It's official — 2019 is the year of accelerators in Houston. Four different accelerator programs have announced plans to launch Houston programs this year so far — and they are all bringing something different to the table.

All four of the programs represent global programs or big companies recognizing the potential in Houston, which, according to Yael Hochberg, head of the Rice University Entrepreneurship Initiative, is a key part of the equation.

"When you're talking about a place like Houston, what we need here right now is interest from the outside," Hochberg says. "We need some certification by people from the outside that in fact this is a destination for innovation and entrepreneurship."

Houston's most successful accelerator has been homegrown — right out of the Texas Medical Center. TMCx is on its ninth cohort since it launched in 2014.

Also founded in Houston, SURGE Accelerator had a different fate. It launched in 2011 and closed in 2016. Hochberg says there are a number of reasons for the program's demise including disengaged corporations.

"I do feel there's a lot of opportunity around this, and I don't think we should look at SURGE as some sort of indicator of what will happen to an accelerator in the city," she says. "If anything, I would look at TMCx and look at the potential that we see from that."

The biggest benefit to these accelerator programs, Hochberg says, is the new influx of startups that come to Houston. It's not only the accelerators' cohorts, but just the feasibility of the success and resources available. More startups translates to more investments.

"When you have startup activity and good startups, then money, private investment money will follow," Hochbergs says. "Private investment money doesn't just show up."

But bringing in these programs puts the pressure on the city to focus on the environment it's providing new companies and talent. Innovative companies thrive in major metros with things like protected bike lanes, city living, sustainability — and Houston needs to work on these things, Hochberg says, adding that Houston's ability to boast on its single-family homes is less and less attractive to younger demographics.

Building the city up with these types of infrastructure is going to be key when it comes to retaining these startups that accelerators bring in.

"We can create accelerators from here until tomorrow," Hochberg says. "People will send a couple of people down for two days a week to Houston sit at the accelerator, but they'll keep their company somewhere else and not actually move to Houston. Maybe if you're lucky, they'll open up like a little satellite office. We don't want that."

So, what exactly are the differences between these four new startup accelerators? Here's a breakdown of each.

MassChallenge Texas first announced its Houston program in January. The Boston-based accelerator program is currently in its final phase of deciding its inaugural cohort. The program is for early stage companies, and is industry agnostic. Jon Nordby, former director of strategy at Houston Exponential, leads the Houston program as managing director.

Launch: July 2019
Location: Downtown Houston
Number of cohort companies: 25
Length: 6 weeks — July through August
Origin: Boston
Requirements: The program looks for applicants that haven't raised more than $500,000 in equity-based funding and have generated less than $1 million in revenue over the past year.
Equity requirements: None.
Prizes on the line: Free office space, mentorship, and, usually, monetary prizes. (Currently, the organization hasn't confirmed cash prizes for the inaugural cohort.)

Founder Institute

Founder Institute Houston is the earliest stage accelerator that's not associated with a university. Companies must be in the pre-funding stage of growth, and, while 30 companies will be chosen per cohort, only a fraction will complete the full 14 weeks. The Silicon Valley-originated concept now has chapters in almost 200 cities around the world. FI announced its new chapter in Houston in March after first launching in Austin.

Launch: May 2019
Location: Downtown (out of Station Houston)
Number of cohort companies: 30
Length: 14 weeks
Origin: Silicon Valley
Requirements: Company must be pre-funding.

Plug and Play Tech Center confirmed they were entering the Houston market earlier this month. The Silicon Valley organization has 30 locations all over the world and plans to open five new locations in the United States over the next six months to a year — one being Houston.

Launch: Fourth quarter 2019
Location: Currently scouting for a location.
Number of cohort companies: 20
Length: Three months, twice a year.
Origin: Silicon Valley
Requirements: The program is stage agnostic, but cohorts are focused on a specific industry. Houston's likely to be health and energy/sustainability, though nothing is set in stone.
Equity requirements: None
Prizes on the line: In-house venture capital opportunities, corporate connections, etc.

Ion Smart Cities Accelerator

In April, the city announced that Microsoft and Intel were backing a Smart Cities Accelerator program that would accelerate companies with solutions to some of Houston's key problems. The first cohort will be focused on solutions within resilience and transportation, but each cohort will have a different set of issues. With these rotating themes, every cohort will be different.

Launch: September 2019
Location: Station Houston (then later The Ion, when it opens)
Number of cohort companies: 10
Length: 10 months
Requirements: The first set of companies will be chosen for their ability to solve problems within mobility and transportation in Houston. (Other cohorts will have other topics.)
Prizes on the line: Pilot programs and permanent business from the city of Houston.

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.”
