We earlier covered a 1959 newspaper article speculating on a future with ultrasonic dishwashers. That it would seem is old hat. Here is another newspaper clip from 1958 talking about ultrasonic washing machines and dryers!
It is almost surprising that the limitations back then remain to this day. The column notes that the main barrier is cost. This aspect hasn’t changed one bit. Based on our current understanding of physics an ultrasonic washing machine will be more trouble than what it is worth. Nevertheless, we hope for some new scientific discovery to make it simple and affordable.
