Interesting. “It’s counterintuitive—because more often than not, the technological solution is worse than the analog one—but washing dishes by hand actually uses around twice as much energy, and way more water, than the most efficient dishwashers on the market. And this tiny new dishwasher prototype uses even less water, and no electricity at all.

“The dishwasher is free from dependence on infrastructure,” says Israeli designer Chen Levin. Instead of plugging in, a hand crank on the side provides power for jets of water. A tablet made from sodium acetate heats the water up without electricity. The system takes only a minute to clean dishes, Levin says.”
