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.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
