Pliant Energy Systems

Who We Are
We are a pioneering engineering firm based in the Brooklyn Navy Yard in Brooklyn, New York. Our core mission is to conceptualize, patent, and develop truly novel fluid‑interaction technologies that reshape how propulsion, energy, and pumping systems work.

What Makes Us Different
Our technologies operate without spinning blades—using undulating surfaces instead—to interact with fluids. This groundbreaking paradigm, deeply rooted in our 22+ patents and trade secrets, breaks away from traditional approaches to offer disruption in propulsion, energy harvesting, and water delivery.

Our Specialized Services
– Marine Robotics & Propulsion – We’ve developed agile amphibious platforms like Velox and C‑Ray, designed to operate in water, on land, and over snow or ice.
– Energy Harnessing – Our blade‑less fluid interaction designs enable electricity generation from rivers and streams.
– Passive Irrigation Pumping – We deliver low‑energy pumping solutions, important for clean water and irrigation in underserved regions.

Our Commitment to Quality
Supported by extensive numerical modeling, laboratory testing, and prototype building, our R&D effort is grounded in rigor and integrity. We’ve secured federal and state funding, including dozens of grants and contracts from the U.S. Office of Naval Research (ONR), Department of Energy (DOE), NSF, USDA, and NYSERDA.

Why Clients Trust Us
Industry and government partners rely on us for cutting‑edge research and development. We regularly showcase our work at major events—including the Sea Air & Space Expo, Marine Corps demonstrations, and offshore wind innovation cohorts—and have secured multi‑million‑dollar contracts, such as the $8 million ONR open‑ocean platform development contract.
