More recently he analyzed the effects of solar heat on water and the practical implications for utilizing solar power. His achievements were recognized by many honors including the Rothschild Prize (1966). After retiring from the Technion, the eternal young man spent two more decades at the Weizmann Institute, where he led research into the production of hydrogen-free fuel using solar energy.
