A Houston nuclear engineer and entrepreneur wants consumers to capture their own ray of sunlight to brighten the prospect of making clean energy a bigger part of the power grid.

Solar Slice Founder Nathan Childress says his new venture offers a fulfilling way to encourage and promote solar energy and a greener planet. An experienced entrepreneur, Childress also serves as founder and CEO of technology software company Macorva.

Although trained in nuclear power plant design, solar power drew his interest as a cheaper and more accessible alternative, and Childress tells InnovationMap that he thinks that the transition to cleaner energy, in Texas especially, needs to step up.

With energy demand skyrocketing, and the push toward renewable solutions, solar seems like a safe bet for Childress, a former competitive high-stakes poker player. Childress cites a recent Yale University study that says 63 percent of Americans “feel a personal responsibility to help reduce global warming.”

But some studies show that 80 to 90 percent of the money invested into fighting climate change “aren’t going to things that people actually consider helpful,” he says.

“They’re more just projects that sound good, that are not actually taking any action,” says Childress, who has called Houston home for 25 years. He received his doctorate in medical physics at M.D. Anderson Cancer Center, where he worked on software that provided radiation therapy for patients.

The initial Kickstarter fundraising round, which will be launched soon, will finance the construction of one utility-scale solar farm, on about five to 10 acres, which would produce about 1 megawatt, or 1,000 kilowatts, of clean energy. The plant would make enough energy to power about 200 average homes.

Childress says interest has been strong, with several thousand signed up on the Kickstarter launch list. Some who are signed up expressed interest in a subscription, he said, and that may be offered later. Initially, though, for a one-time purchase of $95, a Solar Slice client can purchase one virtual 50W slice of solar power, produced by the farm. Over its lifetime, Childress says, that one purchase can offset three tons of carbon dioxide.

The app tracks carbon offsetting, and energy production for the slice, showing a client “exactly how much I have helped the climate, here’s exactly how (many) emissions I have prevented from putting in the atmosphere,” he says.

The energy produced by five slices can offset the average American’s carbon footprint for a year, and the power generated by the solar farm will be sold to the electric grid. As clients purchase more slices, they can earn eco-credits to donate to other climate-friendly partners, to plant trees or create pollinator habitats.

While Solar Slice is a for-profit venture, contributors won’t get rich or even make money from their purchase. Rather, it provides validation.

“Our focus is maximizing the real world impact, not for financial gain. This is not something people sign up (for) to make money. We’re really clear about that,” Childress says. “I want to show that it’s possible to have a for-profit company that is sustainable, that does good work.

“And hopefully, we can be part of the spirit…for a bigger movement, and for consumers and business, especially, to do things that matter.”

The largest U.S. solar plants are in Nevada and California, and those states are sites under consideration, but Childress says Texas is the most likely home for the initial project. The ten largest utility-scale solar plants in Texas by capacity are all in far west or central parts of the state, according to the state comptroller’s office.

Childress has a team of four, who are handling the marketing, plant design and site scouting, and hopes to hire five to 10 more, depending on response and growth. He says the Solar Slice consumer can directly connect in real time to the contribution that their purchase will make toward a green energy future.

“That was our inspiration..let’s start something that is really making a difference..and making really clear to the individuals what’s being done,” he says.

Solar energy has become a growing source of power for Texas, comprising about 6 percent of the state’s energy generation, as of 2022, the comptroller’s office says.

The state ranks first in projected growth of solar energy over the next five years, with more than 9,500 operating solar plants, and many thousands more announced, according to the state Public Utility Commission.

“We would absolutely love to make this into something where we are building plants around the nation, around the world,” Childress he says.

However, resistance to alternative energy projects like solar and wind, especially on a large scale, remains in some quarters.

Obtaining site permits for swaths of land can be also a challenge. For example, a recent survey by Berkeley Lab of 123 professionals from 62 unique, large-scale wind and solar energy facilities showed that about one-third of wind and solar siting applications in the past five years were canceled.

Half of the projects experienced delays of six months or longer. And according to the survey, developers expect the trend to continue, and become more expensive to address.

However, another Berkeley Lab survey of residents who live within three miles of a solar power plant showed that most view the plant positively. The larger the plant, the more negative the response in the survey. The smaller the farm, the more positive the reactions.

Childress says many of the common objections to utility-scale solar farms are misguided, and incorrect. For example, the concern that they would take over available farmland or take up too much space.

He says that even if the entire U.S. power grid relied solely on solar power, the plants would occupy not even a half percent of available land, which is about one percent farmland.

Houston falls from top 50 in global ranking of 'World's Best Cities'

Rankings & Reports

Houston is no longer one of the top 50 best cities in the world, according to a prestigious annual report by Canada-based real estate and tourism marketing firm Resonance Consultancy.

The newest "World's Best Cities" list dropped Houston from No. 40 last year to No. 58 for 2026.

The experts at Resonance Consultancy annually compare the world's top 100 cities with metropolitan populations of at least 1 million residents or more based on the relative qualities of livability, "lovability," and prosperity. The firm additionally collaborated with AI software company AlphaGeo to determine each city's "exposure to risk, adaptation capacity," and resilience to change.

The No. 1 best city in the world is London, with New York (No. 2), Paris (No. 3), Tokyo (No. 4), and Madrid (No. 5) rounding out the top five in 2026.

Houston at least didn't rank as poorly as it did in 2023, when the city surprisingly plummeted as the 66th best city in the world. In 2022, Houston ranked 42nd on the list.

Despite dropping 18 places, Resonance Consultancy maintains that Houston "keeps defying gravity" and is a "coveted hometown for the best and brightest on earth."

The report cited the Houston metro's ever-growing population, its relatively low median home values ($265,000 in 2024), and its expanding job market as top reasons for why the city shouldn't be overlooked.

"Chevron’s shift of its headquarters from California to Houston, backed by $100 million in renovations, crowns relocations drawn by record 2024 Port Houston throughput of more than four million containers and a projected 71,000 new jobs in 2025," the report said.

The report also draws attention to the city's diversity, spanning from the upcoming grand opening of the long-awaited Ismaili Center, to the transformation of several industrial buildings near Memorial City Mall into a mixed-use development called Greenside.

"West Houston’s Greenside will convert 35,000 square feet of warehouses into a retail, restaurant and community hub around a one-acre park by 2026, while America’s inaugural Ismaili Center remains on schedule for later this year," the report said. "The gathering place for the community and home for programs promoting understanding of Islam and the Ismaili community is another cultural jewel for the country’s most proudly diverse major city."

In Resonance Consultancy's separate list ranking "America's Best Cities," Houston fell out of the top 10 and currently ranks as the 13th best U.S. city.

Elsewhere in Texas, Austin and Dallas also saw major declines in their standings for 2026. Austin plummeted from No. 53 last year to No. 87 for 2026, and Dallas fell from No. 53 to No. 78.

"In this decade of rapid transformation, the world’s cities are confronting challenges head‑on, from climate resilience and aging infrastructure to equitable growth," the report said. "The pandemic, long forgotten but still a sage oracle, exposed foundational weaknesses – from health‑care capacity to housing affordability. Yet, true to their dynamic nature, the leading cities are not merely recovering, but setting the pace, defining new paradigms of innovation, sustainability and everyday livability."

Waymo self-driving robotaxis will launch in Houston in 2026

Coming Soon

Houston just cleared a major lane to the future. Waymo has announced the official launch of its self-driving robotaxi service in the Bayou City, beginning with employee-only operations this fall ahead of a public launch in early 2026.

The full rollout will include three Texas cities, Houston, Dallas, and San Antonio, along with Miami and Orlando, Florida. Currently, the company operates in the San Francisco Bay Area, Phoenix, and Los Angeles, with service available in Austin and Atlanta through Uber.

Before letting its technology loose on a city, Waymo first tests the routes with human drivers. Once each locale is mapped, the cars can begin driving independently. Unique situations are flagged by specialists, and engineers evaluate performance in virtual replicas of each city.

“Waymo’s quickly entering a number of new cities in the U.S. and around the world, and our approach to every new city is consistent,” explained the announcement. “We compare our driving performance against a proven baseline to validate the performance of the Waymo Driver and identify any unique local characteristics.”

The launch puts Waymo ahead of Tesla. Elon Musk’s Austin-based carmaker has made a lot of hullabaloo about autonomy being the future of the company, but has yet to launch its service on a wide scale.

Waymo started testing San Antonio’s roadways in May as part of a multi-city “road trip,” which also included Houston. The company says its measured approach to launches helps alleviate local concern over safety and other issues.

“The future of transportation is accelerating, and we are driving it forward with a commitment to quality and safety,” Waymo wrote. “Our rigorous process of continuous iteration, validation, and local engagement ensures that we put communities first as we expand.”

Shipley Donuts launches AI-powered ordering assistant

fresh tech

Popular Houston-born doughnut chain Shipley Donuts has added a first-of-its-kind AI-powered assistant to its online ordering platform.

The new assistant can create personalized order recommendations based on individual or group preferences, according to a news release from the company. Unlike standard chatbox features, the new assistant makes custom recommendations based on multiple customer factors, including budgetary habits, individual flavor preferences and order size.

"We're not just adding AI for the sake of innovation — we're solving real customer pain points by making ordering more intuitive, personalized and efficient," Kerry Leo, Shipley Vice President of Technology, said in the release.

The system also works for larger events, as it can make individual orders and catering recommendations for corporate events and meetings by suggesting quantities and assortments based on group size, event type and budget.

According to Shipley, nearly 1 in 4 guests have completed orders with the new AI technology since it launched on its website.

“The integration of the AI ordering assistant into our refreshed website represents a significant leap forward in how restaurant brands can leverage technology to enhance the customer experience,” Leo added in the release.
