In the not-too-distant future, a Texas company's 3-D printed homes will be popping up across the world for a fraction of the cost of traditional homes.

"It's our mission at ICON to reimagine the approach to homebuilding and construction and make affordable, dignified housing available to everyone throughout the world," says Jason Ballard, co-founder and CEO of Austin-based ICON LLC. "We're in the middle of a global housing crisis, and making old approaches a little better is not solving the problem."

The 3-D printed homes startup just raked in $9 million in seed funding from a host of investors, including Fort Worth-based homebuilding giant D.R. Horton; Vulcan Capital, a Seattle investment firm launched by Microsoft billionaire Paul Allen, who died October 15; Austin startup accelerator Capital Factory; Austin real estate developer Cielo Property Group; and San Francisco venture capital firm Oakhouse Partners, which is the lead investor.

At this point, ICON executives aren't sure when their homes will be popping up around town. However, Ballard tells CultureMap, "serious conversations" are underway about bringing these homes to Austin and other places around the world.

In March, ICON reaped tons of press when it unveiled a 350-square-foot 3-D home at SXSW — the first home of its kind to receive a construction permit in the U.S. At the time, ICON executives said the home — constructed of concrete and printed in less than 48 hours by 3-D printing robots — cost less than $10,000. By contrast, the median price in September 2018 of a single-family home in the Austin metro area was $302,250.

ICON's first batch of homes is planned for a project in impoverished El Salvador that's being developed in conjunction with New Story, a San Francisco nonprofit that seeks to eradicate homelessness. The first homes there are scheduled to be printed next year.

ICON is targeting a per-home cost of $4,000 in El Salvador. Relying on technology upgrades, ICON hopes to create each 3-D home in less than 24 hours.

"While prices to print homes will vary from country to country and state to state," Ballard says, "the big takeaway is that downloading and printing a home has the potential to cost half of standard construction costs."

Homes at the development in El Salvador will measure 600 to 800 square feet — around the size of a typical one-bedroom apartment. Eventually, ICON aims to print homes in the 1,500- to 2,000-square-foot range.

Among the advantages of 3-D printed homes cited by ICON are:

  • Speedy construction
  • No manual labor
  • Little generation of leftover construction materials
  • "Tremendous" design freedom

There's a positive environmental impact with this construction process as well.

"Conventional construction is slow, fragmented, wasteful, and has poor thermal properties that increase energy use, increase operating costs, and decrease comfort," Ballard says. "Also, conventional materials like drywall and particleboard are some of the least resilient materials ever invented."

Texas-based energy startup raises $1 billion on heels of Houston expansion

Powering Up

Austin-based startup Base Power, which offers battery-supported energy in the Houston area and other regions, has raised $1 billion in series C funding—making it one of the largest venture capital deals this year in the U.S.

VC firm Addition led the $1 billion round. All of Base Power’s existing major investors also participated, including Trust Ventures, Valor Equity Partners, Thrive Capital, Lightspeed Venture Partners, Andreessen Horowitz (a16z), Altimeter, StepStone Group, 137 Ventures, Terrain, Waybury Capital, and entrepreneur Elad Gil. New investors include Ribbit Capital, Google-backed CapitalG, Spark Capital, Bond, Lowercarbon Capital, Avenir Growth Capital, Glade Brook Capital Partners, Positive Sum and 1789 Capital Management.

Coupled with the new $1 billion round, Base Power has hauled in more than $1.27 billion in funding since it was founded in 2023.

Base Power supplies power to homeowners and the electric grid through a distributed storage network.

“The chance to reinvent our power system comes once in a generation,” Zach Dell, co-founder and CEO of Base Power, said in a news release. “The challenge ahead requires the best engineers and operators to solve it, and we’re scaling the team to make our abundant energy future a reality.”

Zach Dell is the son of Austin billionaire and Houston native Michael Dell, chairman and CEO of Round Rock-based Dell Technologies.

In less than two years, Base Power has developed more than 100 megawatt-hours of battery-enabled storage capacity. One megawatt-hour represents one hour of energy use at a rate of one million watts.

Base Power recently expanded its service to the city of Houston. It already was delivering energy to several other communities in the Houston area. To serve the Houston region, the startup has opened an office in Katy.

The startup also serves the Dallas-Fort Worth and Austin markets. At some point, Base Power plans to launch a nationwide expansion.

To meet current and future demand, Base Power is building its first energy storage and power electronics factory at the former downtown Austin site of the Austin American-Statesman’s printing presses.

“We’re building domestic manufacturing capacity for fixing the grid,” Justin Lopas, co-founder and chief operating officer of Base Power, added in the release. “The only way to add capacity to the grid is [by] physically deploying hardware, and we need to make that here in the U.S. ... This factory in Austin is our first, and we’re already planning for our second.”

Expert on Houston’s energy advantage: Building affordability, reliability for all

Guest Column

As the energy capital of the world, Houston has been at the forefront of innovation, powering industries and communities for generations. Many Houston families, however, are facing a reality that undermines our leadership: high energy bills and ongoing concerns about grid reliability.

Affordability and reliability are not just technical issues; they’re equity issues. To remain the world leader in energy, we must ensure that every household has access to affordable and dependable power.

Affordability: The First Step Toward Equity

According to the recent 2025 study by The Texas Energy Poverty Research Institute, nearly 80% of low- to moderate-income Houstonians scaled back on basic needs to cover electric bills. Rising costs mean some Houstonians are forced to choose between paying their utility bill or paying for groceries.

Additionally, Houston now has the highest poverty rate among America’s most populous cities. Energy should not be a privilege for only half of our city’s population. That’s why affordability needs to be at the center of Houston’s energy conversation.

Several practical solutions exist to help address this inequity:

  • We can increase transparency in electricity pricing and help families better understand their electricity facts labels to make smarter choices.
  • We can expand energy efficiency programs, like weatherizing homes and apartments, swapping out old light bulbs for LEDs, and adopting smart thermostats.
  • Incentives to help families invest in these changes can deliver long-term benefits for both them and apartment complex owners.

Many small changes, when combined, can add up to significant savings for families while reducing overall demand on the grid.

Reliability: A Shared Community Priority

The memories of Hurricane Beryl, Derecho, and Winter Storm Uri are still fresh in the minds of Texans. We saw firsthand the fragility of our grid and how devastating outages are to families, especially those without resources to handle extreme weather. Reliability of the grid is an issue of public health, economic stability, and community safety.

Houston has an opportunity to lead by embracing innovation. Grid modernization, from deploying microgrids to expanding battery storage, can provide stability when the system is under stress. Partnerships between utilities, businesses, and community organizations are key to building resilience. With Houston’s innovation ecosystem, we can pilot solutions here that other regions will look to replicate.

Energy Equity in Action

Reliable, affordable energy strengthens equity in tangible ways. When households spend less on utilities, they have more to invest in their children’s education or save for the future. When power is stable, schools remain open, businesses continue to operate, and communities thrive. Extending energy efficiency programs across all neighborhoods creates a fairer, more balanced system, breaking down inequities tied to income and geography.

Studies show that expanding urban green spaces such as community gardens and tree-planting programs can lower neighborhood temperatures, reduce energy use for cooling, and improve air quality in disadvantaged areas, directly reducing household utility burdens.

In Houston, for example, the median energy burden for low-income households is 7.1% of income, more than twice that of the general population, with over 20% of households having energy burdens above 6%.

Research also demonstrates that community solar programs and urban cooling investments deliver clean, affordable power, helping to mitigate heat stress and making them high-impact strategies for energy equity and climate resilience in vulnerable neighborhoods.

Public-Private Partnerships Make the Difference

The solutions to affordability and reliability challenges must come from cross-sector collaboration. For example, CenterPoint Energy offers incentives through its Residential and Hard-to-Reach Programs, which support contractors and community agencies in delivering energy efficiency upgrades, including weatherization, to low-income households in the greater Houston area.

Nonprofits like the Houston Advanced Research Center (HARC) received a $1.9 million Department of Energy grant to lead a weatherization program tailored for underserved communities in Harris County, helping to lower bills and improve housing safety

Meanwhile, the City of Houston’s Green Office Challenge and Better Buildings Initiative bring private-sector sponsors, nonprofits, and city leadership together to drive energy reductions across millions of square feet of commercial buildings, backed by training and financial incentives. Together, these partnerships can result in real impact that brings more equity and access to affordable energy.

BKV Energy is committed to being part of the solution by promoting practical, consumer-focused strategies that help families save money and use energy more efficiently. We offer a suite of programs designed to provide customers with financial benefits and alleviate the burden of rising electricity bills. Programs like BKV Energy’s demonstrate how utilities can ease financial strain for families while building stronger customer loyalty and trust. Expanding similar initiatives across Houston would not only lower household energy burdens but also set a new standard for how energy companies can invest directly in their communities.

By proactively addressing affordability, energy companies can help ensure that rising costs don’t disproportionately impact vulnerable households. These efforts also contribute to a more resilient and equitable energy future for Houston, where all residents can access reliable power without sacrificing financial stability.

Houston as a Blueprint

Houston has always been a city of leadership and innovation, whether pioneering the space race, driving advancements in medical research at the Texas Medical Center, or anchoring the global energy industry. Today, our challenge is just as urgent: affordability and reliability must become the cornerstones of our energy future. Houston has the expertise and the collaborative spirit to show how it can be done.

By scaling innovative solutions, Houston can make energy more equitable, strengthening our own community while setting a blueprint for the nation. As the energy capital of the world, it is both our responsibility and our opportunity to lead the way to a more equitable future for all.

Houston professor awarded $2.6M grant for retina, neurological research

seeing green

University of Houston College of Optometry Professor John O’Brien has received a $2.6 million grant from the National Eye Institute to continue his research on the retina and neurological functions.

O’Brien is considered a leading expert in retinal neuroscience with more than 20 years of research in the field. The new funding will allow O’Brien and his team to continue to study the dense assembly of proteins associated with electrical synapses, or gap junctions, in the retina.

Gap junctions transfer electrical signals between neurons. And the plasticity of gap junctions changes the strength of a synapse, in turn changing how visual information is processed. Previous research has shown that reduced functions of electrical synapses could be linked to autism, while their hyperfunction may lead to seizures.

“The research we propose will significantly advance our understanding of the molecular complexes that control the function of electrical synapses,” O’Brien said in a news release.

The team at UH will work to identify the proteins and examine how they impact electrical synapses. It is particularly interested in the Connexin 36, or Cx36, protein. According to O’Brien, phosphorylation of Cx36, a short-term chemical modification of the protein, serves as a key driver of plasticity. And the protein has been linked to refractive error development, which is one of the largest vision problems in the world today.

Additionally, OBrien’s research has shown that plasticity is essential for all-day vision, allowing the retina to adjust sensitivity and sharpen images. He has also built a catalog of the core set of proteins surrounding electrical synapses that are conserved across species. His research has been funded by the NEI since 2000.
