Some news updates from the world of TreeHugger (http://www.treehugger.com/)
A 12 year old boy was told to participate in the school science fair and ended up constructing a new type of solar cell!
3D Nanotube Solar Cell For Visible & UV Light
From his Davidson Institute Award submission,
In his project “A Highly-Efficient 3-Dimensional Nanotube Solar Cell for Visible and UV Light,” William invented a novel solar panel that enables light absorption from visible to ultraviolet light. He designed carbon nanotubes to overcome the barriers of electron movement, doubling the light-electricity conversion efficiency. William also developed a model for solar towers and a computer program to simulate and optimize the tower parameters. His optimized design provides 500 times more light absorption than commercially-available solar cells and nine times more than the cutting-edge, three dimensional solar cell.
That's a quote from the article, http://www.treehugger.com/files/2008/09/william-yuan-invents-3d-nanotube-solar-cell.php. It's so cool! It's amazing what a little bit of work and creativity can do to save the earth, dont you think?
Also, wouldn't you like to save $1 billion USD annually? I know I would.. Then maybe I can buy an eco-jet and fly to Paris for my sixteenth. Well, it turns out that LIGHTER ROOFS can save huge amounts of money.
The world is in danger, we need to be its superheroes.
Love,
