From 11 to 22 June 2018, a team of 17 NTU students embarked on Ecoventure 2018 to Ban Lad Kuem, Oudomxay Province, Laos to install solar panels, conduct enrichment programmes and introduce a social entrepreneurship programme in the village. The social entrepreneurship programme proposed to the village was intended to provide light to homes in Ban Lad Kuem through a rechargeable powerbank rental system. The team provided 4 sets of powerbanks attached with a USB LED light each to be used as a portable light source at home. In this way, each household could rent a set from the primary school at a small cost and once the powerbank was depleted, they would return the entire set to the primary school. The principal or school teachers would recharge the powerbank with the solar power harvested by the panels and the set could be rented to another family subsequently. Money earned from this social enterprise would be managed by the primary school principal and used to maintain the solar panel in the long run or to replace faulty parts if required.
