The washing machine that uses only a cup of water

I read about this invention very recently here
washing machine that uses only one cup of water http://bit.ly/q1Eoi

So, well, To cut the long story short,
This washing machine still uses electricity for its operation, so it is not one of those magic washing machines that run on nothing.
Guessing from the description I am guessing they don't use any detergent per say, but then they use beads-a load full each time in lieu of detergent and water.
But the thing is, these beads , they are a certain type of plastic, which when slightly moistened, tend to gain the property of attracting and gathering up dust, much like soap does, but well, for a loadful of beads, only a cupful of water is enough to moisten them and convert them to an amorphous form
This amorphous form is what is active in making clothes clean.
The best part about these beads is that these beads can be reused.After the tumbling and cleaning action, the beads get collected out seperately by the machine for most part.And these beads can be reused for upto 100 loads, which is fairly fine given the fact that , these beads saves us 100 loads of detergent used and also hundred loads of water used.
Saving water is such a great priority these days. After all , drinking water is a valuable resource and the lesser we can get by with using the better.
I think this washing machine is going into commercial production in a couple of years in North America.Good!
