Researchers at Harvard have developed an inexpensive, high capacity, organic battery that uses carbon-based materials as electrolytes rather than metals. The researchers say the technology stands to be a game-changer in renewable energy storage by solving the intermittent generation problems faced by renewable sources, such as wind and solar. The battery offers large volume electricity storage not possible with solid-state batteries and at a fraction of the cost of existing flow battery technology.  Read More

Biocrude produced using the new process

Engineers at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) have created a continuous process that produces useful crude oil minutes after harvested algae is introduced. This new process does not require drying out the algae, which grows in water, saving time and energy that would be otherwise wasted. The final product can be refined into aviation fuel, diesel, or gasoline.  Read More

Gizmag's pick of the 10 coolest high tech toys

Christmas is just around the corner and the hunt for the best kids toys out there has never been more exciting. With iPhone-controlled toys, customizable robots and smart toys that aim to teach kids life skills while entertaining them, the latest breed of high-tech toys have a lot to offer. Even books and pens, augmented with a little technology can read to kids or coach them to write. If you're looking to surprise junior with toys that feature a delightful technological twist, Gizmag's top 10 coolest tech toys for kids should give you plenty of ideas.  Read More

Spectrolab has set a new solar cell efficiency record of 38.8 percent for a ground-based multi-junction solar cell. The new world record doesn't exactly smash the previous mark of 37.8 percent, which was also set by Spectrolab, but is welcome news in a field where every percentage point counts.  Read More

MIT's high-performance membranelss flow battery could be used to store green energy for th...

Researchers at MIT have come up with a new design for a rechargeable flow battery that does away with the expensive and ineffective membrane of previous designs. The device could prove the ideal solution for effectively storing energy from intermittent power sources such as solar and wind power.  Read More

The Nyngan solar PV plant will be the largest in the Southern Hemisphere

With plenty of sun-drenched, wide open spaces, Australia is an obvious place for large-scale solar power plants. It would seem that large reserves of coal, oil and natural gas, have on the other hand made it difficult for the country to wean itself off fossil fuels. But renewable energy is getting a boost down-under with the announcement of two solar projects, one of which will be the largest solar photovoltaic (PV) plant in the Southern Hemisphere.  Read More

An artist's impression of California's new high-speed train

When people grumble about how they think the US isn’t as technologically advanced as it should be, they like to bring up bullet trains – Europe and Asia have them, so why doesn’t America? Well, it’s getting one. Work is starting this summer on a high-speed rail line running from San Francisco to Los Angeles, that will carry a passenger train traveling at over 200 mph (322 km/h).  Read More

The battery is designed to even out power from renewable sources such as wind (Photo: Jon ...

Europe's largest battery is to undergo testing in the UK, where it will be used to store and regulate energy generated from renewable sources such as wind and solar power, The Guardian reports. The lithium manganese battery, developed by S&C Electric Europe, Samsung SDI and Younicos, will be capable of storing up to 10 MWh of energy.  Read More

John Dabiri has hypothesized and tested counter-rotating arrays of vertical axis wind turb...

Since we first looked at John Dabiri's hypothesis that vertical axis wind turbines should be arrayed like a school of fish to reduce the land area required for wind farm installations, the MacArthur Genius Grant recipient has continued to work on the idea. Following the latest round of coverage, Gizmag takes a deeper look at his concept, and wonders whether the idea of packing turbines into as tight a space as possible might overlook some wind energy fundamentals.  Read More

The ARES system uses electric locomotives as a form of energy storage

We’ve recently looked at ocean-based energy storage system concepts from MIT and Subhydro AS that are designed to overcome the intermittency problems of renewable energy sources like wind and solar by pumping water out of large tanks and using gravity to let it back in and generate electricity when needed. Santa Barbara, California-based company Advanced Rail Energy Storage (ARES) has come up with a land-based alternative that would provide grid scale energy storage using electric locomotives.  Read More
