Cast a Vote in the Greener Gadgets Competition

Of the top fifty submissions, one that caught my eye was the E-Tree Book, an educational gadget that teaches kids about energy by giving them a set of lessons and activities on energy-related processes, from photosynthesis to rechargeable batteries. Another entry, from a designer in Bogota, Colombia, uses the model of a traffic light to present the public with simple data about local environmental conditions. The project is developed on an open source network that invites others to contribute their own ideas for new ecological signals.

Check out all the designs and cast a vote! Inhabitat and Core77 will be announcing their winners after the conference on February 27.
