Great inventions reveal their value within due course, but there are those creations that tell their worth almost immediately, with a first look, image, or mere mention.

The Cold Cork, a malleable pouring device that instantly chills wine and spirits, falls into that category.

It seems like such a simple idea, but that’s the thing about inventions, isn’t it? Anyone can come up with an idea, but it’s the ones that can execute that idea that make it to the finish line and etch their names in the annals of creative glory.

“I had come home from the grocery store, right at the onset of COVID, and I wanted to have a glass of wine that I bought, but it was already room temperature, and I didn't want to put ice in it,” says wine-lover and former healthcare worker Michelle Kurkiewicz. “So, we started doing some research and came up with the idea for Cold Cork.”

Timing is everything, and because the nationwide pause caused by the COVID-19 pandemic offered Michelle, 33, and her husband Tyler, 30, plenty of free time, the dutiful duo was able to flesh out their labor of love.

As it turns out, Tyler, a mechanical engineer by trade, had recently purchased a 3D printer back in January 2020, so he was able to use it to build hundreds of prototypes in-house to eventually arrive at a final design, which is based on the couple’s wedding champagne flutes.

So how does the Cold Cork work? Picture this: the wine-lover takes the Cold Cork out of the freezer (after a recommended 24 hours to thoroughly freeze), places it on top of the open bottle of wine and begins to pour.

As the liquid funnels through the stainless-steel coil, which is surrounded by a proprietary, food-grade cooling medium, the wine or spirits is chilled by 20 degrees in just 20 seconds.

To achieve the best results for red wine, pour the entire bottle through the Cold Cork into a decanter and enjoy.

And the best part? Not one part of the Cold Cork’s signature process alters the taste or composition of the drink in any way.

“At first, we thought about whether the product should be inside the bottle or outside the bottle,” remembers Tyler. “But we quickly realized that there’s simply not enough room to do that amount of chilling inside a bottle. And we didn't want to have to pour any wine out. But we needed to make space to put some sort of chiller in the bottle. And so, we immediately started looking outside the bottle, and just with all the other wine gadgets, being bottle-topped and plugging in with a rubber stopper, that's immediately the direction we sort of drifted to.”

According to Tyler, the first couple of prototypes were made of a 3D filament. Initially, the idea was to focus on creating a cooling gel to compliment the coil, but that got a bit messy and, of course, there were too many wine taste-testing sessions to count.

“We definitely went through a lot of bottles of wine,” says Michelle. “But one of the first people that used our product was a sommelier and she loved it. We also gave one of our first production-level prototypes to a friend who is a manager at a restaurant. She used it on several occasions and said it was perfect for what she needed and seeing our product be used at a place that we frequented was extremely validating.”

Armed with the validation they needed to go to production, the wine-loving public could now have the product they needed to keep from having to throw all their wine in the refrigerator.

“The Cold Cork is really good for the people that maybe don't have those multi-zone fridges,” says Michelle. “We found a good niche with entry-level wine drinkers that don't have a wine fridge, but they want to drink their white wines still without being over-drank with ice cubes.

“That's really who we've been going after, and who we've seen has found a lot of value in the product. It's really the people that maybe aren't so prepared or maybe looking just for some more accessible solutions, whether it's because of the space in their apartment or financially, you know, it might be cheaper than a wine fridge. That's why we came up with the Cold Cork ourselves, because that was us, and so we kind of made a product that worked for us and found that there are a lot of people like that.”

The Cold Cork is available now and can be purchased directly from the company’s website for $64.95. In the future, more cork sizes and different colors will be offered, and more brick-and-mortar stores will carry the product. The couple pitched the idea and received investment from Trend Ventures at the 2022 Build Up Buttercup, an initiative that featured small business pitches for a select group of investors.

“We’ve gotten a lot of feedback directly from customers saying they use it a lot more than they thought,” says Michelle. “But then there are those people that are skeptical about how it works. That’s why I love to demo the Cold Cork in person.”

For a couple that met at a bar one night in downtown Houston, the Cold Cork is almost a poetic destination as a business endeavor and one that they both really relish.

“We both have our strengths, and we give each other a lot of support,” says Michelle.

“I’m very mechanically inclined, so I develop and invent, and Michelle is great with the marketing aspect and working with people to purchase the product,” adds Tyler. “In addition to the Cold Cork, we do have a couple of early projects that we are working on. I think there is a lot of opportunity with our technology to take what we have learned and fit that into different product lineups moving forward.”

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
