From the site:
Development of the Azura technology is a collaborative effort between NWEI, Callaghan Innovation, and Energy Hydraulics Ltd (EHL). Callaghan Innovation led the conceptualization and early development of the technology in New Zealand, and NWEI recently secured a global exclusive technology license from Callaghan Innovation to commercialize the Azura technology. EHL plays a critical role in advancing the technology and is responsible for the engineering, fabrication, and testing of the power conversion system.
I have seen this device "in person" and it is pretty cool. As it was built a few minutes from where I live in New Plymouth, NZ.
