Combined Cycle Hydropower
Water upstream of a dam is diverted into a powerhouse. The potential energy created by the height of the dam is converted into kinetic energy. A portion of the kinetic energy is harnessed to generate electricity.
Abundant kinetic energy, in the form of high volumes of fast moving water, is released back into a waterway downstream of the dam.
An array of PDI hydrokinetic turbines extracts the otherwise wasted energy from the fast moving water exiting the powerhouse. Maximizing the use of existing power infrastructure.
Mr. Feldman is an accomplished energy industry executive with 20 years of experience in the energy and financial services industries. He is leading PDI in its efforts to commercialize a highly efficient, low cost hydrokinetic technology. Prior to co-founding PDI, he was Vice President of Project Development at Free Flow Power, where he advanced the largest pipeline of new hydropower projects in the U.S. from concept to commercial viability. He leads multidisciplinary teams of engineering, finance, regulatory and commercial experts who work together to develop energy projects with industry-leading reliability, economics, and efficiency.
Mr. Lissner is bringing experience from senior leadership positions at hydropower and energy efficiency companies to advance PDI's proprietary approach to hydrokinetic development. As VP of Operations and General Counsel of Free Flow Power, he led the team responsible for permitting and studying over 250 sites for hydropower development. Mr. Lissner collaborated with regulators and stakeholders to implement transformative changes to the regulatory process for hydropower, including the first-ever project to undergo a two-year Integrated Licensing Process and the coordination of stakeholders from seven states for systematic development of a 100+ hydrokinetic site portfolio that spanned 500 miles of the Lower Mississippi River. He is also the past General Counsel and VP of Administration of Next Step Living, a residential energy efficiency company which provided energy savings solutions to over 130,000 customers in Massachusetts, Connecticut, and New York. Mr. Lissner earned his B.A. from the University of Texas and his J.D. from the University of Virginia School of Law.
Dr. Buchanan is an Advisor Engineer at the Naval Nuclear Laboratory. His expertise is in computational fluid dynamics and validation experiments for single- and two-phase flows. Jack has published research in bio-fluid mechanics, gas-liquid two-phase flows, and boiling heat transfer spanning experimental methods and computational predictions. He serves as a reviewer for Department of Energy research proposals, several journals, and ASME and ANS conferences. He co-organized the first Symposium on CFD Verification and Validation at the ASME Fluids Engineering Division Summer Meeting. In his free time, Jack enjoys hiking, music, and is a lead mentor for FRC Robotics Team 3260.
He holds a B.S in Mechanical Engineering from Johns Hopkins University, and an M.S. and Ph.D. in Mechanical Engineering from North Carolina State University with a Computational Engineering and Sciences minor.
