The use of renewable resources instead of fossil fuel has recently seen an upwards trend. The prototype created by the students aims to obtain energy from the water gathered on roofs, which are designed in the shape of an ‘M’ to collect as much rain as possible, to optimise hydroelectric resources. It was suggested that this energy resource should be disseminated in the regions with high levels of precipitation. Whilst this project can be obtained with an economical cost, regulating the speed of the water flowing from the roof is difficult. Overall, though, since the energy produced can be stored, the usages of this kind of roof should be increased and these stations should be integrated with other renewable energies, such as wind, tidal waves, etc.
