Nearly two years after Hurricane Harvey battered the Houston area, a flock of electronic "rubber ducks" flew above homes in Katy in a broader endeavor to keep first responders and victims connected during natural disasters.

Developers and backers of Project Owl, an Internet of Things (IoT) hardware and software combination, conducted a pilot test of this innovation June 1 — the first day of this year's hurricane season. In the Katy test, 36 "ducks" took flight.

Bryan Knouse, co-founder and CEO of Project Owl (organization, whereabouts, and logistics), says the initiative marries:

  • A deployable IoT network of DuckLink devices that can quickly provide a basic WiFi setup where communications infrastructure might be down, like a region where a hurricane just hit. A single device can connect through WiFi to smartphones and laptops.
  • A software data visualization platform that speeds up and simplifies data monitoring on the Clusterduck network.

"So, our technology can be deployed to help communities that have been destroyed after natural disasters by providing quickly accessible communications network to coordinate and organize a response," Knouse tells InnovationMap.

The DuckLink network comprises hubs resembling rubber ducks, which can float in flooded areas if needed. It takes only five of these hubs to cover one square mile. This network sends speech-based communications using conversational systems (like Alexa and Facebook Messenger) to a central application. The app, the Owl software incident management system, relies on predictive analytics and various data sources to build a dashboard for first responders.

"Once this network of ducks is deployed and then clustered, civilians are able to basically get on the devices through a really intuitive interface and contact first responders with a list of things that are really essential to them," Project Owl team member Magus Pereira explained in an October 2018 blog post.

Project Owl, which won IBM's Call for Code Global Challenge in 2018, is being developed by Code and Response, an IBM program that puts open source technologies in communities that most need them. Knouse and Houston software engineer Charlie Evans lead Project Owl.

In a June 6 blog post, Evans recalled the widespread damage his hometown suffered during Hurricane Harvey and stressed the importance of efforts like Project Owl.

"The sheer magnitude of storms like this," Evans writes of Hurricane Harvey, "and the fact that extreme weather isn't going anywhere anytime soon, really drive home the point that effective communication and logistics are among the highest [priorities] for organizations that are involved with rescuing people and with cleanup."

Katy was the second pilot site for Project Owl. The first large-scale test was done in March in Puerto Rico.

Members of the Project Owl team were pleased with the Katy test. Knouse says the speed of DuckLink deployment improved versus the Puerto Rico test, and the network error transmission rate fell from more than 30 percent to around 10 percent.

"This test is important for anyone who wants to see how we will support communities during natural disasters," Knouse tells InnovationMap. "The growth and improvement [seen in the Katy test] confirms that we can continue to improve the speed, scale, and performance of the network, elevating confidence that if it's deployed during a real disaster, we can support recovery and critical life saving activities."

Following the Puerto Rico and Katy pilots, Project Owl will test the technology again later this year in Puerto Rico, as well as in Alabama, California, and Washington state, according to Knouse.

"It's one thing to build something in a lab and say, 'It works.' It's another to have complete strangers watch the technology deployment and say, 'It works — we need this as soon as possible.' And we are working at maximum capacity to make that happen," Knouse wrote in May.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
