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.

Uber, Nuro and Lucid plan to roll out robotaxi services in Houston

autonomous autos

More autonomous vehicles are expected to hit the roads in Houston next year.

Ridesharing giant Uber announced that it plans to roll out its premium robotaxi service in the Bayou City in mid-2027. Houston will be Uber’s second planned market for the program, following the San Francisco Bay Area, where the program is expected to be rolled out later this year.

Uber, Nuro and Lucid Group will bring the robotaxi program to Houston with more markets planned for the future. Currently, Nuro is conducting autonomous on-road testing with safety operators in Houston. Testing includes simulation, closed-course testing and supervised public-road testing.

“Houston is a city Nuro knows well, and we’re excited to help bring this robotaxi service to the city through our partnership with Uber and Lucid,” Andrew Chapin, chief operating officer at Nuro, said in a news release. “Houston’s large, complex metro area is an ideal market for demonstrating how Nuro’s universal autonomy platform can generalize across different geographies and operating environments. We look forward to continued engagement with the community as we prepare to launch service in 2027.”

The fleet of 100 vehicles across California and Texas will feature Lucid Gravity EVs and future Lucid Midsize vehicles equipped with Nuro Driver technology, Nuro’s Level 4 universal autonomy platform, plus a redundant sensor suite with cameras, lidar, radar and a roof-mounted halo.

The vehicles will be owned and operated by Uber and its fleet partners and made available to riders through the Uber network, according to the company.

In addition to the fleet of autonomous vehicles, Uber also announced that it has secured a 50,000-square-foot depot facility and dedicated charging pitstop in Houston. The facility will allow Uber and its partners to control vehicle maintenance, repairs, charging, cleaning, and day-to-day operations.

“Houston marks an important next step in our partnership with Lucid and Nuro as we expand autonomous mobility to more riders throughout the world,” Sarfraz Maredia, global head of autonomous mobility & delivery at Uber, added in the release. “Together, we’re combining best-in-class vehicle and autonomy technology with Uber’s scale, fleet operations expertise, and infrastructure capabilities to build a service that can grow across dozens of markets in the years ahead.”

Waymo launched its autonomous vehicle program in Houston in February.

The company later suspended its driverless car services in Houston, other major Texas cities, and Atlanta, after one of its vehicles was stranded by flooding during heavy rains. However, according to the Houston Chronicle, the fleet has resumed activity in Houston and is fully active.

Houston-based fintech company Receipts Depositary Corporation has closed a $7 million oversubscribed funding round and plans to scale.

The round was led by Austin-based LiveOak Ventures, with participation from Hivemind Capital, Onigiri Capital, OTC Markets Group, GTS, and Redbeard Ventures, according to a release from RDC.

RDC's platform issues depositary receipts (DRs) to qualified investors on digital and alternative assets, making it easier for investors to buy and trade hard-to-access and less traditional assets. Currently, the company offers DRs for cryptocurrencies including Bitcoin, Ethereum, Solana and XRP.

RDC says the new funding will allow it to launch new DR products across a wider range of asset categories, potentially including commodities. Additionally, it plans to grow its relationships with "banks, broker-dealers, market makers, custodians and exchange partners" and add to its product, operations, technology, and commercial functions teams. The company is actively hiring, according to a press release.

“Depositary Receipts are trusted, regulated capital markets products which RDC is bringing to an entirely new universe of assets, from commodities to digital assets, that have historically been out of reach of traditional securities markets," Krishna Srinivasan, founding partner at LiveOak Ventures, said the release. “The team's depth of experience in the DR business on a global scale, combined with the broad institutional validation from co-investors, anchor customers, and strategic partners across asset classes, makes RDC uniquely positioned to define this category. We're proud to lead this round and support the company as it scales.”

RDC was founded in 2022 by three Citibank alumni: CEO Ankit Mehta, CEO Bryant Kim and COO Ishaan Narain. It began offering its first DRs for Bitcoin in 2024.

“This funding round is a strong validation of what we’re building at RDC and the growing demand for modernized Depositary Receipt infrastructure,” Mehta added in the release. “With the support of LiveOak Ventures and our investor partners, we are accelerating development across our DR platform expanding our market reach, and building the team needed to support the next generation of DR product
