, to water purification solutions that can work in every home, to heaters that use heat from the environment to drive their heating, we are developing technology that will reduce costs, improve resilience, and protect our environment.
