Claim: An alternative approach is exemplified by the Scheffler Reflector, named after Wolfgang Scheffler (Special Recognition Awardee at the 2006 Nuclear-Free Future Award) a paraboloidal mirror which is rotated about axes that pass through its centre of mass.
Evidence: An alternative approach is exemplified by the Scheffler Reflector, named after its inventor, Wolfgang Scheffler. This is a paraboloidal mirror which is rotated about axes that pass through its centre of mass, but this does not coincide with the focus, which is outside the dish. Scheffler was born in Innsbruck, Austria, and received the Special Recognition Award at the 2006 Nuclear-Free Future Award.
