RITI Printer Uses Your Coffee Grounds For Eco Ink

Jason S. writes to tell us that for those seeking to "go green" or those just wishing to try something different, RTI now offers a printer that uses coffee instead of ink. In addition to recycling your grounds, the printer also uses good old fashioned elbow grease to move the grounds cartridge back and forth, saving power. Sounds like a novelty that will die quickly as human sloth reasserts itself. "Hosted by Core77 and Inhabitat, this year's Greener Gadgets Design Competition resulted in an incredible crop of innovative consumer electronics designs, and we're excited to offer you the first scoop on some of our favorite designs! Jeon Hwan Ju's RITI printer works by replacing environmentally un-friendly inkjet cartridges with the dregs from your daily coffee. Simply place used grounds in the ink case, insert a piece of paper, and move the ink case left and right to print text."

Would this ink be able to be used for tattoos and would you get a permanent buzz if your tattoo was made of it? I am sure I already know the answer, but wouldn't that be just cool?
