He was influenced by Gandhi, among other people. Gandhi had done a lot of work on appropriate technology, like on charkhas (hand-operated spinning wheels), khadi (indigenous handloom cotton fabrics), in India, with a view to self-sufficiency of the people, apart from (but also related to) his more well known work on the non-violent feeedom movement which resulted in India's independence from Britain.

Such work started decades ago. If people research what has been done in their fields in the past, they can sometimes avoid rediscovering or reinventing a lot of wheels.
