|Engineers developing ENE-FARM for condominiums
||ENE-FARM is a residential-use fuel cell system that can simultaneously produce electricity and hot water using city gas. It was initially sold exclusively for installation in detached housing. In pursuit of wider diffusion, Tokyo Gas Co., Ltd., developed the world's first such system capable of installation in collective housing. An interview was conducted with personnel actually involved in the work, about the long road of development, which began even before the establishment of installation standards and culminated in the sales launch.
