The present project is about making the toilet more water efficient. Standard toilets use 15 times more drinking water per day than a human does. The proposed concept is a toilet based on the waste separation principle. Considering that each type of human waste requires different amount of water to be flushed away, the new toilet adapts to male urination, female urination and defecation, discharging the right amount of water for each one of them. The new design integrates a male urinal and a separating bowl; both of them are water saving solutions which combined will reduce water consumption in toilets by up to 60%.

A study on the use of the Afsluitdijk (or more generic, enclosure dams in general) for the generation of energy. Focus in this study in on solar panels on the dike.
