Two Houstonians have developed a new system of harvesting solar energy more efficiently.

Bo Zhao, the Kalsi Assistant Professor of mechanical engineering at the University of Houston, along with his doctoral student Sina Jafari Ghalekohneh, have created a technology that theoretically allows solar energy to be harvested to the thermodynamic limit, which is the absolute maximum rate sunlight can be converted into electricity, as reported in a September article for Physical Review Applied.

Traditional solar thermophotovoltaics (STPVs), or the engines used to extract electrical power from thermal radiation, run at an efficiency limit of 85.4 percent, according to a statement from UH. Zhao and Ghalekohneh's system was able to reach a rate of 93.3 percent, also known as the Landsberg Limit.

To reach this new rate, the team proposed that a nonreciprocal STPV system be used, which reduces back emissions from the STPV to the sun within the technology's intermediate layer (or the side facing the sun).

"Our work highlights the great potential of nonreciprocal thermal photonic components in energy applications. The proposed system offers a new pathway to improve the performance of STPV systems significantly," Zhao says in the release. "It may pave the way for nonreciprocal systems to be implemented in practical STPV systems currently used in power plants.”

Additionally, the team also shows that STPVs can also be used with an economical thermal energy storage unit, allowing for solar energy to be generated 24 hours a day.

Houston is on the forefront of solar energy developments. In April, Mayor Sylvester Turner announced that the Texas Commission on Environmental Quality had granted a permit to transform a vacant landfill into the $70 million Sunnyside Solar Farm. It’s slated to be the largest urban solar farm in the country and will remove an estimated 60,000 tons of carbon dioxide from the air each year, according to officials.

Persona AI teams with Under Armour to protect next-gen robots

Future Fabrics

Houston-based Persona AI has cemented a partnership with sportswear manufacturer Under Armour to provide materials to protect future robots operating in dangerous conditions.

Through the partnership, Persona AI and Under Armour will launch a research initiative to explore whether advanced performance textiles can improve the durability and resilience of humanoid robots operating in harsh industrial environments.

“This is an opportunity to apply our innovation expertise in a new context,” Kyle Blakely, senior vice president of innovation, design studio, development, and testing at Under Armour, said in a news release. “Robotics presents a fascinating new design challenge, and we aim to play a leading role in shaping performance solutions for these environments. As humanoid systems take on more physically demanding roles, we see real potential to create new market opportunities, and we’re exploring how concepts like thermal management, abrasion resistance, and flexibility translate beyond sport."

Founded in June 2024 by former NASA engineer Nicolaus Radford and former Figure AI CTO Jerry Pratt, Persona AI has quickly risen to be a top name in the development of humanoid robotic systems. Radford previously was the principal investigator at NASA’s Dexterous Robotics Lab before becoming CEO of Nauticus Robotics. While at NASA, he was the chief engineer behind Robotnaut 2, the first humanoid robot on the International Space Station.

Persona AI raised $25 million in preseed funding to develop humanoid robots designed to operate in shipyards and other industrial sites. The company has inked partnerships with HD Korea Shipbuilding & Offshore Engineering, HD Hyundai Robotic, and Korean manufacturing firm Vazil Company to create and deploy humanoid robots for complex welding tasks in shipyards.

These environments often involve exposure to dangerous chemicals, harsh weather and other potential hazards. The partnership between Persona AI and Under Armour will combine the clothing manufacturer’s development of resilient but flexible materials with the humanoid design of Persona AI.

Though best known for its sportswear, Under Armour produces a wide range of specialist fabrics and clothing, including an entire line used by the U.S. military. The company’s track record of developing high-performance fabrics built to withstand war zones and desert conditions makes it a strong partner in Persona AI’s latest endeavor.

“We chose to work with Under Armour because of their track record of innovation with these types of performance materials,” Radford said. “As we develop humanoids for intense and potentially hazardous environments, this collaboration helps us understand how advanced materials can enhance long-term reliability, thereby informing solutions to better protect workers in the field.”

Waymo suspends robotaxi service in Houston due to weather concerns

Transportation news

Waymo has suspended driverless car services in Houston and other major Texas cities, and in Atlanta, after one of its vehicles was stranded by flooding during heavy rains that will likely also hinder travel in a large swath of the U.S over the holiday weekend.

Severe thunderstorms with large hail and gusty winds were possible Friday, May 22 in Texas and other parts of the Southern and Central Plains, the National Weather Service said.

Forecasters warned of possible flash flooding along the Gulf Coast of Texas and Louisiana on Saturday, when rain and thunderstorms were expected across much of the central and eastern U.S.

The Waymo vehicle got stuck during a downpour in Atlanta on Wednesday that flooded streets and even part of a downtown highway. The vehicle was not occupied and was later recovered, the company said in a statement. At least one other Waymo vehicle was waylaid during the storm.

Waymo serves only the city of Atlanta in Georgia, and services Dallas, Houston, Austin, and San Antonio in Texas.

The company paused service in Texas “out of an abundance of caution for the forecasted severe weather,” the statement said.

Global summit spotlights Houston's growing role in brain health, innovation

where to be

The Center for Houston’s Future and UTMB are bringing the Texas Brain Economy Summit back to Houston this summer to continue to position the region as a global leader in brain health.

Led by Rice Brain Institute, The University of Texas Medical Branch's Moody Brain Health Institute and Memorial Hermann’s comprehensive neurology care department, the initiative aims to advance the understanding, prevention and treatment of the brain. It was developed on the heels of Texas voters overwhelmingly approving a ballot measure to launch the $3 billion, state-funded Dementia Prevention and Research Institute of Texas (DPRIT).

“Texas voters, by approving the state-funded Dementia Prevention Institute, have shown a strong commitment to brain health, as scientific advances continue daily. [Project Metis] aims to harness the Houston region’s unique strengths: its concentration of leading medical and academic institutions, a vibrant innovation ecosystem, and a history of entrepreneurial leadership in health and life sciences,” Gow said at the time.
