The award was received from the Solar Energy Society of India (SESI), a member of the International Solar Energy Society (ISES). "Like all pioneering work, initially the path had been a slow, up-hill process," said the Gadhias. "But now, due to ever-increasing energy costs and environmental catastrophes like global warming, it makes mankind realize that clean, renewable, sustainable technologies are the best possible option." Upon winning the award, the Gadhias acknowledged Dr. Dieter Seifert and Wolfgang Scheffler, whose solar concentrator cooking technologies are promoted by Gadhia Solar.
