Whether it’s on Mars or at the kitchen table, entrepreneur Bart Womack wants to change what and how you eat.

But the CEO and founder of next-generation farming startup Eden Grow Systems is seeking crowdfunders to help feed the venture.

The company evokes images of a garden paradise on earth. But the idea behind the Houston-based NASA spinoff came from a more pragmatic view of the world. Womack’s company sells indoor food towers, self-contained, modular plant growth systems built on years of research by NASA scientists looking for the best way to feed astronauts in space.

The company has launched a $1.24 million regulated crowdfunding campaign to raise the money it needs to scale and expand manufacturing outside the current location in Washington state.

Additionally, the U.S. Air Force recently chose Eden as a food source for the U.S. Space Force base on remote Ascension Island, in the Atlantic Ocean, Womack tells InnovationMap. Another project with Space Center Houston is also in the works.

“We want to be the government and DOD contractor for these kind of next-generation farming systems,” he says.

The Houston-based company includes former NASA scientists, like recent hire Dr. L. Marshall Porterfield, of Purdue University, as an innovation advisor.

Womack, a former digital marketer, Houston public channel show host, night club owner and entertainment entrepreneur, left those ventures in 2012, after the birth of his first child. While taking a year to study trends research, in 2014, what he read intrigued and alarmed him.

“I’ll never forget, I came across a report from Chase Manhattan Bank….of the top 10 disruptive investment sectors, over the next decade,” he says. “At the very top of the list was food.”

His conclusions on the fragility of the world’s food supply system, due to overpopulation, and scarcer land, led him to launch Eden in 2017, funded by venture capital firm SpaceFund, Womack, his family, friends and angel investors.

Womack believes “black swan” events will only increase, disrupting the food supply system and further jeopardizing food supplies.

“We’re going to enter a period of hyper novelty in history,” Womack says.. "The system we’ve built for the last 100 years, the super optimized system, is going to begin to break apart."

To avert a centralized food production outcome, operated by corporate giants like Amazon or Walmart, Womack’s vision offers a decentralized alternative, leaving it in local hands.

With $2 million put into the company so far and a half million-dollars in sales last year, Womack argues that Eden has achieved much and can make food independence within reach for everyday families.

The company commercialized NASA technology to fill what it viewed as “a huge gap within the controlled…agricultural space.”

The tower is the building block of a modular, automated and vertical indoor plant growth system, with calibrated misting, fans, and LED lighting, controlled by an app.

The company website touts the towers as an easy way to grow plants like lettuce, carrots, tomatoes, and potatoes, with little water, no soil, and lots of air, without the expense and work of cultivating an earth-based garden.

For those who want to eat more than greens, the towers provide a way to breed fish and shrimp in an aquaponic version, recycling fish waste as plant fertilizer.

However, big plans come with big costs. The towers range in price from $5,000 to $7,000, although payment plans for those who qualify make it affordable.

Eden has sold around 100 of their towers so far, to a variety of customers. But rising costs and shipping delays have led to a a three-month backlog.

The manufacturing and shipping associated with larger installations means that even if the company made a million-dollar sale, delivery of the product would take a year.

“One of the hardest things…as a start-up, the last couple of years, is trying to narrow down exactly where the biggest payback is,” Womack says. “There is the lower hanging fruit, of small sales to individual buyers, but there’s the larger fruit of institutional buyers. But they can take months and years to convert into an actual buyer.”

Customers include several universities, including Texas A&M University and Prairie View A&M University, and talks are underway with other large academic institutions.

For now, attracting investors so the company can reach its funding goal poses the biggest challenge.

“Texas investors are very, very hard-nosed, and they’re not like West Coast investors. They want to understand exactly how they’re going to get their money back, and exactly how quickly,” he says.

Womack says the crowdfunding round would allow the company to expand manufacturing operations into Houston, deliver product faster, and invest in advertising.

“When we complete this round, and become completely self sufficient, we’re planning on moving to a $25 million valuation,” Womack says. “We can show, given money, we can scale the company.”

The city of Nassau Bay, next to NASA’s Johnson Space Center, has purchased towers and plans to purchase more, not for the production of food, but to grow ornamental flowers.

Womack says that city officials there found that it’s cheaper to grow the decorative plants themselves, rather than buying them.

The towers are adaptable, and can grow not only food but cannabis and other plants, and if buyers want to use them other purposes, that adds to the product’s appeal, Womack says.

Eden has also sold some towers to Harris County Precinct 2 and the city of Houston, as part of a project he says will turn food deserts throughout the area into “food prosperity zones.”

“Our goal is to be the farming equivalent of Boeing,” Womack says.

New Gulf Coast recycling plant partners with first-of-kind circularity hub

now open

TALKE USA Inc., the Houston-area arm of German logistics company TALKE, officially opened its Recycling Support Center earlier this month.

Located next to the company's Houston-area headquarters, the plant will process post-consumer plastic materials, which will eventually be converted into recycling feedstock. Chambers County partially funded the plant.

“Our new recycling support center expands our overall commitment to sustainable growth, and now, the community’s plastics will be received here before they head out for recycling. This is a win for the residents of Chambers County," Richard Heath, CEO and president of TALKE USA, said in a news release.

“The opening of our recycling support facility offers a real alternative to past obstacles regarding the large amount of plastic products our local community disposes of. For our entire team, our customers, and the Mont Belvieu community, today marks a new beginning for effective, safe, and sustainable plastics recycling.”

The new plant will receive the post-consumer plastic and form it into bales. The materials will then be processed at Cyclyx's new Houston Circularity Center, a first-of-its-kind plastic waste sorting and processing facility being developed through a joint venture between Cyclix, ExxonMobil and LyondellBasell.

“Materials collected at this facility aren’t just easy-to-recycle items like water bottles and milk jugs. All plastics are accepted, including multi-layered films—like chip bags and juice pouches. This means more of the everyday plastics used in the Chambers County community can be captured and kept out of landfills,” Leslie Hushka, chief impact officer at Cyclyx, added in a LinkedIn post.

Cyclyx's circularity center is currently under construction and is expected to produce 300 million pounds of custom-formulated feedstock annually.

Houston quantum simulator research reveals clues for solar energy conversion

energy flow

Rice University scientists have used a programmable quantum simulator to mimic how energy moves through a vibrating molecule.

The research, which was published in Nature Communications last month, lets the researchers watch and control the flow of energy in real time and sheds light on processes like photosynthesis and solar energy conversion, according to a news release from the university.

The team, led by Rice assistant professor of physics and astronomy Guido Pagano, modeled a two-site molecule with one part supplying energy (the donor) and the other receiving it (the acceptor).

Unlike in previous experiments, the Rice researchers were able to smoothly tune the system to model multiple types of vibrations and manipulate the energy states in a controlled setting. This allowed the team to explore different types of energy transfer within the same platform.

“By adjusting the interactions between the donor and acceptor, coupling to two types of vibrations and the character of those vibrations, we could see how each factor influenced the flow of energy,” Pagano said in the release.

The research showed that more vibrations sped up energy transfer and opened new paths for energy to move, sometimes making transfer more efficient even with energy loss. Additionally, when vibrations differed, efficient transfer happened over a wider range of donor–acceptor energy differences.

“The results show that vibrations and their environment are not simply background noise but can actively steer energy flow in unexpected ways,” Pagano added.

The team believes the findings could help with the design of organic solar cells, molecular wires and other devices that depend on efficient energy or charge transfer. They could also have an environmental impact by improving energy harvesting to reduce energy losses in electronics.

“These are the kinds of phenomena that physical chemists have theorized exist but could not easily isolate experimentally, especially in a programmable manner, until now,” Visal So, a Rice doctoral student and first author of the study, added in the release.

The study was supported by The Welch Foundation,the Office of Naval Research, the National Science Foundation CAREER Award, the Army Research Office and the Department of Energy.

The EPA is easing pollution rules — here’s how it’s affecting Texas

In the news

The first year of President Trump’s second term has seen an aggressive rollback of federal environmental protections, which advocacy groups fear will bring more pollution, higher health risks, and less information and power for Texas communities, especially in heavily industrial and urban areas.

Within Trump’s first 100 days in office, his new Environmental Protection Agency administrator, Lee Zeldin, announced a sweeping slate of 31 deregulatory actions. The list, which Zeldin called the agency’s “greatest day of deregulation,” targeted everything from soot standards and power plant pollution rules to the Endangerment Finding, the legal and scientific foundation that obligates the EPA to regulate climate-changing pollution under the Clean Air Act.

Since then, the agency froze research grants, shrank its workforce, and removed some references to climate change and environmental justice from its website — moves that environmental advocates say send a clear signal: the EPA’s new direction will come at the expense of public health.

Cyrus Reed, conservation director of the Lone Star Chapter of the Sierra Club, said Texas is one of the states that feels EPA policy changes directly because the state has shown little interest in stepping up its environmental enforcement as the federal government scales back.

“If we were a state that was open to doing our own regulations there’d be less impact from these rollbacks,” Reed said. “But we’re not.”

“Now we have an EPA that isn’t interested in enforcing its own rules,” he added.

Richard Richter, a spokesperson at the state’s environmental agency, Texas Commission on Environmental Quality, said in a statement that the agency takes protecting public health and natural resources seriously and acts consistently and quickly to enforce federal and state environmental laws when they’re violated.

Methane rules put on pause

A major EPA move centers on methane, a potent greenhouse gas that traps heat far more efficiently than carbon dioxide over the short term. It accounts for roughly 16% of global greenhouse gas emissions and is a major driver of climate change. In the U.S., the largest source of methane emissions is the energy sector, especially in Texas, the nation’s top oil and gas producer.

In 2024, the Biden administration finalized long-anticipated rules requiring oil and gas operators to sharply reduce methane emissions from wells, pipelines, and storage facilities. The rule, developed with industry input, targeted leaks, equipment failures, and routine flaring, the burning off of excess natural gas at the wellhead.

Under the rule, operators would have been required to monitor emissions, inspect sites with gas-imaging cameras for leaks, and phase out routine flaring. States are required to come up with a plan to implement the rule, but Texas has yet to do so. Under Trump’s EPA, that deadline has been extended until January 2027 — an 18-month postponement.

Texas doesn’t have a rule to capture escaping methane emissions from energy infrastructure. Richter, the TCEQ spokesperson, said the agency continues to work toward developing the state plan.

Adrian Shelley, Texas director of the watchdog group Public Citizen, said the rule represented a rare moment of alignment between environmentalists and major oil and gas producers.

“I think the fossil fuel industry generally understood that this was the direction the planet and their industry was moving,” he said. Shelley said uniform EPA rules provided regulatory certainty for changes operators saw as inevitable.

Reed, the Sierra Club conservation director, said the delay of methane rules means Texas still has no plan to reduce emissions, while neighboring New Mexico already has imposed its own state methane emission rules that require the industry to detect and repair methane leaks and ban routine venting and flaring.

These regulations have cut methane emissions in the New Mexico portion of the Permian Basin — the oil-rich area that covers West Texas and southeast New Mexico — to half that of Texas, according to a recent data analysis by the Environmental Defense Fund. That’s despite New Mexico doubling production since 2020.

A retreat from soot standards

Fine particulate matter or PM 2.5, one of six pollutants regulated under the Clean Air Act, has been called by researchers the deadliest form of air pollution.

In 2024, the EPA under President Biden strengthened air rules for particulate matter by lowering the annual limit from 12 to 9 micrograms per cubic meter. It was the first update since 2012 and one of the most ambitious pieces of Biden’s environmental agenda, driven by mounting evidence that particulate pollution is linked to premature death, heart disease, asthma, and other respiratory illnesses.

After the rule was issued, 24 Republican-led states, including Kentucky and West Virginia, sued to revert to the weaker standard. Texas filed a separate suit asking to block the rule’s recent expansion.

State agencies are responsible for enforcing the federal standards. The TCEQ is charged with creating a list of counties that exceed the federal standard and submitting those recommendations to Gov. Greg Abbott, who then finalizes the designations and submits them to the EPA.

Under the 9 microgram standard, parts of Texas, including Dallas, Harris (which includes Houston), Tarrant (Fort Worth), and Bowie (Texarkana) counties, were in the process of being designated nonattainment areas — which, when finalized, would trigger a legal requirement for the state to develop a plan to clean up the air.

That process stalled after Trump returned to office. Gov. Greg Abbott submitted his designations to EPA last February, but EPA has not yet acted on his designations, according to Richter, the TCEQ spokesperson.

In a court filing last year, the Trump EPA asked a federal appeals court to vacate the stricter standard, bypassing the traditional notice and comment administrative process.

For now, the rule technically remains in effect, but environmental advocates say the EPA’s retreat undermines enforcement of the rule and signals to polluters that it may be short-lived.

Shelley, with Public Citizen, believes the PM2.5 rule would have delivered the greatest health benefit of any EPA regulation affecting Texas, particularly through reductions in diesel pollution from trucks.

“I still hold out hope that it will come back,” he said.

Unraveling the climate framework

Beyond individual pollutants, the Trump EPA has moved to dismantle the federal architecture for addressing climate change.

Among the proposals is eliminating the Greenhouse Gas Reporting Program, which requires power plants, refineries, and oil and gas suppliers to report annual emissions. The proposal has drawn opposition from both environmental groups and industry, which relies on the data for planning and compliance.

Colin Leyden, Texas state director and energy lead at the nonprofit Environmental Defense Fund, said eliminating the program could hurt Texas industry. If methane emissions are no longer reported, then buyers and investors of natural gas, for example, won’t have an official way to measure how much methane pollution is associated with that gas, according to Leyden. That makes it harder to judge how “clean” or “climate-friendly” the product is, which international buyers are increasingly demanding.

“This isn’t just bad for the planet,” he said. “It makes the Texas industry less competitive.”

The administration also proposed last year rescinding the Endangerment Finding, issued in 2009, which obligates the EPA to regulate climate pollution. Most recently, the EPA said it will stop calculating how much money is saved in health care costs as a result of air pollution regulations that curb particulate matter 2.5 and ozone, a component of smog. Both can cause respiratory and health problems.

Leyden said tallying up the dollar value of lives saved when evaluating pollution rules is a foundational principle of the EPA since its creation.

“That really erodes the basic idea that (the EPA) protects health and safety and the environment,” he said.
