Micro-bubble dishwashing machine 80% less energy

“One of the inventions is a dishwashing machine with ultrasonic micro-bubbles that can reach the smallest crevices in the utensils, and make sure they emerge spotlessly clean. Edwin Siew, final-year student, Singapore Polytechnic, said: “In between the fork, there are crevices that the conventional dishwasher cannot hit because the spray jets are not angled at a specific point and hence, the crevices are not cleaned.
“But in our ultrasonic dishwasher, as long as the fork is submerged, and fully inside the water, the ultrasonic waves can hit and clean the fork effectively.” The invention uses 80 per cent less energy than conventional dishwashers, and gets the job done in eight minutes instead of the usual 15 minutes.
The dishwashing machine does not require hot water, and consumes only 2.8 kilowatts of energy, compared to the average consumption of 12 kilowatts by a conventional dishwasher.” – Full Article Source
