Sometimes simplifying tech is the best way to improve it. A concept dishwasher shown at DMY International Design Festival proves just that. Colo, designed by Peter Schwartz and Helene Steiner, modifies your existing sink and turns it into a dishwasher...
Dirty dishes are placed within a tray that then is put into your sink.
A cover, attached with a hose to your faucet and featuring a basic water jet system within, is placed over the sink.
Once dishes are cleaned the entire rack, with dishes, can be hung from the wall.
Here's a video that demonstrates how this whole thing works. We would love to have one of these in our house, especially since washing by hand wastes so much more water than using a dishwasher.
