British inventors have designed a washing machine that takes eco-friendliness to a new level: it uses just a single cup of water to wash a load of clothes. Instead of water, the Xeros machine uses special plastic chips in each wash, and when that single cup of water is heated, these chips absorb the dirt -- including tricky stuff like coffee and lipstick. Though it's still in prototyping, the inventors are intending to commercialize their machine, and it may even hit the shops next year for a price similar to conventional machines.
