Eco-friendly dishwasher uses superheated steam instead of soap to clean dishes

New dishwasher technology could soon save you money on water, electricity and detergent, a study reveals. Researchers have performed simulations of a dishwasher system that uses superheated steam instead of soap to clean dishes. Superheated steam is an extremely high-temperature vapour generated by heating the saturated steam obtained from boiling water. Results of computer simulations suggest that such a dishwasher would be able to kill 99 per cent of bacteria on one plate in just 25 seconds. As yet, the dishwasher only exists as a computer model, and not a physical object, but researchers say their study provides a basis for the development of next-generation dishwashers'.
