A Hand-operated Printer!

Office printers consume energy and may even pose a health risk. But the hand-powered RITI Printer, designed by Jeon Hwan Ju, is different.

Power comes from the user, who has to pull the printer head back and forth as the paper is pulled through. Cleverly, the printer also does away with expensive ink cartridges, instead making use of waste coffee.

The printed product definitely smells of coffee, which some evidence suggests could help reverse the effects of sleep deprivation. And there's no word on how permanent a coffee-printed document is.
