Big Potential for Zinc-air Cells in Transportation

Written by , on October 22, 2010

A Montana company, Zinc Air, has announced plans to begin commercial producion of zinc-air fuel cells which the company believes could play a significant part in future transportation. Various types of zinc-air cells are possible but mechanical recharged cells offer great potentail for transport. In these, zinc granules are fed into the cells and act […]  Read more »

Floating Wind Turbines More Cost Efficient

Written by , on October 22, 2010

Project Deepwater, a study by the UK’s Energy Technologies Institute, has found that floating wind turbines are more economically efficient than turbines built on offshore foundations. Even though the technology is a little more complex and the inital cost is higher, floating turbines have greater ability to access stronger and more consistent winds in deeper […]  Read more »

Wind Power without Rotating Blades

Written by , on October 19, 2010

A New York design firm, Atelier DNA, has proposed an alternative wind farm concept that uses stalks instead of rotating blades. The ‘Windstalks’ generate electricity when the wind sets them waving. The designers have proposed the idea for the planned city Masdar being built outside of Abu Dhabi. Atelier DNA’s “Windstalk” project is an entrant […]  Read more »

Written by , on October 19, 2010

Mitsubishi Heavy Industries has designed a new energy-efficient container ship which it claims promises a 35 per cent reduction in carbon dioxide emissions. One key features of the new design is a dual propulsion system that the company says would reduce CO2 emissions by 24% compared with conventional container ships. A proprietary air lubrication system […]  Read more »

Big Potential for US Offshore Wind Power

Written by , on October 17, 2010

According to a new report from the US National Renewable Energy Laboratory (NREL), the United States should develop at least 54 gigawatts of offshore wind power. Doing so would provide clean power to high-demand urban centers, generate $200 billion in new economic activity and create more than 43,000 permanent, high-paying jobs. Although the US currently […]  Read more »

5 Gigawatt Solar Park Planned in South Africa

Written by , on October 16, 2010

The South African Government and the US-based Clinton Climate Initiative have completed a pre-feasibilty study on the creation of a "solar park" in Northern Cape Province. The solar park would ultimately generate 5.000 megawatts of electricity and cost $20 billion. Currently, the largest solar park in the world, in California’s Mojave Desert, generates 354 megawatts.
