Seatrec’s infiniTE™ Float Surpasses 1,000 Dives for Naval Postgraduate School - Ushering a New Era of Long-Endurance Persistent Ocean Monitoring

Autonomous profiling float delivers oceanographic and acoustic data every six hours, fully powered by harvested energy from temperature gradients, marking a breakthrough in persistent, long-endurance ocean monitoring and real-time reporting for defense, scientific research, and exploration

 

VISTA, Calif. – WEBWIRE – Thursday, August 21, 2025

Seatrec, a leader in thermal-powered subsea drones, today announced a major milestone in oceanographic research with the 1,000th dive completed by its infiniTE™ float, deployed off the coast of Kona, Hawai’i, in collaboration with the Naval Postgraduate School (NPS). The float reached depths of 700 meters, diving into the deep sound channel for optimal listening, while producing more electricity than it consumed. The first-of-its-kind, an ocean-powered float carries a passive acoustic hydrophone, records sound data, processes data onboard, and transmits information and intelligence in real-time.

“Reaching 1,000 profiles is a critical endurance benchmark for our technology that unlocks exciting opportunities in ocean research and exploration,” explained Yi Chao, Ph.D., CEO and founder of Seatrec. “It is a significant achievement to demonstrate the capabilities of our infiniTE™ float to power multiple sensors with the energy from the ocean rather than relying on a limited battery.”

Launched on November 5, 2024, in collaboration with the NPS and funded by NPS’s Consortium for Robotics and Unmanned Systems Education and Research (CRUSER) program, this pioneering float known as the Persistent Smart Acoustic Profiler (PSAP) has harvested over 10 megajoules (2,800 Wh) of clean, renewable energy using Seatrec’s patented infiniTE™ technology, which converts natural ocean temperature gradients into electricity. Over just seven months, the infiniTE™ float has generated 2x the energy of a conventional battery-powered float while maintaining a net-positive energy balance. The harvested energy powers a Conductivity-Temperature-Depth (CTD) sensor and a passive acoustic hydrophone, onboard data processing, and satellite data transmissions, ushering in a new era of long-endurance, persistent ocean float missions.

NPS’s mission is to deliver defense-focused graduate education and interdisciplinary research to enhance the Navy’s operational effectiveness and technological leadership. “Through the Meteorology and Oceanography (METOC) program, NPS drives impactful results via innovative research and technology co-development. Our METOC student, Lieutenant Kirk Bienvenu, is analyzing PSAP data in his master’s thesis to advance maritime intelligence. By collaborating with startups like Seatrec, NPS equips officers with skills to address complex global threats, ensuring Navy readiness in dynamic operational theaters,” said John Joseph, the principal investigator and faculty associate for research at the Naval Postgraduate School.

PSAP represents an innovative way to collect and transmit oceanographic and underwater acoustic information essential to supporting critical Navy mission areas, including Undersea Warfare, Seabed Warfare, ISR and Maritime Domain Awareness. “Operating independently of other theater assets, PSAP provides a real-time feed of critical information directly to the warfighter, enhancing their tactical decision making,” Joseph said.

By combining a CTD sensor with a hydrophone, the infiniTE™ float enables simultaneous monitoring of both the ocean’s physical properties and acoustic soundscape. This breakthrough marks a turning point for persistent long-endurance, multi-sensor ocean observing missions once limited by battery constraints.

This milestone adds to a series of recent achievements by Seatrec, including:

  • Selection by Sea-Bird Scientific as the exclusive manufacturer of the Navis floats for the international Argo program.
  • A successful Arctic Power Station test at Michigan Tech’s Great Lakes facility.
  • Recognition as a winner of the U.S. Department of Energy’s Powering the Blue Economy™: Power at Sea Prize.

As the infiniTE™ float continues to demonstrate unmatched endurance and modularity, Seatrec is accelerating its vision to deliver scalable, self-powered solutions for defense, researchers, government agencies, and industry partners operating across the world’s oceans.

Seatrec Names Pentagon Alum Jason Stack to Advisory Board

Seatrec Names Pentagon Alum Jason Stack to Advisory Board

Extensive experience in developing and managing advanced autonomous naval and maritime systems will guide the commercialization and deployment of Seatec’s technology across the defense, research, and Blue Economy domains

VISTA, Calif. – WEBWIRE – Thursday, April 4, 2024. Seatrec, a renewable energy company that harvests energy from temperature differences in the environment, today announces the appointment of Jason Stack, Ph.D., an engineer and former Deputy Director of the Navy’s Unmanned Task Force at the Pentagon, to its advisory board.

“We’re rapidly commercializing autonomous systems powered by the ocean’s temperature differences for critical research and defense, as well as those that will help expand the Blue Economy,” points out Yi Chao, Ph.D., CEO and founder of Seatrec. “Jason’s unparalleled expertise gained from a distinguished career in the US Navy is a tremendous resource to help us accomplish our mission.”

Stack’s time at the Pentagon included multiple formal appointments within NATO including the US National Representative for Systems, Concepts, and Integration within the NATO Science & Technology Organization. Following his role at the Pentagon, he is co-founding a startup in the maritime space - still in stealth - and works as the company’s CTO.

He began his career designing and prototyping heavy equipment and industrial electronics at two manufacturing companies before earning his Ph.D. and moving to the Department of Defense (DoD). During his two-decade career at the DoD, Stack led programs at the Office of Naval Research (ONR) in maritime platform, sensor, perception, effector, and autonomy development. He then transitioned to an executive role where he acted as ONR’s Technical Director and served as director of the Ocean, Atmosphere, and Space Research Division before taking up his post at the Pentagon.

“Autonomous systems hold great potential for filling important capability gaps across a host of research, defense, and maritime missions but a reliance on batteries limits their endurance,” explains Stack. “Seatrec’s technology provides abundant power that is clean and sustainable to free those systems to reach their potential by providing robust function sets with near limitless endurance.”

Seatrec’s pioneering energy harvesting system uses phase change materials to harness energy from temperature differences between the ocean’s various depths. These materials contract and expand creating pressure that’s captured and converted into electricity. The clean, virtually limitless power enables scientists to integrate power-intensive sensors into its infiniTE float that were previously restricted by battery capabilities and lifespans.

Seatrec counts the US Navy’s Office of Naval Research among its early backers and in 2022 launched a project in partnership with the Naval Postgraduate School to integrate hydrophones into autonomous, ocean-going robots.

In 2023, the company was selected for the National Security Innovation Network (NSIN) Propel Hawai’i Accelerator. The program is a partnership between the NSIN and Decisive Point in collaboration with the U.S. Navy’s Pacific Fleet—the world’s largest fleet command encompassing 100 million square miles. Seatrec was selected from a competitive field of over 200 early-stage companies to join an elite cohort of enterprises developing cutting-edge technologies to help the modernization needs of the US Navy and the broader DoD community.

Oceanographic Team Wins NOAA Funding for the Autonomous Profiling Float Powered by Ocean’s Temperature Differences to Study Underwater Soundscape

World-class experts from Seatrec, Integral Consulting, Naval Postgraduate School, MBARI, and Scripps/UC San Diego to build a long-endurance float for gathering directional acoustic data in the deep ocean powered by clean, renewable energy.

 

VISTA, Calif. – WEBWIRE – Wednesday, September 13, 2023

SeatrecIntegral ConsultingMonterey Bay Aquarium Research Institute (MBARI)Naval Postgraduate School, and Scripps Institution of Oceanography at the University of California San Diego today announce funding from the National Oceanic & Atmospheric Administration’s (NOAA) Ocean Exploration. The two-year funding award supports the integration of a commercial, off-the-shelf directional hydrophone manufactured by GeoSpectrum Technologies Inc. onto Seatrec’s newly launched infiniTE™ float to study the ocean’s soundscape.

“Sound is a critical component to understanding the ocean, but the power demands of acoustic sensors make it impossible to listen for extended periods, not to mention the additional power required to process the acoustic data in order to reduce the data size for satellite communication,” points out Dr. Yi Chao, the Founder and CEO of Seatrec. “Seatrec’s newly launched infiniTE™ float, capable of generating electricity from temperature differences in the ocean, opens up vast new areas of knowledge to help us better understand and protect the ocean.”

Studies show that noise from humans adversely affects a broad range of organisms, from shellfish larvae to large marine mammals. Acoustic sensors, or hydrophones, are needed to quantify the impact of these noises; however, current technology limits their use to short deployments from expensive-to-operate ships or to areas where power is supplied via a cable from shore.

“A robust understanding of deep-sea acoustics is invaluable across a range of scientific, environmental, economic, and national security needs,” explains Dr. Kaus Raghukumar, an acoustic oceanographer at Integral Consulting. “The integration of a vector sensor into Seatrec’s profiler will leverage Integral’s NoiseSpotter® technology and expertise. A directional hydrophone allows for a better understanding of the location of sound sources, such as marine mammals.”

Seatrec’s infiniTE™ float provides a new platform for deep-water acoustic observations over unprecedented durations in remote regions.

“As part of NOAA Ocean Exploration’s mission to lead, coordinate, and fund expeditions around the world, we are uniquely situated to promote partners in the maritime community - like this creative team - who can advance ocean exploration technologies and acquire critical data and information about various marine environments,” said Jeremy Weirich, Director of NOAA Ocean Exploration. “Supporting this collaboration to develop and test an innovative sensor on a new underwater platform is important for filling data gaps about our ocean and enabling scientific discovery.”
