Australia to get Southern Hemisphere's largest solar PV plant

By - July 31, 2013 4 Pictures
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

California to get America's fastest high-speed rail line

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).

Opinion: Are "school of fish" turbine arrays a red herring?

By - July 23, 2013 7 Pictures
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.

ARES system to put energy storage on the right track

By - July 22, 2013 6 Pictures
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.

Crowdfunded solar-powered classroom leaves the grid

By - July 5, 2013 3 Pictures
Aaron Sebens and his class of fourth-graders from the Central Park School for Children in Durham, North Carolina hit Kickstarter back in March to try and raise enough money for their classroom to go off-grid. A rather modest target of US$800 was smashed within a day by the kindness of the international community and, at campaign end, the kids found themselves with the handsome sum of $5,817 to spend on the purchase and installation of a roof-mounted solar energy harvesting system. A wind turbine was added to the shopping list, and just two months later, the 208ers threw a huge "Flip the Switch" party to celebrate leaving the grid. Sebens reports that the classroom has been running on renewables ever since. Read More
