Abstract

• The idea for this invention emerged when we visited the city of Tijuana. By observing and walking through Rancho Las Flores we noticed that this community had many needs. Poor communities in underdeveloped countries are often faced with the challenge for a better life. Many of them lack the economic means to have a better way of living. The location of this community is in the marginal areas of the city. The lack of basic services has forced them to improvise, by taking materials that are readily available they are able to come up with the most amazing and ingenious inventions. So we wanted to try it.
