Over at Texas A&M University - Kingsville, students there were showing off some of the high tech concepts that could boost renewable energy.They built four wheel gizmos that are being run with the help of solar power, wind and water sources.The event, which is sponsored by the Texas A&M University - Kingsville Robotic Club, pitted team against team as they battled to see who could be the fastest to raise a flag using those robots.For the students, Monday was the culmination of two long semesters of study."We logged plenty of hours. Building, constructing it, coding, trouble shooting it. We just went to competition in Oklahoma a week ago. We ended up placing sixth," says TAMUK student Juan Guardiola.By the way, at that competition the students from TAMUK actually placed third through sixth, a sure sign the engineering program there is on the rise.
