A healthy foods concept has selected Houston as its next spot to bring its salad-making robot — aptly named Sally. The Salad Station, a Louisiana-based restaurant group, has partnered with California-based Chowbotics to bring salad-making vending machines to Houstonians.

Chowbotics invented Sally, which serves customizable, made-to-order salads, snacks, breakfast bowls, and grain bowls. Scott Henderson, founder and president of The Salad Station, tells InnovationMap that the discussion with Chowbotics about being the company's operational manager started in 2018.

"In seven states, from Texas to Florida, The Salad Station does operations for Sally the robot," says Henderson. "We both have a passion for bringing fresh products to people as many hours of the day as possible."

Henderson tells InnovationMap that he saw potential for the robot to increase opportunities for the chain's franchisees, increasing the amount of locations one person could own.

"We started looking at locations for Sally the robot and just in the Texas Medical Center alone, we feel like it could be 60 to 80 placements," says Henderson.

Due to the massive potential, The Salad Station entered into a partnership with Houston-based RoboFresh as the group's commissary to bring in more than 100 robots by 2022. Henderson tells InnovationMap that there will be 10 salad-making robots in the Texas Medical Center by 2020.

According to Henderson, the robot holds 22 unique ingredients, including two different lettuces, six topping options, and a dressing. The customer is able to customize their ingredients to create the salad of their choice. Payment is completed by credit card or Apple Pay, with most salads costing $7 to $8.

Henderson tells InnovationMap that the number one question they are asked at salad robot facilities is how the machine's ingredients stay fresh.

"We service the machines, at a minimum, twice a day, everyday," says Henderson. "Every morning and afternoon, we have people that go to the robots to bring fresh ingredients and to sanitize the outside of the machine."

Each ingredient is loaded in an airtight container, Henderson says.

"So, from the prepping in our Salad Station restaurants to delivering and installing it, there is no touch of product," says Henderson.

Henderson tells InnovationMap that each canister has an expiration date. For example, the expiration date on spinach is two days, so if the ingredient is not sold within that time frame, it no longer shows an option for the customer.

"Anytime the robot goes over 41 degrees for more than five minutes it disables itself, so customers cannot use the machine until we come back on site and change out the ingredients," says Henderson, adding that the robot maintains a consistent temperature of 34 degrees, keeping produce fresh and crisp.

The salad vending machines are just the beginning of growth in the Space City. The Salad Station is expanding into the Houston area with their first local brick and mortar location in Webster. In addition to the new opening, the franchise is expected to open additional locations across the greater Houston area in the next few years.

"That's where we're at for Texas, we're searching for local people, mainly in the Houston surrounding areas, that want to own their own business," says Henderson.

He adds that he believes the company's family-friendly values and hours will draw in more individuals to help open franchise locations of the fresh food chain.

The Salad Station was founded by Scott Henderson and his mother and business partner Cindy Henderson in 2012, the first store opening in Hammond, LA. Henderson tells InnovationMap that he started franchising the concept in 2014 and locating partners in nearby states to bring The Salad Station to new markets. The restaurant group currently has locations in Louisiana, Mississippi, Alabama, and Florida.

Johnmike Heroman, the head of franchise development at The Salad Station, tells InnovationMap that the chain is currently looking for potential franchise owners in the Houston area and feedback on placement options for Sally's next location.

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.”
