Renewable Energy

A dish-shaped mirror focuses sunlight onto a glass ball, which distributes it evenly onto ...

Borrowing technology from sophisticated telescope mirrors as well as high-efficiency solar cells used for space exploration, a group of students and researchers at the University of Arizona are putting the final touches on a novel power plant that promises to generate renewable energy twice as efficiently as standard solar panel technology with highly competitive costs and a very small environmental impact.  Read More

Ontario's Green Sun Rising has launched a Solar Bench that provides some welcome relief from the heat of the sun for mobile device users, while also offering to keep batteries topped up via flexible solar panels installed on the roof.  Read More

Currently, land-based tower wind turbines are the dominant source of wind power, but they take up a lot of space and generally need to be placed in high visibility areas, such as the tops of hills or ridges. They are also located close to the ground, where friction from the Earth’s surface slows the wind and increases its turbulence, negatively affecting the efficiency of the turbines. NASA engineers are looking at technologies that would help airborne wind power systems, capable of generating much more power, get off the ground.  Read More

Two-faced solar cells boost yields by up to 50 percent

Israeli photovoltaics developer bSolar has developed a double-sided solar cell it claims can boost the energy yields of solar panels by up to 50 percent when installed vertically, or by between 10 and 30 percent in more typical installations. The "bifacial" cells rely on a back surface field (BSF) of boron rather than aluminum, which bSolar claims not only allows for an open rear face but also increases the efficiency at the front of the solar panel.  Read More

SiGNa Chemistry has received funding from USAID to develop portable hydrogen fuel technolo...

SiGNa Chemistry, a company developing portable hydrogen fuel technology, is close to taking one of its solutions to market. Hydrogen is an emissions-free renewable source of energy – however, logistic obstacles related to current considerations such as high-pressure tanks, and metal and chemical hydrides, have stymied its progress towards the mass market.  Read More

It's rare to see a building's form so adapted to maximizing renewable energy potential as is the case with the Endesa Pavilion, Solar House 2.0. Not content with a roof completely covered in photovoltaic panels, the designers at the Institute for Advanced Architecture of Catalonia (IAAC) led by Rodrigo Rubio have covered the building's south facade with protrusions supporting additional solar panels, which are angled optimally for harvesting energy from the sun.  Read More

In a bid to mitigate the risks associated with fuel transportation and to make soldiers’ work less technically complex, U.S. military scientists have started to test microgrids that would provide clean energy to soldiers in the field. Since 2009, scientists from the Communications-Electronics Research, Development and Engineering Center (CERDEC) have been developing two systems – RENEWS and REDUCE – which are being tested at the Fort Irwin National Training Center in California, and by U.S. Africa Command.  Read More

Remember the Airborne Wind Turbine covered by Gizmag towards the end of March? The creator of the prototype, Altaeros Energies, has been in touch to show us a video of the prototype in operation and we can confirm that a) it flies and b) the turbine goes round.  Read More

Solar Impulse flying at the Paris Air Show in June 2011 (Photo: Solar Impulse)

After its successful inaugural Paris-to-Brussels flight last year, the Solar Impulse solar-powered aircraft will attempt to fly all the way to Morocco in May or June of this year, a journey almost ten times the distance, and its furthest flight and as a close as it has yet come to a trial run of its round-the-world flight planned for 2014.  Read More

Altaeros Energies have created a floating wind turbine that produces low cost, renewable e...

Altaeros Energies has announced the first testing of its Airborne Wind Turbine (AWT) prototype that resembles a sort of blimp windmill. The test took place at the Loring Commerce Center in Limestone, Maine, USA where the AWT floated 350 feet (107 meters) into the sky and successfully produced power, before coming back to earth in a controlled landing. The turbine was deployed into the air from a towable docking trailer, while demonstrating that it can produce over twice the power at high altitudes than generated at conventional tower height  Read More
