Alex Kurkowski can't count how many times he's gone looking for a greeting card — before some holiday, birthday, or special occasion — and found nothing that suited his recipient. He doesn't remember when he started editing them, either. For a few years now, he's been taking markers and pens to the greeting cards, blacking out words and scribbling new ones to say what he wanted to.

"They're templated. They're frozen, stagnant, fixed in what they are," Kurkowski says. "They suck."

But he can remember a few moments that changed that for him — and for Houston. When he started sending his family cards he'd sketched that depicted scenes from their lives, his classmates in the Rice University MBA program told him that, despite his pharmaceuticals background, this might actually be the right business for him.

Tellinga is hardly just a maker of greeting cards; it's in the business of storytelling, and customers can have personalized artworks delivered right to their mailboxes — a site for reclaiming, Kurkowski says, from the dread of bills and marketing materials.

"I'm trying to tap back into the tangible, physical and real side of life," Kurkowski says.

A year ago, Kurkowski sent his first Tellingas — short for "Telling a Story" — as an official business. He made the initial cards himself, but soon couldn't meet the demand on his own. Today, Tellingas are crafted from a cohort of more than 20 artists who are mostly Houston-based and, as Kurkowski says, make his work look like garbage.

Customers can select a few purchase options for customers, ranging from a one-panel story to 12 scenes. They upload a photo of the people they want drawn and submit their idea for the artwork on the website — they can create renderings of real-life events they want to remember or they might tell a wacky, fantasy story. For Kurkowski, the most important part is receiving the art over time — for example, the 12-panel pieces are sent over a one-month period.

Currently, Tellinga's only full-time staff is Kurkowski, but he's looking to hire a CTO to manage the growing demands of the website, where orders are placed. He also wants Tellinga to grow into the Airbnb model, with artists posting their works on his site and setting the price of their commissions themselves. Kurkoswki will be raising funds in the next investment round.

Until then, he's hoping to grow Tellinga's ability to turn stories into keepsakes — by offering ways to frame and preserve them, and by introducing a subscription model, so that customers can select days from of an entire calendar year to send their personalized artworks—constantly tapping back into that physical side of life like Kurkowsi wants.

"It's just cool because it's different," Kurkowski says. "It's getting away from the digital media world."

Houston researcher builds radar to make self-driving cars safer

eyes on the road

A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”

12 winners named at CERAWeek clean tech pitch competition in Houston

top teams

Twelve teams from around the country, including several from Houston, took home top honors at this year's Energy Venture Day and Pitch Competition at CERAWeek.

The fast-paced event, held March 25, put on by Rice Alliance, Houston Energy Transition Initiative and TEX-E, invited 36 industry startups and five Texas-based student teams focused on driving efficiency and advancements in the energy transition to present 3.5-minute pitches before investors and industry partners during CERAWeek's Agora program.

The competition is a qualifying event for the Startup World Cup, where teams compete for a $1 million investment prize.

PolyJoule won in the Track C competition and was named the overall winner of the pitch event. The Boston-based company will go on to compete in the Startup World Cup held this fall in San Francisco.

PolyJoule was spun out of MIT and is developing conductive polymer battery technology for energy storage.

Rice University's Resonant Thermal Systems won the second-place prize and $15,000 in the student track, known as TEX-E. The team's STREED solution converts high-salinity water into fresh water while recovering valuable minerals.

Teams from the University of Texas won first and second place in the TEX-E competition, bringing home $25,000 and $10,000, respectively. The student winners were:

Companies that pitched in the three industry tracts competed for non-monetary awards. Here are the companies named "most-promising" by the judges:

Track A | Industrial Efficiency & Decarbonization

Track B | Advanced Manufacturing, Materials, & Other Advanced Technologies

  • First: Licube, based in Houston
  • Second: ZettaJoule, based in Houston and Maryland
  • Third: Oleo

Track C | Innovations for Traditional Energy, Electricity, & the Grid

The teams at this year's Energy Venture Day have collectively raised $707 million in funding, according to Rice. They represent six countries and 12 states. See the full list of companies and investor groups that participated here.
