Theoharis Dimarhos grew up in a family determined to follow tradition. As a child, his mother serenaded him with old Greek folk songs he still remembers, and his parents made speaking Greek a rule of the house. Dimarhos lived the immigrant family experience, and now he's developed a modern way to preserve pass down culture to the masses.

"My parents came from Greece in 1981, and in typical fashion, they didn't have much and didn't speak the language at all," says Dimarhos, who was born in Cleveland, Ohio. Living the first-generation American experience, he watched his parents work tirelessly to provide for the family and maintain their Greek culture in America.

Dimarhos did get his own immigrant story when his parents decided to move back to Greece when he was 7. After assimilating to Greece, he traveled back to the United States for college, where he learned to readjust once more.

"I kind of got that immigrant experience a couple of times," he says.

While Dimarhos grew up surrounded by his own heritage, he began to realize that "our native cultures were destined to fade if there wasn't a more modern way for children and our little siblings to learn more about their roots."

When talking with his friends from other countries outside of Greece, a general consensus grew: without modern learning, family heritage would slip away.

Enter: Ellis, an app that helps children connect to their culture. The app includes Greek songs, fables, mythology, history, and language.

Named after Ellis Island, a gateway into the United States for so many immigrants in history, Ellis nurtures Greek tradition in a way that caters to children through technology.

"I've always seen [Ellis Island] as a monument of courage to chase your dreams. . .people came and built this country, but also never forgot where they came from."

Interactive technology is becoming a large part of early childhood education, especially during COVID-19, as more families are at-home with children learning virtually. Children are the targets of over 80 percent of the top-selling paid apps in the education category of the iTunes store, according to a published analysis by Carly Shuler in 2012.

Dimarhos and his wife are deeply tied to their Greek heritage, and hope to pass that history and appreciation to their own children once they start a family.

"We wanted to make sure that there was a 21st century way for us and for our children to learn that goes beyond books," he says. "Something that's a little more immersive and fun — fun is very important — and educational."

Ellis is currently being beta tested with a group of 200 active users within the Greek community. The app, which targets ages 0-8, rolls out weekly content to parents.

"I'm receiving texts from friends who are parents begging me to put more content out because they need something to keep their children occupied," says Dimarhos. "Not only are regular schools closed, but cultural schools that are offered by the community are also closed and struggling to open back up."

Time spent on the app can be as short as five minutes and stretch into hours of learning time.

"The goal is always for children to pick up little phrases and words each time they listen," explains Dimarhos.

The stories and songs are all audio-based, tying into activities like waking up, eating breakfast, and bathtime.

"There's something magical about tying in an audio story or song with everyday tasks for kids," says Dimarhos.

Dimarhos parents see the app as "the next step of passing down the torch of our culture," he says.

"They tried to do it with the tools that they had for myself and my sister. . .We're trying to do the exact same thing that they did and their parents did, just with the tools that technology offers us," he says.

Dimarhos, who previously worked in economic development in Austin, had his first experience with startups when his former boss gave him a chance to work with his international accelerator for startups.

"I got my opening into the tech world through the international accelerator and seeing amazing immigrant founders create jobs and strive to do great things in America," he shares.

"Quite honestly, a startup that celebrates different cultures couldn't have a better home than in Houston," he says, noting the massive immigrant population and variety of cultures in the city.

In Dimarhos' own life, he's come across immigrants as well as first and second generation Americans who wish to preserve their own cultures.

"They've wished there was a more modern way to have access to those resources," he explains.

In the future, Dimarhos intends to quickly broaden the app to "launch in every immigrant community in the United States and around the world."

Connecting to cultural roots is something Dimarhos feels is "sacred" to immigrant families.

"It's something that you have the obligation from your parents as they give you everything for you to succeed in life. You kind of carry that obligation to carry that torch and pass it on to your children and their children," he explains.

"We grow up with that and the vision and the mission is just to create something that makes that a little bit easier to keep our cultures alive. I honestly think it's part of what makes this country great," he says.

Texas takes the No. 1 spot on new energy resilience report

Ranking It

A new report by mineral group Texas Royalty Brokers ranks Texas as the No. 1 most energy-resilient state.

The study focused on four main sources of electricity in hydroelectric dams, natural gas plants, nuclear reactors and petroleum facilities. Each state was given an Energy Resilience Score based on size and diversity of its power infrastructure, energy production and affordability for residents.

Texas earned a score of 71.3 on the report, outpacing much of the rest of the country. Pennsylvania came in at No. 2 with a score of 55.8, followed by New York (49.1) and California (48.4).

According to the report, Texas produces 11.7 percent of the country’s total energy, made possible by the state’s 141,000-megawatt power infrastructure—the largest in America.

Other key stats in the report for Texas included:

  • Per-capita consumption: 165,300 kWh per year
  • Per-capita expenditures: $5,130 annually
  • Total summer capacity: 141,200 megawatts

Despite recent failures in the ERCOT grid, including the 2021 power grid failure during Winter Storm Uri and continued power outages with climate events like 2024’s Hurricane Beryl that left2.7 million without power, Texas still was able to land No. 1 on an energy resilience list. Texas has had the most weather-related power outages in the country in recent years, with 210 events from 2000 to 2023, according to an analysis by the nonprofit Climate Central. It's also the only state in the lower 48 with no major connections to neighboring states' power grids.

Still, the report argues that “(Texas’ infrastructure) is enough to provide energy to 140 million homes. In total, Texas operates 732 power facilities with over 3,000 generators spread across the state, so a single failure can’t knock out the entire grid here.”

The report acknowledges that a potential problem for Texas will be meeting the demands of AI data centers. Eric Winegar, managing partner at Texas Royalty Brokers, warns that these projects consume large amounts of energy and water.

According to another Texas Royalty Brokers report, Texas has 17 GPU cluster sites across the state, which is more than any other region in the United States. GPUs are specialized chips that run AI models and perform calculations.

"Energy resilience is especially important in the age of AI. The data centers that these technologies use are popping up across America, and they consume huge amounts of electricity. Some estimates even suggest that AI could account for 8% of total U.S. power consumption by 2030,” Winegar commented in the report. “We see that Texas is attracting most of these new facilities because it already has the infrastructure to support them. But we think the state needs to keep expanding capacity to meet growing demand."

Intuitive Machines secures $175M equity investment to fuel growth

space funding

Houston-based space infrastructure and services company Intuitive Machines has secured a $175 million equity investment from unidentified institutional investors. The investors received shares of Class A stock in exchange for their funding.

Publicly held Intuitive Machines (Nasdaq: LUNR) says it plans to use the capital to help build revenue and invest in technology, including communications and data-processing networks.

“We are building a scalable infrastructure platform from low-Earth orbit to the moon and into deep space,” Intuitive Machines CEO Steve Altemus said in a news release. “With this investment, we can accelerate the integration of the combined company’s collective capabilities to deliver next-generation data, communications, and space-based infrastructure services.”

Intuitive Machines says the $175 million investment will improve its ability to secure deals for satellite systems, the proposed Golden Dome missile defense system and the proposed Mars telecommunications orbiter.

As the company pursues those deals, it’s seeking partners to develop space-based data centers.

The $175 million equity stake comes on the heels of Intuitive Machines completing its $800 million cash-and-stock purchase of Lanteris Space Systems. Intuitive Machines bought the satellite manufacturer from private equity firm Advent International.

In the third quarter, which ended Sept. 30, Intuitive Machines posted a $10 million net loss on revenue of $52.4 million.
