    EP183 Reinventing Wind Power: Inside the World of Harmony Turbines (August 2024)

    In this episode of the Building HVAC Science Podcast, hosts Eric Kaiser and Bill Spohn are joined by Chris and Cheryl Moore, the founders of Harmony Turbines, to discuss their innovative approach to wind energy. Chris and Cheryl share the origin story of Harmony Turbines, which started as a personal project in Chris’s basement, driven by his desire to create a quieter, more efficient wind turbine that could operate in lower wind conditions compared to traditional propeller turbines. They explain the challenges they faced, particularly in moving from a small-scale DIY project to a legitimate business venture, which included learning about equity crowdfunding and establishing the necessary corporate structures to raise funds. The Moores delve into the technical aspects of their turbines, explaining how Harmony’s design differs from traditional wind turbines. They describe it as a modified Savonius vertical axis wind turbine with a unique helix twist, allowing it to capture wind from any direction and self-regulate its speed in high wind conditions by furling its blades. This furling capability, inspired by the yin and yang symbol, sets Harmony Turbines apart, offering a way to protect the turbine from damage while continuing to generate energy. They also discuss the ongoing development of their patented variable air gap generator, which promises greater efficiency but has been challenging to perfect and integrate with the turbine. Towards the end of the discussion, the Moores emphasize that Harmony Turbines is still in the research and development phase, and they are actively raising funds through StartEngine to continue their work. They invite listeners to consider investing in their company, highlighting that even small contributions can help them advance their innovative technology. The episode wraps up with a call to the audience to support or at least learn more about the groundbreaking work being done at Harmony Turbines.
