Koizumi 'Best Design Award (internet voting)' winner - 23rd Koizumi lighting design competition - In Colombia, due to the lack of public lighting, the busy beaches become abandoned and dangerous at night, as the electric network cannot be channeled to the beach. The constant prevailing wind on the coast is an ideal source for lighting. My design is a self maintaining public lighting system for the coasts of Cartagena based on the principle of vertical wind power plants, and it is made of bamboo.
