The Sustainable River Transport (Spanish: Transporte Fluvial sustentable – TFS) was created in 2010 by Alexander Wopper, a German sailor, ship operator and businessman who has lived in Chile for 30 years.
The aim is to show tangibly, especially to the young entrepreneurs, that through the use and application of the most innovative and currently available technologies on the market, it is possible to develop a sustainable and environmentally friendly business model.
The TFS is composed of the Barrio Flotante, the headquarter of the solar taxis. This place has a restaurant, a small square, offices, a shop and service areas. All self-sustaining through the use of solar panels on the roofs to generate electricity. The water supply is obtained through the river water purification by reverse osmosis systems. These are aquatic plants that allow the purification of gray and black water, and also solar heaters to obtain hot water.
Solar taxis, an icon of the river, are designed with the highest-engineering standards to make them highly efficient hydrodynamically. They have solar panels on the roofs to capture solar energy, which is stored in banks of deep cycle batteries, and power electric motors by inverters for propulsion.
