Sevin Coskun, a Turkish inventor winner of the Green Gadgets 2008 competition, proposes a hybrid between washing machine and toilet to get us to consume less water.
Your Washup, as we see in the image, bases its operation on connecting the water outlet and inlet of the washing machine and toilet respectively, with which all the water that is currently wasted when washing, would be used when flushing.
The idea seems good, although as it is presented in the image of the prototype, we can easily come to the conclusion that the collation of the washing machine in that position is not the best or the most comfortable. The washing machine does not necessarily have to be on top of the toilet for this idea to take place. They can be connected through an intermediate tank to store water, so that everything is more natural in use.
