Vibhu Sharma observed a huge sustainability problem within the automotive industry, and he was tired of no one doing anything about it.

"Globally, humans dispose 1 billion tires every year," Sharma says on the Houston Innovators Podcast. "It's a massive environmental and public health problem because these tires can take hundreds of years to break down, and what they start doing is leaking chemicals into the soil."

Today, 98 percent of all tires end up in landfills, Sharma says, and this waste contributes to a multitude of problems — from mosquito and pest infestation to chemical leaks and fire hazards. That's why he founded InnoVent Renewables, a Houston-based company that uses its proprietary continuous pyrolysis technology to convert waste tires into valuable fuels, steel, and chemicals.

Houston-based SmartAC.com, which provides a customer loyalty management platform for contractors, has raised a follow-on round from Mercury Fund and other investors. The dollar amount of the round wasn’t disclosed.

An October filing with the U.S. Securities and Exchange Commission (SEC) indicates SmartAC.com planned to raise $8.2 million in venture capital. Of that sum, about $4 million had already been raised, the company reported, and nearly $4.2 million remained to be raised.

“Growing a business in the trades is all about customer loyalty, and loyalty is driven by optimizing the customer’s experience,” Josh Teekell, founder and CEO of SmartAC.com, says in a news release. Continue reading.

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from robotics to superconductivity — recently making headlines in Houston innovation.

Nicolaus Radford, founder and CEO of Nauticus Robotics

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.

Tesla forced to recall nearly all Cybertrucks in latest setback

Tesla Talk

U.S. safety regulators on Thursday recalled virtually all Cybertrucks on the road, the eighth recall of the Tesla-made vehicles since deliveries to customers began just over a year ago.

The National Highway Traffic Safety Administration's recall, which covers more than 46,000 Cybertrucks, warned that an exterior panel that runs along the left and right side of the windshield can detach while driving, creating a dangerous road hazard for other drivers, increasing the risk of a crash.

The stainless steel strip, called a cant rail assembly, between the windshield and the roof on both sides, is bound to the truck’s assembly with a structural adhesive, the NHTSA report said. The remedy uses an adhesive that’s not been found to be vulnerable to “environmental embrittlement,” the NHTSA said, and includes additional reinforcements.

Tesla will replace the panel free of charge. Owner notification letters are expected to be mailed May 19, 2025.

The recall of 46,096 Cybertrucks covers all 2024 and 2025 model years, manufactured from November 13, 2023, to February 27, 2025. The NHTSA order says that Tesla became aware of the problem early this year.

Videos posted on social media showing people ripping the panels off of Cybertrucks with their hands have gone viral in recent days.

The Cybertruck, which Tesla began delivering to buyers in late 2023, has been recalled eight times in the past 15 months for safety problems, including once in November because a fault in an electric inverter can cause the drive wheels to lose power. Last April, the futuristic-looking trucks were recalled to fix acceleration pedals that can get stuck in the interior trim. Other recalls were related to windshield wipers and the display screen.

It's the latest setback for the Elon Musk-owned electric automaker, which has come under attack since President Donald Trump took office and empowered Musk to oversee a new Department of Government Efficiency that’s slashing government spending.

While no injuries have been reported, Tesla showrooms, vehicle lots, charging stations and privately owned cars have been targeted.

Prosecutors in Colorado charged a woman last month in connection with attacks on Tesla dealerships, including Molotov cocktails thrown at vehicles and the words “Nazi cars” spray-painted on a building.

And federal agents in South Carolina last week arrested a man they say set fire to Tesla charging stations near Charleston. An agent from the Bureau of Alcohol, Tobacco, Firearms and Explosives wrote in an affidavit that authorities found writings critical of the government and DOGE in his bedroom and wallet.

Even before the attacks ramped up in recent weeks, Tesla has been struggling, facing increased competition from rival electric vehicles, particularly out of China.

Though largely unaffected by Thursday's recall announcement, Tesla shares have plummeted 42% in 2025, reflecting newfound pessimism as sales crater around the globe.

With regard to Thursday's recall, Cybertruck owners may contact Tesla customer service at 1-877-798-3752 and the National Highway Traffic Safety Administration Vehicle Safety Hotline at 888-327-4236, or go to nhtsa.gov.

$100,000 salary goes further in Houston than most cities, study shows

Cashing In

Even with Houston's ever-changing cost of living, earning a six-figure salary in the city is going much further than it used to, according to an income study by fintech company SmartAsset.

An annual $100,000 salary in Houston is worth $83,343 after taxes and when adjusted for the city's cost of living, the report revealed. That's $5,254 more than what six-figure-earning Houstonians were bringing home last year, a separate report from GoBankingRates.com found.

In SmartAsset's rankings of U.S. cities where $100,000 is worth the most, Houston ranked ninth.

The report warns a six-figure salary may seem comfortable at first, but it may not stretch as far depending on where an individual lives, any applicable tax obligations, and the rate of inflation.

"Earning $100,000 places an individual tax filer at the upper limit of the 22 percent federal tax bracket," the report's author wrote. "But taxes aren’t the only factor. The cost of living varies widely across the country, affecting how much purchasing power remains after necessary expenses."

Manhattan, New York is the No. 1 place where a six-figure salary is worth the least, where a New Yorker's take-home pay is only worth $30,362 after taxes and adjusted for the cost of living.

Other U.S. cities where a $100,000 salary goes the furthest
The U.S. city where a six-figure salary goes the furthest is Oklahoma City, where residents come away with $89,989 after all expenses.

Texas cities dominated the top 10 list. Texas doesn't impose state or local income taxes, which likely boosted its statewide six-figure salary value.

Six-figure earners living in El Paso see the greatest amount in take-home pay statewide, according to SmartAsset, with residents making $89,114 annually after taxes and expenses in 2025. That's $274 more than 2024's take-home pay.

The three additional Texas cities where a $100,000 salary goes the furthest after taxes and expenses are:

  • No. 3 – Corpus Christi ($88,015)
  • No. 6 – Lubbock ($86,846)
  • No. 7 – San Antonio ($86,084)

Six-figure salaries don't stretch as far in Dallas-Fort Worth. An annual $100,000 salary in Dallas is worth only $77,197 after taxes and expenses, which is about $900 less than what six-figure-earning Dallasites brought home in 2024.

Those living in Plano are taking home even less: The study says a Plano resident's six-figure salary is only worth $71,372 in 2025.

In the report's rankings of U.S. cities where $100,000 is worth the least, Plano ranked at No. 26, while Dallas ranked 38th.

SmartAsset used its paycheck calculator to apply federal, state and local taxes to an annual salary of $100,000 in 69 of the largest American cities, which was then adjusted for the local cost of living (which included average costs for housing, groceries, utilities, transportation, and miscellaneous goods and services).
