We’re a team of Australian Engineers who love building efficient technology that delivers proven return on investment. Our proprietary Diffuser technology was invented by our Founder Dr Joss Kesby and leverages over 20 years of international peer-reviewed research. It is through this technology that we are able to develop the safest and most powerful small wind turbines on the market.
Diffuse Energy was founded in 2018 with the aim to commercialise new small wind technology that allows Australian people and businesses to harness the wind's never ending energy supply and produce their own energy. Our small wind turbines can be used in unison with existing technologies like solar PV and battery storage to achieve 100% renewable power solutions. Now that is what a cleaner future looks like.
A natural born leader and project manager; Dr Joss Kesby is the inventor of Diffuse Energy's high-efficiency wind turbine technology. His entrepreneurial capacity has been recognised in being awarded the 2018 CSIRO Stanford Australia Scholarship. In 2019 Joss received his PhD in Mechanical Engineering - specialising in wind energy from the University of Newcastle, Australia.
In his spare time, Joss enjoys playing tennis and watching kids movies with his two boys. Joss has always had a passion for wind and was an avid hang-glider in his younger days. Helping improve the environment so his kids can enjoy nature is what drives Joss to succeed with Diffuse Energy.
James has extensive experience in both engineering and business operations. James is at home leading the engineering design and product manufacture of our wind turbine technology. Prior to his time at Diffuse Energy, he had over a decade working in a variety of retail businesses, mining consulting, and engineering workshop management.
James’ three favourite things are family, the ocean, and building all manner of things… some would say he’s the DIY king. In James’ words - “Being part of solving our energy problems is pretty exciting. I've always loved being outdoors in nature so I enjoy playing my part in preserving it. Designing and building cutting edge technology is really hard, but super rewarding”.
Our proprietary diffuser technology maximises airflow through the turbine blades to unlock incredible efficiency gains. It's a system operating in perfect harmony.
The Hyland 920 wind turbine system includes a Diffuse Energy maximum power point tracking (MPPT) controller that optimises the amount of power extracted for a given wind speed. For wind speeds beyond 18 m/s (65 kmh) the controller is designed to reduce the rotor speed to limit the power output to 1 kW and prevent the damage of electrical systems.
Noise output of modern small wind technology is low. When assessing noise levels of existing wind turbines certified by the Small Wind Certification Council (SWCC) average noise levels are reported at 45 dB(A) for an open-blade horizontal-axis design. Noise of this level is deemed within the range of “quiet radio music” by Safe Work Australia.
The Hyland leverages over 20 years of research and development at the University of Newcastle, Australia. Mechanical components have been designed in accordance with international small wind turbine design standard IEC 61400.2-2013. State-of-the-art computer aided engineering software has been used to verify the wind turbine components. Wind loading has been calculated as per AS1170.2 for Category D wind speed with a return rate of 50 years. Composites used in construction have a minimum rated UV exposure life of 20 years.
Studies have shown that there is little evidence that wind turbines pose a significant danger to birds or bats. Diffuse Energy’s novel wind turbine technology may assist wildlife in avoiding wind turbines. Our rotor is enclosed by an aerodynamic shroud which by design, prevents exposure to the blade tips. Also, the higher rotational speed of small wind turbines is a larger deterrent for animal interaction.
