San Diego residents can feel particularly warm and fuzzy this festive season as their Purdy Farm Christmas trees have been lovingly trimmed and lit up via solar power. In what is believed to be a world first, Stellar Solar's Mobile Solar Station has been contracted to power the Purdy Farm Christmas tree lots in Del Mar, Carlsbad, and San Diego. The Mobile Solar Station is being used to power the compact fluorescent lights (CFL) on the lot perimeter and the electric chain saws used to trim customer's trees.  Read More

It’s not often that you hear about an invention that was modeled after bird poop, but there’s a first time for everything. In fact, this fecally-inspired device could ultimately be responsible for reforesting billion of acres of parched land, and it just won Popular Science’s Best Invention 2010 award. It’s called the Groasis Waterboxx, and it’s a low-tech product that helps seeds or saplings grow into strong trees in eroded, arid and rocky environments.  Read More

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

Researchers at the University of Washington (UW) have taken the term ‘green power’ literally by running an electric circuit from the power generated by trees. Sure, there isn’t much electrical power to harness, but the researchers say it should be enough to run wireless sensors that could be used to detect environmental conditions or forest fires and could also be used to gauge a tree’s health.  Read More
