Las Vegas team develops tech to harvest water from desert air

WAVR secured $4 million in funding to scale hydrogel membrane technology that absorbs water from desert air, inspired by tree frogs, addressing severe water scarcity issues.

  • WAVR, a startup launched in 2024 inside a UNLV lab in Las Vegas, develops technology to harvest drinking water from desert air using a hydrogel membrane.
  • The company formed because Las Vegas faces water scarcity, with insufficient river and aquifer sources to sustain its growth and community needs.
  • The researchers developed a highly water-absorbent hydrogel membrane to effectively capture moisture from the air, drawing ideas from the natural ability of tree frogs to take in water from their environment.
  • After three years of development, CTO Yiwei Gao stated that the team had created an initial working prototype of their technology, and they secured $4 million in seed funding.
  • WAVR plans to use funding to scale pilot projects producing hundreds to thousands of gallons daily, advance R&D, develop production designs, and expand patent portfolios.
