Al Lewandowski has over 30 years of experience in the solar field. For a majority of his career he worked at the National Renewable Energy Laboratory on various solar thermal technologies but focused on concentrator optics for most of that time. He was responsible for the design of the High Flux Solar Furnace and the R&D efforts there to investigate new high temperature, high flux applications. These applications included the demonstration of optical techniques to generate up to 50,000 suns, production of fullerenes at temperatures greater than 3000oC, high temperature chemical reactions to produce hydrogen and testing of many new power production technologies. Al retired from NREL in 2006 to work in industry (both CPV and parabolic trough companies) and now works as a consultant on optical design, analysis, and testing of solar concentrators.
