It's a joke. The point being that dishwashers have to use more water and energy because breaking glass is the bottleneck of how hot and pressurized the water can be. The joke is that startup founders ignore tradeoffs and are trying to make an impossible product while marketing it as soon solved. Like "we found a way to increase voltage with no increase in watts! We are just trying to work around the decrease in amperage..."
I’ve seen laundry setups where the water is ozonated, and no detergent (or hot water!) is required to remove debris and oxidize oils and other gunk out of clothes.
