Motion of the ocean brings fresh water to coastal communities

Motion of the ocean brings fresh water to coastal communities
Hurricane Katrina whipped up huge, powerful waves that caused severe destruction in 2005 along the U.S. Gulf Coast. Their size and strength convinced Phil Kithil of Santa Fe, New Mexico, there had to be a way to harness that energy. His first thought was a device that would use wave action to pump deep, cold seawater to the surface to dampen the intensity of hurricanes, which thrive on warm water.

Batteries absorb seawater to power long-range UUUVs

Batteries absorb seawater to power long-range UUUVs
The long range of airborne drones helps them perform critical tasks in the skies. Now MIT spinout Open Water Power (OWP) aims to greatly improve the range of unpiloted UUVs, helping them better perform in a range of applications under the sea. Recently acquired by major tech firm L3 Technologies, OWP has developed a novel aluminum-water power system that’s safer and more durable, and that gives UUVs a tenfold increase in range over traditional lithium-ion batteries used for the same applications.

'Tree-on-a-chip' generates passive hydraulic power

'Tree-on-a-chip' generates passive hydraulic power
Trees and other plants, from towering redwoods to diminutive daisies, are nature’s hydraulic pumps. They are constantly pulling water up from their roots to the topmost leaves, and pumping sugars produced by their leaves back down to the roots. This constant stream of nutrients is shuttled through a system of tissues called xylem and phloem, which are packed together in woody, parallel conduits.

The growing need for advanced water treatment

Sprawling cities gave way to the built up of waste, including dirty water. At first, cities were able to control the water going through the drains, but that is changing. Wastewater is a lot grittier and contains more contaminants than ever before. Water is still one of the earth’s most precious commodities, making it imperative that serious changes are implemented regarding how wastewater is treated.

Improved water splitting advances renewable energy conversion

Improved water splitting advances renewable energy conversion
Washington State University researchers have found a way to more efficiently create hydrogen from water - an important key in making renewable energy production and storage viable. The researchers, led by professors Yuehe Lin and Scott Beckman in the School of Mechanical and Materials Engineering, have developed a catalyst from low cost materials. It performs as well as or better than catalysts made from precious metals that are used for the process.

Water Industry gets smart on Big Data

The global market for control and monitoring systems in the water sector is estimated to be worth $21.3 billion in 2016, growing to $30.1 billion in 2021. Spending on advanced data management and analysis solutions is expected to grow even faster, at 11.9% a year. In the utility sector, spending on digital and smart solutions is estimated to be worth $17.7 billion in 2016. Managing water relies on heavy physical infrastructure and inherently reactive governing attitudes.
