Oceans absorb the carbon dioxide, which in turn changes the water's pH acidity levels. What this means is that coral reefs are growing at a slower rate and the survival of marine species is decreasing, according to NOAA.
Now, the speed at which ocean pH level is changing is faster than any time in the last 300 million years, according to a new … Read more
Imagine if Google Earth could take users under the ocean. People on laptops sitting hundreds of miles away from any body of water could dive down and spot colorful reef fish, coral forests, sea snakes, and rare turtles. A program just like this was officially announced today.
In a partnership with Google, the global insurance company Catlin Group Limited and nonprofit Underwater Earth launched the Catlin Seaview Survey. The goal is to let people explore the ocean from afar and also carry out the first detailed study about the composition and health of coral reefs. The mapping expedition is expected … Read more
commentary Some of IBM's distinguished engineers may want to review the laws of thermodynamics.
The computing giant today announced its "IBM 5 in 5" predictions of five technology developments in the next five years. The most provocative is mind reading, to understand brain disorders, or where sensors will be able to translate people's thoughts into actions, such as operating a computer.
The least plausible perhaps is the idea that homes will be powered by human motion. In a video on its "People power comes to life" prediction, an IBMer says "you will be … Read more
Harnessing energy from the oceans involves a lot more than putting a generator in the water.
IBM Research today announced a project to monitor the impact of noise on marine ecosystems from a wave energy generator in Ireland. Done in conjunction with the Sustainable Energy Authority Ireland, its part of an ongoing SmartBay project to monitor the environment of Galway Bay with sensors and telemetry to advance ocean energy.
To monitor the acoustic impact of wave power, a generator from OceanEnergy in Ireland is equipped with audio sensors. Data from the sensors is fed continuously to IBM's data centers … Read more
Philadelphia-based Quench has garnered $30 million in funding for expansion, the company announced Thursday.
Quench makes water coolers with built-in filtration systems that tap into a building's existing water supply instead of using water in five-gallon plastic jugs that need to be regularly delivered and replaced. The company makes free-standing and countertop water coolers and ice makers.
The coolers use a reverse osmosis water filtration system that includes a sediment filter, an antimicrobial filter for killing microorganisms, a carbon filter that removes things like chlorine that might change water flavor, and a lead filter for reducing heavy metal content. … Read more
General Electric, NRG Energy, and ConocoPhillips, through their joint venture firm, have invested in a new kind of wastewater treatment technology.
They're backing Israel-based Emefcy, developer of the Megawatter System, which uses bacteria to turn a regular wastewater treatment plant into an electricity-producing bioreactor that produces both clean water and electricity.
The electrogenic bioreactor draws on organic matter in the wastewater to supply microbial fuel cells (MFCs). It uses the electrogenic bacteria Shewanella, Geobacter, and Rhodoferax as catalysts to decompose the glutens in the water.
The Megawatter System is not built as a standalone plant, but is actually a … Read more
BOSTON--It's a business with extremely risk-averse customers that have little money spend. On the plus side, it's vital to life and a strained natural resource.
Water purification and treatment techniques continue to attract bright ideas from researchers and entrepreneurs, but getting beyond a nifty prototype is challenge they all face, said a panel here at the TechConnect World conference on clean tech and nanotechnology.
Many of the municipal water treatment and distribution systems in the U.S. are in desperate need of repair. Other large potential customers for more energy-efficient or effective water treatment facilities are corporations, such … Read more
So, now there's even an app for planning your algae oil production.
The Agricultural and Food Policy Center at Texas A&M has a free "Algae Production Conversion Calculator" to help with producing algae crops. The app is free via the iTunes app store. There is also a Web-based version that can be used on Android and other devices.
The app converts between grams per liter and grams per square meter. It also calculates the annual algae oil production possible for a given farm or site based on data that includes pond volume per acre feet, … Read more
The European Union will consider whether a massive wave energy project from Scotland should receive a piece of a renewable-energy and carbon reduction project fund that could total billions of euros.
The Pentland Orkney Wave Energy Resource (POWER) project was nominated this week by the U.K. government for the NER300, a fund managed jointly by the European Commission, European Investment Bank, and member states that's named after the 300 million carbon "allowances" being sold to raise the funds.
If approved, funded, and built, the wave energy farm would be the largest grid-connected wave energy farm in the world, according to the Scottish European Green Energy Centre.
The POWER project as currently proposed would place 24 wave energy converters from Pelamis Wave Power and 10 Oyster 3 wave energy converters from Aquamarine Power in the Orkneys off the coast of Scotland. They would tie in to the Scottish electric grid and, together, they would make up a 28-megawatt wave power farm.
The Pelamis wave energy converter is a floating serpentine machine made up of multiple sealed cylinders that each contain power modules, hydraulic cylinders, and motor generators. The cylinders are connected by two-direction hinged joints. Jostling by the motion of ocean waves in relation to the hinges enables the machine to generate electricity, and transfer it by subsea cable.
The submerged Oyster, meanwhile, is shaped like an oyster shell that opens and closes from wave motion. It uses that energy to pump a hydro-electric turbine back on land to produce electricity.… Read more
Wearables are largely aimed at the person who just wants to maintain a good weight, sleep enough, and maybe get in a little cardio. CNET's Brian Cooley tells you why 2014 could be the breakout year for wearable tech.
