NoNa Desalination converts saltwater cleaner into MIT $100K win


The winner of this year’s MIT $100K Launch competition is a portable desalination device that runs on less power than a cellphone charger and is the size of a case of bottled water.

NoNa Desalination will use its $100,000 winnings to put prototypes in the hands of its primary users — sailors — with an aim to reach U.S. emergency preparedness organizations soon after.

“We normally think of water scarcity as a problem for the developing world, but in reality it's a growing problem even for the developed world,” said Bruce Crawford, MIT Sloan MBA candidate and CEO of NoNa Desalination.

While hoarding bottled water might be the plan for many of us when faced with water emergencies caused by drought, tropical storms, or infrastructure problems, that’s not a good long-term plan, Crawford said. Bottled water is expensive, it takes up a lot of space, and it will eventually expire.

There are portable desalination devices currently on the market, but they tend to be heavy, bulky, and rely on high-pressure pumps to push the water through a filtering membrane, Crawford said.

NoNa’s technology passes the water through a channel and uses an electrical current powered by its solar panel to extract salt and bacteria. NoNa’s chief technology officer and its advisor are both authors on a paper that describes this approach to desalination.

“We are making portable desalination sustainable and easy,” Crawford said.

The event, which returned to an in-person venue after two years of a virtual competition, was the culmination of the MIT $100K Entrepreneurship Competition. The overarching competition is divided into Pitch, Accelerate, and Launch contests. Pitch judges 90-second elevator pitches, while Accelerate offers early-stage teams ideas and support from industry experts and entrepreneurs. The Launch competition encompasses whole business plans after a process of legal, design, and business mentorship.

The flagship competition started in 1989 and has served as the springboard for a variety of successful startups, including HubSpot and Akamai. Each year more than $300,000 in non-dilutive funding is awarded to the startup companies., which is using artificial intelligence to create more inclusive organizational and team cultures, took second place. RT Microfluidics, which is developing technology for at-home strep throat tests, took home third place. Both prizes are worth $5,000.

The $10,000 audience choice award went to Sparkle, a team developing a dye technology to help surgeons identify cancerous tumors.

The other 2022 finalists are:


Astrahl aims to build a new x-ray imaging system that uses nanotechnology for faster scans and lowering radiation exposure time.

Encreto Therapeutics

Encreto Therapeutics is using human intestinal cells to develop obesity treatments.


Iridence is designing sustainable biomaterials that can be used in things like paint and cosmetics.


Mantel is developing a carbon capturing system that works at high temperatures.
