Solar-powered desalination device wins MIT $100K competition
Nona Desalination is developing a compact water-desalination device that requires less electricity than a cell phone charger

The winner of this yearís MIT $100K Entrepreneurship Competition is commercializing a new water
Nona Desalination says it has developed a device capable of producing enough drinking water
for 10 people at half the cost and with 1/10th the power of other water
desalination devices. The device is roughly the size and weight of a case of bottled water and is powered by a small solar
ďOur mission is to make portable desalination sustainable and easy,Ē said Nona CEO and MIT MBA candidate Bruce Crawford in the winning pitch
, delivered to an audience in the Kresge Auditorium and online.
The traditional approach for water desalination relies on a power-intensive process called reverse osmosis
. In contrast, Nona uses a technology developed in MITís Research Laboratory of Electronics
that removes salt
and bacteria from seawater using an electrical current
ďBecause we can do all this at super low pressure, we donít need the high-pressure pump
[used in reverse osmosis], so we donít need a lot of electricity,Ē says Crawford, who co-founded the company
with MIT Research
Scientist Junghyo Yoon. ďOur device runs on less power than a cell phone charger
The founders cited problems like tropical storms, drought, and infrastructure crises like the one in Flint, Michigan, to underscore that clean water access is not just a problem in developing countries. In Houston
, after Hurricane
Harvey caused catastrophic flooding in 2017, some residents were advised not to drink their tap water for months.
The company has already developed a small prototype that produces clean drinking water. With its winnings, Nona will build more prototypes to give to early customers.
The company plans to sell its first units to sailors before moving into the emergency
preparedness space in the U.S., which it estimates to be a $5 billion industry. From there, it hopes to scale globally to help with disaster relief. The technology could also possibly be used for hydrogen production, oil
and gas separation, and more.
