Advanced offshore buoys help study wind energy potential

By - October 30, 2014 3 Pictures
Offshore wind power in the United States is nowhere close to meeting the potential this renewable energy form has to offer. There are a myriad of reasons why, including lack of information on energy-harnessing possibilities at specific sites. The US Department of Energy’s Pacific Northwest National Laboratory (PNNL) is looking to change this, by dropping two very advanced data-collecting buoys into coastal waters. Read More

Electrodialysis identified as potential way to remove salt from fracking waste water

By - October 26, 2014 2 Pictures
Fracking is a highly controversial and divisive issue. Proponents argue that it could be the biggest energy boom since the Arabian oil fields were opened almost 80 years ago, but this comes at a serious cost to the environment. Among the detrimental effects of the process is that the waste water it produces is over five times saltier than seawater, which is, to put it mildly, not good. A research team led by MIT that has found an economical way of removing salt from fracking waste water that promises to not only reduce pollution, but conserve water as well. Read More

Ear-IT project: How listening to the sounds of a city could make for smarter living

By - October 23, 2014 1 Picture
As the Internet of Things starts to take hold, we're seeing the emergence of gadgets equipped with all kinds of sensors to improve the world around us, from energy-saving climate control systems to smart locks for the front door. But have you ever thought about how sound might be measured and used to bring another level of automation? For the last two years, the Ear-IT project has been monitoring acoustics in the Spanish city of Santander, and says the results could improve the lives of its residents in ways ranging from improved traffic flow to energy savings in the home.

Lockheed Martin announces it's working on a compact fusion reactor

By - October 16, 2014 4 Pictures
Fusion reactors are a bit like buses; you wait forever for one, then two come along at once. No sooner does the University of Washington announce that it’s working on a breakthrough compact fusion reactor (CFR) than Lockheed Martin says that its Revolutionary Technology Programs unit, AKA the Skunk Works, in Palmdale, California has one that could be ready for market within ten years.

Heat-energy storage device could make household solar power more feasible

By - October 15, 2014 1 Picture
Although solar panels are active while the sun is shining, they typically don't do much once the sun goes down. This is why some systems incorporate water tanks. The water is heated during the day via the panels, then that stored thermal energy (heat) is used to warm the home at night. While the tanks are effective, they also take up a lot of space, making them difficult to fit into peoples' homes. A newly-developed device, however, stores just as much heat in half the space – using paraffin instead of water. Read More

University of Washington fusion reactor promises "cheaper than coal" energy

By - October 12, 2014 1 Picture
In the 21st century, the world lives with two futures ahead of it – one of looming energy shortages, and another of godlike energy abundance. The key to this whether it’s possible to turn fusion reactor technology from a laboratory exercise into a real-world application. Engineers that the University of Washington are working on a fusion reactor that, when scaled up, could produce energy on a practical scale, yet at a cost rivaling that of a conventional coal-powered plant.

MIT's improved all-liquid battery could make renewable energy more competitive

By - September 24, 2014 2 Pictures
Our ability to store energy has proven a big hurdle in the adoption of renewable energies. But now a team of researchers from MIT has developed a new all-liquid battery system that extends the life of such devices while also costing less to make, a development they say could make wind and solar energy more competitive with traditional sources of power.
