It's been a busy past year or so for Nicolaus Radford, founder and CEO of Nauticus Robotics. He's taken his company public at a difficult time for the market, launched new partnerships with the United States Marine Corps, and even welcomed a new family member.

Originally founded in 2014 as Houston Mechatronics, Nauticus Robotics has designed a fleet of underwater robots and a software platform for autonomous operations. Radford caught up with InnovationMap about these recent milestones for him and the company in an interview.

"I look back on it and it's, you know, ringing the Nasdaq bell when we listed, and giving that speech at the podium — it was a surreal moment," he tells InnovationMap. "I was excited but cautious at the same time. I mean, the life of a CEO of a public company at large, it's all about the process following a process, the regulations, the administration of the public company, the filings, the reportings — it can feel daunting. I have to rise to the occasion to tackle that in this the next stage of the company." Read more.

A Houston startup that combines unique sensor technology with software analysis has raised its next round of funding to — according to Founder and CEO Josh Teekell — turbocharge its sales.

SmartAC.com's sensors can monitor all aspects of air conditioning units and report back any issues, meaning homeowners have quicker and less costly repairs. Teekell says he's focused on sales, and he's going to do that with the $22 million raised in the series B round that closed this month. He says the company will also grow its team that goes out to deploy the technology and train the contractors on the platform.

"This funding really buys us a couple years of runway through the end of next year and allows us to focus on getting to cash flow breakeven, which is right around our wheelhouse of our abilities here in the next 12 months," Teekell says. "In general, we've accomplished everything we'd be able to accomplish on the hardware side, and now it's just about deployment." Read more.

Researchers at the University of Houston and in Germany released a proof-of-concept paper this month that uncovers a new, fuel efficient means of transportation that they say could one day make air travel and traditional freight transport obsolete.

"I call it a world-changing technology,” Zhifeng Ren, director of the Texas Center for Superconductivity at UH and author of the paper, said in a statement.

Published in the journal APL Energy, the paper demonstrates a new way of using superconductors to move vehicles along existing highways while transporting liquified hydrogen at the same time. Until now, the costs of using superconductivity for transportation has held back innovation in the field. This model also reduces the need for a separate specialized pipeline system to transport liquified hydrogen that's able to keep the fuel source at minus 424 degrees Fahrenheit. Read more.

Researchers at the University of Houston and in Germany released a proof-of-concept paper this month that uncovers a new, fuel efficient means of transportation that they say could one day make air travel and traditional freight transport obsolete.

"I call it a world-changing technology,” Zhifeng Ren, director of the Texas Center for Superconductivity at UH and author of the paper, said in a statement.

Published in the journal APL Energy, the paper demonstrates a new way of using superconductors to move vehicles along existing highways while transporting liquified hydrogen at the same time. Until now, the costs of using superconductivity for transportation has held back innovation in the field. This model also reduces the need for a separate specialized pipeline system to transport liquified hydrogen that's able to keep the fuel source at minus 424 degrees Fahrenheit.

The model uses a similar concept to what's behind already existing magnetically levitating trains that operate on a magnetized rail, with superconductors embedded in the train's undercarriage. In Ren's model, superconductors would be embedded into existing highway infrastructure and magnets added to the undercarriages of vehicles. Liquified hydrogen would be used to cool the superconductor highway as vehicles move across it.

The idea could apply to trains, cargo trucks, and even personal cars, according to the paper. Better yet, the vehicles could travel up to 400 mph while on the highway. Drivers would then use the vehicle's traditional or electric motor once they exit.

"Instead of 75 mph, you could go 400 mph, from Houston to Los Angeles, or Houston to New York in just a few hours," Ren said in a statement.

Ren adds that this method would also require drivers to consume less fuel or power, cutting down on cost and environmental impact.

Technical and economic details still need to be addressed. But Ren believes "the project’s potential long-term economic and environmental benefits, would outweigh the upfront costs," according to a statement.

The paper joins a number of other innovative concepts coming out of UH in recent months. Recently, a research team at the university upgraded at-home rapid COVID-19 testing to make results more detectable via glow-in-the-dark materials.

Late last year the university also opened its

new tech transfer facility, and early this year it signed an agreement with India to bring a data center focused on energy to campus.

University of Houston designs device that instantly kills COVID-19

ZAPPING COVID-19

While the world rushes to find a COVID-19 vaccine, scientists from the University of Houston have found a way to trap and kill the virus — instantly.

The team has designed a "catch and kill" air filter that can nullify the virus responsible for COVID-19. Researchers reported that tests at the Galveston National Laboratory found 99.8 percent of the novel SARS-CoV-2 — which causes COVID-19 — was killed in a single pass through the filter.

Zhifeng Ren, director of the Texas Center for Superconductivity at UH, collaborated with Monzer Hourani, CEO of Medistar, a Houston-based medical real estate development firm, plus other researchers to design the filter, which is described in a paper published in Materials Today Physics.

Researchers were aware the virus can remain in the air for about three hours, which required a filter that could quickly remove it. The added pressure of businesses reopening created an urgency in controlling the spread of the virus in air conditioned spaces, according to UH.

Meanwhile, to scorch the virus — which can't survive above around 158 degrees Fahrenheit — researchers instilled a heated filter. By blasting the temperature to around 392 F, they were able to kill the virus almost instantly.

The filter also killed 99.9 percent of the anthrax spores, according to researchers.

A prototype was built by a local workshop and first tested at Ren's lab for the relationship between voltage/current and temperature; it then went to the Galveston lab to be tested for its ability to kill the virus. Ren says it satisfies the requirements for conventional heating, ventilation and air conditioning (HVAC) systems.

"This filter could be useful in airports and in airplanes, in office buildings, schools and cruise ships to stop the spread of COVID-19," said Ren, MD Anderson Chair Professor of Physics at UH and co-corresponding author for the paper, in a statement. "Its ability to help control the spread of the virus could be very useful for society."

Medistar executives are also proposing a desk-top model, capable of purifying the air in an office worker's immediate surroundings, Ren added.

Developers have called for a phased roll-out of the device, with a priority on "high-priority venues, where essential workers are at elevated risk of exposure — particularly schools, hospitals and health care facilities, as well as public transit environs such as airplanes."

The hope, developers add, is that the filter will protect frontline workers in essential industries and allow nonessential workers to return to public work spaces.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”

Intuitive Machines forms partnership with Italian companies for lunar exploration services

to the moon

Houston-based space technology, infrastructure and services company Intuitive Machines has forged a partnership with two Italian companies to offer infrastructure, communication and navigation services for exploration of the moon.

Intuitive Machines’ agreement with the two companies, Leonardo and Telespazio, paves the way for collaboration on satellite services for NASA, a customer of Intuitive Machines, and the European Space Agency, a customer of Leonardo and Telespazio. Leonardo, an aerospace, defense and security company, is the majority owner of Telespazio, a provider of satellite technology and services.

“Resilient, secure, and scalable space infrastructure and space data networks are vital to customers who want to push farther on the lunar surface and beyond to Mars,” Steve Altemus, co-founder and CEO of Intuitive Machine, said in a news release.

Massimo Claudio Comparini, managing director of Leonardo’s space division, added that the partnership with Intuitive Machines is a big step toward enabling human and robotic missions from the U.S., Europe and other places “to access a robust communications network and high-precision navigation services while operating in the lunar environment.”

Intuitive Machines recently expanded its Houston Spaceport facilities to ramp up in-house production of satellites. The company’s first satellite will launch with its upcoming IM‑3 lunar mission.

Intuitive Machines says it ultimately wants to establish a “center of space excellence” at Houston Spaceport to support missions to the moon, Mars and the region between Earth and the moon.
