Arnold Leitner
Arnold LeitnerFounder and CEO
Arnold is a clean-tech pioneer. His first company, SkyFuel, re-invented concentrating solar power technology. SkyFuel’s high-precision parabolic trough uses mirror film technology licensed from the National Renewable Energy Laboratory (NREL) instead of glass mirrors and won the R&D 100 Award. It was featured as one of the major clean-tech accomplishments as part of the 40th anniversary of the National Renewable Energy Laboratory. Arnold holds a PhD in Physics from CU Boulder and an MBA from Columbia.
