Houston solar-powered tech company to collaborate on street safety device

lights on

Each K1 Super Tower, being created in partnership with Mountain View, California-based Knightscope, will include public safety technology.

EnGoPlanet, a Houston-based company that makes solar-powered street lights, is collaborating with a Silicon Valley company to create a solar-powered street light with emergency detection features.

Each K1 Super Tower, being created in partnership with Mountain View, California-based Knightscope, will include public safety technology such as:

  • Automated gunshot detection
  • Automated license-plate recognition
  • Blue strobe light
  • Mass-notification speaker
  • 360-degree, ultra-high-definition video

“We have been hard at work transforming conventional street lighting to one of the most advanced solar, battery, and LED solutions in the market — and we are excited to work with Knightscope to leverage that technology to further the public safety mission in an innovative way,” Petar Mirovic, CEO of EnGoPlanet, says in a news release.

Investors in EnGoPlanet, founded in 2019, include Houston-based Sallyport Investments and Paul Hobby, founding partner and managing director of Houston-based private equity firm Genesis Park.

Among the target customers for the K1 Super Tower are cities and colleges.

“Knightscope is rethinking every aspect of public safety technology,” says William Santana Li, chairman and CEO of Knightscope. “Pairing EnGoPlanet’s sustainable street lights with our innovative portfolio of capabilities will help illuminate more areas and set the new standard for city and campus safety.”

Knightscope, a publicly traded company, specializes in robotics and artificial intelligence geared toward public safety.

EnGoPlanet announced in April that it neared completion on its Calhoun County project that features 300 solar-powered, motion-activated street lights and 20 camera-equipped power poles at several local parks.

Greentown Labs combines forces with MassChallenge to support more climate startups

strategic partnership

Climatetech incubator Greentown Labs has formed a strategic partnership with global zero-equity accelerator MassChallenge.

The two organizations have headquarters in the Boston area, while Greentown Labs is also co-located in Houston. MassChallenge has a hub in Dallas, as well as others in Israel, Switzerland and the United Kingdom.

The new partnership aims to strengthen the ecosystem for early-stage climatetech startups by providing more mentorship, support and a broader commercialization network for members, according to a news release.

Greentown Labs will share its expertise with the 23 startups in MassChallenge's first climate-specific accelerator, known as the MassChallenge Early Stage Climate program. Additionally, Greentown Labs members will benefit from MassChallenge's network of expert mentors, judges, entrepreneurs, partners, investors, philanthropists and others.

“There are so many synergies and shared values between MassChallenge and Greentown that launching a collaboration like this feels like a natural next step for our organizations as we strive to support as many early-stage climate founders as possible,” Georgina Campbell Flatter, Greentown Labs CEO, said in the news release. “We want to reduce the friction and barriers to market for these climate entrepreneurs and ultimately increase their opportunity for success—ecosystem collaboration is an essential part of solving these challenges together.”

Combined, Greentown and MassChallenge report that they have supported more than 4,500 founders and more than 1,000 climate startups. MassChallenge has awarded more than $18 million in equity-free grants to startups, which have gone on to raise over $15 billion, since it was founded in 2009. Greentown Labs has helped more than 575 startups raise more than $8.2 billion in funding since it launched in 2011.

Greentown recently added five startups to its Houston community and 14 other climatetech ventures to its Boston incubator. It also announced its third ACCEL cohort, which works to advance BIPOC-led startups in the climatetech space, earlier this year. Read more here.

New research from Rice University that merges biology with electrochemistry has uncovered new findings on how some bacteria generate electricity.

Led by Caroline Ajo-Franklin, a Rice professor of biosciences and the director of the Rice Synthetic Biology Institute, the team published its findings in the journal Cell in April. The report showed how some bacteria use compounds called naphthoquinones, rather than oxygen, to transfer electrons to external surfaces in a process known as extracellular respiration. In other words, the bacteria are exhale electricity as they breathe. Continue reading.
