The SkyTrough parabolic dish at NREL's South Table Mountain test site uses a reflective laminate over lightweight sheet metal to focus the sun's energy. The technology now being scrutinized by NREL engineers could make concentrating the sun's heat to generate electricity more efficient and affordable. "It's unlike any parabolic trough design used so far," says senior engineer Keith Gawlik.
Most drivers don't have a clue about the percentage of free glycerin or Group I and II metals in the biodiesel they are pumping into their tanks, and they don't have to. New biodiesel standards developed with NREL's help should boost confidence in fuel quality and support from vehicle manufacturers. NREL research provided the technical basis for setting the new standards.
