Making converters better absorb power of ocean waves

Making converters better absorb power of ocean waves
Compared to wind and solar energy, wave energy has remained relatively expensive and hard to capture, but engineers from Sandia National Laboratories are working to change that by drawing inspiration from other industries. Sandia's engineering team has designed, modelled and tested a control system that doubles the amount of power a wave energy converter can absorb from ocean waves, making electricity produced from wave energy less expensive.

Impact of Amazonian hydropower may be greater than predicted

Impact of Amazonian hydropower may be greater than predicted
  The environmental impact of hydropower generation in the Amazon may be greater than predicted, according to new University of Stirling research. The study suggests that estimates of biodiversity and carbon losses associated with tropical hydropower may be higher than estimated as they fail to consider the full impact of forest fragmentation.

Tidal energy: the opportunities and the challenges

Tidal energy: the opportunities and the challenges
Research which has been published by the NSRI (National Subsea Research Initiative), has identified the potential enablers which will assist subsea supply chain companies to break into the growing wave and tidal energy sectors, and associated technological barriers to their progress

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.
