Firstly, I am very, very expensive. In 2007, it was purchased new toilet for the International Space Station ISS the modest sum of $ 19 million, almost 14 million €. This technological gem is mounted in the enlargement of the station in 2009. The old system of disposal of organic waste had shown signs of slowing down, so that between May and June 2008, astronauts dovunti are staying two weeks with the toilet not functioning due to lack of a spare, almost as it happens in our homes! In fact, the toilet has stopped working and the many attempts to repair have been all in vain. The only solution was to do with sending a new one from the ground. But how does this space toilet?
Unlike previous models, this, if nothing else, it looks like a toilet, a door opens onto a secluded niche where gaming is not a cup is quite different to those we are accustomed. Of course, in the absence of gravity sit on the toilet is not so obvious here and then explained the presence of specific "belts security "fit for purpose.
The drains of the toilets are kept at a pressure slightly lower than that of the external environment in this way the products are sucked physiological and stored in watertight containers. Here begins a sophisticated purification process that has as its ultimate goal to turn urine into drinking water
