 MONTPELIER, Vt. (AP) - Chris Fitzhugh spent spring break building a copper and PVC-pipe model to show how temperature differences in the ocean can be used to generate electricity. It's not just a personal quest.
The 17-year-old junior from Peacham and his teammates — two in Mexico, one at St. Johnsbury Academy — were competing in the Global Challenge, a Vermont-based contest aimed at improving American high school students' math and science skills.
During the school year, 58 teams of American students coupled with students from China, India and Japan tackled technological solutions to global warming. They chatted online, divided jobs based on skill, consulted with advisers, and in the final grueling weeks, wrote a professional business plan.
