The bicycle helmet you all have been waiting for is here: the green helmet. From the tutorial:

I thought this would be a well-suited application of solar powered trickle charge panels. I only ride at night about an hour a week, so during the day the helmet can sit in a window and charge. Helmet mounted lights also free me from having lights mounted on my bike that need to be detached to keep from being stolen. It works in the rain and so far is always charged when I need it.

When you have completed your helmet, check out the world’s most friendly bicycle cities. And our very own state of Colorado is in the list!
