Baobab / oxygen concentrator

Living in a large city is stuffy and desolate. The cars on the road emit fumes everyday and people are push around in a crowded street. It is always a long hope to enjoy the cool breeze in the peaceful forest for those who are burdened in urban-busy life. However, it is not easy to find out the place like that in a metropolitan. BABOAB supplies the oxygen to those people by the electrolysis reaction from the water, using photovoltaic power generation. The oxygen leads the people feel fresh, as well as helps them to clear their heads.
