Washing machine that used 90% less water than conventional machines!

Developed by researchers at Leeds University, the machine is about to go to market in the US market. The developers have established a spin-off company called Xeros Ltd to market the technology. The name means 'dry' in Greek, apparently.

The company is looking to licence the technology to machine manufacturers says the Xeros Ltd CEO, Bill Westwater.

Once it has established itself in the commercial sector they aim to target the technology at the consumer market.

The technology uses reusable polymer (nylon) beads with only a beaker of water and a drop of detergent and works by absorbing the dirt into the beads themselves. The machine automatically remove the beads from the load at the end of the cycle and don't require cleaning, lasting for about 100 washes. Additionally, no spin cycle is needed and so the machine saves energy and water, which helps to significantly reduce CO2 emissions by abut 40%.

If the machine replaced existing machines in the US, thi would mean saving of 1.2 billion tonnes of water saved per year, equivalent to 17 million swimming pools and a carbon saving equivalent to taking 5 million cars off American roads.
