Photo Grid offers a dead-simple way to create collages with up to nine photos from your mobile device. It may not be the most powerful app in the world, but it certainly offers most of the customization options you need to make a variety of beautiful collages.

Right when you open the app, Photo Grid asks you what kind of collage you want to make. Choices include Free form, Single photo, Grid (predesigned templates), High (photobooth-style vertical strip), and Wide (horizontal strip of portraits). Regardless of the type you choose, Photo Grid makes it easy to swap photos within, zoom, … Read more

Anonymous has so far plied its trade in "hactivist" exploits. But according to the director of the National Security Agency, it might soon turn its focus to U.S. infrastructure.

According to the Wall Street Journal, citing sources, Gen. Keith Alexander has said in private meetings at the White House and elsewhere that the U.S. must keep a close eye on Anonymous' growth. He reportedly warned that if the organization continues to gain power, it might even take down a part of the U.S. power grid within the next couple of years.

How serious might such … Read more

Electric carmaker Coda Automotive thinks its car batteries are versatile enough to buffer the electric grid.

The company today announced a venture called Coda Energy, a business unit created to build stationary energy storage systems.

The expertise Coda acquired in designing lithium ion batteries for electric vehicles translates directly to the grid energy storage world, the company said. Its battery system includes an active thermal management to keep batteries at a safe temperature and it has a manufacturing partnership with Lishen in China to make products at large scale. It plans to make modular energy storage systems that can be … Read more

Eos Energy Storage is developing a zinc air battery it claims will be able to clear up bottlenecks on the power grid by placing them at office buildings and shopping malls.

The energy storage startup before the end of March plans to close a round of funding from corporate partners which is expected to be at least $5.5 million. It plans to raise $20 million by the end of this year and start making its batteries at a pilot manufacturing facility next year, said President Steve Hellman.

Although it doesn't have a product on the market yet, Eos … Read more

Creating collages with your images is easier than ever on your iPhone, and--with the right app--you can make great looking projects in minutes and share them immediately.

Are you old enough to remember making collages with a glue stick and poster board? These days anyone can create a collage (without all the mess) using digital photos and any photo layout program on a desktop computer. But some recent apps for iPhone make it even easier with intuitive touch-screen controls and other extras that put the old glue-stick-and-photo method to shame.… Read more

Speedy lithium ion batteries, the power source for consumer electronics and electric vehicles, are making inroads into the renewable energy business.

A123 Systems today announced that a Hawaiian wind project developer will use its batteries to firm up power delivery into the grid. The Auwahi Wind project, which has a generating capacity of 21 megawatts, will be buttressed by a giant battery bank able to deliver 11 megawatts of power.

It's the second time this year that A123 Systems' storage systems, built around shipping container-size battery banks, were chosen to be co-located with a wind farm. The Laurel Mountain … Read more

The time has come for the U.S. government to focus a single agency's efforts on reinforcing the security of the electrical grid, MIT researchers said today in a wide-ranging report.

The issue, MIT's researchers say, is that the many stakeholders involved in maintaining the U.S. electrical grid aren't working together, even though "cybersecurity regulations for bulk power systems already exist in the form of the NERC Critical Infrastructure Protection reliability standards." For one, the researchers point out, those standards only apply to "the bulk power system and [do] not include the distribution … Read more

By storing solar energy in molten salt, BrightSource Energy can now build one less solar power plant.

The company said today that it is adding energy storage to three planned solar projects that will supply power to utility Southern California Edison.

Instead of building seven power plants to provide about 4 million megawatt-hours per year, BrightSource now expects to be able to meet that with six concentrating solar plants to be built over the next six years, including three that will have storage. It is now constructing its first project, the Ivanpah Solar Electric Generating System, which will not have … Read more

While consumers may simply crave longer-lasting batteries for electronic gadgets, the holy grail for many material scientists is batteries that can pump power into the grid for hours.

Stanford University researchers today detailed a new electrode material they claim holds promise for grid storage batteries that can work 30 years without a dramatic decline in performance.

In the lab, the copper and iron-based nano-engineered material was able to take 40,000 charge/discharge cycles while still maintaining an 80 percent capacity. By contrast, the lithium ion batteries used in consumer electronics degrade noticeably after only a few hundred cycles.

The … Read more
