Intel's annual International Science and Engineering Fair kicked off this week in Atlanta, showcasing over 1,500 high school students in what is the world's largest pre-college science competition. Students, representing 51 countries, have come in with their projects on engineering, science, robotics, medicine, physics, electronics, and the list goes on!
They are competing for almost $4 million in scholarships and awards. A good portion of the projects exhibited relate to sustainability and the environment, and Intel was kind enough to send us down to meet with these young EcoGeeks. The list below shows all of the projects we've covered from the fair so far.
These projects are amazing from any perspective, but the fact that these EcoGeeks are a decade younger than me (and I am quite young) really shows that innovation knows no bounds.
