In 2000, William, who is loosely allied with Solar Household Energy, Inc. as one of that organization's roster of solar entrepreneurs, returned to Germany for another course of study. On his return, a larger scale business plan was developed - one that would create a proper workshop and permit a number of employees to be used in expanding cooker production. It was the beginning of ISOMET. Mr. Ilboudo and his workers have installed a solar bakery capable of producing 1500 loaves of bread a day. The bakery is equipped with a 16 sq. meter. Scheffler reflector, and has a heat retention system using a container filled with stones.
