Interview with two students from Principia ( a school from Midwest USA with only about 500 students and no engineering department) about their solar car Ra 7s. Their Ra 7s is a modified version of their previous Ra 7; main change from Ra 7 is from gallium arsenide PV array to silicon PV array. The main focus is to make the most compact, aerodynamic, and efficient car they could. This footage was filmed by Michael Nunamaker and interviewed and loaded (made available) by Susan Sun Nunamaker of Sun Is The Future at sunisthefuture.net Any questions, concerns, comments, and suggestions are welcomed at sunisthefuture@gmail.com Let’s work together in speeding up the process of renewable and solar energy.
