New solar storage solution could be the key to home-brewed electricity

By - November 4, 2009 1 Picture
Reports of new developments in the area of solar power are an almost daily event here at Gizmag. The main focus of research seems to be on improving the efficiency of solar cells, but others are working at developing an inexpensive method of locally storing the energy generated by solar systems. Because society relies on a continuous energy supply and solar energy is diurnal, storage systems are integral to what some see as an inevitable move towards the era of “personalized solar energy”, in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities.

Stealth wind turbines developed to avoid radar confusion

By - November 3, 2009 1 Picture
Plans for the installation of wind farms the world over are being delayed or abandoned due to objections from the aviation community or air defense interests. The problem is that when it comes to low flying aircraft or wind turbines, conventional radar has a bit of an identity crisis - not being able to tell the difference. Recent tests in the UK of "stealth" turbine technology could provide a solution. Read More

3-D photovoltaic systems go where the sun don’t shine

By - November 2, 2009 3 Pictures
The photovoltaic (PV) panels adorning the rooftops of buildings around the world have become a visible sign of the shift towards environmentally friendly solar power. Now researchers have developed a new type of three-dimensional PV system using optical fiber that promises solar generators that are foldable, concealed and mobile, meaning they could be hidden from view and leave rooftops panel-free.

‘Smart Trash’ cash for recycling concept

By - November 2, 2009 1 Picture
If the benefit to our environment isn’t enough to get some people to recycle, Georgia Tech’s Valerie Thomas has come up with the concept of offering a cash incentive enabled by “Smart Trash”. The concept involves a scanner integrated into a trash receptacle that automatically records what is being disposed of using Universal Product Codes (UPC) or radio frequency identification (RFID) tags attached to the trash. This would not only allow recyclers to better sort the waste but could also provide a cash back channel to consumers recycling goods of value. Read More

Japanese solar car wins 2009 Global Green Challenge

By - October 28, 2009 7 Pictures
Japan's Tokai Challenger solar vehicle has taken victory against a strong international field in the 2009 Global Green Challenge. After covering almost 1860 miles (3000km) in four days across Australia's baking red center, the entry from Japan's Tokai University crossed the finish line at 3.39pm local time. The team's run was nearly flawless, reporting only a single flat tire with just over 100 miles of the course to race and the win breaks a string of four consecutive victories by the Dutch Nuon team, which is currently battling it out for second place against University of Michigan Solar Car Team.

Magnetic leaves indicate levels of air pollution

By - October 19, 2009 2 Pictures
Measuring the level of magnetism of tree leaves could be a powerful tool to monitor the air quality of streets. A new study has shown that leaves along bus routes were up to ten times more magnetic than leaves on quieter streets. The magnetism comes from tiny particles of pollution, such as iron oxides from diesel exhaust, that float through the air and either stick to the leaves, or grow right into them. Read More

Solar e-book reader demo from LG

By - October 14, 2009 0 Pictures
E-readers are a welcome alternative to lugging around paper-bound tomes when on holiday, as they can store volumes of reading material in one handy, pocket-sized (well almost) device, and offer users the possibility of hours and hours of uninterrupted reading pleasure. That is, of course, until the battery runs out. LG Display has developed a solar cell capable of extending the battery life of an e-reader, possibly making the anxiety of a blank screen on the last page of that captivating thriller less likely.
