A team of Rice University engineering students has developed a new way for underwater robots to move around, save power and work more efficiently and quietly.

The robot uses reversible hydrogen fuel cell-based buoyancy control devices that convert water into hydrogen and oxygen (and the reverse) using electricity. Traditional underwater robots use thrusters or large pumps and propellers to change and hold depth, which can be heavy, have higher costs and use more energy. The use of reversible hydrogen fuel cells with balloons, allows the new robot to smoothly adjust its depth with less energy usage, according to a statement from Rice.

The project was part of a year-long senior design capstone by six students, known as Team Bay-Max, in Rice's Oshman Engineering Design Kitchen.

The students—Andrew Bare, Spencer Darwall, Noah Elzner, Rafe Neathery, Ethan Peck and Dan Zislis— won second place in the Willy Revolution Award for Outstanding Innovation at the Huff OEDK Engineering Design Showcase held at the Ion last month.

“Having spent a year on it now and putting so much time into it, getting to see the result of all that work come together is really rewarding,” Peck said in the statement.

“With a project like this, integration was critical,” Zislis added. “Another takeaway for me is the importance of determining a clear scope for any given project. With this robot, we could have focused on a lot of different things. For instance, we could have worked on improving fuel cell efficiency or making a robotic arm. Instead, we chose to keep these other elements simple so as not to divert focus away from the main part, which is the buoyancy control device. This kind of decision-making process is not just part of good engineering, but it’s relevant with everything in life.”

Elzner, for instance, focused on the dashboard that the robot feeds information to as it collects data from different sensors. It displays core system information, real-time graphs of the robot’s location and a simulation of its relative orientation, according to the statement.

Darwall, took a " deep dive into control theory and learn(ed) new software" to incorporate the video game joystick that allows the robot to combine manual control with an automatic stabilizing algorithm.

The proof-of-concept robot has potential applications in environmental monitoring, oceanographic research, and military and industrial tasks, according to Rice.

The team based the project on an academic paper by Houston researchers that showed that fuel cell-enabled depth control could reduce autonomous underwater vehicles’ energy consumption by as much as 85 percent.

It was authored by Rice professor Fathi Ghorbel and members of the University of Houston's Zheng Chen lab.

“This collaborative research aims to develop tetherless continuum soft engines that utilize reversible proton exchange membrane fuel cells and water electrolyzers to drive volume-mass transformation," Ghorbel said in a statement. "Through this design project, the BayMax team proved the efficacy of this technology in AUV interaction with the physical world.”

Ghorbel, Rice mechanical engineering lecturer David Trevas, and Professor in the Practice, Electrical and Computer and Engineering Gary Woods mentored the team.

Last month Rice also held its 24th annual Rice Business Plan Competition, doling out more than $1.5 million in investment and cash prizes to the top teams. Click here to see what student-led startups took home awards.

University of Houston receives $6.5M to go toward supporting equity, social justice, and more

funding moves

A recent gift to the University of Houston will provide support to a couple colleges on campus, including an endowed chair, a scholarship, and a lecture series.

Thomas Michael Panos Family Estate donated $4.5 million — and was matched with an additional $2 million by the University's new "$100 Million Challenge" Aspire Fund. It's the first matched gift of the new fund. The gift includes $2 million to create the Panos Family Endowed Chair in Mechanical Engineering, $2 million to establish a scholarship endowment beginning in 2022 to support need- and merit-based scholarships for full-time undergraduate or graduate students across UH, and $500,000 to support "The Panos Family Endowed Lecture in Equity and Social Justice" in the College of Liberal Arts and Social Sciences.

"We are incredibly grateful for the generosity of the Thomas Michael Panos Family Estate. This significant gift will not only help fuel academic success through innovation and discovery, but will support our ability to recruit renowned faculty and expand thought leadership," says Paula Myrick Short, UH senior vice president for academic affairs and provost, in the release. "The additional support for an equity and social justice lecture series is an especially timely and important part of our efforts to increase visibility around these issues."

Thomas Michael Panos emigrated to Houston from Greece and only had a sixth-grade education. His sons — Mike and Gus Panos — both earned college degrees in engineering.

"They were the kind of people who would help anybody," says Scott Harbers, who lived next door to the Panos family decades ago in what is now Midtown Houston, in the release. "As a family of immigrants, I know they would appreciate the diversity of the student body at the University of Houston. They had a tremendous interest in education and equal rights. I'm hopeful that this gift will help advance the lives of students who need help to complete their studies."

The $100 Million Challenge initiative was established in fall of 2019 thanks to an anonymous $50 million donation to the school, and the campaign is set on inspiring another $50 million in support of four areas that will address issues with major societal impact: sustainable energy and energy security, resilient infrastructure and smart cities, population health, and global engagement. Donors who commit $2 million to go toward an endowed chair will have their gifts matched through the program.

"The '$100 Million Challenge' is a transformational initiative to propel our academic enterprise to unprecedented levels of distinction, and this first matching gift launches us," says Eloise Brice, vice president for university advancement, in the release. "The work and research being done at UH, and accelerated through the Challenge, will have a tremendous impact on the quality of life for all Houstonians."

Axiom Space announces new CEO amid strategic leadership change

new leader

Six months after promoting Tejpaul Bhatia from chief revenue officer to CEO, commercial space infrastructure and human spaceflight services provider Axiom Space has replaced him.

On Oct. 15, Houston-based Axiom announced Jonathan Cirtain has succeeded Bhatia as CEO. Bhatia joined Axiom in 2021. Cirtain remains the company’s president, a role he assumed in June, according to his LinkedIn profile.

In a news release, Axiom said Cirtain’s appointment as CEO is a “strategic leadership change” aimed at advancing the company’s development of space infrastructure.

Axiom hired Cirtain as president in June, according to his LinkedIn profile. The company didn’t publicly announce that move.

Kam Ghaffarian, co-founder and executive chairman of Axiom, said Cirtain’s “proven track record of leadership and commitment to excellence align perfectly with our mission of building era-defining space infrastructure that will drive exploration and fuel the global space economy.”

Aside from praising Cirtain, Ghaffarian expressed his “sincere gratitude” for Bhatia’s work at Axiom, including his leadership as CEO during “a significant transition period.”

Bhatia was promoted to CEO in April after helping Axiom gain more than $1 billion in contracts, Space News reported. He succeeded Ghaffarian as CEO. Axiom didn’t indicate whether Bhatia quit or was terminated.

Cirtain, an astrophysicist, was a senior executive at BWX Technologies, a supplier of nuclear components and fuel, for eight years before joining Axiom. Earlier, Cirtain spent nearly nine years in various roles at NASA’s Marshall Space Flight Center in Huntsville, Alabama. He previously co-founded a machine learning company specializing in Earth observation.

“Axiom Space is pioneering the commercialization of low-Earth orbit infrastructure while accelerating advancements in human spaceflight technologies,” Cirtain said. “I look forward to continuing our team’s important work of driving innovation to support expanded access to space and off-planet capabilities that will underpin the future of space exploration.”

Among other projects, Axiom is developing the world’s first commercial space station, creating next-generation spacesuits for astronauts and sending astronauts on low-Earth orbit missions.

Houston billionaire benefactors will donate almost entire fortune to charity

Giving Back

Houston billionaires Rich and Nancy Kinder plan to donate an astounding 95% of their multi-billion-dollar wealth to charities, they told ABC13's Melanie Lawson.

The news comes as the Kinder Foundation announced an $18.5 million expansion project for Emancipation Park in the heart of Third Ward. That historic park was founded by slaves in 1872.

The Kinders are one of the wealthiest couples in the nation, worth $11.4 billion, according to Forbes. You've certainly seen the Kinder name on buildings and facilities around the city of Houston.

The Kinders are also among the most generous, giving away hundreds of millions to Houston institutions and charities. Their plan is to give away almost all of their wealth, or more than $10 billion.

Rich Kinder helped build oil and gas pipeline giant Kinder Morgan, but he stepped down as CEO more than a decade ago for a what he calls a bigger cause.

"Well, I think we'd all like to leave the world a little better place than we found it," he said. "And we just felt early on that the right thing to do was to try to give most or all of that away. So that's what we plan to do during our lifetime and after our death."

They found kindred spirits as one of the first couples to sign The Giving Pledge, established by billionaires Bill and Melinda Gates and Warren Buffett.

Mark Cuban calls AI ‘the greater democratizer’ for young entrepreneurs

eyes on AI

Texas billionaire Mark Cuban—whose investment portfolio includes Houston-based Holliball, a startup that makes and sells large inflatable holiday ornaments—believes AI is leveling the playing field for budding low-income entrepreneurs.

At the recent Clover x Shark Tank Summit in Las Vegas, the Shark Tank alum called AI “the greater democratizer.”

Cuban told Axios that free and low-cost AI tools enable disadvantaged teenagers to compete with seasoned professionals.

“Right now, if you’re a 14- to 18-year-old and you’re in not-so-good circumstances, you have access to the best professors and the best consultants,” Cuban said. “It allows people who otherwise would not have access to any resources to have access to the best resources in real time. You can compete with anybody.”

While Cuban believes AI is “the great democratizer” for low-income young people, low-income workers still face hurdles in navigating the AI landscape, according to Public Works Partners, an urban planning and consulting firm. The firm says access to AI among low-income workers may be limited due to cost, insufficient digital literacy and infrastructure gaps.

“Without adequate resources and training, these workers may struggle to adapt to AI-driven workplaces or access the educational opportunities necessary to acquire new skills,” Public Works Partners said.

Texas 2036, a public policy organization focused on the state’s future, reported in January AI jobs in Texas are projected to grow 27 percent over the next decade. The number 2036 refers to the year when Texas will celebrate its bicentennial.

As for the current state of AI, Cuban said he doesn’t think the economy is witnessing an AI bubble comparable to the dot-com bubble, which lasted from 1998 to 2000.

“The difference is, the improvement in technology basically slowed to a trickle,” Cuban said of the dot-com era. “We’re nowhere near the improvement in technology slowing to a trickle in AI.”
