Dishwasher using superheated steam is more effective and energy efficient

At present, the researchers have only modelled a simple steam dishwasher that cleans a single plate — whereas a commercial version would need to clean multiple items at once.

However, while this would take longer than just 25 seconds, the team have said that the concept should be much faster and more efficient than conventional, water-based machines.

The initial costs of a steam dishwasher would also be higher than their regular counterparts, but would pay off in the long run thanks to needing less water and electricity to run — not to mention eliminating the need to buy detergent.

The concept, the researchers said, would be ideal for use in hotels, hospitals and restaurants, where high standards of hygiene must be met.
