Nearly 100 energy tech startups pitched at the 19th annual Rice Alliance Energy Tech Venture Forum this week — and over a third of those companies are based in the Houston area.

At the conclusion of the event — which took place on Thursday, September 15, at Rice University, and included a day full of company pitches, panels, and thought leadership — 10 startups were deemed the most promising among their peers. The group was voted on by investors attending office hours ahead of the event.

The Rice Alliance for Technology and Entrepreneurship facilitated nearly 700 meetings between 70 investor groups and 90 ventures, according to the organization. The group of presenting companies included participants from Rice's Clean Energy Accelerator's first two cohorts.

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).
