Z4 Energy Systems, LLC (Z4), was founded in 2004.
The company focuses on developing reliable renewable energy products for individuals, small business, and agricultural consumers. In 2008, Z4 received SBIR funding through the National Science Foundation and U.S. Department of Agriculture to develop a self-adapting rotor blade for small wind turbines, a wind-powered water pumping system featuring compressed air energy storage, and a 100% solar-powered livestock watering tank de-icing system.
The company is currently in Phase II development on the Rotar Blade and Wind-Powered Water-Well Pumping projects. In 2012, Z4 plans to have field-tested prototypes for each.
