The desert planet of Arrakis, Dune, is a ball of desiccated sand, a place where water is more precious than gold. Wait, no, we’re talking about Australia. Or Dubai. The EVOLUTE toilet concept is designed for parched climates and uses 90 percent less water than conventional toilets.

The toilet ditches the conventional water tank and instead uses a rotating sphere and miserly jets of water. The sphere sits at the base of the bowl. It has a small cup to catch your stuff. Hit the flush and the sphere rotates and dumps the waste down the sewer drain. A small jet of water rinses out the cup and washes down the walls of the bowl. The whole thing is mechanical–no electricity required. It uses less than one liter of water per flush and takes up 30 percent less floor space than a conventional toilet.

It’s a clever design and should be on the market sometime in 2012. But really, I just wanted to mention Arrakis.
