Imagine having a washing machine that only needs one cup of water for a full wash. That may not be so far away since researchers at Leeds University in the UK are already working on it. Xeros uses thousands of 1/2cm plastic chips to absorb and hence remove dirt. When the water heats up, about 20 kilos of chips are added to the water and detergent. The chips can be used up to 100 times, about 6 month’s worth. The team is hoping to bring the prototype out to the public by 2009. The scientists say that it could save billions of gallons of water a year, not to mention how it would cut down on your electric bill.
