Z4 solves problems for rural homes, farms, ranches and small business by developing useful, smart residential scale renewable energy products.

Z4 is developing three products funded by grants from the National Science Foundation, U.S. Department of Agriculture and State of Wyoming SBIR/STTR Initiative (WSSI) Small Business Innovation Research (SBIR) program.

  • Rotor blades for horizontal-axis residential scale wind turbines that self-adapt to varying wind conditions. The blades bend and twist along their length through a prescribed combination of blade shape and composite material properties to produce progressive feathering as wind speed increases.
  • Off-grid water well pumping system uses wind power to produce compressed air that powers the well pump and stores air for pumping water during times with no wind.
  • Solar powered heater for deicing livestock watering tanks. The heater melts ice that forms overnight and maintains a 2-foot diameter opening during the daytime when livestock normally drink.
